我正在尝试修改字典中的值,但编译器会抛出KeyNotFoundException
. 我敢肯定,我在字典中声明了该键,因为我正在调用GenerateEmptyChunks()
方法,该方法用具有位置键的块填充字典,而关卡生成器的值是空的。我检查了调试器和Chunks
字典对象是否正确填充了键和值。CompareTo
是我不工作的方法造成的吗?如果是,我如何修改CompareTo
方法来返回正确的值?
public Dictionary<WPoint, WChunk> Chunks = new Dictionary<WPoint, WChunk>();
GenerateEmptyChunks()方法:
public void GenerateEmptyChunks(int Xcount, int Ycount)
{
for(int x = 0; x <= Xcount; x++)
{
for (int y = 0; y <= Ycount; y++)
{
this.Chunks.Add(new WPoint(x, y), new WChunk(x, y));
}
}
}
AddBlock()方法由每个图块的级别生成器调用:
public void AddBlock(WPoint location, int data)
{
this.Chunks[location.GetChunk()].AddTile(new WTile(location, data));
}
Wchunk对象:
public class WChunk
{
public int ChunkX;
public int ChunkY;
public SortedDictionary<WPoint, WTile> Tiles = new SortedDictionary<WPoint, WTile>();
public WChunk(int posX, int posY)
{
ChunkX = posX;
ChunkY = posY;
}
public void AddTile(WTile tile)
{
Tiles.Add(tile.GetLocation(), tile);
}
}
WPoint对象:
public class WPoint : IComparable
{
public float X;
public float Y;
public WPoint(float x, float y)
{
X = x;
Y = y;
}
public WPoint GetChunk()
{
//Oprava pre bloky mensie ako (1,1)
if (X <= 16 && Y <= 16)
{
return new WPoint(0, 0);
}
else
{
double pX = (double)(X / 16);
double pY = (double)(Y / 16);
return new WPoint((int)Math.Floor(pX), (int)Math.Floor(pY));
}
}
public int CompareTo(object obj)
{
WPoint point2 = (WPoint)obj;
if (point2.X == this.X && point2.Y == this.Y)
{
return 0;
}
else if (point2.X >= this.X && point2.Y >= this.Y)
{
return -1;
}
else
{
return 1;
}
}
}
任何想法为什么编译器拒绝键,当它们在字典中时?
