无法加载文件：资产

Question

我正在尝试在 Eclipse 上渲染 Tiled Map libGDX。这是我渲染地图的代码。这是我学校的作业。我真的需要帮助。一直提示找不到文件！

package screens;

import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.Screen;
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 Play implements Screen {

    private TiledMap map;
    private OrthogonalTiledMapRenderer otmr;

    @Override
    public void dispose() {
        map.dispose();
        otmr.dispose();

    }

    @Override
    public void hide() {
        dispose();

    }

    @Override
    public void pause() {
        // TODO Auto-generated method stub

    }

    @Override
    public void render(float arg0) {
        Gdx.gl.glClearColor(0, 0, 0, 1);
        Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);

        otmr.render();

    }

    @Override
    public void resize(int arg0, int arg1) {
        // TODO Auto-generated method stub

    }

    @Override
    public void resume() {
        // TODO Auto-generated method stub

    }

    @Override
    public void show() {

        map = new TmxMapLoader().load("assets/level1.1.tmx");

        otmr = new OrthogonalTiledMapRenderer(map);

    }

}

这是 tmx 级别文件的文本。右键单击 level1.1.tmx 并单击打开 with/text 编辑器

时出现的文本

这是 TileSet 的文本

这里是错误

请帮忙!!!!

Answer 1

您的设置有几个问题：

WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by org.lwjgl.LWJGLUtil (file:/D:/Downloads/libGDX/libGDX/gdx-backend-lwjgl.jar) to method java.lang.ClassLoader.findLibrary(java.lang.String)

现在可能不会影响你，但这意味着你需要使用 JDK 8 https://github.com/libgdx/libgdx/issues/4927

Caused by: java.io.FileNotFoundException: assets (Access is denied)

在这里它抛出这个异常，因为它找不到资产文件夹。只要 assets 文件夹在你的项目中，它应该默认工作，但首先尝试使用绝对路径，看看它是否工作。

例如：

map = new TmxMapLoader().load("D:/assets/level1.1.tmx");

另外请注意，如果它是一个 android 项目，请看这里：
