Maybe in a future video dedicated to jumping in VR, I think it's interesting how with VR you can actually jump using something else than just the press of a button. Like press + moving both hands up like in lot of game.
Hey, I followed the tutorial and I'm having an issue at 12:19, For some reason the Bullet, Spawn Point, and Fire Speed options won't come up, Any way to fix this?
@@skortle4529 What I did was I copied the code exactly without copy and pasting anything. I got it wrong the first time because I copied and pasted some random guy's "copy" of the code and it didn't work. Just have Visual Studio and UA-cam open at the same time.
I'm having problemas with the Attach Point. It creates an attach point in the Right Hand controller, and it uses it instead of the empty object I created. But this attach point only appears in Play mode, so I can't add it as attach point to the pistol.
I've gone through the whole series and it's awesome and things are working great but I have one issue. While holding an object in one hand I am still able to grab it with the other, which makes some weird movement happen since the item is trying to match both hands, how would I fix this?
@@carsonlohr2781 I have a solution that works. Might not be the most elegant but it isn't too bad. 1. create an Attach Point for both Right and Left hands (attached to the Pistol object). Remember to adjust the values when playing BUT copy them when not playing. 2. Either add a second script to the pistol or extend the Fire Bullet On Activate (should prob be its own script) 3. The script will need public variables for Left/Right Attach Points and corresponding XR Direct Interactors. Entire script will be at the end to keep the instructions at the top! 4. Drag each of the GameObjects (attach points & interactors for both right and left hands) into the exposed variable slots in the editor. 5. Run the game and see that it works. For fun, I duplicated the pistol so i could dual wield! Here's the script I currently have: using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.XR.Interaction.Toolkit; public class FireBulletOnActivate : MonoBehaviour { public GameObject bullet; public Transform spawnPoint; public float fireSpeed = 20; public Transform leftHandAttachPoint; public Transform rightHandAttachPoint; public XRDirectInteractor LeftHand; public XRDirectInteractor RightHand; XRGrabInteractable grabbable; void Start() { grabbable = GetComponent(); grabbable.activated.AddListener(FireBullet); grabbable.selectEntered.AddListener(UpdatePosition); } public void UpdatePosition(SelectEnterEventArgs arg) { Object selectorHand = (Object) arg.interactableObject.firstInteractorSelecting; if (selectorHand == LeftHand) { grabbable.attachTransform = leftHandAttachPoint; } else if (selectorHand == RightHand) { grabbable.attachTransform = rightHandAttachPoint; } else { Debug.Log("Something's Broken"); } } public void FireBullet(ActivateEventArgs arg) { GameObject spawnedBullet = Instantiate(bullet); spawnedBullet.transform.position = spawnPoint.position; spawnedBullet.GetComponent().velocity = spawnPoint.forward * fireSpeed; Destroy(spawnedBullet, 5); } }
Hey, I've been loving these videos and I found them really helpful. But there's one issue. When I made the "Fire Bullet On Activate" script it doesn't compile and when I restart the tab, it says "The associated script cannot compile" I also have an issue where the Attach Point on the gun doesn't move the actual gun. I have to guess and check but eventually I get a really good position where it fits in the right hand perfectly, but then the left hand is super off. Any fixes for either of the two??
Hi! Your tutorial is super useful, thank you! :) I have a problem I could not fix though - I grab my weapon, let it go, grab again - works perfectly. But once I shoot, I cannot grab it again. Do you have any idea, why it could happen? I made a sci-fi scene with shootable ships, but the grabbing and shooting mechanisms are the same as yours.
I run into two problems: -> When I grab the pistol it seems to move if I use the right analog stick. For some reason the PistolObject uses the XR interaction Manager to move I believe. -> I am not able to grab the gun anymore. Even if delete the pistol and put it back in. Create a Colider and the xr grab interactible. it's broken. EDIT: I performed the seperation between Player Layer and Interactible layer, but still have this issue.
I had a similar problem. For some reason I had a Direct Interactor as a child component of my hands, which did not work. I deleted those and multi selected "Left Hand" "Right Hand", then added the XR Direct Interactor and the Sphere Collider. Now it's listening to my hands. In other words, double check your XR Direct Interactor and Sphere Collider are directly on the Hand components.
I figured it out thanks to an earlier comment (sorta). The cube was colliding with my body, sending it flying. So I put the cube and my body on two separate layers then unchecked where the met on the Physics matrix.
@@stryker2k2 im having the same problem, i made an XRorigin layer and left the cube on default, but what do you mena by "then unchecked where the met on the Physics matrix." because I want to fix this issue but dont understand what that meant.
