name: roblox-physics description: Roblox physics and parts: BasePart, Model, constraints, welds, motors, collision. Use when working with 3D objects and physics.

Physics Reference

Adaptive timestepping: Adaptive timestepping automatically assigns physical parts to varying simulation timesteps.
Assemblies: Explains physical assemblies and how they behave in Robloxs rigid body physics engine.
Character controllers: Controller instances can be used as a component in a custom character implementation.
AlignOrientation: The AlignOrientation constraint applies torque to align two attachments, or to align one attachment with a goal orientation.
AlignPosition: The AlignPosition constraint applies force to move two attachments together, or to move one attachment to a goal position.
AngularVelocity: The AngularVelocity constraint applies torque on an assembly to maintain a constant angular velocity.
BallSocket: BallSocketConstraint forces its two attachments into the same position and allows them to freely rotate about all three axes, with optional limits to restrict both tilt and twist.
Cylindrical: CylindricalConstraint allows its attachments to slide along one axis and rotate about another axis, with optional assigned angular and/or linear power.
Hinge: HingeConstraint allows its two attachments to rotate about one axis, with optional assigned power for motor or servo behavior.
LineForce: The LineForce constraint applies force along the theoretical line connecting its two attachments.
