Thanks for the good feedback, i havn't worked on this for a week or 2, so I'm trying to catch up with where i was now.
I've altered the Explosion Function so it creates an animated sprite of an explosion, so now health deductions are calculated by amount of time there is collision with the explosion sprite and the worm, this way damage is automatically calculated, and the bigger the explosion, the higher the frame number on the explosion will go to, IE, A ShotGun will only allow up to Explosion Frame 5, Where as the Bazuka allows up to the max of Frame 20 as in Picture below.