Your tutorial was excellent, but I'm having trouble with the grab function, in my scene i have an object to grab, so i grab it but i have a continuous rotation script on my right hand so whenever i rotate with that hand, the grabbed object doesn't rotate with the hand.
hey, is that normal that when i try to grab an object the grab isn't grabbing but the pinch is grabing, how do i make some objects pinchable and other grabbable ?
Fantastic tutorial! However, I am having one problem, when I try to move the attach point during runtime, nothing happens, so I need to guess and check when moving the attach point.
you can drop and pick up the item quickly while moving it in the inspector, this allows you to slowly move it bit by bit, but its kinda frustrating and slow. @@mansourzawad
Same for me, it only moves the attach point but the pistol is not moving, hence i have to let go and grab again the pistol so I can know if now the attach point is positioned correctly.
Hi, I was wondering if it is normal for my oculus to like when I am testing my unity game I know this should not be right because I have a very new PC and it works fine playing any other game on oculus but once I test out my game. It likes uncontrollably.
Just add a LineRenderer as a child to your pistol ! Position it correctly, and set it to enabled and disabled just like we changed the color of the cube on Select Entered and Select Exited (at 4:22)
Go to Window - Package Manager (Packages: Unity Registry) - XR Interaction Toolkit (2.5.2) - Samples - Hands Interaction Demo - Click Import, then in the HandsDemoScene, you should be able to find the XR Interaction Manager under the "XR Interaction Hands Setup", you will need to copy paste it into your own Scene. Hope this can help you, took me so long to fix this. I think it's the XR Interaction Toolkit difference that causes the problem. 🧐
Change the size of your character controller component found within the XR origin so that you don't collide with the cube table. Make it slim, for instance radius, 0.1
He addressed this bug towards the end of the video. This is where he talked about setting the player and interactable layers. The cubes are causing a collision with your XR Origin, which in turn causes YOU to move backwards due to the physics interaction.
If someone wanted to use the trigger in order to grab certain objects, and the grip button to grab other objects, how might this be accomplished? Not me, asking for a friend, ofc.
@@carsonlohr2781 So to fix this go to the attach point you have already created scroll down until you find a checkbox that says something like “dynamic attach”
Hi :) I can't find the XR Grab Interactable script if I want to add the component. Up to this point everything went pretty well and I installed the XR Interaction Toolkit as learned in the previous videos. What did I wrong and how can I get the XR Grab Interactable script?
Really love your video's so helpful and thorough. Can I ask with the script at the start for making the teleport ray disappear, I implemented everything and it works perfectly on one hand but not the other. hand , the trigger appears but does not cause the user to teleport. I have double checked and both hands are set up the same way I have also tried remaking the ray components and then it switched where the hand that was working the first time round was broken the second time and visa versa. Any thoughts or help greatly appreciated.
Hey Valem! I am using your tutorials to create my VR Game. But for some reason the game is very laggy even with good settings a 1.5 GBPS link cable and a good pc it still lags with quest link! I have tried to use Virtual desktop but it doesn't open. What do you use to stream your game to your headset? I need to know!
Great Videos!! Thanks Valem. One Question. Since I can set my glasses to not turn off, I can't find any options. It gets complicated every time I want to test something that has to turn on controllers and goggles.
Is it possible to teach us how to activate the teleportation only while the thumbstick is pushed forward, and make it disappear if the thumbstick is released? this way it's possible to control when the teleport is active and cancel the action. Text instructions will be more than enough. I tried this myself but I don't know how to use the Vector2 value to trigger activation. Thank you so much for everything you do.
teleporter.SetActive((inputAction.action.ReadValue().y > 0.1F)); This works for me using the Locomotion/Teleport Mode Activate action on the teleporter game object
Hi, after adding the interactors and interactables the game gives me an error that Direct interactor does not have required collider set as a trigger. I also noticed that on the direct interactor on the interaction manager tab, for me it said none and for you it said it had one.
I have a problem where I always spawn at ground level. Resetting my position in vr fixes this, but it's kinda annoying to have to do that every time. Can anyone help? Great tutorials BTW :D
Maybe a silly question - but how are you managing to adjust the attach point transform so well while in game? In order to change the settings in Unity I have to let go of the controllers, take off the headset etc and it was not a smooth process at all
You can try to switch the "attach point compatibillty mode" to legacy for ajustments and then switch back to default. Guess its the newer toolkit version...

