1. 移动
   • Bresenham,视线（略）,拦截
     

     // Bresenham
     if (deltaCol > deltaRow) {
         fraction = deltaRow * 2 - deltaCol;
         while (nextCol != endCol) {
             if (fraction >= 0) {
                 nextRow = nextRow + stepRow;
                 fraction = fraction - deltaCol;
             }
             nextCol = nextCol + stepCol;
             fraction = fraction + deltaRow;
             pathRow[currentStep] = nextRow;
             pathCol[currentStep] = nextCol;
             currentStep++;
         }
     } else {
         fraction = deltaCol * 2 - deltaRow; 
         while (nextRow != endRow) { 
             if (fraction >= 0) { 
                 nextCol = nextCol + stepCol; 
                 fraction = fraction - deltaRow; 
             }
             nextRow = nextRow + stepRow;
             fraction = fraction + deltaCol;
             pathRow[currentStep] = nextRow;
             pathCol[currentStep] = nextCol;
             currentStep++;
         } 
     }
