# Dezro/99 Bottles

## Sing 99 Bottles of Beer

And this is the last place I'm putting this thing. I swear.

Inspired by http://99-bottles-of-beer.ls-la.net/

    // 99 Bottles of Beer, in UnrealScript. Sings to every player
    // simultaneously. Written for UT2003, but would work on other Unreal
    // Engine games with little to no modification.
    // Probably works on a network. I haven't checked.

## Comments

Wormbo: Nice. Actually you could optimize and localize it with LocalMessages, since the song also exists in other languages.

Tarquin: Submit it to http://99-bottles-of-beer.ls-la.net/ ! Can you have arrays of strings? Might be neater than using the "switch" statement.

Dezro: I've already submitted it. I didn't use LocalMessages, since I wanted to keep it down to one file. I didn't use string arrays, because I didn't think of it. I should have... I could have added some customization if I went that route, too, which would make up for the lack of localization a bit. Ah, well.

Ike Bart: I tried to compile it in UnrealEd 2 and I got an error on line 29. It said: Error in MutBottlesBeer, Line 29: Unrecognized type 'Controller.' Since I'm an absolute newbie at Unreal script for Unreal Tournament, I'd like to know what to do to make it compatible with Unreal Tournament.

Dezro: That's the "little modification" I was talking about. UT1 doesn't use the pawn/controller setup, so you'd have to change some things. Make the following changes to the code:

Wherever you find this | Replace it with this
local Controller C; | local Pawn P;
for (C = Level.ControllerList; C != None; C = C.NextController) | for (P = Level.PawnList; P != None; P = P.NextPawn)
C.Pawn.ClientMessage | P.ClientMessage

Ike Bart: After making those changes, I get an error message at line 84. It said: Error in MutBottlesBeer, Line 84: Unexpected 'defaultproperties'

Dezro: That's a different problem. You're not supposed to use UnrealEd when coding. If you stll want to, remove the "var int StartingBottles;" line, replace every other instance of "StartingBottles" with 99, and delete the "defaultproperties" block. It'll compile after that, probably.

Ike Bart: Thanks for the suggestion, Dezro. I got UnrealEd to compile the script after following your suggestions. Now I have to test it out in Unreal Tournament. I hope I made the .ini file for it correctly.

Ike Bart: I tested it out in Unreal Tournament and it works. It took around nine minutes to finish off all 99 bottles of beer.
