UE2:IncrementalTrigger

About

This trigger is similar to the Round Robin class but instead of triggering all of the events in its array when it itself is triggered, it will only fire the first event. When it is triggered again, it will fire the second. The third time it is triggered, it will fire the third, and so on and so fourth until the last event has been triggered.

Properties

Visible

name Targets[16] 

An array of names. These names will be used to trigger events.

Hidden

int iCurrentArray 

The position in the array of names.

bool bTriggered 

Set internally. True if this actor has been triggered.

bool bDisabled 

True when the trigger has triggered all events.

Methods

PostBeginPlay() 

Starts the timer.

Timer() 

Controls array event triggering;

Trigger(Actor Other, Pawn EventInstigator) 

Called when this actor has been triggered.
