Asked By | DanielJu |
I am trying to have different animations play depending on movement direction and speed. I have been trying to get this to work for a while now, but to no avail.
The Animation Tree Player does seem to work fine when in preview mode, but animation simply does not run in Play.
Animation Tree Player does seem to move between the different animations, but just does not play each of the animations after switching.
I have no idea what’s causing this.
Is my code missing something? I set the animation tree player as active and I made the code change the value of the BlendSpace2D, not accurately (just to test it for now).
The following is a video of the issue that I am experiencing.
Any help will be really appreciated. This is really frustrating me.
The code is visible if you download the video and play it. If you play it directly on google drive, it won’t be visible.
The code I have, the parts concerning the animation tree player is as follows:
onready var animationPlayer = $CharacterGraphic/AnimationPlayer
onready var animationTree = $AnimationTree
func _ready():
animationTree.active = true
func _physics_process(delta):
if is_on_floor():
velocity.x = move_toward(velocity.x,maxMovementSpeed*moveDirection.x,movementAcceleration)
velocity.z = move_toward(velocity.z,maxMovementSpeed*moveDirection.z,movementAcceleration)
var currentSpeed = velocity.length()
var max1Speed = currentSpeed/maxMovementSpeed
animationTree.set("parameters/BlendSpace2D/blend_position",Vector2(moveDirection.x,moveDirection.z))
print(animationTree.get("parameters/BlendSpace2D/blend_position"))

Thank you, your sarcasm is much appreciated.
Actually, the fact that I am soliciting help from strangers and keeping it as easy as possible is precisely why I uploaded a google video and kept it down to the 15 lines of code that had anything to do with the animation tree player or the animation player, so that these helpful strangers don’t have to go through hundreds of lines of code.
I was hoping that it is a very obvious oversight or problem with another setting in the UI, not in the code, that I, being an inexperienced developer that I am, simply overlooked, and that someone more experienced could spot right away with the video clip I uploaded, which, again, can be downloaded and played (or you can just click the gear (setting) icon and set the video quality to 1080p and you should be able to see the code as well)
Also, I kept it down to those lines of codes, because the animation plays just fine if I am just using animation player instead of animation tree player (e.g. “animationPlayer.play(“WalkForward”)” - this can be seen in the code in the video as well, but I commented out those lines in the demonstration). So I am thinking the issue must be from those lines of code or not because of the code at all.

My bad. I don’t understand why it isn’t giving you a better resolution. It is readable watching through google drive from my end (using a different browser)
If you still wouldn’t mind taking a look at it.
This is the code in “BaseCharacter” scene (I left out targeting related codes that have nothing to do with the animation or the character movement (at the moment)):

As I have previously said, the video demonstrates the character does seem to switch to different animations, just not playing them. As mentioned, the animations do play when played using AnimationPlayer methods, just not with AnimationTree Player.
Let me know if you would like any additional detail or if the images are not displaying properly.
One drive share folder containing the images and the video preview:

One Drive video preview appears to support better resolution, so please check it out if you don’t mind, thank you.
