Trouble loading .png file using LibGDX Gdx.files.internal
提问by KaptnKrunch
I'm trying to load a Texture to libGDX and I'm getting a file not found exception.
我正在尝试将纹理加载到 libGDX，但出现文件未找到异常。
Here's the code that's trying to load the .png file.
这是尝试加载 .png 文件的代码。
//Textures
private Texture tiles;
private TextureRegion grassImage;
private TextureRegion dirtImage;
private TextureRegion stoneImage;
//Entities
private Texture entities;
private TextureRegion playerImage;
public WorldRenderer(World world, boolean debug) {
this.world = world;
this.camera = new OrthographicCamera(CAMERA_WIDTH, CAMERA_HEIGHT);
this.camera.position.set(CAMERA_WIDTH/2f, CAMERA_HEIGHT/2f, 0);
this.camera.update();
this.debug = debug;
spriteBatch = new SpriteBatch();
loadTextures();
}
public void loadTextures() {
tiles = new Texture(Gdx.files.internal("tiles.png"));
grassImage = new TextureRegion(tiles, 0, 0, 32, 32);
dirtImage = new TextureRegion(tiles, 0, 64, 32, 32);
stoneImage = new TextureRegion(tiles, 64, 0, 32, 32);
entities = new Texture(Gdx.files.internal("entities.png"));
playerImage = new TextureRegion(entities, 0, 0, 32, 32);
}
public void render() {
spriteBatch.begin();
drawGrass();
drawDirt();
drawStone();
drawPlayer();
spriteBatch.end();
if (debug) {
drawDebug();
}
}
Here's the error message:
这是错误消息：

The problem exists in the loadTextures() method. Can't find the file
问题存在于 loadTextures() 方法中。找不到文件
tiles = new Texture(Gdx.files.internal("tiles.png"));
I've made sure to put the .png files in the assets folder of the android project files. I have no idea what's causing this; I've gotten this to work on other projects but this time around something went awry. Thanks for any help.
我确保将 .png 文件放在 android 项目文件的资产文件夹中。我不知道是什么原因造成的；我已经将它用于其他项目，但这次出了点问题。谢谢你的帮助。

Solving the "Couldn't load file" issue by cleaning the project (Eclipse)
通过清理项目解决“无法加载文件”问题（Eclipse）
(For this solution is expected that the paths to your image files are correct.)
（对于此解决方案，您的图像文件的路径应该是正确的。）
Sometimes I have this Couldn't load fileproblem when I add new images to my project. I don't know why, but my Desktop version of my LibGDX game doesn't update the folder Mygame-desktop/bin/datawith my new images (which were added to Mygame-android/assets/data) when the project is built. (That is, every time I save a file, Eclipse builds the project, cause I set the option Project > Build Automatically.)
有时，当我将新图像添加到我的项目时，我会遇到无法加载文件的问题。我不知道为什么，但是我的 LibGDX 游戏的桌面版本在项目构建时没有使用我的新图像（已添加到Mygame-android/assets/data）更新文件夹Mygame-desktop/bin/data. （也就是说，每次我保存文件时，Eclipse 都会构建项目，因为我设置了选项Project > Build Automatically。）
It should work, cause in LibGDX the Desktop and HTML projects have a link to the Android project assets folder. So, I was not suppose to need to copy manually my new images to Mygame-desktop/bin/data.
它应该可以工作，因为在 LibGDX 中，桌面和 HTML 项目有一个指向 Android 项目资产文件夹的链接。因此，我不认为需要将我的新图像手动复制到Mygame-desktop/bin/data。
The solution, on Eclipse, is to clean (menu Project > Clean...) all LibGDX projects you use for your game, then the files in Mygame-android/assets/datawill be copied to Mygame-desktop/bin/dataproperly.
该解决方案，Eclipse的，是干净的（菜单项目>清洁...），你用你的游戏中所有LibGDX项目，然后将文件在Mygame-的Android /资产/数据将被复制到Mygame桌面/斌/数据正确.

Make a data folder in the assets folder and instead of using
在资产文件夹中创建一个数据文件夹，而不是使用
tiles = new Texture(Gdx.files.internal("tiles.png"));
try this:
尝试这个：
tiles = new Texture("data/tiles.png");

create new folder datain the assets folder of the android project and then access the file using Gdx.files.internal("data/tiles.png")
在android项目的assets文件夹中新建文件夹data，然后使用Gdx.files.internal("data/tiles.png")访问该文件
tiles = new Texture(Gdx.files.internal("data/tiles.png"));
tiles = new Texture(Gdx.files.internal("data/tiles.png"));

If you're using Gradle, click the left mouse button in package explorer on Aassets -> Gradle -> Refresh All.
如果您使用的是 Gradle，请在包资源管理器中单击鼠标左键 Aassets -> Gradle -> Refresh All.
That's it =)
就是这样=)

Click the left mouse button in Package Explorer on Refresh or just F5.

I have this issue working in android studio 2 using the current libgdx version. When I save as a png in psp - cs6 and/or cs15 - it can't read it. I can't recall the exact error message, something like io can't read stream. So I tried saving it again in corel paint. Same problem. Then with the simple paint utility packaged with windows. No good. Finally I downloaded paint.net. Now my workflow just involves an extra step. Any png generated with psp, etc., pretty much any png libgdx grumps about, I load into paint.net, hit "save" and I'm good to go.
我在使用当前 libgdx 版本的 android studio 2 中遇到了这个问题。当我在 psp - cs6 和/或 cs15 中保存为 png 时 - 它无法读取它。我不记得确切的错误消息，比如 io 无法读取流。所以我尝试在 Corel Paint 中再次保存它。同样的问题。然后使用 Windows 打包的简单绘图实用程序。不好。最后我下载了paint.net。现在我的工作流程只涉及一个额外的步骤。任何用 psp 等生成的 png，几乎所有 png libgdx 都发脾气，我加载到paint.net，点击“保存”，我很高兴。
Not really a solution per se, but gets the job done.
本身并不是真正的解决方案，但可以完成工作。
Looks like you're good but I hope this helps someone out there. Marc
看起来你很好，但我希望这可以帮助那里的人。马克

Maybe your PNG profile is not supported by LibGDX.
也许 LibGDX 不支持您的 PNG 配置文件。
I set it to sRGB-elle-V2-srgbtrc.icc(with Krita) and now it works.
我将它设置为sRGB-elle-V2-srgbtrc.icc（使用 Krita），现在它可以工作了。
In Krita go to:
在 Krita 中访问：
Image > Properties > Profile
图像 > 属性 > 配置文件
