Only if you get your wallet out and buy the eXtends plugin. Does full pixel perfect collision, even on scaled or rotated sprites.

Boo!

Or, for the price of extends you could buy PlayBasic which has it built in


Hmm, I wonder what's coming in 2011?

Did you see the example?
the arrays are filled like this>>
000000011100000
000000111110000
022222111112220
000000111100000
where zero means no collision on that pixel.and any other number
represents an area.(which can also be named in arnam$(ob,na)).
EX:the size of the array is x100*y200.The object's first pixel is
at x23,y45.You check if another object (say a one pixel bullet) is b2IN (23-123)x and (45,245)y.if yes you refer to arrays position bulletx-23 bullety-45 .If you find zero no collision.If other you have collision.Its a bit heavy for the system , if you have to check between objects that exceed 50X50 size.

That's my problem too. I've been hoping by buying DBPro that I can circumvent this problem of inaccurate sprite collision (esp. when they are rotating). Well, DBPro actually HAS a vast manifoldness of advantages — but still, I have already decided to order the Enhancement Package. 'Hope that one can mend this problem.

Wherever you plan to go,
it's the next step you never know.
