Director allows you to lock a sprite, preventing any of its properties from being changed inadvertently. This feature can be particularly useful when you don't want to accidentally move or delete a carefully positioned sprite on the Stage. Locked sprites remain visible on the Stage but can't be selected from the Stage.
The locked sprites are displayed with a lock symbol in the Score ( Figure 3.75 ). When selected in the Score, a locked sprite is surrounded by a red border on the Stage, which includes a lock symbol in the top-right corner ( Figure 3.76 ). Property fields are dimmed for locked sprites in both the Property Inspector and the Sprite toolbar.
