Mod Idea (I Failed).

[Raiiiny]

the laser on guns in DX was a fail, absolutely no purpose.
can anyone mod the laser so that its viewable by other players when you toggel it, or so that it stays on?

i had it working, but couldn't get it to aim right from my gun to the crosshairs :[

something like this ^

[MainMan]

Are you trying to get this to work in multi or single player?

[Baleout]

viewable by other players

[Raiiiny]

DXMP.

also, have another idea i've been wanting to try. would it be
possible to make a DT_Sprite npc that can walk an turn? would need
some way to sence what side of the npc the player is looking at to change
the sequence of textures accordingly... something like doom64.
or possibly make a square mesh an add a texture to each side that
changes if its walking or standing still, not sure how that'd look though.

awe, come on. is this really to much of a challange for alpha?
nobody, allan or alex should be able to have this whipped together in 10min.

just need to add a laser emitter an adjust the vectors :/
think an actual "Laser" (austin powers came to mind, sorry lol.) would look great in foggy/dark maps.

On another note, anyone have the code for dual pistols or a mod?
need the script for a new weapon on my mp server.

[~DJ~]

Overwriting the function ToggleLaser and adding ForEach AllActors while showing it might work.

That's just my opinion...

[Raiiiny]

I had it working. i just couldn't get it to aim right, from my gun to where i was pointing :/
deleted the old code i think. just starting to play again. may look for it or start from scratch if no one goods up to the task? im like moderate at best when it comes to coding, still learning.

[Aidan]

Well.. The point of lasers in Single Player was to create a challenge for yourself if you were to turn your crosshairs off. Doing so, you would need the laser modification to create that crosshair for that weapon.

In MP, well..... That's another story.

You want to be able to see the whole laser trail, and not just where it points to, correct?

[Raiiiny]

exactly
i love mp. really wanted to make a creepy co-op map, but i need the laser
an i need to finish afew other mods before i start.

[~DJ~]

I am not that sure.. but there's a class called LaserEmitter, you might see that stuff, very useful imo.

[Raiiiny]

yeah, thats what i used. its the vectors that got me stumped.
if someone wants to give it a go, i used Deadalus08's 'weaponlasergun' for refrence to get it working.

Code: Select all

var LaserEmitter emitter;
var float zapTimer;
var vector GunLocation;
var vector lastHitLocation;

// force Fire damage
function name WeaponDamageType()
{
   return 'Flamed';
}

function ProcessTraceHit(Actor Other, Vector HitLocation, Vector HitNormal, Vector X, Vector Y, Vector Z)
{
   Super.ProcessTraceHit(Other, HitLocation, HitNormal, X, Y, Z);

   //in cases of successive firing, it may happen that a new emitter is created before the previous one
   //is destroyed. This corrects the problem.
   if (emitter!=None)
      emitter.Destroy();
   
   //creates a laser beam
   emitter = Spawn(class'LaserEmitter',Self);
   if (emitter != None)
      emitter.Instigator = Pawn(Owner);
   
   //it keeps firing for 0.3 seconds
   zapTimer = 0.3;
}

// intercept the hit and turn on the emitter
function NewTrace()
{
   local vector HitLocation, HitNormal, StartTrace, EndTrace, X,Y,Z;
   local actor Other;
   local Pawn PawnOwner;

   //old - taken from the original Trace() function
   
   PawnOwner = Pawn(Owner);

   Owner.MakeNoise(PawnOwner.SoundDampening);
   GetAxes(PawnOwner.ViewRotation,X,Y,Z);
   StartTrace = Owner.Location + CalcDrawOffset() + FireOffset.X * X + FireOffset.Y * Y + FireOffset.Z * Z;
   AdjustedAim = PawnOwner.AdjustAim(1000000, StartTrace, 2*AimError, False, False);   
   
   EndTrace = StartTrace;
   X = vector(AdjustedAim);
   EndTrace += (1000000 * X);
   Other = PawnOwner.TraceShot(HitLocation,HitNormal,EndTrace,StartTrace);

