Position

The Constraint->Position command in the Actor and Motion modules constrains the centre of one or more selected objects to the centre of another object or to a null.

For more information about animating using constraints, see the Constraints section of the Animating User's Guide.

Note:

Position is the only constraint that can be applied to lights.

Procedure

1. Select the objects to be constrained.
2. Choose the Constraint->Position command.
3. Pick the object that is to act as a constraint.

The constraining object flashes red. The constrained objects reposition their centres to the centre of the constraining object. When a transformation is performed on the constraining object, the constrained objects' centres remain aligned.

Note:

You can constrain one object to many objects. In this case, the average position is computed.

You can completely deactivate and reactivate an individual constraint using the DopeSheet.

You can mix path animation, explicit animation, and constraints for a single object by deactivating segments of animation and/or a constraint in time using the Dopesheet. This allows you to do something like this:

1. Constrain a ball in the hand of character A from frame 0 to 20.
2. Make it follow a path up to frame 40 (the ball is being thrown).
3. Constrain the ball to the hand of character B.
