apply alpha to tsStatic Object base distance.

this resource port AlphaLOD for Torque 3D 1.1 Final.
this resource possible instead general object LOD.
apply alpha to tsStatic Object base distance from cam.

i tested Torque 3D Pro.

open 'tsStatic.h' and add below code in 'class TSStatic : public SceneObject' class.

// Mquaker :: Add AlphaLOD Logic >>>
   protected:
	   bool	mUseAlphaLod;
	   F32	mAlphaLODStart;
	   F32	mAlphaLODEnd;
	   F32	mAlphaLOD;
	   bool	mInvertAlphaLod;

   public:
	   void setAlphaLOD(bool enable, F32 start, F32 end, bool inverse)
	   {
		   mUseAlphaLod		= enable;
		   mAlphaLODStart	= start;		
		   mAlphaLODEnd		= end;		
		   mInvertAlphaLod	= inverse;	
	   }
   // Mquaker :: Add AlphaLOD Logic <<<

open 'tsStatic.cpp' and add below code in 'TSStatic::TSStatic()'.

// Mquaker :: Add AlphaLOD Logic >>>
   mUseAlphaLod		= false;
   mAlphaLODStart	= 100.0f;
   mAlphaLODEnd		= 150.0f;
   mInvertAlphaLod	= false;
   // Mquaker :: Add AlphaLOD Logic <<<

add below code in 'void TSStatic::initPersistFields()'.

// Mquaker :: Add AlphaLOD Logic >>>
   addGroup( "AlphaLOD" );
      addField( "ALODEnable",	TypeBool,	Offset(mUseAlphaLod,	TSStatic), "Turn on/off AlphaLod" );
      addField( "ALODStart",	TypeF32,	Offset(mAlphaLODStart,	TSStatic), "Distance of start AlphaLOD" );
      addField( "ALODEnd",		TypeF32,	Offset(mAlphaLODEnd,	TSStatic), "Distance of end AlphaLOD" );
      addField( "ALODInverse", TypeBool,	Offset(mInvertAlphaLod, TSStatic), "Invert AlphaLOD's Start & End Distance" );
   endGroup( "AlphaLOD" );
   // Mquaker :: Add AlphaLOD Logic <<<

add below code in 'void TSStatic::prepRenderImage( SceneRenderState* state )'.

// Mquaker :: Add AlphaLOD Logic >>>
   if (mUseAlphaLod)
   {
	   mAlphaLOD = 1.0f;
	   if ((mAlphaLODStart < mAlphaLODEnd) && mAlphaLODStart > 0.1f)
	   {
		   if (mInvertAlphaLod) {
			   if (dist <= mAlphaLODStart)
				   return;

			   if (dist < mAlphaLODEnd)
				   mAlphaLOD = ((dist - mAlphaLODStart) / (mAlphaLODEnd - mAlphaLODStart));
		   }
		   else {
			   if (dist >= mAlphaLODEnd)
				   return;

			   if (dist > mAlphaLODStart)
				   mAlphaLOD -= ((dist - mAlphaLODStart) / (mAlphaLODEnd - mAlphaLODStart));
		   }
	   }
   }
   // Mquaker :: Add AlphaLOD Logic <<<

add below code before 'mShapeInstance->animate();' in same function.

// Mquaker :: Add AlphaLOD Logic >>>
   if(mShapeInstance)   
   {
	   if (mUseAlphaLod)
	   {
		   mShapeInstance->setAlphaAlways(mAlphaLOD);             
		   S32 s = mShapeInstance->mMeshObjects.size();  

		   for(S32 x = 0; x < s; x++)      
		   {         
			   mShapeInstance->mMeshObjects[x].visible = mAlphaLOD;   
		   }
	   }
   }
   // Mquaker :: Add AlphaLOD Logic <<<

add below code in 'U32 TSStatic::packUpdate(NetConnection *con, U32 mask, BitStream *stream)'.

// Mquaker :: Add AlphaLOD Logic >>>
   if ( stream->writeFlag(mUseAlphaLod) )
   {
	   stream->write(mAlphaLODStart);
	   stream->write(mAlphaLODEnd);
	   stream->write(mInvertAlphaLod);
   }
   // Mquaker :: Add AlphaLOD Logic <<<

add below code in 'void TSStatic::unpackUpdate(NetConnection *con, BitStream *stream)'.

// Mquaker :: Add AlphaLOD Logic >>>
   mUseAlphaLod = stream->readFlag();
   if (mUseAlphaLod)
   {
	   stream->read(&mAlphaLODStart);
	   stream->read(&mAlphaLODEnd);
	   stream->read(&mInvertAlphaLod);
   }
   // Mquaker :: Add AlphaLOD Logic <<<

recompile your project and test...