   //new - upgrades the origin and destination of the beam   
   if (emitter != None)
   {
      GunLocation=Owner.Location + CalcDrawOffset() + FireOffset.X * X + FireOffset.Y * Y + FireOffset.Z * Z;
      emitter.SetLocation(GunLocation);
      emitter.SetRotation(Rotator(HitLocation - emitter.Location));
      emitter.TurnOn();
      emitter.SetBase(Owner);
      lastHitLocation = HitLocation;
   }
}

function Tick(float deltaTime)
{
   Super.Tick(deltaTime);

   if (zapTimer > 0)
   {
      zapTimer -= deltaTime;

      // updates the rotation of the emitter
      NewTrace();

      if (zapTimer < 0)
      {
         zapTimer = 0;
         emitter.Destroy();
      }
   }
}

function Destroyed()
{
   if (emitter != None)
   {
      emitter.Destroy();
      emitter = None;
   }
   Super.Destroyed();
}

Drawing the whole laser trail would be a replication/FPS drop nightmare, and making it move would be worse still.
Making a moving dot is the lesser of two evils, however it still requires frequent Trace operations during something like Tick, a global variable for your dot, and enough replication jiggery-pokery to make Baby Jesus cry.

That, and you have to bare in mind that using the laser sight is hard-coded to give weapons 100% accuracy while in use.

[Raiiiny]

I honestly don't think it'd effect the fps too much. i wouldn't get rid of the
original laser either. was simply thinking of having the laser emitter spawned, an tick updating the tracers vectors.

Something like this

Code: Select all

simulated function PreBeginPlay()
{
   Super.PreBeginPlay();

   {
   emitter = Spawn(class'LaserEmitter',Self);
   if (emitter != None)
      emitter.Instigator = Pawn(Owner);
   }
}

function Tick(float deltaTime)
{
   Super.Tick(deltaTime);
}

just not sure how to adjust the vectors, hmm. you really don't think it'd work?

[Allan]

It won't. The beam on LaserEmitters doesn't replicate.

Mind you, I have managed to make a laser dot that (should) move in MP.

Code: Select all

var LaserSpot LX;

replication
{
   Reliable if(Role==ROLE_Authority)
      LX;
   Unreliable if (Role==ROLE_Authority)
      MoveLaserSpot;
}

function MoveLaserSpot()
{
   local Rotator PR,V;
   local Vector HL, HN, TStart, TEnd;
   local vector X,Y,Z;
   local Pawn POwner;
   local Actor A;

   POwner=Pawn(Owner);

   if(POwner==None)
   {
      return;
   }
   if(!bLasing)
   {
      return;
   }

   GetAxes(POwner.ViewRotation,X,Y,Z);

   TStart = ComputeProjectileStart(X, Y, Z);
   V = POwner.AdjustAim(1000000,TStart, 0, False, False);
    TEnd = TStart + 0.0 * (FRand()-0.5)*Y*1000 + 0.0 * (FRand()-0.5)*Z*1000;
    TEnd += MaxRange * vector(V);
   A=Trace(HL,HN,TEnd,TStart,True);

   if(LX==None)
   {
      LX=spawn(class'LaserSpot',POwner,,HL,POwner.ViewRotation);
   }
   else
   {
      LX.SetLocation(HL);
      LX.SetRotation(POwner.ViewRotation);
      if(LX.bHidden)
      {
         LX.bHidden=False;
      }
   }
}

Just stick that at the start of the code of any weapon you want to have use the MP laser dot.

[Raiiiny]

ah thanks bro, your awsome!

Edit: It keeps saying unexpected error at end of script.
no matter what i do its always the same line as 'defaultproperties', could just be conflicting with my code. i'll try it on a regular weapon later.

[~DJ~]

Just add } before default properties..

[~ô¿ô~Nobody~]

I created a MP working laser emitter.. with the effect being drawn on the client and the other stuff being performed on the server..
It's part of SG_MOD153 but it's still not finalized, though.

[~DJ~]

Omg, I never knew that, sneaky!

I can't wait

[Vexus]

What about those laser trip wires that make the alarmunits go crazy?

maybe do something with those, like adding an invisible one on the gun or something.

[~DJ~]

that, my friend.. is called Laser Emitter.

[~ô¿ô~Nobody~]

..the thing we were talking about the past few posts.

[Vexus]

rofl, sorry, I didn't really take the time to read that whole

Code: Select all

code

part.

[~ô¿ô~Nobody~]

Me neither, tbh.

[Allan]

Most of it is default DeusExWeapon Tick copy-pasta.

Can't blame ya.
