My custom "wait" function doesn't work as intended.

NewbieToGameDev

I made a custom function to make my life easier with delays, it's called "wait(seconds)", but for some reason it doesn't work.

extends Control

func _ready():
	wait(2)
	$WindowDialog.popup()

func wait(seconds):
	yield(get_tree().create_timer(seconds), "timeout")

But yield works perfectly fine. Is there anything wrong in the code?

you are calling your wait() from _ready(), I don't think that makes much sense?

When you yield, your program returns to the previous function and continues executing. In this case, you're returning to _ready() and calling popup(). If you yield from ready(), you'll get the result you want.

You almost never want to use yield, or a fake wait function based on yield. The reasons are complex, but it doesn't work like you expect. Most likely what you want to do is create a Timer and then on the timeout signal callback you call some other function.

Oh I see my mistake lol, Thank you

I mean, yield with an anonymous Timer should be fine, because it is highly unlikely, or impossible, it will fail. But using yield with custom functions can create all sorts of strange issues if the function has a problem your game will hang or crash, or, even if it completes, you mess up the timing so you can't be 100% certain that things are executing in the correct order.
