# Legacy:Counter

### From Unreal Wiki, The Unreal Engine Documentation Site

UT :: Actor (UT) >> Triggers (UT) >> Counter (Package: Engine)
UT2003 :: Actor >> Triggers (UT2003) >> Counter (Package: Gameplay)

Note: In UT200x, you should use a ScriptedTrigger with ScriptedActions instead.

A counter will need to be triggered n times before it will trigger an event.

Examples of using a counter:

- several buttons must be pressed before a door opens
- a monster appears once a player has picked up a particular number of items in a room
- the secret door in UT's DM-Codex

Because the Counter simply counts how many times it's been triggered, the order in which things trigger it has no relevance – there's no way for the Counter to know. In particular, if the Triggers are set as repeatable, the same Trigger n times will also do it (the door in DM-Codex can be opened by shooting just one light four times).

To avoid this, set Triggers to non-repeatable or with a long delay For something where the order matters, use a CodeMaster system.

## Properties

### Main

byte NumToCount
  Number to count down from.
bool bShowMessage
  Will show CountMessage.
string CountMessage (localized)
  What message needs to be showed each time its triggered. For example: "Only %i more to go..."
string CompleteMessage (localized)
  What message needs to be showed when the count is completed. For example: "Completed!"

### Hidden

byte OriginalNum
  Number to count at startup time.

## Functions

BeginPlay()
  Init for play. Sets `OriginalNum = NumToCount`.
Reset()
  Reset actor to initial state - used when restarting level without reloading. Sets `NumToCount = OriginalNum`.
Trigger( Actor Other, Pawn EventInstigator )
  Counter was triggered. If NumToCount is more than zero, decrements NumToCount. If NumToCount is zero, Triggers all matching actors. Else, if bShowMessage, displays ClientMessage of CountMessage and replaces %i with "one", "two", etc. up to "six". (More than that, it will display the string equivalent of NumToCount. i.e., "7".)
