无法通过AssetManager - libgdx从zip存档加载TextureAtlas [英] Couldn't load TextureAtlas from zip archive via AssetManager - libgdx
问题描述
我有2个AssetManager实例:一个用于基本纹理,一个用于高质量纹理。基本纹理位于android / assets文件夹中,高质量纹理包装在zip文件中。这个文件夹中的内容(文件名)是相同的 - 在zip存档中只有更好的质量纹理。
I have 2 instances of AssetManager: one for basic textures and one for high quality textures. Basic textures are located in "android/assets" folder and high quality textures are packed in zip file. Content (file names) in this folders are the same - there are only better quality textures in zip archive.
AssetManager抛出异常:无法加载资产的依赖关系:teamLogo.png当我试图从zip文件加载TextureAtlas时。当我加载纹理文件时一切正常。加载TextureAtlas仅适用于'android / assets'文件夹。
AssetManager throws an exception: "Couldn't load dependencies of asset: teamLogo.png" when I'm trying to load TextureAtlas from zip file. When I'm loading Texture file everything is ok. Loading TextureAtlas works only from 'android/assets' folder.
使用'android / assets'的AssetManager - 一切正常:
AssetManager using 'android/assets' - everything is ok:
AssetManager am = new AssetManager();
am.load( "images/image.png", Texture.class );
am.load( "images/teamLogo.pack", TextureAtlas.class );
使用zip存档的AssetManager - 无法加载TextureAtlas:
AssetManager using zip archive - can't load TextureAtlas:
ZipFile archive = new ZipFile(expansionFileHandle.file());
ArchiveFileHandleResolver resolver = new ArchiveFileHandleResolver(archive);
AssetManager amHQ = new AssetManager(resolver);
这样可行:
amHQ.load( "images/image.png", Texture.class );
这不起作用:
amHQ.load( "images/teamLogo.pack", TextureAtlas.class );
ArchiveFileHandle类:
ArchiveFileHandle class:
public class ArchiveFileHandle extends FileHandle
{
final ZipFile archive;
final ZipEntry archiveEntry;
public ArchiveFileHandle (ZipFile archive, File file)
{
super(file, FileType.Classpath);
this.archive = archive;
archiveEntry = this.archive.getEntry(file.getPath());
}
public ArchiveFileHandle (ZipFile archive, String fileName)
{
super(fileName.replace('\\', '/'), FileType.Classpath);
this.archive = archive;
this.archiveEntry = archive.getEntry(fileName.replace('\\', '/'));
}
@Override
public FileHandle child (String name)
{
name = name.replace('\\', '/');
if (file.getPath().length() == 0)
return new ArchiveFileHandle(archive, new File(name));
return new ArchiveFileHandle(archive, new File(file, name));
}
@Override
public FileHandle sibling (String name)
{
name = name.replace('\\', '/');
if (file.getPath().length() == 0)
throw new GdxRuntimeException("Cannot get the sibling of the root.");
return new ArchiveFileHandle(archive, new File(file.getParent(), name));
}
@Override
public FileHandle parent ()
{
File parent = file.getParentFile();
if (parent == null)
{
if (type == FileType.Absolute)
parent = new File("/");
else
parent = new File("");
}
return new ArchiveFileHandle(archive, parent);
}
@Override
public InputStream read ()
{
try
{
return archive.getInputStream(archiveEntry);
}
catch (IOException e)
{
throw new GdxRuntimeException("File not found: " + file + " (Archive)");
}
}
@Override
public boolean exists()
{
return archiveEntry != null;
}
@Override
public long length ()
{
return archiveEntry.getSize();
}
@Override
public long lastModified ()
{
return archiveEntry.getTime();
}
我做错了什么?
推荐答案
Yeaaahhh,我发现了它:) ArchiveFileHandle无法加载TextureAtlas的依赖项,因为他无法找到这些文件。查看zip存档时,您必须将'\'字符替换为'/'。该错误发生在ArchiveFileHandle构造函数之一。这一行:
Yeaaahhh, I found it :) ArchiveFileHandle couldn't load dependencies of TextureAtlas because he can't find those files. When looking in zip archive you have to replace '\' char to '/'. The bug was in one of ArchiveFileHandle constructors. This line:
archiveEntry = this.archive.getEntry(file.getPath());
应为:
archiveEntry = this.archive.getEntry(file.getPath().replace('\\', '/'));
现在一切正常
