Hey how would you use cheats like tantalus in uc for something like a tantalus gun.

Forgive my ignorance, but what is UC?

Unreal Console? or Unreal Code(Script)?

Why make a gun that uses a tantalus cheat, why not just make it a very high hitdamage.

So what you're saying is... you want a gun, that kills people? 'Cause that's a new idea...

Ales, what IS the point in having a gun which tantalus's people...

So it can kill invincible stuff as well? And that boomy effect.

Its was an example now is there anyway to do this?

If you mean a weapon that can give the effect of a cheat, then yeah probably.

If you mean a weapon that cheats, then your out of your mind.

Yeah it is possible. Just take a look at the code in exec function tantalus in the player class, and put it into the processtracehit() in the weapon class. Hang on I'll find the code for ya.

Make me a gun that flys around and tries to tantalus me and I will truly be impressed.

From the player class we can extract:

Code: Select all

exec function Tantalus()
{
   local Actor            hitActor;
   local Vector           hitLocation, hitNormal;
   local Vector           position, line;
   local ScriptedPawn     hitPawn;
   local DeusExMover      hitMover;
   local DeusExDecoration hitDecoration;
   local bool             bTakeDamage;
   local int              damage;

   if (!bCheatsEnabled)
      return;

   bTakeDamage = false;
   damage      = 1;
   position    = Location;
   position.Z += BaseEyeHeight;
   line        = Vector(ViewRotation) * 4000;

   hitActor = Trace(hitLocation, hitNormal, position+line, position, true);
   if (hitActor != None)
   {
      hitMover = DeusExMover(hitActor);
      hitPawn = ScriptedPawn(hitActor);
      hitDecoration = DeusExDecoration(hitActor);
      if (hitMover != None)
      {
         if (hitMover.bBreakable)
         {
            hitMover.doorStrength = 0;
            bTakeDamage = true;
         }
      }
      else if (hitPawn != None)
      {
         if (!hitPawn.bInvincible)
         {
            hitPawn.HealthHead     = 0;
            hitPawn.HealthTorso    = 0;
            hitPawn.HealthLegLeft  = 0;
            hitPawn.HealthLegRight = 0;
            hitPawn.HealthArmLeft  = 0;
            hitPawn.HealthArmRight = 0;
            hitPawn.Health         = 0;
            bTakeDamage = true;
         }
      }
      else if (hitDecoration != None)
      {
         if (!hitDecoration.bInvincible)
         {
            hitDecoration.HitPoints = 0;
            bTakeDamage = true;
         }
      }
      else if (hitActor != Level)
      {
         damage = 5000;
         bTakeDamage = true;
      }
   }

   if (bTakeDamage)
      hitActor.TakeDamage(damage, self, hitLocation, line, 'Tantalus');
}

Therefore, the bits we are interested in are:

Code: Select all

      hitMover = DeusExMover(hitActor);
      hitPawn = ScriptedPawn(hitActor);
      hitDecoration = DeusExDecoration(hitActor);
      if (hitMover != None)
      {
         if (hitMover.bBreakable)
         {
            hitMover.doorStrength = 0;
            bTakeDamage = true;
         }
      }
      else if (hitPawn != None)
      {
         if (!hitPawn.bInvincible)
         {
            hitPawn.HealthHead     = 0;
            hitPawn.HealthTorso    = 0;
            hitPawn.HealthLegLeft  = 0;
            hitPawn.HealthLegRight = 0;
            hitPawn.HealthArmLeft  = 0;
            hitPawn.HealthArmRight = 0;
            hitPawn.Health         = 0;
            bTakeDamage = true;
         }
      }
      else if (hitDecoration != None)
      {
         if (!hitDecoration.bInvincible)
         {
            hitDecoration.HitPoints = 0;
            bTakeDamage = true;
         }
      }
      else if (hitActor != Level)
      {
         damage = 5000;
         bTakeDamage = true;
      }
   }

   if (bTakeDamage)
      hitActor.TakeDamage(damage, self, hitLocation, line, 'Tantalus');

These deal with the checking if what you tantalused was a pawn, a mover (door) or a decoration.



Next we can place it into the weapon class. Firstly I had a look at the ProcessTraceHit function:

Code: Select all

simulated function ProcessTraceHit(Actor Other, Vector HitLocation, Vector HitNormal, Vector X, Vector Y, Vector Z)
{
   local float        mult;
   local name         damageType;
   local DeusExPlayer dxPlayer;

   if (Other != None)
   {
      // AugCombat increases our damage if hand to hand
      mult = 1.0;
      if (bHandToHand && (DeusExPlayer(Owner) != None))
      {
         mult = DeusExPlayer(Owner).AugmentationSystem.GetAugLevelValue(class'AugCombat');
         if (mult == -1.0)
            mult = 1.0;
      }

      // skill also affects our damage
      // GetWeaponSkill returns 0.0 to -0.7 (max skill/aug)
      mult += -2.0 * GetWeaponSkill();

