Triggers

Triggers are what control anything you want to happen while the scenario is being played, from spawning starting base to calling waves of attacking enemies or giving players objectives. There are several types of triggers which activate off of different events, but they all share some attributes in common:

• Name - Name of the trigger. Required.
• Type - What type of trigger it is. See below. Required.
• Inactive - If this trigger is inactive, to activate use the ActivateTrigger option from another Trigger.
• OtherTrigger - Name of another trigger that must have fired before this one will activate. Use this to set multiple conditions on a trigger occurring.
• NotOtherTrigger - Inverse of OtherTrigger. If the other trigger has fired this trigger won’t fire. Us this to create branching options in your scenario.
