Basic state Animation in Godot

I decided to do what I had done on PlayCanvas in the Godot Engine. I made a project and added the models from Kenney but realized that these were in the FBX format so I needed to convert them (edit: They also have GLB versions I just had FBX since that’s what I used for PlayCanvas), I went with using GLB models which were more in line with open source but, after watching this guide on using Scene Trees, I caame to the realization that the animations were not repeating I found this intereating tidbit which meant that I had to import the GLB into the scene, instance it then edit its AnimationPlayer (which is denied unless you do the Animation Player -> Animation -> Manage Animation -> Click Save on the Global animation -> Click on the Save icon -> Select Make Unique for the first item, it doesn’t appear to change anything but it works), the funny part was trying to hardcode it and failing since having an Animation Tree will always override your Animation Player meaning that no, animation.loop_mode = Animation.LOOP_LINEAR will not work.

Here’s the resulting Movement.gd:

extends Node3D

@onready var animation_tree = $AnimationTree

@export var SPEED : float = 0.1
var isRunning : bool = false

var z = 0
var x = 0

func _input(event):	
	if event.is_action_pressed('ui_up'):
		z = 1
	elif event.is_action_pressed('ui_down'):
		z = -1
	elif event.is_action_released('ui_up') or event.is_action_released('ui_down'):
		z = 0
		
	if event.is_action_pressed('ui_right'):
		x = -1
	elif event.is_action_pressed('ui_left'):
		x = 1
	elif event.is_action_released('ui_left') or event.is_action_released('ui_right'):
		x = 0

func _ready():
	pass
	
func _physics_process(delta):
	isRunning = false
	
	if x != 0 and z != 0:
		isRunning = true
		if z > 0:
			$Rig.rotation_degrees = Vector3(0, x * 45, 0)
		else:
			$Rig.rotation_degrees = Vector3(0, -x * (180+45), 0)
	elif x != 0:
		$Rig.rotation_degrees = Vector3(0, x * 90, 0)
		isRunning = true
	elif z > 0:
		$Rig.rotation_degrees = Vector3(0, 0, 0)
		isRunning = true
	elif z < 0:
		$Rig.rotation_degrees = Vector3(0, 180, 0)
		isRunning = true

	position += Vector3(x * SPEED, 0, z * SPEED)
	update_animation_tree(delta)

func update_animation_tree(delta):
	animation_tree['parameters/conditions/isIdle'] = !isRunning
	animation_tree['parameters/conditions/isRunning'] = isRunning

The performance is spectacular as is usual with Godot. No need to switch browsers.
