Thread: Can't make this circle disapear!

I am trying to make it so when you shoot a circle it disapears but I can't seem to get it to work!
Most of what relates to the circle disapearing is at the bottom.
Can you find my mistake?

Thanks and please if you can help me!

What seems to be the problem?
Does nothing happen when you shoot?
Does it shoot but not detect collision?
Does it detect collision but not disappear?

You can shoot the circle but the circle doesn't disapear it just stays there

Is the collision detection working? Put a println or two in the code and try to see where things stop happening the way you expected.

I have done that and collision is working its just the circle wont go away

i guess you need to tell that circle not to paint itself.. on a side note - you have a line that says:

if (enemylhit=true) 
 // something..

that line will ALWAYS be true, since you need == for comparison, only 1 = is assignment..

Ohhh so i need == instead of = Ok thanks now all i mee to know is how to tell it to unpaint itself or something like that
