Press the "New Class" button. It is a green circle with a white 'c' on it. Then just type in the name of the class and the information below in the appropriate boxes.

Source Folder: Client/bin
Package: net.minecraft.src

What is line 228 of your mod_*** class? All I can tell you at the moment is that there is something wrong with one of your recipes. I can assist you further when you post that line. Please remember to use spoilers when posting long code.


Mod Development

Thx bro it was an empty character.valueof ("X") in line 229
p.s. how did you know it was line 228?

I know you said you didn't want any more suggestions but could you please add a tutorial on how to make blocks interact with Redstone current (I.e. Lamps, dispensers etc.)

thanks a ton

Does anyone know the name of the class that handles ore generation? I just want to have a look at it.

Thanks in advance!

Edit: Nevermind, ignore this question.

sorry if I sound dumb but I just started modding and was wondering if you needed to create a new "mod_" class every time you add something new. I.e. I want multiple blocks, would I need a "mod_desk", a "mod_table" and a "mod_chair" for three different items.

also was wondering if I just wanted to make 3 blocks that did the same thing but had different textures would I need separate "mod_" class's or just 3 different extensions of the one "mod_" class

thanks in advance.

no, it will make the game slower.

By the looks of it, (somehow) there are two classes/files with the same name.

While it may slow down the client slightly having multiple mod_ classes, it doesn't really matter. However, it makes it a lot easier to keep it all in one mod_ class.

Finally my mod is semi done!

TechGuy, How can I make my bipedal pigman (made with this tutorial) breedable. A guy suggested to change it to extend EntityAnimal I think and it works fine, but while they can mate, they won't produce a baby ever. (BTW extending it works well to add AI and such.)

Put this in your entity class, or just change the one you currently have to the same thing.

    public EntityAnimal spawnBabyAnimal(EntityAnimal par1EntityAnimal)
    {
        return new EntityPigman(worldObj);
    }

I can't fix this error I keep on getting from following the ore generation tutorial. In this line of code:



public void generateSurface(World world, Random random, int chunkX, int chunkZ)



The Random is a error for some reason, can someone help me please.

	}

It works wonders, only thing is that it makes a full-size entity instead of a baby and can't be distinguished from an adult. It still makes it well and makes them untameable until the 'baby' becomes an 'adult'Thanks anyways.

EDIT: do you think I could make an else statement on mob size for baby and adult?

You need to import Random.

import java.util.Random;

Put it under your package declaration at the top.

Make a duplicate of ModelBiped, then use this as the render method.

public void render(Entity par1Entity, float par2, float par3, float par4, float par5, float par6, float par7)
    {
        setRotationAngles(par2, par3, par4, par5, par6, par7);

        if (isChild)
        {
            float f = 2.0F;
            GL11.glPushMatrix();
            GL11.glTranslatef(0.0F, field_40331_g * par7, field_40332_n * par7);
            bipedHead.render(par7);
            GL11.glPopMatrix();
            GL11.glPushMatrix();
            GL11.glScalef(1.0F / f, 1.0F / f, 1.0F / f);
            GL11.glTranslatef(0.0F, 24F * par7, 0.0F);
            bipedBody.render(par7);
            bipedLeftLeg.render(par7);
            bipedRightLeg.render(par7);

            GL11.glPopMatrix();
        }
        else
        {
            bipedHead.render(par7);
            bipedBody.render(par7);
            bipedLeftLeg.render(par7);
            bipedRightLeg.render(par7);
        }

	}

when I make the duplicate, do I have to change the entity file as well to use it?

EDIT:I also get an error on the line

GL11.glTranslatef(0.0F, field_40331_g * par7, field_40332_n * par7);

Multiple markers at this line
- field_40331_g cannot be resolved to a
variable
- field_40332_n cannot be resolved to a
variable

Yes, you must call the new model class, in the addRenderer method in your mod_** class. You will probably have to make a new render class as well, to suit your new Model*** class. Add these in to your model class:

	protected float field_40331_g;
	protected float field_40332_n;

I get an error when i try to mine my ore. ! I did everything you did in Ore generation. and theres no errors. and i can recompile. and see the ore. But when i place it down or mine it . the game crash. heres the report


EDIT:It was the Sound code. I added a sound footstep on it and that was what the problem were

Quote from Blaueseichoern

Well , maybe it's too easy , so nobody ever have written something about it ,but I haven't found something yet.
So , does anybody know how to load a self-created mod out of the "mods"-folder with Modloader?

Put all your mod files in a zip file, and then place the zip in your mods folder. You may have to use a third-party archive program, as the one's that come with the OS do not always work.

Quote from Jakesansby

Please help i want to use my own item's to create a block but it is not working.

Code for Block

ModLoader.addRecipe(new ItemStack(LightGold, 1), new Object [] {"###", "#*#", "###", Character.valueOf('#'), StrongGold, Character.valueOf('*'), GoldPowder});

Code for StrongGold

public static final Item StrongGold = new ItemStrongGold(2001).setItemName("StrongGold");

Code for Gold Powder

public static final Item GoldPowder = new ItemGoldPowder(2000).setItemName("GoldPowder");

Please reply a pm would be nice but if not just on here please
Thanks loads

What is not working? Please post your error report, and ALL of your code.
