yield(get_tree(),"idle_frame") doubles the execution!

Question

hello,
I tried yield(get_tree(),"idle_frame") in _ready() function and it seems to work fine: when yield execute, it resumes execution just the line after and process goes smoothy.

but

I tried yield(get_tree(),"idle_frame") in a throwaway function called in _process(delta) and it doesn't work like that: each line of code between "yield" and end of function get executed twice.

Did it work as intended or is it a bug?

I'm using Godot 3.1 beta9

thanks
Graziano

Cannot reproduce this in beta 9 on my machine. Can you share the code? Or try to print something

I found out:
using yield() in _process() is troublesome because the script turn into a wait state, but application is still going to execute _process() the next frame time even if the wait state is still active.

I had only to build a bounduary around yielding function:

                 if !yielding:
                    yielding = true
                    some ()
                    yield(get_tree(),"idle_frame")
                    yielding = false
