Question

Hi, I’m trying to implement a state machine, and I can’t seem to get it to work. Here’s the tree:

statemachine
statemachine1086×237 15.5 KB

and here’s the relevant code:

func _ready():
	state_machine = anim_tree.get("parameters/playback")

func _process(delta):
	velocity = Vector3.ZERO
	#AI
	#IDLE
	#Idle Start
	if state == ST_IDLESTART:
		state_machine.travel("idle")
		timer_max = rng.randi_range(120,240)
		if timer < timer_max:
			timer += 1
		elif timer >= timer_max:
			turn_goal = rng.randi_range(1,180)
			#turn_dir = rng.randi_range(0,1)
			turn_dir = DIR_RIGHT
			state = ST_IDLETURN
	
	#Idle Turn
	elif state == ST_IDLETURN:
		#Find which direction to turn
		if turn_dir == DIR_RIGHT:
			state_machine.travel("turn_right_walk")
			if state_machine.get_current_node() == "turn_right_walk":
				rotation.y -= 0.01
				turn_num += 1
			if turn_num >= turn_goal:
				state_machine.travel("walk")
				state = ST_IDLEWALK

    #IdleWalk
    elif state == ST_IDLEWALK:
		global_transform.origin -= transform.basis.z.normalized() * SPEED * delta

The issue I’m having is that the enemy will reach the “Turn Right” Blend Tree, which is just the Turn Right animation slowed down by 0.5, and then won’t progress any further. But if I remove everything after “turn_right_walk”, then it gets to “turn_right_walk” no problem, which seems weird as the travel function sending the enemy to “turn_right_walk” isn’t changed at all between the two iterations.

Any help is greatly appreciated. Thanks!
