So some might remember I am loading skills from external skill.jar files in runtime using modClassLoader. Now i'd like to also load resources placed there, how could I archieve this?

ResourceLoacetion allows me to only make modid:path.

To be more precise:

public static Skill loadSkill(File file)
{
	JarFile jarFile = null;
	try
	{
		jarFile = new JarFile(file);
		Enumeration<JarEntry> entries = jarFile.entries();

		while (entries.hasMoreElements())
		{
			JarEntry element = entries.nextElement();
			String name = element.getName();

			if (name.endsWith(".png"))
			{
				resourceMap.put(name, new ResourceLocation(***element I just read***);
				//above is an example, I will be obviously storing resources to more advanced holders.
			.....

How do I make something like it work?

I honestly have very little idea on how to work with it. ;/

 

I don't quite understand the logic behind resource management.

 

List<IResourcePack> defaultResourcePacks = ObfuscationReflectionHelper.getPrivateValue(Minecraft.class, Minecraft.getMinecraft(), "defaultResourcePacks", "field_110449_ao");

 

This gives me the list and then I can:

defaultResourcePacks.add(new MyIResourcePackImplementation())

 

But then what?

For what I am aware (from vanilla) - whenever you want to add resource to game you have to realod resources.

So i am assuming:

1. Load all Skill.jar

2. Get all .png files and save them in Map<String, File>

3. Create new MyIResourcePackImplementation(Map<String, File>)

4. Put MyIResourcePackImplementation into defaultResourcePacks using reflection code above.

 

Do I need to actually create new MyIResourcePackImplementation everytime or can I simply make this object once and put there files one by one?

 

Any neat explanation is appreciated. Just so I can get what is really happening there.

 

Edit: Also - does MC store all resources as simple directory link and use them from HDD? In that case wouldn't I need to copy files from .jar to some non-zipped dir first (to not open infinite number of JarFiles)?

 

FileResourcePack answers my Edit concerns (close() of zip).

 

I have literally no idea what am I doing.

 

public static void init()
{	
	List<IResourcePack> defaultResourcePacks = ObfuscationReflectionHelper.getPrivateValue(Minecraft.class, Minecraft.getMinecraft(), "defaultResourcePacks", "field_110449_ao");

	defaultResourcePacks.add(new SkillResourcePack(new File("C:/Users/Ernio/git/roa/RoA/Skills/SkillFireball.jar")));
}

 

For one I know:

[23:02:55] [Client thread/WARN]: Unable to parse metadata section of resourcepack: SkillFireball

That it is somewhat working.

 

File structure:

-SkillFireball.jar

--com

----packages.with.code

--assets

----fireball.png

 

How can I work it so:

private static ResourceLocation fireball = new ResourceLocation("something:fireball");

Will work? (or actually anything that is ResourceLoction will work).

 

I just dont understand relations there.

 

Sorry for questions, but this is first time I actually can't understand it on my own (trying) ;c

I am still missing something. I'll try to explain best I can.

 

 

1 - How asset would look like if it would be loaded by mod itself.

2 - The Skill.jar location that is being dynamically class-loaded AND which contains assets required by this skill.

3 - How Skill.jar looks inside (assets).

 

Now since, as you told me, if I'd put virtual IResourcePack (SkillFireball.jar in this case) into defaultResourcePacks, it should start working:

List<IResourcePack> defaultResourcePacks = ObfuscationReflectionHelper.getPrivateValue(Minecraft.class, Minecraft.getMinecraft(), "defaultResourcePacks", "field_110449_ao");
	defaultResourcePacks.add(new SkillResourcePack(new File("C:/Users/Ernio/git/roa/RoA/Skills/SkillFireball.jar")));

 

But as far as I know (I am SURE OF IT) before I attempt on doing this:

ResourceLocation fireball = new ResourceLocation(InitUtil.ModID + ":" + "textures/skills/Fireball.png");

 

I need to actually LOAD (refresh) resources, becaouse if I don't I will get this:

[23:53:49] [Client thread/WARN]: Failed to load texture: roa:textures/skills/Fireball.png
java.io.FileNotFoundException: roa:textures/skills/Fireball.png

at net.minecraft.client.renderer.texture.SimpleTexture.loadTexture(SimpleTexture.java:34) ~[simpleTexture.class:?]
.........

 

Now - how do I do that? That is what is bugging me. Next reply will probably solve this thread or cause me to rage quit and go to sleep, in any case - thank you

 

Note: I am not saying I wasn't alredy looking how MC loads resourcepacks, but that is being done on /resourcepacks/ directory.

The only way I noticed is to make use of this: this.mcResourceManager.reloadResources(arraylist); where array is list of all resourcepacks. Is this the right way? (do I have to reload whole game-resources to get mine working)

Oh my god, yes! For whole hour I've been getting closer to total rage, then I noticed:

new ResourceLocation(InitUtil.ModID + ":" + "textures/skills/Fireball.png"));
new ResourceLocation(InitUtil.ModID + ":" + "textures/skills/fireball.png"));

My face .__.

 

Thanks, thread closed

Question doesn't deserve whole thread and is not even Forge i think:

 

What happens if I'd load 2 virtual texturepacks that have one "same" element.

Which one takes priority? Last loaded? (I don't see LinkedMaps or Sets, so idk which one will be "last")
