// Throw (move at a constant speed without keyframes) veloc = -10; //horizontal velocity (pixels per second) x = position0 + (time – inPoint) *veloc; y = position1; x,y Same as throw, but for rotation. In this video tutorial, I demonstrate an expression using the key object properties of time and value to make a shape layer meet with a text layer — no matter what changes are.
