projectile detection problem

[Understood]

Hi
I made a tank, and would like it to have its own HP. The problem is that I can't seem to figure out how to detect when a projectile hits the tank, and not the player. I've tried a few things but have had no luck so far.

Basically, I think I need onActionProjectile() to be called whenever a projectile hits a shape surrounding the player...not the player himself
