class BulletRigidBodyNode¶

Bases: BulletBodyNode

Inheritance diagram

__init__(name: str) → None¶

setMass(mass: float) → None¶: Sets the mass of a rigid body. This also modifies the inertia, which is automatically computed from the shape of the body. Setting a value of zero for mass will make the body static. A value of zero can be considered an infinite mass.

getMass() → float¶: Returns the total mass of a rigid body. A value of zero means that the body is staic, i.e. has an infinite mass.

getInvMass() → float¶: Returns the inverse mass of a rigid body.

setInertia(inertia: LVecBase3) → None¶: Sets the inertia of a rigid body. Inertia is given as a three-component vector. A component value of zero means infinite inertia along this direction. Setting the intertia will override the value which is automatically calculated from the rigid bodies shape. However, it is possible that automatic calculation of intertia is trigger after calling this method, and thus overwriting the explicitly set value again. This happens when: (a) the mass is set after the inertia. (b) a shape is added or removed from the body. (c) the scale of the body changed.

getInertia() → LVector3¶

Returns the inertia of the rigid body. Inertia is given as a three component vector. A component value of zero means infinite inertia along this direction.

setGravity(gravity: LVector3) → None¶: Gravity

getGravity() → LVector3¶

Return type: LVector3

getLinearFactor() → LVector3¶

Restrict movement

Return type: LVector3

getAngularFactor() → LVector3¶

Return type: LVector3

setLinearFactor(factor: LVector3) → None¶

setAngularFactor(factor: LVector3) → None¶

pickDirtyFlag() → bool¶: Returns TRUE if the transform of the rigid body has changed at least once since the last call to this method.

static getClassType() → TypeHandle¶

Return type: TypeHandle

property mass¶

Getter

Returns the total mass of a rigid body. A value of zero means that the body is staic, i.e. has an infinite mass.

Setter

Mass & inertia

Sets the mass of a rigid body. This also modifies the inertia, which is automatically computed from the shape of the body. Setting a value of zero for mass will make the body static. A value of zero can be considered an infinite mass.

Return type: float

property inv_mass¶

Returns the inverse mass of a rigid body.

Return type: float

property inertia¶

Getter: Returns the inertia of the rigid body. Inertia is given as a three component vector. A component value of zero means infinite inertia along this direction.
