How do I destroy something caugth inbetween a loop of objects?

Hi,

So, I used this tutorial to make a snake character: scirra.com/tutorials/4789/chain-of-sprites-with-pin-behavior-multi-sprite-snakedragon

What I would like to do is add a second snake character (easy enough); when the body of one of the snakes make a full loop around the opposing head I would like said head to be destroyed.

I can't figure out how to destroy an object unless it collides with another.

Any help would be great!

Thanks

Hello, You can make invisible objects around the head and pin then to the snake and when all of those objects are in colision with the snake then destroy the head.
