I'm trying to implement a basic user controlled sliding box with pygame. I have everything worked out, except for two things.
The acceleration is changed once a second (for meters/second) this leads to very jumpy movement. I need to add a way to check how long it takes the program to loop and multiply the acceleration by that much. (I think) After I move, the box slows down appropriately, but then the speed passes 0 and the box shoots off the other way. The equation (in real life) is mS (Coefficient of static friction)*Normal Force >= friction force. So lets say I am slowing down at a rate of -2m/s^2, if I hit 1, the next number will be -1 and I shoot off in the other direction. How do I fix this an still have backwards movement? -- http://mail.python.org/mailman/listinfo/python-list
