==Introduction==
#REDIRECT [[Trigger]]
Triggers are an essential function for mission designers. A trigger (sometimes called a sensor) allows a mission designer to control events within a mission. Some common uses for triggers are controlling the timing of squad moves, camera control in cutscene, or even play the appropriate music when the time is right.
 
==Activation==
 
There are several combinations that can be created to activate the trigger. The trigger can be used to check if [[east]] or [[west]] is ''present'', ''not present'', or even ''detected'' within the trigger. A trigger can also be used to set up ''radio'' commands.
 
If an activation is set to "repeatedly" the trigger first has to be 'deactivated' before it can fire again (e.g. if a unit activated the trigger by entering it, it will first have to leave it, before the trigger can become active again.)
 
==Countdown==
Defines (in seconds) how long to wait until '''On Activation''' is fired. Min, Max and Mid allow you to add some randomization to the time.
 
==Condition==
In addition to the 'Activation' options above, this field allows you to specify other conditions that have to be fulfilled before  the Trigger activates.<br>
By default only the [[Boolean|boolean]] variable '''this''' is present in this field. It is set to the result of the main 'Activation' condition (e.g. 'east'/'present').<br>
The expression in this field must return a [[Boolean|boolean]] value (e.g. "this && alive player").<br>
Trigger conditions are tested every .5 seconds.
 
==On Activation/Deactivation==
Defines action that is performed when trigger condition changes to [[true]] or [[false]]. Expression must either be an assignment or return [[Nothing|nothing]]. Variable denoting trigger can be created by filling in [[name]] field. Array variable '''thisList''' will contain a list of all vehicles that met the trigger condition (e.g. hint format ["%1 units in area",count thisList]).<br>
 
==Effects==
Allows the mission designer to add music, environmental sounds, or to display title messages.<br>
Many use the effects to create quick and easy cutscenes.
