missile0 and playfield interaction

[dadecoza]

Hi Guys!

 

I'm a bit of a n00b and require a little help.

 

if collision(playfield, missile0) then pfpixel x y off : missile0y = 0 : score = score + 10

 

I want to hide the pfpixel where the missile hit how do I calculate x and y if I only have the coordinates of the missile?

 

or are there a nice elegant solution?

 

Thanks!

Found one of Random Terrains examples ...

x = (missile0x-18)/4 : y = (missile0y)/8
if collision(playfield,missile0) then pfpixel x y off : missile0y = 0 : score = score + 10

 

I should have figured that out by myself.
