and IGuiHandler code (Used it in common proxy) :

 

package ga.warixmods.mymodmod.proxy;

 

import ga.warixmods.mymodmod.inventory.GuiWand;

import net.minecraft.entity.player.EntityPlayer;

import net.minecraft.world.World;

import net.minecraftforge.fml.common.network.IGuiHandler;

 

public class CommonProxy implements IGuiHandler {

    @Override

    public Object getClientGuiElement ( int ID, EntityPlayer player, World world, int x, int y, int z ) {

    if ( ID == GuiWand.GUI_ID )

            return new GuiWand();

    else

            return null;

    }

 

public void registerRenders()

{

 

}

 

@Override

public Object getServerGuiElement(int ID, EntityPlayer player, World world, int x, int y, int z) {

 

return null;

 

}

}

 

I'm new to modding and this is my first mod ever so its probably something very simple.

Also here is code that calls gui :

public boolean onItemUse(ItemStack stack, EntityPlayer playerIn, World worldIn, BlockPos pos, EnumFacing side, float hitX, float hitY, float hitZ)

{

if(playerIn.isSneaking())

{

 

playerIn.openGui(mymod.instance, GuiWand.GUI_ID, worldIn, 0, 0, 0);

 

}

    return false;

}

 

 

Oh thanks, i followed this tutorial: http://www.minecraftforge.net/wiki/Basic_GUI , and i confused BasicGui with GuiBasic , i changed  public static GuiWand instance; to  public static mymod instance; and now it works fine.
