Problems with target tracking

@Stefan
The ret variable in interpolateTick() is just a MatrixF, so it doesn't have a getRenderPosition() call (that I know of). The matrix data is gotten from the getRenderEyeTransform though, so I think I'm doing what your suggesting.

mHead.x = -0.037230; //During interpolateTick
mHead.x = 0.018615; //During interpolateTick
mHead.x = 0.018609; //During ProcessTick
mHead.x = 0.018615; //During ProcessTick
mHead.x = -0.037230; //During interpolateTick
mHead.x = 0.018615; //During interpolateTick
mHead.x = -0.037230; //During interpolateTick
mHead.x = 0.018615; //During interpolateTick
mHead.x = -0.037230; //During interpolateTick
mHead.x = 0.018609; //During ProcessTick
mHead.x = 0.018615; //During ProcessTick
mHead.x = -0.037230; //During interpolateTick

if(lockOnTarget != NULL){
		// variable setup.
		Point3F objPos, vec;
		MatrixF ret;
		F32 pitch, yaw;


		// Face the target.
		lockOnTarget->getRenderEyeTransform( &ret );
		objPos = ret.getPosition();

		pos = delta.pos + delta.posVec * dt;
		vec = objPos - pos;
		vec.normalizeSafe();
		MathUtils::getAnglesFromVector(vec, yaw, pitch);
		rot.z = yaw;

		mHead.x = 0;//mClampF(mHead.x + pitch + 100, mDataBlock->minLookAngle, mDataBlock->maxLookAngle);
		Con::warnf("interpolate: %f", mHead.x);
	}

// First some variable setup
			Point3F vec, pos, objPos;
			VectorF rotVec(0, 0, 0);


			// We should face the target now. Code from camera trackObject mode.
			MatrixF ret;
			lockOnTarget->getRenderEyeTransform( &ret );
			objPos = ret.getPosition();
			mObjToWorld.getColumn(3,&pos);
			vec = objPos - pos;
			vec.normalizeSafe();
			F32 pitch, yaw;
			MathUtils::getAnglesFromVector(vec, yaw, pitch);
			rotVec.x = -pitch - mRot.x;
			rotVec.z = yaw - mRot.z;
			if(rotVec.z > M_PI_F)
				rotVec.z -= M_2PI_F;
			else if(rotVec.z < -M_PI_F)
				rotVec.z += M_2PI_F;

			//mRot.x += rotVec.x;
			mRot.z += rotVec.z;

			// Now...we need to set the rot around the x rot (pitch)
			// The example for this is taken from getAIMove.
			F32 xDiff = objPos.x - pos.x;
			F32 yDiff = objPos.y - pos.y;
			F32 vertDist = (objPos.z - pos.z) - 2; // -2 is because he kept looking above the head.
			F32 horzDist = mSqrt(xDiff * xDiff + yDiff * yDiff);
			F32 newPitch = mAtan2( horzDist, vertDist ) - ( M_PI_F / 2.0f );
			if (mFabs(newPitch) > 0.01f) 
			{
				Point3F headRotation = getHeadRotation();
				// We don't set a *move because its too late here.
				// We'll update the look ourselves!  Yay hard way?
				mHead.x = mClampF(mHead.x + newPitch - headRotation.x,mDataBlock->minLookAngle,
					mDataBlock->maxLookAngle);
				Con::printf("processTick: %f", mHead.x);
			}
