Attaching a light to a ShapeBase object

by Denise Bacher · in Torque Game Engine · 09/24/2007 (10:33 am) · 2 replies

I've read this post (http://www.garagegames.com/mg/forums/result.thread.php?qt=26189) as well as a few others on this topic, and it seems like it should be fairly straight forward to attach a light to an object. But I still haven't been able to get it to work.

What I'm trying to do is attach an omni light to my flying vehicle. I don't really care where the light attaches at the moment, only that it does and that it moves around with my vehicle. What I'm currently trying is I've defined a fxLightData datablock "mLight", then in my flyingVehicle datablock I've included className = "Light" and defined:

function Light::onAdd(%this,%obj)
{
   %light = new fxLight()
   {
      dataBlock = "mLight";
      client = %this;
			
      selected = "0";
   };
   %light.attachToObject(%obj);
   
}

This isn't working, and %light isn't being assigned a value. Can anyone give me some insight or guidance on how to accomplish this.

Thanks,
Denise

Following the Lighting Demo:
%light = new volumeLight() {
         [b]dataBlock = "sgMountLight";[/b]
         rotation = "-0.357694 0.933839 9.9834e-009 180";
         scale = "1 1 1";
         Enable = "1";
         IconSize = "1";
         ParticleColorAttenuation = "1";
         Texture = "common/lighting/lightFalloffMono.png";
         lpDistance = "0.35";
         ShootDistance = "5";
         Xextent = "0.6";
         Yextent = "0.6";
         SubdivideU = "4";
         SubdivideV = "4";
         FootColour = "1.000000 1.000000 1.000000 0.182000";
         TailColour = "0.000000 0.000000 0.000000 0.000000";
      };

%light.attachToObject(%object);

This example makes spotlights. However, even after I change the sgMountLight datablock so SpotLight = 0, it still renders a spotlight. Does anybody know how to setup an omni light? Thanks.

Here's my datablock for making an omni light.

datablock sgUniversalStaticLightData(sgMountLight)
{
   className = "sgUniversalStaticLightData";
   LightOn = "1";

   UseNormals = "1";
   MountPoint = "0";
   MountPosition = "0 0 0";
   MountRotation = "-1 0 0 90";
};

also in the onAdd function I changed it from lightFalloffMono.png to corona.png
