بارك الله فيك و جزاك كل خير🤍
I look forward to the continuation of your classes. I wish you and your loved ones health and happiness.
Thank you Kenan, same to you!
Finally found a beginner friendly tutorial, thanks!
I clicked this away 2 times because i thought this cant be rigt/up-to-date, being 3 years old. BUT this is up to date AND on Point!
Thank you very much for this Video.
Managed to implement some smooth animation transitions in a 2D platform game thanks to this, great content!
Hi, what a great tutorial series! I watched them all and I must say these are THE BEST tutorials on Godot and game development in general I watched both in youtube and Udemy. You MUST continue your lessons even in paid form, your knowledge is vast and the lessons are professionally structured. Please do more, maybe on strategy games.
Thx Delyan! I got more planned for the fall season of this year :) Never going to be paid, I believe educational content shouldn't have a price
This is the best tutorial ever made on animation tree
Excellent tutorial. saves several lines of code with this method making it cleaner!
Yeah, loving this node and glad I finally got a tutorial on it :)
ty, it's awesome. i couldn't figure it out from the documentation, but i think it's more my inexperiene in statemachines with animation. details of the state are handled in that blendroom, state transition handled on an statemachine tree.
Yeah, the animationtree can do so much it is easy to get lost in it :)
Please don’t stop doing godot tutorials!!! It’s so helpful!!! I wish you the best!!!
Thx Manal, not planning on stopping any time soon :)
"(0,1)"... Perfect! 😁
Def a credit to the godot community.
thanks for explaining so clearly
I would love to see more on the Ysort method like you did for tilemaps. The coding to change sprite pictures when interacted with etc. since there is no tilemap coordinates to reference.
Yeah, I have been planning something with layered spritesheets. To reflect changing equipment for example :)
@@nosywendigo592 Yeah something like that gives the game a boost in immersion :)
amazing. well explained, great example.
wow u answered all my questions
much love
Awesome great to hear that Salem!
Man, I really like your tutorials!
I appreciate that Supernova, I love the name! Big space nerd here!
tyvm
Thank you very much.
I used to make games with the Microsoft XNA framework, and in that framework I had animations with smooth transitions between walking and idle. So when the player starts walking, it first lifts its right leg before the walking animation starts, and when you stop walking from any frame, the correct leg will retract and the player will stand idle again. Back then it was all code, but now in Godot for example I'm kind of lost on how to handle these "smooth transitions".
I am an animation freak, I just like to overcomplicate 2d Sprite animations lol.
In 2d, you just need the sprites for that if you use a spritesheet. Otherwise look into 2d skeletons. Honestly, just go 3d when you go to that level. And orthographically render it with a viewport. Much easier, faster, and better results.
@@GameDevelopmentCenter I'm looking for a 2d pixel look tho. So is it possible to just use a 3D model and render it as 2D pixel art? Because otherwise it's back to square one and create sprites from a 3D model again.
woah finally animation tree, thanksss
Yeah, putting the concepts of the animationtree into clear wording was a challenge :)
you can change the north south thing from around 9:00 by taking the axis labels and changing them, this can also be used to scale, but flipping is just scaling by -1 so...
sorry if im, wrong, i haven't tried it, but it looks possible
I think I tried this,and other things, to no avail. It seems to be locked this way. It is quick to get used to :)
very helpful and easy to understand!Subscribed!
Thx Kizz! Happy to hear you found this helpful :)
Your content is very helpful thank you for these videos.
You're very welcome!
great tutorial as always.
Thank you! Cheers!
Great tutorial. Recommended.
Thx Paul!
Just s recommendation, when watching on mobile, the code font is too small to see properly
92% of my viewers are on desktop, I know it is small on mobile, but really, who watched coding tutorials on mobile? Almost nobody cause there isn't enough screen real estate.
Any Idea why i would be able to look a a diff direction while walking in another direction?
Im using click to move btw
Could be several reasons. From mislinking the animations in the 2d animation grid to passing the wrong blend position in code
Great tutorial. Just a nitpick technically to align the the blend space coordinates for the animations NE,NW,SW,SE they should be placed at the respective point (-1, 0.5), (-1, -0.5), (1, -0.5), (1, 0.5)
That is incorrect as this is isometric art.
For top-down or forward angled, you would be right :)
@@GameDevelopmentCenter I still don't quite understand it
In isometric: y = 1/2 * x. That makes the normal vector for diagonal movement x axis biased at (0.8, 0.6)
@@GameDevelopmentCenter Thank you for the help
I think you can just change the values of -1 and 1 in the blend tree...simply put a +1 where -1 is and vice versa....I know you can change the values so...why not?
Didn't work for me.
For the algorithm :D
Very nice tutorial man, earned my sub! Quick question though, how would you setup an animation tree to work on an enemy that moves on its own? Because you wouldn't use any user input to determine the blend position like you've done here since the enemy is moving by itself. I've currently got an npc that moves on a path using a Navigation2D node but I'm having a hard time getting that to work with my animation tree and animation player since I can't get those normalized directional values from the automatic movement.
On every physics frame you can save the current position to a value, and compare that to the position of entity on the next frame. Those are 2 Vector2, which you can compare and normalize. That would be your movement direction updated every frame as input for the blend position.
@@GameDevelopmentCenter thanks! i tried this out and it's working perfectly!
The transitions in the blendspace are not smooth for me.
When you change direction, it restarts the animation. Say if you go from North to NE. I use 8-directional movement and it looks very obvious that the animations are restarting. I know how to make it work in script, but I would have to avoid using the AnimationTree which is a bit unfortunate.
