获取精灵在第几象限以某个精灵为准

Vec2 VectorPoint = (movePoint - startPoint).getNormalized();
		
		//判断在第几象限   
		if(VectorPoint.y > 0 && VectorPoint.y < 1)
		{
				//第一象限
			if(VectorPoint.x > 0 && VectorPoint.x < 1 )
		{
			//获取移动位置
			Vec2 moveDistance = Vec2(startX + moveSpeed,startY + moveSpeed);
		
			}
			else if(VectorPoint.x < 0 && VectorPoint.x > -1)  //第二象限
		 		{
		 
		 		}
	 	}
			else if(VectorPoint.y < 0 && VectorPoint.y > -1)
		 	{
		 		//第三象限
				if(VectorPoint.x > -1 && VectorPoint.x < 0)
		 		{
		 
		 		}
		 		else if(VectorPoint.x > 0 && VectorPoint.x < 1) //第四象限
		 		{
		 
		 		}
