PhysicsObject

from acron.physics import PhysicsObject

class PhysicsObject

Bases:

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.

Default Constructor

copy constructor

property _default_terminal_velocity → ConfigVariableDouble

getter for static ConfigVariableDouble PhysicsObject::_default_terminal_velocity;

property active → bool

Process Flag Query assignment

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.

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.

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.

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.

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.

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.
