# panda3d.physics.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.

__init__() → None

Default Constructor

__init__(copy: PhysicsObject) → None

copy constructor

addImpact(offset_from_center_of_mass: LPoint3, impulse: LVector3) → None

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(impulse: LVector3) → None

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(offset_from_center_of_mass: LPoint3, impulse: LVector3) → None

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(impulse: LVector3) → None

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(torque: LRotation) → None

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(torque: LRotation) → None

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.
