This is so cool! Thx !
That's not a problem at all! :)
Best explains ever thanks alot
I really appreciate that, thanks for watching my dude! :D
Thank you so much @SpeedTutor
No worries at all! :D
this tutorial could come in handy in making my game thx so much
I hope so, thanks for coming along to watch! :D
Hey Great Tutorial, with some few tweaks I was able to implement this script into my 2D Game. Good job!
Amazing! I'm glad it was helpful! :D Best of luck with your game.
Cool, thank you dude!
No problem at all, glad to have you here! :D
thank you!
You're welcome! Thanks man! :D
thank you! it works for my 2D game. i had to add a boolean "canSprint" because if my stamina was regenerating after complete exhaustion i could still hold the sprint key and the slider would not fill up while doing that but i also did not move faster. now it works fine :D
Great work! :D Best of luck with your project too!
Hello so I love your video, it had all the things I needed for a stamina bar but I am using the new input system and I'm not sure how to like fix it up so that it references the new input system than the old one.
This is the only tutorial I could found that hide the bar and only is visible during sprint. Thank you
Haha, I'm glad you found this helpful. Thanks for coming to watch! :)
thanks
You're welcome!
hi, its good tutorial, but i have a problem:
NullReferenceException: Object reference not set to an instance of an object
StaminaController.StaminaJump() in this string "playerController.PlayerJump();"
and this
NullReferenceException: Object reference not set to an instance of an object
StaminaController.Update() in this string "playerController.SetRunSpeed(normalRunSpeed);"
for some reason the speed changes to sprinting speed after I get back my stamina after I run out of it
them :Should we bow?
Me: Yeah he is a king.
SpeedTutor dude when I keep my Stamina Regenerating, sometimes it hits until 99 and I can't able to sprint anymore, it creates a bug.
(45,34): error CS0246: The type or namespace name 'StaminaController' could not be found (are you missing a using directive or an assembly reference?)
Is your script name the same as your class name?
Hi! How do I make it so that the Stamina only recharges when I'm not moving?
You could check if the character is grounded and you're not pressing any input, then regenerate! :)
@@SpeedTutor OK thank you so much :D
@@SpeedTutor OK but what exactly do you need to write?
how could i go about using the sprint option for this outside of the standard asset like when i hold mouse 1 it drains ? like with a weapon for example
Just do an Input within your update method, use .deltaTime to make it happen over time, effect a variable and make sure to takes away from your UI! :) Or whenever you click OnMouseDown, you take away one. It depends what you're doing! :)
Great tutorial, in case anyone else still uses this just wanted to toss in there that changing
if (!areSprinting)
{
if (Stamina
Awesome, thanks for the suggestion my friend! :)
10:50 isnt just asking for "playerStamina >= jumpCost" the same? What is that calculation doing or am i missing something?
I think you're exactly right, it was probably an oversight from me. Haha.
Did you make this movement script in a prior tutorial? It looks amazing :D
That movement script is just from the standard assets, the FPS controller that has been around a long time! :)
@@SpeedTutor thank you
where can i find it?@@SpeedTutor
@@thatoneearthdev Sadly it's not on the asset store anymore, you can check out my video on finding them. If you search "Standard Assets" on my channel. If not, I think they're still on my Patreon too.
yeah, just found out they dont exist anymore@@SpeedTutor
Assets\Standard Assets\Characters\FirstPersonCharacter\Scripts\FirstPersonControllerCustom.cs(44,34): error CS0246: The type or namespace name 'StaminaController' could not be found (are you missing a using directive or an assembly reference?)
Is the script name the same as the class name?
Does anyone know how to fix the type or namespace name UnityStandardAssets could not be found (are you missing a using directive or an assembly reference?) 5,7
Did you add the namespace at the top?
Hi, thankyou for the tutorial, you explain it well. :)
One issue I have is when I press Lshift the stamina bar goes down in increments instead of smoothly, any idea why?
Which part of the script allows the stamina to drain smoothly?
As far as I remember it should drain smoothly as it's using Time.deltaTime; isn't it?
@@SpeedTutor Yeah it is, Ill have a look
i think its a misspell from me but unity cant find the stamina controller script
FirstPersonControllerCustom.cs(45,34): error CS0246: The type or namespace name 'StaminaController' could not be found (are you missing a using directive or an assembly reference?)