For the Fire Bullet script, can someone make it so they dissappear after colliding with something else, I have tried attempting this for so long yet it doesn't work. Help much appreciated.
You wouldn't add that to the Fire Bullet script. You would attach a script to the bullet prefab. The below script should help you out... Basically in the OnCollisionEnter function, you check to see what the bullet collided with. We need an exception for the pistol (you could make this more items too for more gun types). So long as it passes the IF check, then we call the Destroy function on the gameObject that the script is attached to (ie the bullets). using System.Collections; using System.Collections.Generic; using UnityEngine; public class DestroyOnCollision : MonoBehaviour { void OnCollisionEnter(Collision collision) { if (collision.gameObject.name != "pistol") { Destroy(gameObject); } } }

Hi, great tutorial. I have one question, I made a sword model that I can grab, but while using velocity tracking it lags behind my hand. Anyone else encountered this problem? Thanks.
@weHLDWNmiRWfxmvyKHzF Oh 100%. It solves entire physics aspect quite well. If you would compare the time it would take you to create this system by yourself and paying $50 for the complete thing, it is definitely worth it
How can I make the bullet stop colliding with another bullet or the player when moving forward? Basically, how can I make the bullet speed = some value + the player forward velocity? FYI, this isn't a layer issue currently, although I realise I need to look into this. EDIT: I created a bullet spawner that shifts forward based on the player's forward velocity to handle this edge case.
chatgpt suggestion.. need insert above line Destroy(spawnedBullet...: // Ignore collision between the spawned bullet and all other bullets. foreach (GameObject otherBullet in GameObject.FindGameObjectsWithTag("Bullet")) { if (otherBullet != spawnedBullet) { Physics.IgnoreCollision(spawnedBullet.GetComponent(), otherBullet.GetComponent()); } } // Ignore collision between the spawned bullet and the player. GameObject player = GameObject.FindGameObjectWithTag("Player"); if (player != null) { Physics.IgnoreCollision(spawnedBullet.GetComponent(), player.GetComponent()); }
@@pastuh note that FindGameObjects is expensive so should not be used where a large amount of objects need to be referenced in a short amount of time, say for example when trying to reference a lot of bullets from a machiene gun. For the odd reference its ok but better to reference another way than find if you can

Great video, it helped me a lot to get started in the world of VR development. I have just one question, is there any way to prevent the objects I grab from colliding with the player's collider without having to do it by code? I don't know, any option in XR Origin itself?

