System pick instance condition

Hello, how does those conditions works ? I need to check if there is an instance under mouse position, and i thought of making condition "pick overlapping point". I did it, but i have no idea how to check if such instance exist. I need to perform an action ONLY IF there is no instance found under given position.

Another question: if i pick some instances with systems condition, how can i determine which particular instance I am using in actions ? Lets say I have action "set text to instance.variable" - if i pick more then 1 instance - how does it work in such situation ?

Your first problem:

Mouse-> Cursor is over object

Second:

As far as I know it always picks the last created instance. It's always good to be precise when picking objects.

THANKS MAN !!! Mouse coursor over object is perfectly fine for this purpose

By the way documentation says something different of picking instances with mentioned condition:

"Pick overlapping point

Pick all instances of a given object type that are overlapping a point in the layout. The given X and Y position in the layout will be tested against the instance's collision polygons."

yes, it picks all instances. But when you try to get an instance variable, it uses the object with the highest UID.

Here is a quick example capx that might help...

(There are, no doubt, other ways to do this)
