Magic variables are engine-maintained variables that serve a specific purpose within a given scope and are often used by the engine to push data to a given script or code fragment.
They are usually no longer present after leaving the scope (e.g. after code execution or after a forEach statement).

Variable	Description	Data Types	Used In	Introduced With
thisTrigger	Refers to the trigger object itself - accessible within the Condition, On Activation or On Deactivation script.	Object	Triggers	-
thisList	"Variable defined by Triggers and Waypoints: Triggers: accessible within the Condition, On Activation or On Deactivation script defines an array of objects that have been detected by the trigger (same as what is returned by the list command) thisList in a trigger's On Deactivation field seems to be undefined, and should not be used. It will either return an empty array, or possibly the contents of a different trigger. Waypoints: accessible within the Condition or On Activation script defines an array containing all group members that completed the respective waypoint"	Array of Objects	Triggers & Waypoints	-
this	In Addons' config files (e.g. UserActions, onInit, etc.): The object to which the entry belongs In Dialogs: The player unit that activated control (e.g. via mouseEnter). false if non-activated In Object's ""Init"" line: The object to which the init line belongs In Triggers ""Condition"" line: The Boolean return value of the trigger's conditions (e.g. ""East Not Present"" etc) ""On Activation/Deactivation"" line: Seems to always return false In Waypoints ""Condition"" or ""On Activation/Deactivation"" line: The group leader that completed the respective waypoint (or driver, if waypoint is assigned to a vehicle)"	See description.
