Jayenkai	You Never Learned.. What thing have you never learned, but probably should have? For me.. Pixel-based collisions. I've avoided those for YEARS, and have used bounding-box or similar for hundreds of games, including some which really could've done with better. -=-=- ''Load, Next List!''

Pakz	I learned about pixel based collision back when I was learning to use visual basic. I discovered the bitblit function and it's masks which were used back than for drawing transparent pixels. These masks were I think white at the parts of pixels that were not to be drawn. There was a explanation on pixel based collision which showed you checked two sprite arrays against each other with a loop. When two none masked pixels in this loop were at the same location than a collision happens. I think for myself a lot of problems I have would be solved if I learned to debug in a proffesional manner. Make notes, make more testbeds for things I do not really understand.

spinal	Coding in general. I can google reasonably well sometimes though. -=-=- Check out my excellent homepage!

Jayenkai	@ Pakz. Yeah, the simple stuff's easy enough. But then you add rotation and scaling, and everything goes out the window! At some point, it's quicker to just box-collide! -=-=- ''Load, Next List!''

Pakz	Yeah, I had not thought of rotation and scaling Functions for rotating and scaling a array I have not seen anywhere yet. There is a cheap book I bought on 2d collision but I did not seen anything like that in there. It just said you combine multiple collision types ontop of your sprites so they look like they are pixel perfect.
