How to Use the Triggers in the SC2 Map Editor

"StarCraft II," also commonly referred to as "SC2" is a Real Time Strategy game developed by Blizzard Entertainment. Players can play through a singleplayer campaign, compete against one-another in online battles through Blizzard's "Battle.net" service and even create their own content. "SC2" comes with a map editor program wherein you can create custom maps, and create custom events, also called "Triggers" on these maps. Use these "Triggers" to define what needs to happen to set the trigger off as well as what happens when a trigger is set off.

If you know the type of action, you can also type it into the search field. Depending on the type of action, you may then have to set further conditions and values in the selections under the "Actions" heading. For example, you might select a "If Then Else" type of action. You must then set conditions under "If," "Then" and "Else" under actions.
