I made a config file and added my blocks, however I crash when I start the game.

Base Mod File Code:

public static int berryBushStartId;
public static final Block BerryBushes = (new ThorMod_Berries(berryBushStartId)).setHardness(0.0F).setStepSound(Block.soundGrassFootstep).setBlockName("BerryBushes").setCreativeTab(CreativeTabs.tabDecorations);

public static int oresStartId;
public static final Block Ores = new ThorMod_Ores(oresStartId, Material.rock).setBlockName("ThorOres").setCreativeTab(CreativeTabs.tabBlock).setHardness(4F);

@PreInit
public void preInit(FMLPreInitializationEvent event)
{
	proxy.registerRenderInformation();
	new ThorMod_Configuration(event);
}

 

ThorMod_Configuration:

package thormod;

import net.minecraft.src.*;
import net.minecraftforge.common.Configuration;
import cpw.mods.fml.common.event.FMLPreInitializationEvent;

public class ThorMod_Configuration
{

public ThorMod_Configuration(FMLPreInitializationEvent event)
{
	Configuration config = new Configuration(event.getSuggestedConfigurationFile());

	config.load();


	this.blocks(config);


	config.save();
}

public void blocks(Configuration config)
{

	ThorMod.berryBushStartId = config.getBlock("Berry Bushes' Start ID", 158).getInt();

	ThorMod.oresStartId = config.getBlock("Nether & End Ores Start ID", 2723).getInt();

}

}

 

Does anyone see the problem?

It looks like your config file isn't being loaded you could try looking at this tutorial as it shows how to make a simple/advanced config file

 

http://www.minecraftforge.net/wiki/How_to_make_an_advanced_configuration_file

thats the tut I used

So, derp,

 

First, blocks should return config or edit a global one. Do this or the config file won't save the changes.

Second, why you make a new object rather than run static functions, ill never know. It will make minecraft go a little faster too.

Three, the whole config thing should be in a try catch thing so you don't crash minecraft. You might wanna, I dunno.

Four, have the blocks names be global but initialize them after you get all the data for them (block/item id). You would also have global variables of the block id's or put them in a separate objects or array for easy organization.

 

I think that's it, I hope I helped.
