Static Public Member Functions | |
static TypeHandle | getClassType () |
A body on which physics will be applied.
If you're looking to add physical motion to your class, do NOT derive from this. Derive from Physical instead.
PhysicsObject | ( | ) |
Default Constructor.
PhysicsObject | ( | PhysicsObject const | copy | ) |
copy constructor
addImpact | ( | Point3 const | offset_from_center_of_mass, |
Vec3 const | impulse | ||
) |
Adds an impulse and/or torque (i.e.
an instantanious change in velocity) based on how well the offset and impulse align with the center of mass (aka position). If you wanted to immitate this function you could work out the impulse and torque and call add_impulse and add_torque respectively. offset and force are in global (or parent) coordinates.
addImpulse | ( | Vec3 const | impulse | ) |
Adds an impulse force (i.e.
an instantanious change in velocity). This is a quicker way to get the velocity, add a vector to it and set that value to be the new velocity.
addLocalImpact | ( | Point3 const | offset_from_center_of_mass, |
Vec3 const | impulse | ||
) |
Adds an impulse and/or torque (i.e.
an instantanious change in velocity) based on how well the offset and impulse align with the center of mass (aka position). If you wanted to immitate this function you could work out the impulse and torque and call add_impulse and add_torque respectively. offset and force are in local coordinates.
addLocalImpulse | ( | Vec3 const | impulse | ) |
Adds an impulse force (i.e.
an instantanious change in velocity). This is a quicker way to get the velocity, add a vector to it and set that value to be the new velocity.
addLocalTorque | ( | LRotationf const | torque | ) |
Adds an torque force (i.e.
an instantanious change in velocity). This is a quicker way to get the angular velocity, add a vector to it and set that value to be the new angular velocity.
addTorque | ( | LRotationf const | torque | ) |
Adds an torque force (i.e.
an instantanious change in velocity). This is a quicker way to get the angular velocity, add a vector to it and set that value to be the new angular velocity.
