The physics engine will only include basic sphere mechanics (although I still haven't figured out how to accomplish that elusive sphere checking yet) my question for topic is about is how to calculate the correct roty of a ball rotation using these variables=x,y,xprevious,yprevious. I have gotten the correct rotx of the rotation using: rotx+=(abs(x-xprevious)+abs(y-yprevious)) but I don't know much trigonometry so any help for finding the right equation for roty would be awesome! Also I prolly need to know the equation for rotz as well... |
