Hi In my pinball assignment, I used the sphere-plane collision detection method to detect the collision between pinball and flippers. However, I found that this method didn''t always work. Any other methods can suggest to me?? Thx!!! chikit

you said assignment, now i''m probably in a lower grade than you but assignments tend to be a 1 person job. Try to think of some other ways to make it work, if you want to get a job really programming you''ll have to figure stuff out on your own all the time and you can''t go to message boards for everything. Try to figure out a few more ways and then see if it works, if so go with that, if not ask for help then.
