Oh, that's good to know then!
I was trying to stop only the sprites that was overlapping on the same family and I have solved that problem with 2 events but forgot to save and minutes later I have NO idea how I made that.. God.. that's crazy =/
family is - units
and there is sprite1 and sprite2..
sprite1 have a variable player 1 and sprite2 is player 2.
If I make an event like units overlapping units, it will activate even if sprites from player1 is overlapping another sprites of the player 1.
But I want only to activate if its overlapping sprites from player 2.
I have added some more conditions to the event to make it work but now have no idea what I did and forgot to save..
