Bounding box collisions are easily doable in DesktopX.
But sometimes pixelbased collisions are useful for games - or other image-image interactions.
DesktopX has no way of doing this, except now with dxCanvas I can use the in memory rendering methods it exposes to rapidly do image composition.
dxCanvas also exposes a pixel array which lets you check every pixel in a range for a particular colour combination.
It's really a 'tech' demo - to show it can be done in DesktopX without it being too slow and useable.
There's an 'interactive demo' now called 'collisionDemo.exe' on my skyDrive - I just cobbled it together as quickly as possible to test some collision methods.
It also doesn't demo the pixel collision too well, sometimes the collision occurs before the 'draw' of the object and it looks like box collision is all that is at play.
Maybe you'd like to make a DesktopX game RND?
