HOW TO MAKE A MULTI-HIT ENEMY
First make a thin, invisible object. Like a clear pannel. Now set the sensor layer that you want for it. Now copy it as may times as you want, (1 per hit) and arrange them next to each other untill you have a square shape. (note) you can select and copy all the objects and make a complete new layer for more damage if you want. just drop them right on top of the first "Damage Cube" you made.
Now make your enemy graphic and turn off all sensor layers. Select the last pannel in your "Damage Cube" and connect it to your enemy (pannel first). Set your enemy to be removed on sensor. Make sure you've set your pannels to be removed on sensor as well!!! Now drop you enemy on top of your "Damage Cube" and your ready.
This is only a one sided damage model. You could also take your last sensor and put a "cap" on it to protect it or you could place it in the middle of the "Damage Cube" and make it a two sided design.
