[1.8] Open custom Gui

[MacDue]

Hi, I just wanted to make a little custom gui to replace the normal furnace one (for my custom furnace).

 

However I cannot find anyway to get it to open.

 

    public boolean onBlockActivated(World worldIn, BlockPos pos, IBlockState state, EntityPlayer playerIn, EnumFacing side, float hitX, float hitY, float hitZ)
    {
        if (worldIn.isRemote)
        {
            return true;
        }
        else
        {
            TileEntity tileentity = worldIn.getTileEntity(pos);

            if (tileentity instanceof TileEntityEpicarnoFurnace)
            {
            
                
         FMLNetworkHandler.openGui(playerIn, mystical_epicarno_mod.instance,0, worldIn,pos.getX(), pos.getY(),  pos.getZ());

            }

            return true;
        }
    }

Ugh nothing seems to get called anywhere, it does not seem to even try to open any GUI.

[jabelar]

Use playerIn.openGui() method not the FMLNetworkHandler.

[MacDue]

That has no effect

 

 playerIn.openGui(mystical_epicarno_mod.instance, 0, worldIn,pos.getX(), pos.getY(),  pos.getZ());

 

Still nothing opens

[MacDue]

Is there anyway to get some form of error msg, right now it does not seem to make any attempt at doing anything.

[MacDue]

I'm not anymore, but I still can't get the custom GUI to show up.

[MacDue]

Okay, the container and GUI right now are just ripped from the Vanilla classes as I wanted to get the GUI opening before I edited them.
