what are you after? verification of it being possible? because it is.

I know it's possible, I just want to know the basics of how to do it.

Bump!

I have a single player mod that simply adds a clone of sugar cane, renamed to cocaine. It has 2 main classes:

mod_cocaine.java

package net.minecraft.src;
import java.util.Random;
public class mod_cocaine extends BaseMod {
  //Item / Block inits
  public static Block cocaPlant = (new BlockCocaPlant(200, ModLoader.addOverride("/terrain.png", "/winDev/CocaPlant.png"))).setHardness(0.0F).setResistance(0.0F).setBlockName("Coca Plant");
  public static final Item cocaLeaves = new Item(415).setItemName("Coca Leaves");
  public static final Item cocaPaste = new Item(416).setItemName("Coca Paste");
  public static final Item cocainePack = new ItemFood(417, 4, 0F, false).setPotionEffect(Potion.moveSpeed.id, 60, 0, 10F).setItemName("Cocaine Pack");
  static Achievement openInventory = AchievementList.openInventory;
  public static final Achievement cocainePackCraft = new Achievement(5000, "Drug Trafficker", 4, 9, mod_cocaine.cocainePack, openInventory).registerAchievement();
 
  public mod_cocaine()
		 {
		  
		   //Coca Plant (Block)
	 ModLoader.registerBlock(cocaPlant);
				 ModLoader.addName(cocaPlant, "Coca Plant");
				 ModLoader.addRecipe(new ItemStack(mod_cocaine.cocaPlant, 3), new Object[] {"#", Character.valueOf('#'), Block.dirt});
				
				 cocaLeaves.iconIndex = ModLoader.addOverride("/gui/items.png", "/winDev/cocaLeaves.png");
				 ModLoader.addName(cocaLeaves, "cocaLeaves");
				 ModLoader.addShapelessRecipe(new ItemStack(mod_cocaine.cocaLeaves, 4), new Object[] {new ItemStack(mod_cocaine.cocaPlant)});
				
				 cocaPaste.iconIndex = ModLoader.addOverride("/gui/items.png", "/winDev/cocaPaste.png");
				 ModLoader.addName(cocaPaste, "Coca Paste");
				 ModLoader.addShapelessRecipe(new ItemStack(mod_cocaine.cocaPaste, 1), new Object[] {new ItemStack(mod_cocaine.cocaLeaves), new ItemStack(Item.bucketWater), new ItemStack(Item.bowlEmpty)});
				
				 cocainePack.iconIndex = ModLoader.addOverride("/gui/items.png", "/winDev/cocainePack.png");
				 ModLoader.addName(cocainePack, "Cocaine Pack");
				 ModLoader.addRecipe(new ItemStack(mod_cocaine.cocainePack, 1), new Object[] {
				  "###", "#@#", "###", Character.valueOf('#'), Item.paper, Character.valueOf('@'), mod_cocaine.cocaPaste
				  });

I should also mention that I have almost no experience with SMP modding.

I want to make a new crop that acts like sugar cane but has different crop growing graphics and names. Does anyone have advice on how I would go about doing this or can point me to some resources?
Thanks!

Hi, I'm not sure if this is in the right section, but I need some help setting up my server.
I have two groups: A and B. I don't want Group A to be able to go into the Group B zone and vice versa. How would I be able to block the groups from certain areas in the map?

I am using Essentials Groupmanager for the groups and I also have WorldEdit and WorldGuard. How can I perform this?

Thanks!

Killer says he's working on it on the Forums. Don't worry about it, the server hasn't been hacked, it's only a problem with the permissions plugin.

Is the server down for anyone else now?

I hate to resurrect a dead post, but A TREE is singular which would mean one tree.
GRAMMAR NAZI, AWAY!

I just have a few recipes for a toolset, and when I attempt to run Minecraft from Eclipse it crashes with this:

P.S. This seems to happen any time I have more than one recipe. Am I doing something wrong?

Thanks in advance!

EDIT: I should have also included the work I did to the EnumToolMaterial File:

I would love Mac OSX support :c

Since some random time yesterday, my client has been acting very odd. When I click on anything when the game is resized from the original size (the size of the launcher), it either lags for around 2 seconds before registering my click, or it doesn't register at all (It's usually the latter). I have tried deleting my minecraft folder twice now. Also, I am on a Mac with a 23-inch monitor attached. It seems to lag even when the monitor is not plugged in though.

Is there anything I can do to fix this, and is this a known problem? All I can find is the double block placing glitch.

Quote from Gregorio246

try

RenderPig(new ModelPig(),new ModelPig(), 1.0F))

or

ModelPig model = new ModelPig();
RenderPig(model,model, 1.0F))

Thanks. I will try that ASAP and get back to you!

I am trying to create a Hog mob that uses the Pig model. Here is my EntityHog:

package net.minecraft.src;

import java.util.Random;

public class EntityHog extends EntityAnimal{
		Random r=new Random();

	public EntityHog(World world){
		super(world);
		texture = "/hog/hogMap.png";
		moveSpeed = 0.8F;
	}

	public int getMaxHealth(){
		return 20;
	}

	protected int func_40119_ar(){
		return 2;
	}

	public void onLivingUpdate(){
		super.onLivingUpdate();
	}

	protected String getLivingSound(){
		return "mob.pig";
	}

	protected String getHurtSound(){
		return "mob.pig";
	}

	protected String getDeathSound(){
		return "mob.pig";
	}

	protected int getDropItemId(){
		return r.nextInt(2)==0?Item.pickaxeStone.shiftedIndex:Item.stick.shiftedIndex;
	}

	public EnumCreatureAttribute func_40124_t(){
		return EnumCreatureAttribute.UNDEFINED;
	}
	public EntityAnimal spawnBabyAnimal(EntityAnimal entityanimal) {
				return new EntityHog(worldObj);
		}
}

And, my mod_Hog:

package net.minecraft.src;

import java.util.Map;

public class mod_Hog extends BaseMod{
		public mod_Hog(){


				ModLoader.registerEntityID(EntityHog.class, "Hog", ModLoader.getUniqueEntityId());
				ModLoader.addSpawn(EntityHog.class, 100, 1, 3, EnumCreatureType.creature);

		}


		public void addRenderer(Map map){
				map.put(EntityHog.class, new RenderPig(new ModelPig(), 1.0F)); <--- Error here.
		}


		public void load(){

		}
		public String getVersion(){
				return "1.2.5";
		}
}

The error Eclipse is giving is "The constructor RenderPig(ModelPig, float) is undefined".

Thanks!