put ur finger on the things that say 1 2 or 3 and it tricks it into thinking u ahve ur headset on
@@HalfTayem Thank you :)
can you make a tutorial on how to make the force in unity like in the oculus game Vader Immortal?
Interesting topic I'll look into it :) thanks for watching
super helpful tutorial. do you plan on making a video on how to make the player jump?
Maybe in a future video dedicated to jumping in VR, I think it's interesting how with VR you can actually jump using something else than just the press of a button.
Like press + moving both hands up like in lot of game.
Was fun, feels almost like half life VR :))
I hope exist tutorial how to make animations for each different object.
Hey, could you teach us how to code a sword like in Blade and Sorcery?
Would be nice :) chop some trees in jungle
Hey, I followed the tutorial and I'm having an issue at 12:19, For some reason the Bullet, Spawn Point, and Fire Speed options won't come up, Any way to fix this?
I have the same problem, did you ever fix it?
@@thenoseguy Sadly not, I've given up on my VR Project for now :(
@@skortle4529 I figured it out. Just gimme a sec to remember how I did it.
@@skortle4529 What I did was I copied the code exactly without copy and pasting anything. I got it wrong the first time because I copied and pasted some random guy's "copy" of the code and it didn't work. Just have Visual Studio and UA-cam open at the same time.
make Shure there are no errors and that all of the code as a ; at the end of the line
I'm having problemas with the Attach Point. It creates an attach point in the Right Hand controller, and it uses it instead of the empty object I created. But this attach point only appears in Play mode, so I can't add it as attach point to the pistol.
I can't fire the bullet...i have problem with script
I've gone through the whole series and it's awesome and things are working great but I have one issue.
While holding an object in one hand I am still able to grab it with the other, which makes some weird movement happen since the item is trying to match both hands, how would I fix this?
If you get a reply let me know.
@@carsonlohr2781 I have a solution that works. Might not be the most elegant but it isn't too bad.
1. create an Attach Point for both Right and Left hands (attached to the Pistol object). Remember to adjust the values when playing BUT copy them when not playing.
2. Either add a second script to the pistol or extend the Fire Bullet On Activate (should prob be its own script)
3. The script will need public variables for Left/Right Attach Points and corresponding XR Direct Interactors. Entire script will be at the end to keep the instructions at the top!
4. Drag each of the GameObjects (attach points & interactors for both right and left hands) into the exposed variable slots in the editor.
5. Run the game and see that it works. For fun, I duplicated the pistol so i could dual wield!
Here's the script I currently have:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.XR.Interaction.Toolkit;
public class FireBulletOnActivate : MonoBehaviour
{
public GameObject bullet;
public Transform spawnPoint;
public float fireSpeed = 20;
public Transform leftHandAttachPoint;
public Transform rightHandAttachPoint;
public XRDirectInteractor LeftHand;
public XRDirectInteractor RightHand;
XRGrabInteractable grabbable;
void Start()
{
grabbable = GetComponent();
grabbable.activated.AddListener(FireBullet);
grabbable.selectEntered.AddListener(UpdatePosition);
}
public void UpdatePosition(SelectEnterEventArgs arg)
{
Object selectorHand = (Object) arg.interactableObject.firstInteractorSelecting;
if (selectorHand == LeftHand)
{
grabbable.attachTransform = leftHandAttachPoint;
}
else if (selectorHand == RightHand)
{
grabbable.attachTransform = rightHandAttachPoint;
}
else
{
Debug.Log("Something's Broken");
}
}
public void FireBullet(ActivateEventArgs arg)
{
GameObject spawnedBullet = Instantiate(bullet);
spawnedBullet.transform.position = spawnPoint.position;
spawnedBullet.GetComponent().velocity = spawnPoint.forward * fireSpeed;
Destroy(spawnedBullet, 5);
}
}
Hey, I've been loving these videos and I found them really helpful. But there's one issue. When I made the "Fire Bullet On Activate" script it doesn't compile and when I restart the tab, it says "The associated script cannot compile" I also have an issue where the Attach Point on the gun doesn't move the actual gun. I have to guess and check but eventually I get a really good position where it fits in the right hand perfectly, but then the left hand is super off. Any fixes for either of the two??
Hello. That's a fantastic video! Is there a way to set the movement type to Velocity Tracking in the Meta XR All-in-One SDK?
Hi! Your tutorial is super useful, thank you! :)
I have a problem I could not fix though - I grab my weapon, let it go, grab again - works perfectly. But once I shoot, I cannot grab it again. Do you have any idea, why it could happen? I made a sci-fi scene with shootable ships, but the grabbing and shooting mechanisms are the same as yours.
