Wait until Animation is finished?

Question

I have a script wich plays multible animations after each other, but if I execute it, it plays every animation at once. (Note that the animation sequence is changing everytime it executes)
How can i wait until the animation is finished and then call the next animation?

Thanks for help,

Answer 1

Connect the AnimationPlayer's "finished" signal to a function, that starts the next animation!
For example:

onready var player = get_node("AnimationPlayer")

func _ready():
    player.connect("finished", self, "playNextAnim")
    player.play("anim_1");

func playNextAnim():
    if(player.get_current_animation() == "anim_1"):
        player.play("anim_2")

Brilliantly simple. Nice

In Godot 3.3 , the callback is "animationfinished", and passes in a parameter 'animname'... i had to pass that into the playNextAnim above, as my 'player.getcurrentanimation() would return an empty string on finished'

Answer 2

Somewhere In the official docs, there's your answer in the yield function:

yield( get_node("AnimationPlayer"), "finished" )

For your example, it'll look like :

onready var player = get_node("AnimationPlayer")

func do_my_animation_sequence:
    player.play("anim_1")
    yield( player, "finished" )
    player.play("anim_2")
    yield( player, "finished" )
    player.play("anim_3")
    ...

I found that the line below cannot work now:

yield(get_node("AnimationPlayer"), "finished")

But this code works:

yield(get_node("AnimationPlayer"), "animation_finished")

I test in Godot 3.0.6.

That is because in Godot 3, the "finished" signal has been changed to "animationfinished".
So "finished" should work for Godot 2 and "animationfinished" for Godot 3

Cool, now have a hitting animation! Thanks!

Best answer IMHO, use animation_finished for godot 3.0 upwards

Answer 3

You can create a function to lock the animation and call it from the animation track.

var animation_is_active = false

func _process(delta):
    if Input.is_action_just_pressed("ui_attack") and not animation_is_active: 
        animation_player("attack")

# Method called in first key (true) and last key (false) of the animation track
func activate_animation(state): 
    animation_is_active = state

Comments

It's better to use animation_finished() signal.

You are right, but sometimes we only need to get that in one situation, the signal is better, but if you want to play the same animation multiple times, and after each do something different, the yield(get_node("AnimationPlayer"), "animation_finished") is better
