[1.7.10] Integrating Forge Multipart into mod [Help with Gradle]

Enkey · July 23, 2015

Hey everyone,

I'm making a simple mod which adds blocks and I want to make them cuttable into microblocks using Forge Multipart. From my research I found that all I need to do is register the blocks using MicroMaterialRegistry#registerMaterial, but I'm not sure if that is true.

1. Problem [sOLVED] (CCL must be downloaded manualy)

I can't make the needed mods (CodeChickenCore, ForgeMultipart) to work inside eclipse. I followed a tutorial and downloaded the dev and src jars and put the dev jars into folder /eclipse/mods/ and the src jars into /lib folder in eclipse. I ran the Client inside eclipse and the mods were there and it was working, but then I added the dev jars as libraries (Java Build Path > Libraries > Add JARs) so I can make the microblocks. I ran Client again and when it's loading mods it says that CodeChickenCore is duplicate ([Client thread/ERROR]: Found a duplicate mod CodeChickenCore at [minecraft.jar, minecraft.jar])

I also tried putting the dev jars in /lib folder and adding them as libraries, but then it crashed because it couldn't find the mods

2. Problem [sOLVED] (you have to register the materials in Init phase not PreInit)

Because I couldn't try the code in eclipse I built my mod into JAR and put it in a modpack with the needed mods (CodeChickenCore, ForgeMultipart) and it crashed because of NullPointerException

I tried to make it so it doesn't require the ForgeMultipart, but work with it when it's installed, and that is working well. Without any other mods it works great, but with ForgeMultipart it crashes.

Here is the important code:

Main Mod class:

public void preInit(FMLPreInitializationEvent event) {
	logger = event.getModLog();

	logger.info("Loading " + EnkeysBuildingBlocks.NAME + " version " + EnkeysBuildingBlocks.VERSION + ".");

	BlocksInit.init();

	if (Loader.isModLoaded("ForgeMultipart")){
		try {
			Class.forName("cz.enkey.enkeysbuildingblocks.multipart.MultipartRegistry").asSubclass(MultipartInterface.class).newInstance().init();
		} catch (InstantiationException e) {
			logger.error("Could not integrate Forge Multipart mod!");

			logger.error("Could not integrate Forge Multipart mod!");
			e.printStackTrace();
		} catch (ClassNotFoundException e) {
			logger.error("Could not integrate Forge Multipart mod!");
			e.printStackTrace();
		};
	}

	logger.info(EnkeysBuildingBlocks.NAME + " version " + EnkeysBuildingBlocks.VERSION + " loaded Phase 1 successfully!");
}
    
    @EventHandler
public void init(FMLInitializationEvent event) {
	logger.info("Loading " + EnkeysBuildingBlocks.NAME + " version " + EnkeysBuildingBlocks.VERSION + " Phase 2.");

	logger.info(EnkeysBuildingBlocks.NAME + " version " + EnkeysBuildingBlocks.VERSION + " loaded Phase 2 successfully!");
}

	logger.info(EnkeysBuildingBlocks.NAME + " version " + EnkeysBuildingBlocks.VERSION + " loaded Phase 3 successfully!");
}
}

BlocksInit.java

package cz.enkey.enkeysbuildingblocks.init;

	brick_wall = new BrickWall(); RegUtils.reg(brick_wall);
	metal_sheet_wall= new MetalSheetWall(); RegUtils.reg(metal_sheet_wall);
	concrete = new Concrete(); RegUtils.reg(concrete);
}
}

MultipartRegistry.java

package cz.enkey.enkeysbuildingblocks.multipart;

import codechicken.microblock.BlockMicroMaterial;
import codechicken.microblock.MicroMaterialRegistry;
import cz.enkey.enkeysbuildingblocks.init.BlocksInit;

public class MultipartRegistry implements MultipartInterface {

@Override
public void init(){
	MicroMaterialRegistry.registerMaterial(new BlockMicroMaterial(BlocksInit.brick_wall, 0), BlockMicroMaterial.materialKey(BlocksInit.brick_wall)); // here it crashes with NullPointerException (maybe brick_wall is null, but I am initializing it before this)
	MicroMaterialRegistry.registerMaterial(new BlockMicroMaterial(BlocksInit.metal_sheet_wall,0), BlockMicroMaterial.materialKey(BlocksInit.metal_sheet_wall));
	MicroMaterialRegistry.registerMaterial(new BlockMicroMaterial(BlocksInit.concrete,0), BlockMicroMaterial.materialKey(BlocksInit.concrete));
}
}

Any help is appriciated

Problem 1:

Duplicate mod error occurs only if you load mod twice. It can (and is) most likely occuring because you put the API into both /mods/ folder and add it as library to project.

What you need to do:

* When using mod as a library, do NOT put it into /mods/. You can put it ANYWHERE and then only thing you need is to reference it as library. When mod is declared as a library it will be loaded on startup and usable in your code.

Enkey · July 24, 2015

As I said I already tried that

I also tried putting the dev jars in /lib folder and adding them as libraries, but then it crashed because it couldn't find the mods

I've put it only in /lib and linked it as Library and it crashed like that. Not sure why is it crashing though, it should work even without the mods.

Enkey · July 24, 2015

Okay I fixed it now, I didn't know that CCC won't download CCL automaticaly when it's not in /mods folder so I downloaded CCL manualy and added it the same way.

Now I need to solve the second problem with the code. I don't know if I am doing it right, I just went trough Mekanism code to see how he's doing it. I tried to find some tutorial on it, but I only found tutorials for making custom microblocks, but I only need the normal ones (Cover, Panel, Slab, etc.)

Enkey · July 24, 2015

I fixed even the second problem. I had to register the materials in Init phase not PreInit *facepalm*

loordgek · July 24, 2015

why dont you use maven

	
maven { // the repo from which to get NEI and stuff 
		name 'CB Repo'
		url "http://chickenbones.net/maven/"
	}

	
        compile "codechicken:CodeChickenLib:1.7.10-1.1.3.138:dev"
compile "codechicken:CodeChickenCore:1.7.10-1.0.4.29:dev"
compile "codechicken:NotEnoughItems:1.7.10-1.0.3.74:dev"
compile "codechicken:ForgeMultipart:1.7.10-1.1.0.297:dev"

Enkey · July 24, 2015

I am new to gradle. How do I then use it as library?

Enkey · July 24, 2015

Thanks, that kinda worked, but it only downloaded CCL and ForgeMultipart

I added this to build.gradle

maven {
            name 'CB Repo'
            url "http://chickenbones.net/maven/"
        }

compile "codechicken:CodeChickenLib:1.7.10-1.1.3.140:dev"
    compile "codechicken:CodeChickenLib:1.7.10-1.1.3.140:src"
    compile "codechicken:CodeChickenCore:1.7.10-1.0.7.46:dev"
    compile "codechicken:CodeChickenCore:1.7.10-1.0.7.46:src"
    compile "codechicken:NotEnoughItems:1.7.10-1.0.5.111:dev"
    compile "codechicken:ForgeMultipart:1.7.10-1.1.0.297:dev"
    compile "codechicken:ForgeMultipart:1.7.10-1.1.0.297:src"

and even no errors occured during gradle dependency downloading

Choonster · July 24, 2015

Do you have CCC and NEI in your Eclipse project anyway or are they missing? They may have been already been downloaded.

Enkey · July 26, 2015

They are missing so I don't think they are downloaded
