I may have missed some think and just been really blind to something in the code but I am having a problem were I can create a new item fine and add it to the game all works fine but when i go to add a basic block minecraft loads but when i open a world existing or new it crashes.

 

I can Add what ever code is need to help me with this if anyone has an idea about this.

Thank you 

this is the block class

package green.mods.lapfuel.Blocks;

import green.mods.lapfuel.lib.BlockIDs;
import green.mods.lapfuel.lib.Strings;
import net.minecraft.block.Block;
import net.minecraft.block.material.Material;
import net.minecraft.client.renderer.texture.IconRegister;
import net.minecraft.creativetab.CreativeTabs;

public class LapronBlock extends Block {

public LapronBlock(int id){
	super(BlockIDs.LAPRON_BLOCK, Material.rock);
	this.setResistance(3F);
	this.setCreativeTab(CreativeTabs.tabBlock);
	this.setUnlocalizedName(Strings.LAPRON_BLOCK_NAME);


}
public void registerIcons(IconRegister iconRegister)
{
         blockIcon = iconRegister.registerIcon("LapronBlock");
}

}

 

 

This is the code for the mod Blocks class

package green.mods.lapfuel.Blocks;

import cpw.mods.fml.common.registry.GameRegistry;
import cpw.mods.fml.common.registry.LanguageRegistry;
import green.mods.lapfuel.lib.BlockIDs;
import green.mods.lapfuel.lib.Strings;
import net.minecraft.block.Block;
import net.minecraft.block.material.Material;
import net.minecraftforge.common.MinecraftForge;
import green.mods.lapfuel.core.Main;

public class LapFuelBlocks {




public static Block LapronBlock;

public static void init(){

	LapronBlock = new LapronBlock(BlockIDs.LAPRON_BLOCK);


	LanguageRegistry.addName(LapronBlock, "Lapron Block");
	GameRegistry.registerBlock(LapronBlock, Strings.LAPRON_BLOCK_NAME);
	MinecraftForge.setBlockHarvestLevel(LapronBlock, "pickaxe", 3);

}


}

I'm not completely positive, but I believe your problem is you haven't added a variable for the material, it should be something like this:

Public LapronBlock(int id, Material mat)

instead of what you currently have it. Try that and if it doesn't work post the error on here.

 

Thank you for the help sadly it did not work but i did get the error from eclipse
