I think I need some examples for game logic.
If I press a key one time something should appear in the scene, and if I press the same key a second time it should disappear again. Pressing a third time should start again, as if pressing the first time.
It would be nice, if this works with the edit object-actuator as well.
I learned already to achive appearing and disappearing, if using two different keys, and I too know, how to use the visibility-actuator in a way, which shows objects just as long as I press one key.
Are there some examples out there, through which I could study some advance key-logic for logic-bricks?
