問題描述

我嘗試學習 LibGDX，我安裝了列出的所有軟件 這里在新格式化的 mac OS X Maverick 上使用新的 Eclipse 4.3.

I trying to learn LibGDX, I install all the software listed here with a new Eclipse 4.3 on a fresh formatted mac OS X Maverick.

一切順利，重新啟動后，我下載并執行 gdx-setup.jar，填寫表格，然后導入 Eclipse.

Everything goes smooth, after a reboot, I download, and execute the gdx-setup.jar, fill the form, and import into Eclipse.

當我嘗試運行桌面時，沒有錯誤，沒有警告.(右鍵桌面項目，Run As -> Java Application).

No error, no warning, when I try to run the desktop. (Right click the desktop project, Run As -> Java Application).

我收到了這個錯誤

我在這里發現了很多類似的問題，我都嘗試了，但沒有任何好的結果...昨晚我發現了 這個，很酷，我有最新的 Java 1.8，一個 mac，和 Eclipse 完美契合...

I found a lot of similar issue here, I try them all without any good result... Last night I found this, very cool I have the latest Java 1.8, a mac, and Eclipse fit perfectly...

但沒有成功，我嘗試使用 Java 1.6 和 1.7，總是同樣的錯誤(未找到文件，我保留 Java 1.7)

But no success, I try with Java 1.6 and 1.7, Always the same error (No file found, I kept Java 1.7)

我開始做一些debug，這里我只修改導入生成的原始代碼.

I begin to do some debug, here my only modification of the original code generated by the importation.

package com.diesel.bugs;

import com.badlogic.gdx.ApplicationAdapter;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.graphics.GL20;
import com.badlogic.gdx.graphics.Texture;
import com.badlogic.gdx.graphics.g2d.SpriteBatch;

public class DieselBugs extends ApplicationAdapter {
    SpriteBatch batch;
    Texture imgExternal,imgLocal;

    @Override
    public void create () {
        batch = new SpriteBatch();
        String pathLocal = Gdx.files.getLocalStoragePath();
        String pathExternal = Gdx.files.getExternalStoragePath();
        Boolean isExternal = Gdx.files.isExternalStorageAvailable();
        Boolean isLocal = Gdx.files.isLocalStorageAvailable();
        imgExternal = new Texture(Gdx.files.external("/Desktop/badlogic.jpg"));
        imgLocal = new Texture(Gdx.files.local("badlogic.jpg")); 
    }

    @Override
    public void render () {
        Gdx.gl.glClearColor(1, 0, 0, 1);
        Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
        batch.begin();
        batch.draw(imgExternal, 0, 0);
        batch.end();
    }
}

奇怪的是 pathLocal 等于 "".Gdx.files.getLocalStoragePath() 什么都不返回(空字符串)正常嗎?

The weird thing is pathLocal is equal to "". Is it normal for Gdx.files.getLocalStoragePath() to return nothing (empty string)?

還有

imgExternal = new Texture(Gdx.files.external("/Desktop/badlogic.jpg"));

效果很好.只有本地的會報錯，isLocal也是，isExternal返回true.

Works great. only the local one gives the error, also isLocal, and isExternal return true.

我嘗試了很多組合，例如 /assets/data/badlogic.jpg、/assets/badlogic.jpg、/data/badlogic.jpg、data/badlogic.jpg 和 badlogic.jpg.

And I try a lots of combinations, like /assets/data/badlogic.jpg, /assets/badlogic.jpg, /data/badlogic.jpg, data/badlogic.jpg, and badlogic.jpg.

圖片 badlogic.jpg 在那里，我把它放在多個地方確定.

The image badlogic.jpg is there and I put it in multiple places to be sure.

現在我在這里尋求幫助的原因是我只是在 PC 上嘗試所有相同的步驟，一切都很好.

And now the reason why I'm here for help is I just try all the same step on a PC and everything works great.

我的新 Mac 及其設置有什么問題?

What is wrong with my new mac and it's setting?

當您運行桌面項目時

應用程序將在第一次失敗.打開剛剛創建的運行配置，將工作目錄設置為android/assets/目錄！

The application will fail the first time. Open the Run Configuration you just created and set the working directory to the android/assets/ directory!

將您的桌面項目鏈接到 android assets 文件夾?

link your desktop project to android assets folder?

轉到 Run => Run Configurations.. => 選擇 DesktopLauncher，Arguments Tab => Working Directory => Others 然后瀏覽到yourproject-android/assets/并點擊 Apply => Run

Go to Run => Run Configurations.. => choose DesktopLauncher, Arguments Tab => Working Directory => Others then browse to yourproject-android/assets/ and click Apply => Run
