Spring RTS Engine

Code: Select all

	template<typename HF> int2 SelectGameInfoSector (HF hf)
	{
		float bestscore;
		int2 best (-1,0);

		for (int y=0;y<gsh;y++)
			for (int x=0;x<gsw;x++)
			{
				GameInfo& i=gameinfo[y*gsw+x];
				float score = hf(x,y,i);
				if (best.x < 0 || bestscore < score)
				{
					best=int2(x,y);
					bestscore=score;
				}
			}
		return best;
	}
Now you can write a function:

float GetSectorScore (int  x,int y,GameInfo& i) {
  return i.EnemyValue / i.EnemyPower;
}

or something...

Code: Select all

template<typename ElemType, int bw, int bh>
class StateMap 
{
public:
  enum { BlockW=bw, BlockH=bh };
  ElemType& Get (int x,int y) { 
   return blocks[(y/BlockH)*w+x/BlockW]; 
  }

  template<typename OtherStateMap>
  ElemType& GetFromOtherStateMapCoords(OtherStateMap &other, int x, int y) {
    int rx = x * OtherStateMap::BlockW;
    int ry = y * OtherStateMap::BlockH;
    return Get(rx,ry);
  }

  int w,h;
  ElemType *blocks;
};

Which you can use like:

StateMap<EnemyInfo, 32,32> enemyInfoMap;
StateMap<MetalInfo,64,64> metalInfoMap;

MetalInfo& mi = metalInfoMap.GetFromOtherStateMapCoords (enemyInfoMap, 3, 5);

// now mi points to the metal info element on (3,5) on the enemyinfo map.
