You can share anything you like. I had plenty, so I've already started a couple that have some partial code on Subversion, haha.

That's unfair Luke must have pieces of code for the next 2000 Mutator Week :p
Surprise ? Hmm let's see what can I find :thumbsdownsmiley:

Haha, I only wrote a few snippets, and only a few hours ago :thumbsdownsmiley:

I'll try and get them done tommorow, but I always have trouble finding time.

Hi All, I found some hours this sunday evening to release something.
The mutator is quite simple, It consists in reinitialising randomly all WeaponPickup and ammopickup. The purpose was to use new feature of UT3 such as interface.

Here is the code.

someone can tell me:
- is there a way to get weapon list such as Class'CacheManager'.static.getWeaponlist in UT2004
- How can i set a friendly name and a description to the mutator as i didn't see anymore these fields

Any comment is appreciated :popcorn:

Take a look at the weapon replacement mutator, that should go through all the weapons. Friendly name and description are generally set in the ini config file, although you can still enter the same fields into the mutator class itself, I believe. I'm not sure what the interface is for?

Yeah I already check this mutator it uses "Game.DefaultInventory". I didn't test yet but I 'm pretty sure this weapon list is non exhaustive.
Thanks for the IniFile suggest, I never touch config file stuff in UT3 for now.

I admit interface is quite useless in this case as there is only one implementation :popcorn: but you were talking about "experimental and cool code" so I try :popcorn:

It was just a Sunday Test Evening, I'll try to release something else for next weekend

Game.DefaultInventory is what the players start with in that game mode (the "default weapons") - it's not what you're looking for. In the check replacement function however, it uses this sort of thing:
NewAmmoClass = class<UTAmmoPickupFactory>(DynamicLoadObject(AmmoToReplace[Index].NewClassPath, class'Class'));

This is read in from a config variable - notably, the WeaponReplacement mutator has all the weapons chosen by a configuration scene - so it also has a menu class. Look in the menu class, and you'll find how this list is generated. You could then write an algorithm that randomly generates these lists instead of having them controlled by a configuration scene :popcorn:

thanks, I'll check that tonight

I have extra questions on UIScene.

In UT2004, you can open a menu with the methode ClientOpenMenu (or somethig like this) in PlayerController

I didn't find this in UT3, I found OpenScene in Engine.UISceneClient (not sure if it is the right direction) The question is where is the instance of this class ? I precise that I'm at work so I only use Uncodex to search :popcorn:

My advice is to stop looking at and referring UT2004 code. A lot of UT3 has changed - the UI system is completely different. OpenScene is the correct function - but UIScenes are editor objects. If you followed my second tutorial, you'd see a mutator config example :popcorn:

Edit: Here's the first one I'm working on, and easy one to make sure I have something by Sunday:

class LP_Mutator_Disguise extends UTMutator;

var StaticMesh playerBox, playerBoxRed, playerBoxBlue;
var() Vector BoxScale;

function ModifyPlayer(Pawn Other)
{
	local StaticMeshComponent BoxAttachment;
	
	if (Other.IsA('UTPawn'))
	{
			BoxAttachment = new(self) class'StaticMeshComponent';
			
			if (WorldInfo.Game.bTeamGame == true)
			{
				if (UTPawn(Other).Controller.PlayerReplicationInfo.Team.TeamIndex == 0)
				{
					BoxAttachment.SetStaticMesh( playerBoxRed );
				}
				else if (UTPawn(Other).Controller.PlayerReplicationInfo.Team.TeamIndex == 1)
				{
					BoxAttachment.SetStaticMesh( playerBoxBlue );
				}
			}
			else
			{
				BoxAttachment.SetStaticMesh( playerBox );
			}
			
			UTPawn(Other).AttachComponent(BoxAttachment);
			
			BoxAttachment.SetScale3D(boxScale);
	}
	
	super.ModifyPlayer(Other);
}

DefaultProperties
{
	playerBox = StaticMesh'LP_Disguise_Assets.Box'
	playerBoxRed = StaticMesh'LP_Disguise_Assets.Box_Red'
	playerBoxBlue = StaticMesh'LP_Disguise_Assets.Box_Blue'
	boxScale=(X=1.000000,Y=1.000000,Z=1.000000)
}

Should be real easy - attach a static mesh component to the player, so he's disguised as a box. Play in maps full of said boxes, and things get interesting. Mesh isn't showing in game however, and no logged errors. Doh.

Ahah interesting ^^. You should add a pic .

I take a look at UIScene and manage to open one when I want ("Open Scene" remember ? :dry:) I may release an extra mutator :xcahik_:

I have an extra question about UIScene: Is there a way to use Timer in those classes? as they don't inherit from Actor

I believe the UTUIWidgets have internal tick functions. This is very similar - it depends what you want to do though. If you want proper timing functions, you'd need to tie the scene to Kismet, which is nasty.

I want to display a countdown and update a label text each timer period

setTImer(1, true);

function Timer()
{
  if( counter > -1)
	updateLabel(counter --);

  else
  {
	settimer(0, false);
	closeScene(self)
  }
}
Something like this in fact.

Indeed I can use AnimTick() to simulate timer.

I may change to an Action to close Scene

My idea is something like the vampire mod for ut2k4 (when you hit someone, you steal his health). The difference is that I want to give the stolen health to a randomly choosen player (but the one who's hurt).
After hours of digging the script reference, I still can't override the function that takes health from one player and make it give the health to another.
Last attempt was oncausedamage, but didn't work, it doesn't even write to the log.

My class extends mutator, maybe I should try other approach?

I've read of a mod with some rpg characteristics, that has a vampirish power up, so maybe I'll look that code to find something.

Help appreciated :xcahik_:

Extend mutator and include a game rules - some of the 'Light' mutators will show you how to do that. You can then over-ride the damage functions from there.

Thanks!!
I tried to extend GameRules before but couldn't make it work (but with each hour struggling I'm understanding a little more, or so I wish),
I'm sure I was trying to over-ride the wrong function.
The vampire mod is working (no network test), I'm going to do the random part and then add to svn to get some comments from you all.

In the previous MutatorWeek, you can find everything you need to get the Random controller
key words (GameReplicationInfo, ForEach and Rand) :rolleyes:

Another question about UIScene, mine is fullScreen, how can I set dimension to my UIScene ?

It's always full screen - just don't draw over the bits you don't want to show menus - leave it blank.

Hi All,
I release a new one called "Surprise Gift". The aim of this mutator was to touch the UIScene part of Unrealscript.
Basically, the mutator logic is contained in the scorekill method of a new gamerule. It displays randomly to the killer an UIScene. The killer just need to wait the countdown to finish and receives its gift between weapons ammo and death !!!

As the UIScene doesn't extend Actor, I implemented an "heavy" listener mechanism. It is composed of an actor "counterActor" which has an array of listeners (such as the UIScene) it starts a timer and send notification to all listeners. The counterActor can be itself a listener.
In my gamerule, 2 counterActor are used one to update the countdown label and one to update the giftlabel

Another thing required, the UIScene must have this field in its defaultproperties bPauseGameWhileActive=false, if not the counters won't never start as the UIScene pause the game.
