Description

An AnimationConstraint constrains its Attachments so that they're offset by Transform.

IsKinematic

TypeDefault
boolfalse

When true, the connected parts follow the Transform perfectly without participating in physics simulation. When false, the connected parts follow the trajectory using forces and torques limited by MaxForce and MaxTorque.

MaxForce

TypeDefault
float10000

Maximum force magnitude the constraint can apply to achieve its goal. Only used if IsKinematic is false.

History 2

MaxTorque

TypeDefault
float10000

Maximum torque the constraint can use to reach its goal. Only used if IsKinematic is false.

Transform

TypeDefault
CFrame0, 0, 0, 1, 0, 0, 0, 1, 0, 0, 0, 1

The internal CFrame that is manipulated when the constraint is being animated.

Note that AnimationConstraint transforms are not applied immediately, but rather as a batch in a parallel job after RunService.PreSimulation, immediately before physics steps. The deferred batch update is much more efficient than many immediate updates. If the AnimationConstraint is part of an animated model with an Animator, then Transform is usually overwritten every frame by the Animator after RunService.PreAnimation and before RunService.PreSimulation.
