Problem with GameRules and Mutator

[legacy-dgouthro]

I have compiled my own damage modifier that give me 3 times powerful and reduce my damage inflicted by half.

However, I got error message indicate that G = spawn( class 'Danmutator') is mismatch! How I can fix it?

This part script made by me below:

class Danmutator extends Mutator;

var GameRules NextGameRules;

function PostBeginPlay()
{
local GameRules G;
local Pawn Mypawn;

super.PostBeginPlay( );
G = spawn( class'Danmutator' );
if( Level.Game.GameRulesModifiers == None )
Level.Game.GameRulesModifiers = G;
else
Level.Game.GameRulesModifiers.AddGameRules( G );

foreach AllActors(class 'Pawn', Mypawn)
{
if(Mypawn.IsA('PlayerPawn') == True){
Mypawn.zjump=1000;
Mypawn.default.zjump=1000;
Mypawn.DamageScaling=3;
Mypawn.default.DamageScaling=3;
}
}
}

Im not an unrealscript expert, but from what i can see, Danmutator is a subclass of the mutator class.

Gamerules != mutator

and you are assigning a mutator to gamerules

what exactly are u trying to do?
I've done something similar, perhaps if u look at my code it will help:

// Mutator Class
class MutVampFrenzy extends Mutator;

var() int healthDecrease;


function PostBeginPlay()
{
	local GameRules G;

	Super.PostBeginPlay();
	G = spawn(class'VampFrenzyGameRules');
	if ( Level.Game.GameRulesModifiers == None )
		Level.Game.GameRulesModifiers = G;
	else
		Level.Game.GameRulesModifiers.AddGameRules(G);
}
 //Whatever else needs to be done in the mutator

and

// GameRules class

class VampFrenzyGameRules extends VampireGameRules;
// You just stick whatever needs to be done as part of gamerules
