2 Rich "Hi man - I know u love 2d and all and so do I so I tht u could help me, but any1 else's input is also VERY welcome 2
"
I'm in the process of making a 2d demo in DBPro - the first time I've tried to make an entire 2d project since using DB1 and I've come accross a problem.
I have one sprite - for my example a Sonic. This is saved as bitmaps, loaded as images and called sprite 1. The black around him is automatically removed, as I would hope
I have another sprite which is a basic small floor. This is saved as a bitmap, loaded as an image and called sprite 1000. Again, the black around the floor is automatically removed
However, when I test for collisions between them, it detects collision not between the visible area of the sprites, but with the whole sprite including the invisible black areas. (essentially as a small rectangle and a big rectangle, not as a sonic shape and a floor shape.
I'm sure this used to work in DB1? Is this a bug or is there another command or extension I should be using? Is it because DBP now treats sprites as 3D and is therefore giving them "box" collision?
Code below (Its very early, only 3 hrs work, don't laugh
)

Like I said this is in DBPro, patch 3.1
Any help as to why this doesn't work will be well appreciated - it seems a pretty bad thing to be wrong if it is a bug? Like I said I've never attempted this in Pro before, only in DB1
If this is a known problem, any idea on a date for fixing it? Or is it my code? Or my PC setup? Thanks guys
