The Drop Refused trigger allows you to trigger an action when a drag object is dropped into the wrong drop zone object. For example, you can use this trigger to deduct points from a score total variable when the object is dropped in the wrong drop zone.
Note:
This option can be used by any drop zone object. However, this option will only be triggered when you have selected the These selected objects only option in the drop zone object’s Drag and Drop tab in the Properties dialog. Any drag object you have NOT selected in the These selected objects only list will activate this trigger.
Add the Drop Refused 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.
