Question

我想在我的RPG游戏中添加一些层次。但这失败了：

import java.awt.Graphics;
import java.awt.image.BufferedImage;
import java.io.IOException;
import javax.imageio.ImageIO;

public class TileSet {

public static final int TILEWIDTH = 64, TILEHEIGHT = 64;

  private BufferedImage[] tiles;

  public TileSet(String path, int sizeX, int sizeY) {
    tiles = new BufferedImage[sizeX * sizeY];
    BufferedImage tileSet;
    try {
      tileSet = ImageIO.read(TileSet.class.getResource(path));
    } catch (IOException e) {
      e.printStackTrace();
      return;
    }
    int i = 0;
    for(int y = 0; y < sizeY; y++) {
      for(int x = 0; x < sizeX; x++) {
        tiles[i++] = tileSet.getSubimage(x * (TILEWIDTH + 3), y * (TILEHEIGHT + 3), TILEWIDTH, TILEHEIGHT);
      }
    }
  }
  public void renderTile(Graphics g, int tileNum, int x, int y){
    g.drawImage(tiles[tileNum], x, y, TILEWIDTH, TILEHEIGHT, null);
  }
}

因此，问题出现在此行：

tiles[i++] = tileSet.getSubimage(x * (TILEWIDTH + 3), y * (TILEHEIGHT + 3), TILEWIDTH, TILEHEIGHT);

确切的错误是：

线程“ Thread-0”中的异常java.awt.image.RasterFormatException： [x +宽度）在Raster的外部 sun.awt.image.ByteInterleavedRaster.createWritableChild（未知来源）java.awt.image.BufferedImage.getSubimage（未知来源）在de.gandalf1783.TileSet。（TileSet.java:25）在 java.lang.Thread.run（未知）上的de.gandalf1783.Game.run（Game.java:57）来源）

RasterFormatException：（x + width）在Raster之外