Did you fix it?
not really, the names seem to be matching yet unity still mistakes the script for a namespace
@@SpeedTutor
@@TikyTheEspresso same were you able to fix it?
I have a problem on the line 44 of the First person controller custom, it says "error CS0246: The type or namespace name "staminaController" could not be found
What code is on that line?
im pretty sure its the same "public StaminaController _staminaController"
@@SpeedTutor
Could you please explain how you manage the speed value? Because it's impossible understand at the end of the video since you change the speed value from the stamina script but don't explain where ans how you use it! I think is the key to understand the video! Thanks
Give me the timing that I do it, I'll rewatch my video and try to explain it for you! :)
@@SpeedTutor Thanks!
I meant, could you tell me what time in the video you have a problem with? I'll look over it and explain? :)
hey, once i jump once my player keeps jumping on his own nonstop without me pressing anything, any ideas why?
That's really weird, sounds more like an issue with your player controller?
Hi sorry when it hits zero and run button is still being pressed it will go up but after that won't sprint or drain how can I fix that? also great video thanks
I think someone had a solution in the comments, as I recall :)
@@SpeedTutor Oh ok I will check again thanks :D
So according to my First Person script, the Stamina Controller class name isn't a thing, but I put the name of my script the exact same thing as my class name
help me please answer
So what's the error?
I can't even access the namespace Stamina Controller in the FIrstPerson script
@@private_channel I too had a problem where I couldn't find the reference of StaminaController. When he changes the name of the FirstPersonController script to FirstPersonControllerCustom, you need to make sure you are using the right one
Hello, how can I make it so that he can run not until the stamina bar reaches the end, but so that he can run when he gains a small amount?
Make sure that you're checking to see if there is stamina when you're pressing the key :)
@@SpeedTutor Thanks, I already figured it out myself, it's just to add the code there, if the stamina scale is more than 0, then he can run)
Awesome, good job! :D
@@SpeedTutor thanks)
Hi ST. maxStamina * jumpCost / maxStamina = jumpCost ? i don't understand why we write this equation ? Couldn't we write simply playerStamina>= jumpCost ?
What part of the video is this?
@@SpeedTutor if block (time:10:43)
You're right, I'm not sure why I did that! Haha. You're smarter than me! :)
@@SpeedTutor haha u re best.) I am only carefull
I have a doubt sir. In my game, I am having a shooting bar. Which means , If I hold the shoot button, then the shooting bar gets decreased and if the bar is at 0 then the player should stop shooting. And the shooting bar regenerates. Problem is if I press the shoot button it is decreasing but it is not stopping to shoot. It is continuously shooting after bar is at 0 while holding the button. And I solved this problem by using setactive. But after that, another problem came, that is, if I press the button, it is not shooting after the bar is 0, yeah that's fine, but the bullets are only disabled, so it is creating many disabled bullets in hierarchy. What should I do sir plz 😥😥
So you could check when the bullets go back up again and re-enable your actions?
@@SpeedTutor oh yeah thanks for the tip sir.
When running the code there was an error (Error CS0246 to be exact) and it said that the namespace name "UnityStandardAssets" could not be found. Is there any fix for this?
Did you add "Using UnityEngine.StandardAssets.FirstPerson"? I can't remember the exact name space.
@@SpeedTutor Yes. The namespace was "UnityStandardAssets.Characters.FirstPerson"
You've imported the Standard Asset Character?
@@SpeedTutor no, I didn't.
why i move around (not sprinting) stamina is drained?
I'm not sure, are you sure the script is correct?
(72,16): error CS0029: Cannot implicitly convert type 'float' to 'bool'
(77,33): error CS0120: An object reference is required for the non-static field, method, or property 'CharacterController.velocity'
(86,37): error CS0029: Cannot implicitly convert type 'bool' to 'float'
What lines are these on?
@@SpeedTutor (72,16): error CS0029: Cannot implicitly convert type 'float' to 'bool'
(77,33): error CS0120: An object reference is required for the non-static field, method, or property 'CharacterController.velocity'
(86,37): error CS0029: Cannot implicitly convert type 'bool' to 'float'
Do you have a way to apply this to a 2D game, where the movement script is all the bare minimum user made?
does this work with my own firstpersoncontroller.
It would if you integrated it in a similar way but it depends how yours is programmed! :)
Weird, it seems everything else works except the Stamina Bar. It doesn't seem to change when I sprint and jump. On sprinting and jumping, the bar doesn't appear when I already set the alpha of the Canvas group to 0. There isn't an error message telling me what the problem is either. Any Ideas?
