PhysicsObject¶

class PhysicsObject¶

Bases: TypedReferenceCount

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.__init__()¶

Default Constructor

copy constructor

PhysicsObject.add_impact()¶: 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.

PhysicsObject.add_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.

PhysicsObject.add_local_impact()¶: 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.

PhysicsObject.add_local_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.

PhysicsObject.add_local_torque()¶

Local instantanious forces

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.

PhysicsObject.add_torque()¶

Global instantanious forces

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.

PhysicsObject.assign()¶

PhysicsObject.get_active()¶: Process Flag Query

static PhysicsObject.get_class_type()¶

INLINE void set_center_of_mass(const LPoint3 &pos); use set_position.

Vector position assignment. This is also used as the center of mass.

Piecewise position assignment

PhysicsObject.set_rotation()¶: set rotation as a quaternion delta per second.

PhysicsObject.set_velocity()¶

Vector velocity assignment

Piecewise velocity assignment
