Framerate independent acceleration

So I understand that, to get frame rate independent movement I have to multiply the base speed by (1000/delta). It works on values that represent speed, but when I try this with an acceleration variab[详细]

How to create a rotation based Impulse Vector (Cocos2d, Chipmunk, Spacemanager)

So im trying to create character with two jetpacks - either of which can be fired independently of one another to create an impulse offset from the center of gravity (Using Cocos2d, Chipmunk, and Spac[详细]

How to find time and speed using iPhone's accelorometer

Let me tell you my physics is very bad. I want to calculate time between two points. The situation here is - if an object is moved from say point x to point y with an acceleration which is not constan[详细]

Algorithm to control acceleration until a position is reached

I have a point that moves (in one dimension), and I need it to move smoothly. So I think that it\'s velocity has to be a continuous function and I need to control the acceleration and then calculate i[详细]
