Properties

Property: Function:
Activate After you resize the constrained GameObject and its source GameObjects, click Activate to save this information. Activate saves the current offset from the source GameObjects in Scale At Rest and Scale Offset then checks Is Active and Lock.
Zero Sets the rotation of the constrained GameObject to the source GameObjects. Zero resets the Scale At Rest and Scale Offset fields then checks Is Active and Lock.
Is Active Toggles whether or not to evaluate the Constraint. To also apply the Constraint, make sure Lock is checked.
Weight The strength of the Constraint. A weight of 1 causes the Constraint to resize this GameObject at the same rate as its source GameObjects. A weight of 0 removes the effect of the Constraint completely. This weight affects all source GameObjects. Each GameObject in the Sources list also has a weight.
Constraint Settings  
Lock Toggle to let the Constraint resize the GameObject. Uncheck this property to edit the scale of this GameObject. You can also edit the Scale At Rest and Scale Offset properties. If Is Active is checked, the Constraint updates the Scale At Rest or Scale Offset properties for you as you resize the GameObject or its Source GameObjects. When you are satisfied with your changes, check Lock to let the Constraint to control this GameObject. This property has no effect in Play Mode.
Scale At Rest The X, Y, and Z values to use when Weight is 0 or when the corresponding Freeze Scale Axes is not checked. To edit these fields, uncheck Lock.
Scale Offset The X, Y, and Z offset from the transform that is imposed by the Constraint. To edit these fields, uncheck Lock.
Freeze Scale Axes Check X, Y, or Z to allow the Constraint to control the corresponding axes. Uncheck an axis to stop the Constraint from controlling it. This allows you to edit, animate, or script the unfrozen axis.
Sources The list of GameObjects that constrain this GameObject. Each source has a weight from 0 to 1.