That probably means you made an error somewhere
For some reason when I press play on the walk or idle animations, they won't play. It'll show the first frame of their animation, and that's it. I'm pretty sure this is a problem with the animationplayer, but I'm not sure how to fix it. When previewing the idle or walk blendspaces, the direction updates correctly, the animation just doesn't play.
Join the Discord, UA-cam comment section is not a good tool to have a conversation about debugging
Very nice tutorial, thank you!
How to change blend position in animation blend space 2d with code?
I have a points in it with animations
Like 0 is idle frame, 0.5 is another, etc
In viewport when I move this parameter it works perfectly for my needs. But I don't know how to manipulate it within the code
I need to manipulate only x axis
So I tried to create a var blend_position = $animation_player.get("parameters/blend_position")
And then in process
blend_position.x += 0.5
And this doesn't have any effect
I'm not sure if I understand your questions, but based on what you are saying: 'I need to manipulate only x axis'. I think you better be using the blendspace1d
@@GameDevelopmentCenter blend space 1d doesn't work for some reason, in blend space 2d i created a point higher than 0 for get rid of error and it works well in viewport
@@ruslanakhmadov5870 Well if the code I have in the tutorial doesn't change the blendposition something else is wrong. Easiest would be to post a screenshot on discord so I can help you faster :)
How do you create this animation tree purely in gdscript if you are loading animations via gdscript and they aren't already in the editor?
I honestly have no experience with that, but I imagine you will have to build the animation tree after loading this animations.
@@GameDevelopmentCenter no worries- I managed to figure it out after searching around and trying various things.
Since the spritesheet in my project only has right facing frames for idle, attack, jump, etc, and I'm relying on flip_h (since it's a platformer, not top down) I can pretty much ignore the whole blendSpace2D, right?
I would even go as far as that you can ignore the whole animation tree node. Setting thing up in just code is probably just as much trouble. Without any major benefit.
I've been following along without much issue, however for some reason the animations within the game aren't showing for RunNE. Somtimes It will show IdleNE instead, or it will just play the last animation again. This is the only one giving me trouble. I have checked all the points in AnimationTree, all the animations are created properly, and when I manually test the position in AnimationTree it shows the proper animation.
Any ideas what might be causing this? The only thing i've done differnet from the tutorial thus far is bringing in my animations using the AnimatedSprite from individual files. But everything I've seen so far is indicating my animations are fine. It's just at run time, it won't play RunNE. When I run that direction and the character stops, it shows the IdleNE just fine. I'm so confused :D
Did you turn blend off? Common issue.
how do i make all my animations from animation player be included in the parameters of animationtree so that i can control them? is it done with statemachine with 3d?
Inside which parameters?
What if I wanted the animation tree to work automatically..... like for enemy ai
Integrate it with the statemachine you will build to implement your enemy logic
Hi Sensie (i want to u call u that). Pls make a tutorial - * on mouse click (or finger touch) the enemy sprite will vanish (with animation). * Enemy sprites appearing randomly in different places.
Hi pmlpvd Lte, thank you for your request, but this is a very specific game feature that not many people will be looking for. I think the best thing to do for you is follow multiple tutorials for various topics. Learn the concepts and the pattern so that you can design such a specific game feature yourself :)
i keep getting null when i use this like in the video.
onready var playback = get_node("AnimationTree")
onready var playback_mode = playback.get("parameters/playback")
it only works if i put it in a function other than _ready(), _physics_process() or _process
Sorry for getting back to you after days OptimoJoe, UA-cam has for some reason decided not to send me updates for comments under just this one video.
Are you sure the animationtree is in the right place on the scenetree? Maybe you got a node in between? If you want this to get faster, hop onto the discord and post a screenshot
My animation tree is missing but its working, how to see it again, its like it became invisible
Won't be able to help you with this little info, join Discord and post more info
love the tutorial. Is there a way to get the animation lenght or the signal of a finished animation from animationtree?
The signal comes from your animationplayer, that has an animation finished build in signal. That still functions as normal.
Game Development Center thank you😍😍
great video, but please remove the video embed overlaid atop the editor... it's difficult to see what's going on, and doesn't provide helpful content
Can one make two animations run at the same time from the animation Tree?
For instance, using the Animation Tree to use a Run Animation and then if you press a key, you activate an item that makes fire cicle you or activates an animation that moves the character's arm from a diferent animation/sprite sheet and making the current one disappear meanwhile?
AnimationTree seems just fine for simple things, but slightly more complicated ones already make me super lost
That's because in 2d your limited. The animation is nothing more than a change if image, and not a movement of a limb as you would in 3d.
The fire circle should be possible, may be easier with a shader though.
@@GameDevelopmentCenter funny how I'm still stuck in this very same problem and I ended up in the same video. This is so frustrating.
I have the run cycle of my character running with his arm up and another run cycle of him running normally, but I can't make a seamless transition to the point I just feel like dropping Godot
Nice tut! Btw check how melee is pronounced, it's pretty weird
Hahah, yeah there is a word or two, maybe three or four that I have a hard time unlearning my pronounciation on. Thank you for the feedback!
Animeted tileset.... Like river or fire...
UA-cam has this quality content for animation trees and there a channel named Miziziziz who talks like a zombie, is getting 17k views
Haha, oww well, guess it is a good thing I compare myself to myself yesterday and not others :) Thx for your comment Anindya! Put a smile on my face :)
Sir Please can you add a Tutorial 2d racing game where vehicle move left right and background move left right, like old days, Please its a Request
Hi Santosh, thx for the suggestion! I will put it on the list, but it won't be anytime soon. I got a couple of series I want to work on first and we have new functions of Godot 4.0 to cover in the near future as well :) Hope you understand :)
@@GameDevelopmentCenter Thank you, Sir