What about if you add a debug log to see if the part in the code fires? If not, you need to investigate why it never does :o
@@SpeedTutor Thx for the fast response! I added a debug log for all of the methods and they all seemed to work just fine. However, when adding a debug log to the following code in UpdateStamina() method, the debug.log did not run (Note that my CanvasGroup Alpha = 0 and I am stationary):
if (value == 0)
{
sliderCanvasGroup.alpha = 0;
Debug.Log("Test");
}
My CanvasGroup's Alpha was not changed to 1 when I started sprinting and jumping around. I'm relatively new to Unity and C# so please bear with me! (Hopefully I'm not breaking any rules by sending code here)
EDIT: It is only the Stamina Bar display that is not working.
You have the if statement of value. What is "value"? Don't worry, haha. I'll try my best to help but it's tough when I only see part of the picture. Haha.
@@SpeedTutor According to the video, "value" is from the UpdateStamina method:
void UpdateStamina(int value)
{
staminaProgressUI.fillAmount = playerStamina / maxStamina;
if (value == 0)
{
sliderCanvasGroup.alpha = 0;
}
else
{
sliderCanvasGroup.alpha = 1;
}
}
EDIT: Debug.Log fires in the else portion of the code when sprinting but does not fire when stationary. The Stamina Slider bar does not appear either.
Ok, if that's the case. Can you change alpha value of the canvas group when you're in-game? Just from the inspector?
i know this is a bit old but can you help me? my player stamina doesn't regen all the way to 100, it stays at 99.*(random numbers) and then i cant run anymore
At what level does it check when it's full?
@@SpeedTutor i added
if (playerStamina >= maxStamina)
hasRegenerated = true
but idk why it just doesnt go to 100
Create a debug line in that code to check if it ever goes to 100?
@@SpeedTutor i did it sometimes it runs it sometimes it doesn't. I just did a test now and sometimes it's goes to 100% and works perfectly and sometimes it says at 99.99771 or 99. other numbers, and if stamina is not at 100 or more it doesn't set hasRegenerated to true, and then I can't run.
@@SpeedTutor i fixed it by checking if the stamina is above 99 instead of 100
How can I make it that when its regenerating I can sprint?
Take away the check to stop the check for whether stamina is full again?
@@SpeedTutor When I spend all of my stamina and it starts to regenerate again I can't sprint(when I try to sprint it only stops regenerating stamina) but I can jump. What line or part of code do I have to remove to disable that?
@@cecavacd i think its line 63 playerController.SetRunSpeed(slowRunSpeed); If the player stamina is less than or equal to 0, the speed is set to slow
SPEEDtutor
Are you trying to say this is good or bad? Haha.
@@SpeedTutor The speedtutor teaching about speed!
Haha, I hope it was speedy enough for you! :D
i cant reference the StaminaController inside the standarasset script :c
Whats happening?
@@SpeedTutor nothing. fixed. love you
How did you fix it?
@@SpeedTutor both scripts need to be in the same folder
"works with your own character controller script"
proceeds to show a method that does not work with a normal character controller script
The logic applies to all types, it's just the direct implementation of affecting your players stamina, speed and so on which is very dependant to the controller.
@@SpeedTutor sorry for being rude. I was just extremely mad at the fact that after hours of coding, this didn't work with my script
No worries my dude, I can understand how frustrating things are. Especially when you have to transfer the logic to something else. Believe me, I go through nightmares on a daily basis! Haha.
Can someone PLEASE HELP it says StaminaController could not be found
Is the class name the same as the script name?
@@SpeedTutor I believe their problem comes from changing the name of the FirstPersonController script to FirstPersonControllerCustom,
why i can't access this (StaminaController) to (FirstPersonController) i follow every steps but still error :(
Did you make everything public?
@@SpeedTutor i fix it already but my problem now is when i stop the sliding bar is not increasing but in the inspector is increasing not in vision any idea bro what i missed i did every step
@@kazrepair7219 It sounds like its something to do with your stamina sliders, Over in Stamina Controller script (Stamina UI Elements in the inspector), make sure the stamina progress UI is not set to the background slider.
@@kazrepair7219 how did you fix it? I can't reference the script into the FirstPersonController one
this is a shit ton of code for something so simple
Haha, there might be more refined ways to do it but nothing is usually simple to make systems work. :)