      // Determine damage type
      damageType = WeaponDamageType();

      if (Other != None)
      {
         if (Other.bOwned)
         {
            dxPlayer = DeusExPlayer(Owner);
            if (dxPlayer != None)
               dxPlayer.AISendEvent('Futz', EAITYPE_Visual);
         }
      }
      if ((Other == Level) || (Other.IsA('Mover')))
      {
         if ( Role == ROLE_Authority )
            Other.TakeDamage(HitDamage * mult, Pawn(Owner), HitLocation, 1000.0*X, damageType);

         SelectiveSpawnEffects( HitLocation, HitNormal, Other, HitDamage * mult);
      }
      else if ((Other != self) && (Other != Owner))
      {
         if ( Role == ROLE_Authority )
            Other.TakeDamage(HitDamage * mult, Pawn(Owner), HitLocation, 1000.0*X, damageType);
         if (bHandToHand)
            SelectiveSpawnEffects( HitLocation, HitNormal, Other, HitDamage * mult);

         if (bPenetrating && Other.IsA('Pawn') && !Other.IsA('Robot'))
            SpawnBlood(HitLocation, HitNormal);
      }
   }
   if (DeusExMPGame(Level.Game) != None)
   {
      if (DeusExPlayer(Other) != None)
         DeusExMPGame(Level.Game).TrackWeapon(self,HitDamage * mult);
      else
         DeusExMPGame(Level.Game).TrackWeapon(self,0);
   }
}

We can see that the part here calling the damage is:

Code: Select all

      if ((Other == Level) || (Other.IsA('Mover')))
      {
         if ( Role == ROLE_Authority )
            Other.TakeDamage(HitDamage * mult, Pawn(Owner), HitLocation, 1000.0*X, damageType);

         SelectiveSpawnEffects( HitLocation, HitNormal, Other, HitDamage * mult);
      }
      else if ((Other != self) && (Other != Owner))
      {
         if ( Role == ROLE_Authority )
            Other.TakeDamage(HitDamage * mult, Pawn(Owner), HitLocation, 1000.0*X, damageType);
         if (bHandToHand)
            SelectiveSpawnEffects( HitLocation, HitNormal, Other, HitDamage * mult);

         if (bPenetrating && Other.IsA('Pawn') && !Other.IsA('Robot'))
            SpawnBlood(HitLocation, HitNormal);
      }

Therefore, when I put in code based on the tantalus command, the completed function will look like:

Code: Select all

simulated function ProcessTraceHit(Actor Other, Vector HitLocation, Vector HitNormal, Vector X, Vector Y, Vector Z)
{
   local float        mult;
   local name         damageType;
   local DeusExPlayer dxPlayer;

   local ScriptedPawn     hitPawn;
   local DeusExMover      hitMover;
   local DeusExDecoration hitDecoration;

   local bool             bTakeDamage;

   if (Other != None)
   {
      if (Other != Self)
      {
         //MM: ADDED===
         hitMover = DeusExMover(hitActor);
         hitPawn = ScriptedPawn(hitActor);
         hitDecoration = DeusExDecoration(hitActor);

         if (Other.bOwned)
         {
            dxPlayer = DeusExPlayer(Owner);
            if (dxPlayer != None)

         }
      }

      //MM: ADDED=======
      if (hitMover != None)
      {

            bTakeDamage = true;
         }
         SelectiveSpawnEffects( HitLocation, HitNormal, Other, 5000);
      }
      //==========




      //MM: ADDED=======
      else if ( (hitPawn != None) && (hitPawn != Pawn(Owner) )
      {

            hitPawn.HealthTorso    = 0;
            hitPawn.HealthLegLeft  = 0;
            hitPawn.HealthLegRight = 0;
            hitPawn.HealthArmLeft  = 0;
            hitPawn.HealthArmRight = 0;
            hitPawn.Health         = 0;
            bTakeDamage = true;
         }

         if (bHandToHand)
            SelectiveSpawnEffects( HitLocation, HitNormal, Other, 5000);

         SpawnBlood(HitLocation, HitNormal);
      }

            bTakeDamage = true;
         }
      }
      //=======


      //MM: ADDED=======
      if (bTakeDamage)
      {
         //MM: Take Damage must be called on the server (that's what Role_authority means)
         if(Role == ROLE_Authority)
         {
            Other.TakeDamage(5000, self, hitLocation, line, 'Tantalus');
         }
      }
      //======

   }
   if (DeusExMPGame(Level.Game) != None)
   {
      if (DeusExPlayer(Other) != None)
         DeusExMPGame(Level.Game).TrackWeapon(self,5000);
      else
         DeusExMPGame(Level.Game).TrackWeapon(self,0);
   }
}

Hope it helped!

I doubt it will have helped him.

~[A]Nobody~ wrote:I doubt it will have helped him.

Why?

Because he is not that experienced at coding. He cannot use the code without knowing the basics.

Yes, but I was just explaining what I was doing, to try and help him learn. But at the end, I just gave him a block of code that he can copy-and-paste, without understanding.

hmm. i see.

Just copy and paste the last bit into your weapon script dude. Try to read my explanation of how I made that code too, though - it will help you to learn

I still think making it a really high hitdamage would've been easyer.

Actually that's easy. Just change a player class mesh to "pistol" or whatever, make its weapon the "tantaluspistol" (coding it beforehand) and unlimited ammo.

Either that or just make the GM or GF meshes invincible so that the third person mesh is viewable only.
