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.

Inheritance diagram

__init__() → None¶: Default Constructor

__init__(copy: PhysicsObject) → None: copy constructor

assign(other: PhysicsObject) → PhysicsObject¶

Return type: PhysicsObject

setActive(flag: bool) → None¶: Process Flag assignment

getActive() → bool¶: Process Flag Query

setMass(param0: float) → None¶: Set the mass in slugs (or kilograms).

getMass() → float¶: Get the mass in slugs (or kilograms).

setPosition(pos: LPoint3) → None¶: Vector position assignment. This is also used as the center of mass.

setPosition(x: float, y: float, z: float) → None: Piecewise position assignment

getPosition() → LPoint3¶

Position Query

Return type: LPoint3

resetPosition(pos: LPoint3) → None¶: use this to place an object in a completely new position, that has nothing to do with its last position.

setLastPosition(pos: LPoint3) → None¶: Last position assignment

getLastPosition() → LPoint3¶

Get the position of the physics object at the start of the most recent do_physics.

Return type: LPoint3

setVelocity(vel: LVector3) → None¶: Vector velocity assignment

setVelocity(x: float, y: float, z: float) → None: Piecewise velocity assignment

getVelocity() → LVector3¶

Velocity Query per second

Return type: LVector3

getImplicitVelocity() → LVector3¶

Velocity Query over the last dt

Return type: LVector3

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.

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.

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.

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.

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.

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.

setTerminalVelocity(tv: float) → None¶: tv assignment

getTerminalVelocity() → float¶: tv query

setOriented(flag: bool) → None¶: Set flag to determine whether this object should do any rotation or orientation calculations. Optimization.

getOriented() → bool¶: See setOriented().

setOrientation(orientation: LOrientation) → None¶

getOrientation() → LOrientation¶

get current orientation.

Return type: LOrientation

resetOrientation(orientation: LOrientation) → None¶: set the orientation while clearing the rotation velocity.

setRotation(rotation: LRotation) → None¶: set rotation as a quaternion delta per second.

getRotation() → LRotation¶

get rotation per second.

Return type: LRotation

getInertialTensor() → LMatrix4¶

returns a transform matrix that represents the object’s willingness to be forced.

Return type: LMatrix4

getLcs() → LMatrix4¶

returns a transform matrix to this object’s local coordinate system.

Return type: LMatrix4

makeCopy() → PhysicsObject¶

dynamic copy.

Return type: PhysicsObject

setName(name: str) → None¶

getName() → str¶

output(out: ostream) → None¶: Write a string representation of this instance to <out>.

write(out: ostream, indent: int) → None¶: Write a string representation of this instance to <out>.

static getClassType() → TypeHandle¶

Return type: TypeHandle