I run into two problems:
-> When I grab the pistol it seems to move if I use the right analog stick.
For some reason the PistolObject uses the XR interaction Manager to move I believe.
-> I am not able to grab the gun anymore. Even if delete the pistol and put it back in. Create a Colider and the xr grab interactible. it's broken.
EDIT: I performed the seperation between Player Layer and Interactible layer, but still have this issue.
Would you happen to know if there is a way to change how the hand grips around whatever object you are trying to grab?
i think it grabs the center, so u have to make the center of the collider where the hand goes (tbh im a noob at unity but ig try it)
I have a problem, 4:58 when I grab the cube it doesn't turn yellow. it turns white when i touch the cube but doesn't turn yellow when i grab the cube
I had a similar problem. For some reason I had a Direct Interactor as a child component of my hands, which did not work. I deleted those and multi selected "Left Hand" "Right Hand", then added the XR Direct Interactor and the Sphere Collider. Now it's listening to my hands.
In other words, double check your XR Direct Interactor and Sphere Collider are directly on the Hand components.
Whenever I grab the cube, I get launched a thousand miles into the air. Has anyone else ran into that issue?
I figured it out thanks to an earlier comment (sorta). The cube was colliding with my body, sending it flying. So I put the cube and my body on two separate layers then unchecked where the met on the Physics matrix.
@@stryker2k2 im having the same problem, i made an XRorigin layer and left the cube on default, but what do you mena by "then unchecked where the met on the Physics matrix." because I want to fix this issue but dont understand what that meant.
3:05 OUR OLD HANDS!
We've come so far
Your tutorial was excellent, but I'm having trouble with the grab function, in my scene i have an object to grab, so i grab it but i have a continuous rotation script on my right hand so whenever i rotate with that hand, the grabbed object doesn't rotate with the hand.
Nevermind, i found the problem. Great video again.
hey, is that normal that when i try to grab an object the grab isn't grabbing but the pinch is grabing, how do i make some objects pinchable and other grabbable ?
Fantastic tutorial! However, I am having one problem, when I try to move the attach point during runtime, nothing happens, so I need to guess and check when moving the attach point.
I have this same problem?
i'm having the same problem. have u found a solution for this?
you can drop and pick up the item quickly while moving it in the inspector, this allows you to slowly move it bit by bit, but its kinda frustrating and slow. @@mansourzawad
Having the same issue. Is there not a setting to allow it to edit in runtime?
amazing video, but my hands have red lines that let me pick things up from across the map
Great Video thank you soo much
Thanks for watching
the trick with moving the attach point while holding the gun doesnt work for me, the attach point works but i just cant do the trick
Same for me, it only moves the attach point but the pistol is not moving, hence i have to let go and grab again the pistol so I can know if now the attach point is positioned correctly.
Hi, I was wondering if it is normal for my oculus to like when I am testing my unity game I know this should not be right because I have a very new PC and it works fine playing any other game on oculus but once I test out my game. It likes uncontrollably.
my interactions are not working when i use xr device simulator. I dont my headset with me ryt now, how do i solve this issue?
Hey @Valem Tutorials, is there a possible way I can make a line for the pistol so I know where it exactly shoots?
Just add a LineRenderer as a child to your pistol ! Position it correctly, and set it to enabled and disabled just like we changed the color of the cube on Select Entered and Select Exited (at 4:22)
@@Xarius, thank you so much!!!
how do i get the XR Interaction Manager?
Go to Window - Package Manager (Packages: Unity Registry) - XR Interaction Toolkit (2.5.2) - Samples - Hands Interaction Demo - Click Import, then in the HandsDemoScene, you should be able to find the XR Interaction Manager under the "XR Interaction Hands Setup", you will need to copy paste it into your own Scene. Hope this can help you, took me so long to fix this. I think it's the XR Interaction Toolkit difference that causes the problem. 🧐
Hello Valem! Great tutorial! Question:Why does my desk move back (keep away) when I grab for the cube ? 😂 Expecting a reply
It doesn’t move away your just not moving forward because of the collision
Change the size of your character controller component found within the XR origin so that you don't collide with the cube table. Make it slim, for instance radius, 0.1
