To keep it short, I've been messing around with the free version, making extremely simple games just to see how I like the program. In my current game I'm working on, I'm trying to make it so that when all entities of a specific sprite are gone, the player get's a game over popup. I've noticed there is a 'see if on screen' condition, so I tried to use that for the sprite that the player goes around and destroys. I inverted the 'see if on screen' but it seems to do nothing different, and I can't seem to find a way to make this work. So I suppose my question would be, how can I make it so once all entities of a certain sprite are destroyed, a condition is fulfilled making another action occur? Also, what exactly does the 'invert condition' do? I was under the assumption it would be the same as a 'not statement', but that doesn't seem to be the case.
