java - 无法加载平铺 map (Libgdx)

Question

我尝试过使用不同的平铺 map 并使用 zlib 压缩类型。我在android下的assets文件夹中有png文件和tmx文件。

如果您需要更多信息，我会回复。任何帮助表示赞赏。谢谢

package com.mm.test1;

import com.badlogic.gdx.ApplicationAdapter;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.graphics.GL20;
import com.badlogic.gdx.maps.tiled.TiledMap;
import com.badlogic.gdx.maps.tiled.TmxMapLoader;
import com.badlogic.gdx.maps.tiled.renderers.OrthogonalTiledMapRenderer;

public class TestOne extends ApplicationAdapter {
    private TiledMap map;
    private OrthogonalTiledMapRenderer renderer;

    @Override
    public void create () {
        map = new TmxMapLoader().load("grass1.tmx");
        renderer = new OrthogonalTiledMapRenderer(map);
    }

    @Override
    public void render () {
        Gdx.gl.glClearColor(0,0,0,1);
        Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);

        renderer.render();
    }

    @Override
    public void dispose () {
        map.dispose();
        renderer.dispose();
    }
}

错误消息如下:

问题出在 .tsx (TileSet) 文件中。
进入 .tsx 文件并更改:
<image source="Downloads/TilesetGrass/TilesetGrass/overworld_tileset_grass.png" ... />
至
<image source="[relative path to your .png from asset folder]" ... />

通过为 TileMap 创建 TileSet，您可能选择了仍在下载文件夹中的 .png，因此您的 TileSet 指向路径:Downloads/TilesetGrass/TilesetGrass/overworld_tileset_grass.png显示在您的错误消息中。
