添加 Vector2 会使图像变得模糊

我有这段代码（XNA 4）：

int col = 0;
int row = 0;
foreach (Tile tile in TileList)
{
    if (col > NumTiles.X) {
        row++;
    }
    tile.Position = new Vector2(TileDimensions.X / 2, TileDimensions.Y / 2) + new Vector2(col * TileDimensions.X, row * TileDimensions.Y) + Margins + Position;
    col++;
}

我的问题是它使瓷砖变得模糊。

如果我改用此代码（我从该位置删除第一个 Vector2）：

int col = 0;
int row = 0;
foreach (Tile tile in TileList)
{
    if (col > NumTiles.X) {
        row++;
    }
    tile.Position = new Vector2(col * TileDimensions.X, row * TileDimensions.Y) + Margins + Position;
    col++;
}

它会很好地绘制它们。

编辑：我刚刚发现我需要将数字转换为整数，或者 spritebatch 在像素之间做了一些时髦的事情，这恰好模糊了我的图像

I have this code (XNA 4):

int col = 0;
int row = 0;
foreach (Tile tile in TileList)
{
    if (col > NumTiles.X) {
        row++;
    }
    tile.Position = new Vector2(TileDimensions.X / 2, TileDimensions.Y / 2) + new Vector2(col * TileDimensions.X, row * TileDimensions.Y) + Margins + Position;
    col++;
}

My problem is that it draws the tiles blurry.

If I use this code instead (I delete the first Vector2 from the position):

int col = 0;
int row = 0;
foreach (Tile tile in TileList)
{
    if (col > NumTiles.X) {
        row++;
    }
    tile.Position = new Vector2(col * TileDimensions.X, row * TileDimensions.Y) + Margins + Position;
    col++;
}

It draws them fine.

EDIT: I just found that I need to cast the numbers as integers, or the spritebatch does some funky inbetween pixel stuff which happens to blur my image
