90% of the code comes from Tim at MaxGaming for TGE/A, 10% from myself to get it working in Torque3D.
http://www.yorkshirerifles.com/downloads/ribbons_Torque3D.zip

Make sure you've got ribbon.cpp/h and ribbonNode.cpp/h in T3D/fx and the ribbon shaders basicRibbonShaderP/V.hlsl in shaders/ribbons.

ribbons.cs goes in art/datablocks, don't forget to exec it in art/datablocks/datablockExec.cs.

ribbons.cs

{
   DXVertexShaderFile   = "shaders/ribbons/basicRibbonShaderV.hlsl";

      emitter = %emitter;
      position = %pos;
   };
   if(isObject(MissionCleanup))
      MissionCleanup.add(%r);

   return %r;
}

scripts/server/weapon.cs weaponImage::onFire function at the end.

// Create the projectile object
      %p = new (%this.projectileType)()
      {
         dataBlock = %this.projectile;
         initialVelocity = %muzzleVelocity;
         initialPosition = %obj.getMuzzlePoint(%slot);

         sourceSlot = %slot;
         client = %obj.client;
         sourceClass = %obj.getClassName();
      };
      MissionCleanup.add(%p);
	  
	  //yorks we now have a projectile so let's attach a ribbon to it
	    %ribbon = createRibbon(longRibbon, %obj.getMuzzlePoint(%slot));
        %p.mountObject(%ribbon, 0);
   }
}

Next lets add some ribbons to the Cheetah. scripts/server/cheetah.cs, onAdd function

// Mount the brake lights
   %obj.mountObject(%obj.rightBrakeLight, %this.rightBrakeSlot);
   %obj.mountObject(%obj.leftBrakeLight, %this.leftBrakeSlot);
   
   //yorks add ribbons!
   %ribbon1 = createRibbon(amberRibbon, %obj.getTransform());
   %ribbon2 = createRibbon(greenRibbon, %obj.getTransform());
   
   %obj.mountObject(%ribbon1, %this.rightBrakeSlot);
   %obj.mountObject(%ribbon2, %this.leftBrakeSlot);

And make sure we don't get console spam when the vehicle is removed.
scripts/server/vehicle.cs VehicleData::onRemove function

function VehicleData::onRemove(%this, %obj)
{
   //echo("\c4VehicleData::onRemove("@ %this.getName() @", "@ %obj.getClassName() @")");

   // if there are passengers/driver, kick them out
   for(%i = 0; %i < %obj.getDatablock().numMountPoints; %i++)
   {
      if (%obj.getMountNodeObject(%i))
      {
         %passenger = %obj.getMountNodeObject(%i);
         if(isMethod(%passenger, doDismount))//yorks in
            %passenger.getDataBlock().doDismount(%passenger, true);
         else//yorks in
            %passenger.delete();//yorks in for ribbons etc
      }
   }
}

@Steve: Muchimas Gracias! Dunno why I wasn't able to get the ribbon to mount to the weapon - seems to work fine now using your scripts...

[8bitprodigy]

Could you possibly upload another version of the video, but this time all the trails are the Nyan Cat trail and everything makes the Nyan Cat song when it's moving? Even the Cheetah, but only when it's moving.

Thanks in advance.

@

8bitprodigy Well volunteered to accept this important assignment yourself!

[Gibby]

the create function needs to look like this:

Code: Select all

function createRibbon(%emitter, %pos)
{
   %r = new RibbonNode()
   {
      datablock = DefaultRibbonNodeData;
      Ribbon = %emitter;  //Gibby should be 'Ribbon' not 'emitter'
      position = %pos;
   };
   if(isObject(MissionCleanup))
      MissionCleanup.add(%r);
 
   return %r;
}

"Emitter" works fine for me in v3.6.2 with the code files I'm using.

[highground]

Hey Steve, followed instructions, go to compile the engine and get 42 errors???

01.'GFXVertexPCNTT' : undeclared identifier
02.'GFXVertexPCNTT' : undeclared identifier
03.'GFXVertexBufferHandle' : no appropriate default constructor available
04.'GFXVertexPCNTT' : undeclared identifier
05.'const GFXVertexFormat *getGFXVertexFormat(void)' : could not deduce template argument for 'T'
06.'GFXVertexPCNTT' : undeclared identifier
07.'GFXVertexBufferHandle<T>::set' : cannot convert 'this' pointer


Etc....Has anyone else experienced this??

My bad! I forgot to include the source/gfx/gfxVertexTypes.cpp/h changes.

I've updated the zip file so if you redownload it the new code files will be there.

@Steve: I think that was what had held me up for a day, I had it working fine per your instructions in 3.6.1 but had to change it to work with 3.7+

[jnovosel]

Using the 3.8 codebase I added ribbons to my projectiles and have noticed a strange side effect - shooting bullets into the terrain leaves a RibbonNode object at the point of impact for each projectile. Jump into mission edit mode after shooting some of these into the ground to see them. I modified the projectile.cs onExplode and onCollision script files to delete the ribbon. Seems to work but then thought about the projectiles that are shot into the air and hit nothing - are those ribbons being deleted when the projectile gets cleaned up. Checked the projectile.cpp code and added similar code to Projectile::onRemove() to check for the ribbon when the projectile gets deleted but this is sometimes crashing..not sure if removefromScene or Parent::onRemove handle the ribbon or not. Not sure of the implications of having tons of ribbonodes laying around but it can't be good.
Anyone else notice this?
