Wait()-like function?!

Question

So, is there a built-in function to GDScript where I can pause a process in a script for a few seconds, say:

set_visible(false)
wait(1) #waits for 1 second
set_visible(true) #then continues the rest of the script after the 1 second wait

Answer 1

Try:

var t = Timer.new()
t.set_wait_time(3)
t.set_one_shot(true)
self.add_child(t)
t.start()
yield(t, "timeout")

Comments

Don't forget to free the timer afterwards, or you'll cause a memory leak.

t.queue_free()

Answer 2

See OS.delay_msec and OS.delay_usec.

Comments

Note that if you use those in the main thread, those will cause the project to freeze until the delay has expired.

Answer 3

yield(get_tree().create_timer(1.0), "timeout")

Comments

Does the timer created here get disposed?

I believe that, once the routine has been resumed, the SceneTreeTimer object, returned by the create_timer () function, becomes invalid, as documented at:
