Remption Mutator

YoYoBatty · Mar 26, 2011

Mutator name: Redemption
Effects: Restores your health and teleports you back to the starting position if your health drops below 10%. This will only work once during the game so use it wisely.

I haven't gotten to chance to test this with other people let me know what you think of this mutator and tell me if it works online or not.

Edit: Note: You should never use this on any mission map of any kind as it will break the game.

so does this happen automatically or with a button press? I don't wanna waste my "redemption" if theres just a clot left on the level, but it'd come in handy if i was getting FP raged...

This only work if you're under 10hp and above 0, you can still get killed in one blow (example: own grenade).

My suggestions:
1) Use PreventDeath() from a GameRules.
2) Why not make this only effective while carrying a expensive item from trader? Plus this will be easy to check in PreventDeath() without modifying the pawn class.

Yes GameRules was my first method for this mutator, however I never really got it to work properly, I'll give it another shot and see how it works out.

Edit: I can't seem to get this to work at all for some reason.

Phada mentioned expensive stuff, could you include a parameter saying something along the lines of if networth < 1000 don't use redemption? That would save some greif i think.

YoYoBatty · Mar 27, 2011

Hmm... Sounds interesting, I may implentent this in the future when I have time.

Tendency · Mar 27, 2011

It works on dedicated servers. Its just not compatible with ServerPerks as it prevents you from selecting any perks.

I don't know what I'm doing wrong, can somebody take a look at this and help me?

Code:

class RedemptionMessage extends CriticalEventPlus;
var() localized string SwitchMessage[10];
static function string GetString (optional int Switch, optional PlayerReplicationInfo RelatedPRI_1, optional PlayerReplicationInfo RelatedPRI_2, optional Object OptionalObject)
{
 if ( (Switch >= 0) && (Switch <= 9) )
  return Default.SwitchMessage[Switch];
}
defaultproperties
{
     SwitchMessage(0)="You have been Redeemed!"
     DrawColor=(B=0,G=0,R=220)
     StackMode=SM_Down
     PosY=0.800000
}

Code:

//=============================================================================
// RedemptionMutator.
//
// If your health reaches zero or below, you will be fully healed and teleported to a random starting position.
//=============================================================================
class RedemptionMutator extends Mutator;
var KFPlayerReplicationInfo KFPRI;
function ModifyPlayer(Pawn Other)
{
    local NavigationPoint NP;
    local float AmountHealed;
    local KFHumanPawn KFP;
        KFP = KFHumanPawn(Other);
 AmountHealed = (KFP.Health * 1.5) * KFPRI.ClientVeteranSkillLevel;
 if ( KFP != None && KFP.Health <= 10 )
 {
      KFP.Health *= AmountHealed;
      PlayerController(KFP.Controller).ReceiveLocalizedMessage(class'MutRedemption.RedemptionMessage',0);
      for (NP = Level.NavigationPointList; NP != None; NP = NP.NextNavigationPoint)
      {
       if (NP.IsA('PlayerStart'))
       {
        KFP.SetLocation(NP.Location);
       }
      }
 }
 Super.ModifyPlayer(Other);
}
defaultproperties
{
     GroupName="KF-Redemption"
     FriendlyName="Redemption"
     Description="Gives you a second chance at life."
     bAddToServerPackages=True
     bAlwaysRelevant=True
     RemoteRole=ROLE_SimulatedProxy
}

I don't understand what you're trying to do, ModifyPlayer() is only called on spawn/respawn.
Pawn's health will be always 100 (HealthMax) here.

Also you don't need to change bAlwaysRelevant or RemoteRole for a normal mutator use.
And for the message you only use one, why you put a 10 vars string chain?

Still the same prob anyway, you can still be killed in one blow by checking health.

Thanks for clearing that up, I now know how to fix this!

I've always used them in mutators, I guess I don't really need it here. I shall remove them.

I copied it from BullpupSwitchMessage.uc

I want them to be killed if there health goes from 11 or more down to 0 though.

Answers are in green and thanks.

Ah ok, never mind then

New code (still doesn't work :S):

"Other" refer to nothing

If you want to check pawn health here you have to use the ControllerList:

Code:

function Tick( float DeltaTime )
{
    local Controller C;

    for (C=Level.ControllerList; C!=None; C=C.NextController)
        if (C.bIsPlayer && C.Pawn != None && C.Pawn.Health <= 10 && C.Pawn.Health > 0)
            RedeemPlayer(C.Pawn);
}

function RedeemPlayer(Pawn P) {
    P.Health = P.HealthMax;
    [...]
}

But the clean way to check health change with a mutator is with NetDamage() from a GameRules, the function is called every time that a pawn receives damage.

Also you're not relocating the pawn to a random starting point but to every PlayerStart until the last one in the list.

Thanks for clearing that up, I understand now. I'm usually pretty good with writing mods, I'm not sure why I had so much trouble with this one in particular.

New download links, this should and hopefully will work without any of the reported bug and glitches, see original post download. Thanks to Phada for his assistance!

EDIT: JUST NOW I UPDATED THE DOWNLOAD LINK FOR A FINAL TIME, PLEASE DOWNLOAD THE LATEST VERSION AS IT HAS AN IMPORTANT FIX IN IT! This fix will prevent a player from being redeemed more than once in the game, it should work online flawlessly.

Phada · Mar 29, 2011

New suggestions ^^

If you run the Tick client side (need the simulated prefix, bAlwaysRelevant=True and RemoteRole=ROLE_SimulatedProxy now), maybe you don't have check all controllers in the list, try this:

Code:

local PlayerController PC;

PC = Level.GetLocalPlayerController();
if (PC != None && PC.Pawn != None && PC.Pawn.Health <= 10 && PC.Pawn.Health > 0) {
    RedeemPlayer(PC.Pawn, PC);
    Disable('Tick');
}

You can remove the bool, disable() will just stop the function to run which is enough to do it once.

In the function you forgot to set the rotation:

Code:

if (NP != None) {
    P.SetLocation(NP.Location);
    P.SetRotation(NP.Rotation);
}

Does it work with ServerPerks now?

It should 100%

Tendency · Mar 31, 2011

It works with ServerPerks now. The only problem now is its hit or miss. It doesnt always respawn you. It mostly 50/50.

Was your health 10 or below before you died? If its greater than 10 and a hit kills you, you don't respawn.