the cube is prob to far away, if you try to walk irl it wont let you
He addressed this bug towards the end of the video. This is where he talked about setting the player and interactable layers. The cubes are causing a collision with your XR Origin, which in turn causes YOU to move backwards due to the physics interaction.
Why when I put an object that I take with my hand, does it lift or move me?
If someone wanted to use the trigger in order to grab certain objects, and the grip button to grab other objects, how might this be accomplished?
Not me, asking for a friend, ofc.
Is there a way that you can make it a different grab like a trigger grab?
When I try to throw the cubes away in the plane... the cube just somehow bypasses the plane and start falling. Can someone please help?
so when I try to grab the cube it doesn't do anything.
How do I edit the attatch point for both hands? For my left hand the gun position is perfect but it makes it worse when I grab it with my right hand.
Yes! have you found anything?? I cant find anything
@@carsonlohr2781 So to fix this go to the attach point you have already created scroll down until you find a checkbox that says something like “dynamic attach”
@@cloudd_08 where do i find that
I have a problem. when I shoot the bullet goes to the left and not forward. How do I fix this?
Hi :) I can't find the XR Grab Interactable script if I want to add the component. Up to this point everything went pretty well and I installed the XR Interaction Toolkit as learned in the previous videos. What did I wrong and how can I get the XR Grab Interactable script?
Really love your video's so helpful and thorough. Can I ask with the script at the start for making the teleport ray disappear, I implemented everything and it works perfectly on one hand but not the other. hand , the trigger appears but does not cause the user to teleport. I have double checked and both hands are set up the same way I have also tried remaking the ray components and then it switched where the hand that was working the first time round was broken the second time and visa versa. Any thoughts or help greatly appreciated.
Did you find a fix for this? I also have my rays working but the teleporting won't go off. If I disable this script, teleporting works fine
Hey so I fixed by resetting the XR Controller component, make sure each interactor has it's own tied to the game object
Hey Valem! I am using your tutorials to create my VR Game. But for some reason the game is very laggy even with good settings a 1.5 GBPS link cable and a good pc it still lags with quest link! I have tried to use Virtual desktop but it doesn't open. What do you use to stream your game to your headset? I need to know!
Great Videos!! Thanks Valem. One Question. Since I can set my glasses to not turn off, I can't find any options. It gets complicated every time I want to test something that has to turn on controllers and goggles.
Is it possible to teach us how to activate the teleportation only while the thumbstick is pushed forward, and make it disappear if the thumbstick is released? this way it's possible to control when the teleport is active and cancel the action. Text instructions will be more than enough. I tried this myself but I don't know how to use the Vector2 value to trigger activation. Thank you so much for everything you do.
teleporter.SetActive((inputAction.action.ReadValue().y > 0.1F));
This works for me using the Locomotion/Teleport Mode Activate action on the teleporter game object
@@martwoods Thank you, sir! That .y after vector 2 is exactly what I needed! I had figured it out, but I hope this can help someone else.
Hi, after adding the interactors and interactables the game gives me an error that Direct interactor does not have required collider set as a trigger. I also noticed that on the direct interactor on the interaction manager tab, for me it said none and for you it said it had one.
hi, the error might come from not checking "isTrigger". go to your hand object -> sphere collider -> check is Trigger
@@yoOtzel Yup its this. I had the same problem, thanks for the help.
@@Sssenstional i'm glad i could help ;)
I have a problem where I always spawn at ground level. Resetting my position in vr fixes this, but it's kinda annoying to have to do that every time. Can anyone help? Great tutorials BTW :D
Maybe a silly question - but how are you managing to adjust the attach point transform so well while in game? In order to change the settings in Unity I have to let go of the controllers, take off the headset etc and it was not a smooth process at all
i had same problem. you solved it?
@@juanbrincadeira no, i ended up just copying his values from the video but i also want to know how to do it conveniently for future use
You can try to switch the "attach point compatibillty mode" to legacy for ajustments and then switch back to default. Guess its the newer toolkit version...

