That may be your opinion, but I have a separate program to view the minecraft classes. On an unrelated note, I fixed my problem and have a new error.

Why?

Hey Techguy, I followed your steps in making a mob hold something, but your tutorial said it is set up for renderbiped.class. My mob isn't biped, so how can I make it work?

I'm having some issues related to creating a new Fishing Rod.
I made a new class ItemFishingRod, but then when I enter the game and make the Rod, I can swing it but the fishing hook does not appear.

Hello, I'm working on a mod called ArcadiaCraft with Nickelordzero.

I've tried to add armor (this isn't on your page, so maybe you can't help).

MCP?! who said I was using mcp? all it's done is get in the way. eclipse already compiled some of my files, so I know the coder pack can't be the only way.

Quote from TechGuy543

Look at the textures section.


Post your code.


Post your render class.

I'm only going to help people using MCP. If someone can't get it to work without using MCP, then they should be using it.

package net.minecraft.src;
import org.lwjgl.opengl.GL11;
public class RenderCentaur extends RenderLiving
{
		protected ModelCentaur modelNamehereMain;
		protected float field_40296_d;
		public RenderCentaur(ModelCentaur par1ModelNamehere, float par2)
		{
				this(par1ModelNamehere, par2, 1.0F);
				modelNamehereMain = par1ModelNamehere;
		}
		public RenderCentaur(ModelCentaur par1ModelNamehere, float par2, float par3)
		{
				super(par1ModelNamehere, par2);
				modelNamehereMain = par1ModelNamehere;
				field_40296_d = par3;
		}
}

Here's my render class. Take note I only copied your code in the tut because you haven't explained anything about it yet.

package net.minecraft.src;
import org.lwjgl.opengl.GL11;
public class RenderCentaur extends RenderLiving
{
		protected ModelCentaur modelNamehereMain;
		protected float field_40296_d;
		public RenderCentaur(ModelCentaur par1ModelNamehere, float par2)
		{
				this(par1ModelNamehere, par2, 1.0F);
				modelNamehereMain = par1ModelNamehere;
		}
		public RenderCentaur(ModelCentaur par1ModelNamehere, float par2, float par3)
		{
				super(par1ModelNamehere, par2);
				modelNamehereMain = par1ModelNamehere;
				field_40296_d = par3;
		}
}

EDIT: Sorry, I didn't know how to make spoilers.

modelBipedMain.bipedRightArm.postRender(0.0625F);

modelNamehereMain.rightArm/*<--change that to whatever the name of the shape of the right arm is in the model class.*/.postRender(0.0625F);

Quote from TechGuy543

Add the renderEquippedItems method from ModelBiped to your code. Make sure you change this line, to reference to the correct part of your mob model.

modelBipedMain.bipedRightArm.postRender(0.0625F);

->

modelNamehereMain.rightArm/*<--change that to whatever the name of the shape of the right arm is in the model class.*/.postRender(0.0625F);

If you aren't sure what it is called, post your model class please.

If the above doesn't work then I can't help you, sorry.

Quote from Gamerzwin

Once you create the mod_ file where do u put it before you recompile and the textures??

Quote from DaSnipeKid

Okay so i just made a "Block" and i generated it in the world. Everything is going well except for 1 thing, i am able to mine the block with every pickax, how do i make it so that i can only mine it with a stone pick?

Quote from EscTheMiner

Also, can I have Multiple Potion Effects?

Quote from Xinito95

hey,

if EnumCreatureType is on .creature my mob have a texure but when I change .creature to .monster so they only spawn in the darkess my mob have no texture. also i've found a monsterspawner with my mob but they spawn white looking guys with a G on there head and not the texture I gave them.

please help me out i'm kinda confused how to fix the texture for .monster

ModLoader.addSpawn(EntityNamehere.class, 15, 5, 7, EnumCreatureType.creature);

Quote from MICHAELNESS

My question was never answered, so I'm going to ask it again. How can I make an already existing mob spawn more or spawn less. Hopefully doing it with the least amount of editing files or none if possible.

spawnableMonsterList.add(new SpawnListEntry(net.minecraft.src.EntityZombie.class, 10, 4, 4));

Quote from MICHAELNESS

Alright, I found that line of code.

spawnableMonsterList.add(new SpawnListEntry(net.minecraft.src.EntityZombie.class, 10, 4, 4));

but what do I change to change the spawn rate? :l
