Torque Shadow Bug

UPDATED 1/2/2004 - A cleaner and somewhat more efficient method (simpler change, less dereferncing, bigger compile/link).

Here's a complete alternative correction for this bug derived in part from Mark Harmon's posted code which eliminates all the hard coded light references and substitutes the sun's direction vector for them instead. It correctly renders the player shadow on DIF's and terrain, corresponding to the sun's position.

In scenegraph.h immediately following the statements:

extern SceneGraph* gClientSceneGraph;
extern SceneGraph* gServerSceneGraph;

paste the following code

inline Point3F gGetSunDirection()
{
 LightManager *pLightMgr=gClientSceneGraph->getLightManager();
 if ( pLightMgr->getNumLights() > 0 ) // we have lights
   return  pLightMgr->getLight(0).mDirection; //first is sun  
 return Point3F(0.57735f, 0.57735f, -0.57735f); // default
}

In renderShadow(F32 dist, F32 fogAmount) of both shapebase.cc and tsstatic.cc replace

Point3F lightDir = (0.57f,0.57f,-0.57f);

with

Point3F lightDir = gGetSunDirection();

In SceneObject::installLights of sceneobject.cc replace

light.mDirection = VectorF(0.57735f, 0.57735f, -0.57735f);

with

light.mDirection = gGetSunDirection();
