currently working on the code for my collision detection. these are the 4 most popular methods to detecting collisions. ill probably end up using bounds as it works for all object types. distance is calculated with coodinates as does contains a point but its not suitable for all my objects and bitmap comparision will take too much time to code. if i was in a job and time was short id have to learn the best and fastest way to code this so i think bounds is best.
