Just wondering how you make a tools, in my case a hoe do more then just the 1 block it would normally do, e.g I want my hoe to farm a 3x3 area just on 1 click. hope someone can help.

 

My hoe code:

package magicCrop;

import net.minecraft.creativetab.CreativeTabs;
import net.minecraft.item.EnumRarity;
import net.minecraft.item.EnumToolMaterial;
import net.minecraft.item.ItemHoe;
import net.minecraft.item.ItemStack;
import cpw.mods.fml.relauncher.Side;
import cpw.mods.fml.relauncher.SideOnly;

public class MagicHoe extends ItemHoe {
public MagicHoe(int ItemID, EnumToolMaterial material){
	super(ItemID, material);
	this.maxStackSize = 1;
	this.setCreativeTab(CreativeTabs.tabTools);
}

public String getTextureFile(){
	return "/magiccrops/crops.png";
}

@SideOnly(Side.CLIENT)
public EnumRarity getRarity(ItemStack par2){
	return EnumRarity.epic;
}
}

1 second i think i got it working its easy

 

I think this should work:

 

package kaiKaii99Items;

    {
        super(par1);
        this.theToolMaterial = par2EnumToolMaterial;
        this.maxStackSize = 1;
        this.setMaxDamage(par2EnumToolMaterial.getMaxUses());
        this.setCreativeTab(CreativeTabs.tabTools);
    }

just make an item that extens SpecialItemHoe and done

I think, what you gonna do is override onItemUse in your MagicHoe class:

@Override
public boolean onItemUse(ItemStack par1ItemStack, EntityPlayer par2EntityPlayer, World par3World, int par4, int par5, int par6, int par7, float par8, float par9, float par10){
        if (!par2EntityPlayer.canPlayerEdit(par4, par5, par6, par7, par1ItemStack)){
            return false;
        }else{
            UseHoeEvent event = new UseHoeEvent(par2EntityPlayer, par1ItemStack, par3World, par4, par5, par6);
            if (MinecraftForge.EVENT_BUS.post(event)){
                return false;
            }

            if (event.getResult() == Result.ALLOW){
                par1ItemStack.damageItem(1, par2EntityPlayer);
                return true;
            }
            for(int i = -1; i < 2; i++){
            	for(int j = -1; j < 2; j++){
            		int i1 = par3World.getBlockId(par4+j, par5, par6+i);
            		int j1 = par3World.getBlockId(par4+j, par5 + 1, par6+i);

            		if (!((par7 == 0 || j1 != 0 || i1 != Block.grass.blockID) && i1 != Block.dirt.blockID)){
            			Block block = Block.tilledField;
            			par3World.playSoundEffect((double)((float)par4 + j + 0.5F), 
                                             (double)((float)par5 + 0.5F), (double)((float)par6 + j + 0.5F), block.stepSound.getStepSound(), 
                                             block.stepSound.getVolume() + 1.0F) /2.0F, block.stepSound.getPitch() * 0.8F);
            			if (!par3World.isRemote){
            				par3World.setBlock(par4 + j, par5, par6 + i, Block.tilledField.blockID);
            			}
            		}
            	}
            }
            par1ItemStack.damageItem(1, par2EntityPlayer);
            return true;
        }
    }

kaikaii99, your code is extremely bulky and unoptimized...

And why should he create a new class and extend his MagicHoe with it, when he can just add that one method (sic!) that does the work, to his own class?

1st, it's bulky because i didn't write the most of it, i just edited the itemhoe class, which its obvious. 2nd, Of course its unoptimized, i wrote it as an example, you can just write 1 simple for loop and its done, 3rd maybe he wants to make more 'magic' hoes, its easier if you just extend your class to the MagicHoe class

i wrote it as an example

You haven't said it was example, you wrote that and said "use it"...
