Get only the first instance clicked

[Keith]

I have 10 instances of the same object stacked on top of each other. I want an event to only be fired for the first one I click on (topmost) so I can invert it. I have tried Only one action when event loops without any luck along with my User clicks with left button on Active. Any solution?

+User clicks on active
+only one action per event loops

this should choose only one object.

I have use this numerous times and it has always worked for me.

lol ProdigyX he just stated he tried the only one action when event loops method.

I think I've dealt with objects overlapping before and my solution was to run a ForEach loop through the objects, then I have a temporary variable that is set to -1. If the object's spread value is greater than the variable, then I set the variable to that object's spread value. What this essentially does is it keeps changing that temp variable until it is the highest value for that group of objects.

After that, you can do a condition when you click on the object, you also check to see if that object's spread value is equal to the temporary value. Meaning it is the topmost object in the stack. This will ensure that you select the top most object every time.

If anyone has a simpler way, please feel free to share.

The Select Object extension could do this in one line, but it's not compatible with all exporters.
Otherwise, you can say:

+ Always
-> Active: Set value to 0

+ Mouse is over Active
+ Player clicks
-> Active: Spread value 1

+ Mouse is over Active
+ Player clicks
+ Value of Active = 1
-> Active: Do whatever...

That works because by default, the order in which objects are layered, is the same as the order in which values are spread (based on the order in which they were created). If you manually change the layering order, using "bring to front" / "send to back" etc, it won't work any more.
