Adding a wait(Answered)

Ok, I am working on a state machine for an Action RPG enemy. I have three attacks. I want there to be a telegraph state where the player gets an audio warning before the enemy attacks. I have tried using a timer and using a yield both seem to make the attack cooldown wonky. Any suggestions would be appreciated.

This is my telegraph state:

	    TELEGRAPH:
			velocity = lerp(velocity, Vector2.ZERO, 0.1)
			var rng_attack = (rng.randi_range(16, 1) * press) - press
			var now = OS.get_ticks_msec()
			if now >= next_attack_time:
				sprite.self_modulate = Color("#2E2EFE")
				if rng_attack < 20 && attack1_cooldown.is_ready():
					$Sfx/Attack1.play(0.0)
					print("attack1"+' ', rng_attack, ' ', press, ' ', attack1_cooldown.time)
					which_attack = 1
					next_attack_time = now + attack_cooldown_time
					state = ATTACK
				if rng_attack > 20 && attack2_cooldown.is_ready():
					$Sfx/Attack2.play(0.0)
					print("attack2"+' ', rng_attack, ' ', press, ' ', attack2_cooldown.time)
					which_attack = 2
					next_attack_time = now + attack_cooldown_time
					state = ATTACK
				if rng_attack == 0 && attack3_cooldown.is_ready():
					$Sfx/Attack3.play(0.0)
					print("attack3"+' ', rng_attack, ' ', press, ' ', attack3_cooldown.time)
					which_attack = 3
					next_attack_time = now + attack_cooldown_time
					state = ATTACK

I believe a Timer would be the easiest way to do this. You'll have to add a callback function for when "timeout" happens, and then do the thing you want to do (change the state, etc.)

onready var timer = get_node("Timer")

func _ready():
	timer.connect("timeout", self, "switch_to_attack")
	
func switch_to_attack():
	state = ATTACK
    # do other stuff

And in your switching code, you can call:

timer.start()

And that will start the timer.

Thank you, sorry I didn't respond sooner, been a busy day. Still needs a little tweaking, but it works better than what I had =)

You may also just use delta.

var timeout: = 3.0

func _process(delta: float):
    if timeout > 0:
        timeout -= delta
        if timeout <= 0: on_timeout()

Then you know you can just reset timeout to anything you want.
