Code for interactive masks

By default, when you assign an object to be the mask of another object, that object (the mask) loses its interactivity. For example, a sprite with a click event associated with it will recieve those events when not a mask but will not be able to once it becomes a mask.

If you want an object acting as a mask to be interactive, assign its buttonMode property to be true.

ActionScript Code:

maskInstance.buttonMode = true;
