Can't set an Area2D scene monitorable property as false via script

+1 vote

I'm trying to set the monitorable property of the instanced Area2D scene as false via script after the other Area2D enters it, but it's not working, it's always says it is true. The rest of the code works as expected.

What am I doing wrong here ?

I've tried:

self.monitorable = false

or

self.set_monitorable(false)

I tried this too printing the monitorable property every frame, and you can actually see what's happening in the system console:

True
True
Entered
ERROR: Function blocked during in/out signal. Use set_deferred("monitorable", true/false).
   At: scene/2d/area_2d.cpp:424
True
True

It's a bit unintuitive, but the reason monitorable cannot be changed from within the signal handler is because the area is currently doing the monitoring, that state cannot be changed until it's done doing it.
So you may want to do this instead:

set_deferred("monitorable", false)

maybe try to use 

call_deferred(set_monitorable(false))

otherwise I do not know what's wrong

Edit: Zylann's answer is better. Idk what is wrong with me, set_deferred is way better
