Hello there :)

 

I wanted to use the new "modder" version of forge and play around with it. Everything seems to work, but I have issues with entities: If I use only the method ModLoader.registerEntityID(...) and spawn the entity ingame, I can hear them, but I can't see them. Also I cannot kill them, except they manage to kill themselves (e.g. lava / falling sand). If they die, sometimes I get this error:

 

java.util.ConcurrentModificationException

--- END ERROR REPORT 7cb8184b ----------

 

 

So I searched in the forge code and found this method:

EntityRegistry.registerModEntity(CSM_EntityClayMan.class, "CSM_EntityClayMan", 0, this, 64, 1, true);

If I use this method and spawn the entity in a new world, I got an error which says "Disconnected by Server: Internal Server error" with no detailed information. If I try to open that world again, it crashes with following error:

So apparently I'm doing something wrong, but I can't figure out what.

 

This is how my mod_ class looks like now:

 

package net.minecraft.src;

 

import cpw.mods.fml.common.network.NetworkMod;

import cpw.mods.fml.common.registry.EntityRegistry;

 

import net.minecraftforge.client.MinecraftForgeClient;

import net.minecraftforge.common.MinecraftForge;

 

@NetworkMod

public class mod_ClayMan extends BaseMod {

 

public String getVersion() {

        return "1.2.5 v.7.9";

    }

 

  /* some items here */

 

    public static String modName = "ClaySoldierMod";

    public static final String textureFile = "/claymans/CSMItems.png";

   

  /*some item IDs here */

   

    private static void setIDs() {

    SAP_ConfigManager cfg = new SAP_ConfigManager("Clay Soldiers Mod", "1.1");

   

    cfg.setVar_IN_A(itemNames, itemIDs, cfg.getGroupIdFromName("Item IDs"));

   

    cfg.loadConfig();

   

    itemIDs = cfg.getVar_IN_A(itemNames);

    }

 

    public mod_ClayMan() {

 

    }

 

@Override

public void load() {

 

setIDs();

 

ModLoader.setInGameHook(this, true, true);

MinecraftForgeClient.preloadTexture(textureFile);

 

/* some item initializations */

 

ModLoader.registerEntityID(CSM_EntityClayMan.class, "CSM_ClaySoldier", ModLoader.getUniqueEntityId());

EntityRegistry.registerModEntity(CSM_EntityClayMan.class, "CSM_ClaySoldierMP", 0, this, 64, 1, true);

 

/* some more of that above for other entities */

 

/* some recipes */

}

 

@Override

public boolean onTickInGame(float f, Minecraft game) {

/* moar code */

}

 

 

@Override

    public void addRenderer(Map map) {

        map.put(CSM_EntityClayMan.class, new CSM_RenderClayMan(new CSM_ModelClayMan(0F, 13F), 0.125F));

/*some more of that above for other entities */

    }

 

@Override

public boolean dispenseEntity(World world, double x, double y, double z, int xVel, int zVel, ItemStack item) {

/*some dispensing stuff */

}

}

 

 

 

BTW: all the entities are basically extending EntityCreature.

 

 

I hope you can help me with that. Thanks in advance.

This thread makes me sad because people just post copy-paste-ready code when it's obvious that the OP has little to no programming experience. This is not how learning works.

I use both, but it doesn't work either :/

 

It's the same error I get as when I use only EntityRegistry.registerModEntity.

Sorry for DP, but I searched in the code again for a solution, rewrote my mod_ file to the new Forge system and stuff. I found out that I have to implement IAnimals now for my entities. I did that and somehow the entity is now registered. But as soon as I load a world with my entities or try to spawn them, I get this two errors together:

So I tried to catch these exceptions in the Render file with try { ... } catch (NullPointerException e {} blocks. Then tried to open the world with my entities and I see my entities will be rendered now, but with "vanilla" textures like Creeper and spiders and even some with the /gui/items.png as texture, as seen here:

 

jx6h0.png

 

 

As soon as I try to kill any of them, I get this error:

So either I forgot something again or this is a forge bug. Here is my changed mod_* file:

https://gist.github.com/4e3d7b2b13bb339601b7

 

Is there a way to solve this? :/

 

 

EDIT: forgot to insert screen

 

EDIT 2: If I outcomment the call super.onLivingUpdate() in my CSM_EntityClayMan class, I get this error, which is similar to that last one above:
