Include external folders into minecrafts default resourcepack?[NEED HELP]

[ItsAMysteriousYT]

For my mod i want to give users the possibility to add in more stuff. I wrote a software that generates the required file structure, but for example i have to load some itemmodels which have to be in minecrafts default resource pack. Can anybody help me  with that?

You need to use implementation of IResourcePack. For this particular case you can use FileResourcePack that will allow you to load file as a resource pack.

 

You will need to put that resource pack into defaultResourcePacks in Minecraft.class (using reflection - note: use forge's reflection helper).

After adding it to list you need to refresh resources - to do that you simply call method which is also in Minecraft.class I think (#refreshResources?).

To find it you can look at Gui class of resource pack lists (which call it after changing pack)

[ItsAMysteriousYT]

Okay... I wrote some reflection stuff without the reflectonHelper. Is it used the right way?

 

 

private void loadCoreModules(){

try {

Class MinecraftClass = Minecraft.getMinecraft().getClass();

Field l = MinecraftClass.getDeclaredField("defaultResourcePacks");

l.setAccessible(true);

Class c = l.getClass();

if(c.getName()=="List"){

((List) c.cast(List.class)).add(new RLMPack());

}

System.out.println("Reflected:"+l);

}catch(Exception e){

e.printStackTrace();

}

}

 

 

And can you show me how to use reflectionHelper?

[Ernio]

 

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

defaultResourcePacks.add(new FileResourcePack(new File("C:/Users/My/Stuff/iAmRetarded/lol/hiddenMessage/pack.jar")));

Minecraft.getMinecraft().refreshResources();

 

In this example the pack.jar will be treated as LITERALLY normal resource pack (zip/jar) - so resource pack structure applies (assets/modid/textures/...etc).

Idk if there is direct implementation for normal "folders" (above is for .jar/.zips only, I belive), but if there is not - you can make one, easy stuff.

I remember that it is possible without reflection.

 

EDIT: Found it.

You can do that with this code:((SimpleReloadableResourceManager)Minecraft.getMinecraft().getResourceManager()).reloadResourcePack(IResourcePack)

[ItsAMysteriousYT]

Okay thank you. Ill try both methods. The IResourcePack is my File right?

[ItsAMysteriousYT]

Okay, im kinda struggling what to put into the IResourcePack file. I had a look at the minecraft defaultpack, but im not sure if theres anything missing.

 

Heres the FIle:

 

 

package itsamysterious.mods.reallifemod;

 

import java.awt.image.BufferedImage;

import java.io.File;

import java.io.FileInputStream;

import java.io.IOException;

import java.io.InputStream;

import java.util.Set;

 

import com.google.common.collect.ImmutableSet;

 

import net.minecraft.client.Minecraft;

import net.minecraft.client.resources.FolderResourcePack;

import net.minecraft.client.resources.IResourceManager;

import net.minecraft.client.resources.IResourceManagerReloadListener;

import net.minecraft.client.resources.IResourcePack;

import net.minecraft.client.resources.data.IMetadataSection;

import net.minecraft.client.resources.data.IMetadataSerializer;

import net.minecraft.util.ResourceLocation;

 

public class RLMPack extends FolderResourcePack implements IResourcePack,IResourceManagerReloadListener{

    public static final Set defaultResourceDomains = ImmutableSet.of("reallifemod");

 

public RLMPack() {

super(new File(Minecraft.getMinecraft().mcDataDir+"/RLM/"));

}

 

@Override

public InputStream getInputStream(ResourceLocation p_110590_1_) throws IOException {

return new FileInputStream(new File(Minecraft.getMinecraft().mcDataDir+"/RLM/"));

}

 

@Override

public boolean resourceExists(ResourceLocation p_110589_1_) {

return true;

}

 

@Override

public Set getResourceDomains() {

return defaultResourceDomains;

}

 

@Override

public IMetadataSection getPackMetadata(IMetadataSerializer p_135058_1_, String p_135058_2_) throws IOException {

return null;

}

 

@Override

public BufferedImage getPackImage() throws IOException {

return null;

}

 

@Override

public String getPackName() {

return "RLMPack";

}

 

@Override

public void onResourceManagerReload(IResourceManager resourceManager) {

}

}

Kay, the option with reflection worked perfect - thanks!!

[jabelar]

I remember that it is possible without reflection.

You can do that with this code:((SimpleReloadableResourceManager)Minecraft.getMinecraft().getResourceManager()).reloadResourcePack(IResourcePack)

 

Yeah, I was going to mention that. Ernio's approach is something that was described by diesieben07 a while back. But I've never understood why you needed reflection because the Minecraft#getResourceManager() returns an the IResourceManager publicly and further has public methods for getting resources. But diesieben07 usually knows more than the rest of us combined, so there is probably a reason he suggested it his way.

[ItsAMysteriousYT]

Okay, now im confused. The method i used with reflection is right or wrong? Cuz it works perfectly fine.

[ItsAMysteriousYT]

I mean this:

 

private void loadCoreModules(){

 

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

 

defaultResourcePacks.add(new FolderResourcePack(new File(Minecraft.getMinecraft().mcDataDir+"/RLM")));

 

Minecraft.getMinecraft().refreshResources();

}

[ItsAMysteriousYT]

Awesome thanks
