Ello,

I have been updating a mod of mine recently, and it's almost done, however when I recompile the mod, reobufscate it and try to run in in minecraft, it fails with the following error:

Here is my Code for the BlockPlant file:

package moDrinks.common;

import java.util.Random;

import net.minecraft.src.Block;
import net.minecraft.src.BlockFlower;
import net.minecraft.src.CreativeTabs;
import net.minecraft.src.Material;
import net.minecraft.src.World;
import net.minecraftforge.common.IPlantable;

public class BlockPlant extends BlockFlower implements IPlantable
{	
//Main
protected BlockPlant(int par1, int par2, Material par3Material)
{
	super(par1 + 256, par2, par3Material);
	this.blockIndexInTexture = par2;
	this.setTickRandomly(true);
	float var4 = 0.4F;
        this.setBlockBounds(0.5F - var4, 0.0F, 0.5F - var4, 0.5F + var4, var4 * 2.5F, 0.5F + var4);
	this.setCreativeTab(CreativeTabs.tabDecorations);
}	
protected BlockPlant(int par1, int par2)
{
	this(par1, par2, Material.plants);
}

//Can be on
protected boolean canThisPlantGrowOnThisBlockID(int par1)
{
	return par1 == Block.grass.blockID || par1 == Block.dirt.blockID;
}
        public String getTextureFile()
        {
	return "/Eastonium/MoDrinksBlocks.png";
}
}

 

Please let me know if you can help!

You didn't reobfuscate properly.

 

In eclipse, copy all your package files into the 'Minecraft' project (into either the common folder or the src folder),

and THEN run recompile and reobfuscated. Your working mod will be outputted into rebof/minecraft

Could you please explain better? I tried to do what you said and i just resulted in me having to re-create MCP.
