I tried that pick top/bottom conditio, but it doesnt work...
I made simply test with 2 objects:
1. Event: Condition: left click on Object_A > Object_A move to top
2. Event: Condition: left click on Object_B > Object_B move to top
So i can choose which object is on top by clicking one of them.
And event like this:
Condition: Object_A pick top instance > set Object_A.Y + 1
So Object_A should keep moving while it's on the top on the layer. But it's moving down to the screen even if its at the bottom ;/ so it doesn't work correctly..
