Character Location

Is there a way to change a condition IF a character is at a location (not a scene) ?

I know there is a IF CHARACTER IS ON SCENE , but I can't find the IF CHARACTER IS AT LOCATION
I want once my character walks to a location to change a condition. (when he walks over a stone , I need to change the condition so the animation of the stone being pressed down is played)

use action areas via the way system tab

you can create on character enters/leaves actions for it.

Yes, thank you. I just found it ^_^