For the Fire Bullet script, can someone make it so they dissappear after colliding with something else, I have tried attempting this for so long yet it doesn't work. Help much appreciated.
You wouldn't add that to the Fire Bullet script. You would attach a script to the bullet prefab. The below script should help you out... Basically in the OnCollisionEnter function, you check to see what the bullet collided with. We need an exception for the pistol (you could make this more items too for more gun types). So long as it passes the IF check, then we call the Destroy function on the gameObject that the script is attached to (ie the bullets).
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class DestroyOnCollision : MonoBehaviour

void OnCollisionEnter(Collision collision)

Destroy(gameObject);

Hi, great tutorial. I have one question, I made a sword model that I can grab, but while using velocity tracking it lags behind my hand. Anyone else encountered this problem? Thanks.
@weHLDWNmiRWfxmvyKHzF Sorry not sure how you would fix this. I decided to go with Hurricane VR where this is solved.
@weHLDWNmiRWfxmvyKHzF Oh 100%. It solves entire physics aspect quite well. If you would compare the time it would take you to create this system by yourself and paying $50 for the complete thing, it is definitely worth it
i need some help whenever i get too close with my hands to an object i move a little bit backwards is there any way to fix it
might be late but for me my fix was decreasing the size of the radius on the character controller.
How can I make the bullet stop colliding with another bullet or the player when moving forward? Basically, how can I make the bullet speed = some value + the player forward velocity? FYI, this isn't a layer issue currently, although I realise I need to look into this.
EDIT: I created a bullet spawner that shifts forward based on the player's forward velocity to handle this edge case.
chatgpt suggestion.. need insert above line Destroy(spawnedBullet...:
// Ignore collision between the spawned bullet and all other bullets.
foreach (GameObject otherBullet in GameObject.FindGameObjectsWithTag("Bullet"))
{
if (otherBullet != spawnedBullet)
{
Physics.IgnoreCollision(spawnedBullet.GetComponent(), otherBullet.GetComponent());
}
}
// Ignore collision between the spawned bullet and the player.
GameObject player = GameObject.FindGameObjectWithTag("Player");
if (player != null)
{
Physics.IgnoreCollision(spawnedBullet.GetComponent(), player.GetComponent());
}
@@pastuh note that FindGameObjects is expensive so should not be used where a large amount of objects need to be referenced in a short amount of time, say for example when trying to reference a lot of bullets from a machiene gun. For the odd reference its ok but better to reference another way than find if you can

can someone help me i cant do the attach point part with the gun when i move the attach point hte gun dosent move????????????????

Try letting go and grabbing again fast enough to see the change.
When I grab anything: it's very jittery and doesn't like to follow my hand well
When I pick up an object and then move the joystick of the same hand, the object moves with the joystick faster than I move, so the object leaves my hand. Is anyone else having this problem?

Great video, it helped me a lot to get started in the world of VR development.

I don't know, any option in XR Origin itself?
Yes, layers. Its really simple :D
Problemm :Direct Interactor does not have the required Collider as trigger.?????
When I set my grabbable objects onto a different layer, they disappear when I go into play mode 😮 I’m confused.
hello any idea why my left controller uses select to grab the objects but my right controller is using the activate trigger, i can't find out where to change it and now i can really pick up the gun as the teleport always activates

Hi, I've got an issue. I cannot grab interactables with left hand controller. Right one works fine. Do you have any ideas how ould I fix this?
You might have forgotten to add a collider with isTrigger set to true for the left hand.
(FIX): my collider was not in the correct position reletive to the hands, make sure your sphere collider in both the right and left hands are at 0,0,0
Currently having a problem with the objects interacting with my custom made hands in blender, i keep getting to message "NullReferenceException: Object reference not set to an instance of an object", also im having problems with the teleportation ray/radical showing (i have the right hand unchecked but the left wont work), can anyway please help me.
Idk if this helps, but i got the ray/radical working, and realized that it turned white when the ray was touching the cube, if i click trigger it turns yellow.
