Question

已解决!!! 似乎图片的大小不成比例，例如64x64,128x128

制作了一个基本的Hello World，这个编译好了，但是当我尝试显示基本图形时，所有显示的都是黑色。基本上按照一个单词的教程，它似乎仍然这样做。任何人的想法？

package com.me.mygdxgame;

import com.badlogic.gdx.ApplicationListener;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.graphics.Color;
import com.badlogic.gdx.graphics.GL10;
import com.badlogic.gdx.graphics.OrthographicCamera;
import com.badlogic.gdx.graphics.Texture;
import com.badlogic.gdx.graphics.Texture.TextureFilter;
import com.badlogic.gdx.graphics.g2d.BitmapFont;
import com.badlogic.gdx.graphics.g2d.Sprite;
import com.badlogic.gdx.graphics.g2d.SpriteBatch;
import com.badlogic.gdx.graphics.g2d.TextureRegion;

public class MyGdxGame implements ApplicationListener {

SpriteBatch batch;
BitmapFont font;
Texture mario;





    @Override
    public void create() {
        mario = new Texture(Gdx.files.internal("mario.jpeg"));
        batch = new SpriteBatch();
        font = new BitmapFont();
        font.setColor(Color.CYAN);
    }

    @Override
    public void dispose() {
        batch.dispose();
        font.dispose();
    }

    @Override
    public void render() {      
        Gdx.gl.glClearColor(1, 1, 1, 1);
        Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);

        batch.begin();
        batch.draw(mario, 200, 200);
        batch.end();

    }

    @Override
    public void resize(int width, int height) {
    }

    @Override
    public void pause() {
    }

    @Override
    public void resume() {
    }
}

刚刚意识到出现了错误代码。文件名绝对正确。

Answer 1

引起：com.badlogic.gdx.utils.GdxRuntimeException：找不到文件：data / mario.png（内部）

在数据文件夹中找不到图像“mario.png”。确保您在android资源文件夹中有图像（Android项目 - ＆gt;资产 - ＆gt;数据 - ＆gt; mario.png）。

您可能想要了解如何阅读堆栈跟踪（Big long error report thing），它将为您节省大量时间。

Answer 2

Caused by: com.badlogic.gdx.utils.GdxRuntimeException: File not found: data/mario.png (Internal)

他找不到mario.png。如果您不使用Assets文件夹，我建议您创建包含所有资源的另一个源文件夹。之后，您可以调用Gdx.input.classpath(String classpath)从实际导出的.jar加载文件，而无需对路径进行硬编码。

libGDX仅编译黑屏
