Socoder -> Blitz -> circle collision detection? |

This is the first time I've thought about using anything other that regular box detection, but I'm attempting to move a ball around the screen using analogue(ish) input and having it hit off things. but so fat I'm only checking the x and y collisions separately, eg if x<0 then x=0:xmotion=-xmotion. But I want something a little more useful, at the moment the ball can easily get 'spiked' on the corner of a block or something, which doesn't look too good when your rolling this ball around. can someone give me a clue how to do this? Thanks -=-=- Check out my excellent homepage!

if you get the distance from the centre of the circle then you can check for collisions by looking if anything is inside its radius. Heres a get distance function (sorry its in C, but the maths is the same) |

There was a topic on this already, and I'm pretty sure my code allows for this. Like Mike_G's suggestion above, It does this through finding the distance from the centre of the circle. |edit| Here is the link to the other topic. |edit| |
