Correct Manner to Apply Forces

[TBurnett]

Where can I find a simple demonstration of applying forces to bodies? Seems like this topic should be included as a demo.

If you have a simple btRigidBody, you can use the method:

Code: Select all

void applyForce(const btVector3& force, const btVector3& rel_pos) 

This applies a central force and additionally applies a torque depending on what you set in relative position.

To apply a torque, you can use:

Code: Select all

void applyTorque(const btVector3& torque)

Torque can only be applied to the center of mass (that is how it is defined in physics, not a limitation of Bullet Physics).

What exactly do you need?
