The direction of the thrust is normally along the longitudinal axis of the rocket through the rocket center of gravity. But on some rockets, the exhaust nozzle and the thrust direction can be rotated, or gimbaled. The rocket can then be maneuvered by using the torque about the center of gravity. The magnitude of the thrust can be determined by the general thrust equation.
There are three types of DI: Directional Influence, Tap/Smash DI, and Momentum Canceling. Directional Influence is when you aim for the direction you want to go when being launched. If you are launched vertically, tilt the control stick to the left or right. If launched horizontally, tilt the control stick to the upper left or the upper right, in the opposite direction you are launched.
