Syntax:

set refVar to this
set refVar to GetSelf

Example:

if this == GetActionRef

set MyQuest.targetRef to this

An alias for GetSelf. Returns the calling object itself as a reference. Useful for if statements, or for setting reference variables on other scripts.

Notes:

• When this function is called on a carriable object (such as a weapon or miscellaneous item), the reference returned only remains valid while the object remains in the gameworld.
• This function appears to be unreliable when called on the player.
• This function returns 0 when called on a Light.
