The Drop Zone Full trigger allows you to trigger an action when the drop zone object is full i.e. it cannot receive any more dropped objects. For example, when the drop zone is full you could show a score box describing the correct number of drops in the zone; move to another page; or update the TOTAL_SCORE variable.
Note:
An object set up as a drop zone can only use this option. Furthermore, this option will only be triggered when a drop zone object has reached the maximum number of objects dropped in it. In other words, this option will only be triggered if the Limit Number of dropped objects checkbox has been ticked in the drop zone object’s Drag and Drop tab in the Properties dialog.
Add the Drop Zone Full trigger to your Actions Organiser, as described in Creating and Editing Actions.
Click on the Actions tab in the Actions dialog to select an action or actions to add to the trigger.
Go to Choosing an Action to list all of the actions you can add to your trigger.
