Validity of Triggers
You can invalidate an edited Trigger so that the Trigger will not run. When you need to run the Trigger, you can reactivate it. Invalid Triggers do not affect the logic of a game and can be activated and called when needed.
Right-click a Trigger and select Disable Trigger to invalidate it. Click Enable to reactivate the Invalid Trigger.
You can set the validity of a statement in the Trigger, so that the disabled statement will be skipped no matter whether the statement is completed. Right-click a statement and select Disable Line of Trigger to disable it. Similarly, right-click on the statement and select Enable to enable the disabled statement.
