I get this when I run my solar panel add-on.

 

java.lang.RuntimeException: class net.minecraft.src.GreenEnergy.Solar.TileEntitySolar is missing a mapping! This is a bug!

I have no idea what's wrong.

super(par1, Material.iron);

        this.setBlockBounds(0, 0, 0, 1.0F, 0.3F, 1.0F);

}

 

@Override

public TileEntity getBlockEntity(int meta)

    {

return new TileEntitySolar();

    }

@Override

return null;

}

    {

   

    TileEntity blockEntity = par1IBlockAccess.getBlockTileEntity(x, y, z);

    int meta = par1IBlockAccess.getBlockMetadata(x, y, z);

    if(meta == 0)

    {

    {

        return false;

    }

  public void addCreativeItems(ArrayList items){

  items.add(new ItemStack(this,1));

  }

}

Please explain what the missing mapping is so I can release this mod. Thanks!

Also, how do I extract my classes and stuff from the jar to distribute?

Likely you did not register your TileEntity mapping in your load function in the mod_Whatever file.

He is right. Use ModLoader.registerTileEntity...

 

Search google for how to distribute your mod. Thre are so many tutorials out there on this.

Please remove this topic! I solved the problem!

Leave it so other people who encounter the same problem can see.
