Hi! I am relatively new to modding, and I have been stumped for a few days as to of why my gui is not showing up on my block.

 

Here is my github link for the project:, the files pertaining to the gui have 'Inscriber' in their name.

looks like your forgot to register your tile entity  it should be working after that

 

public boolean onBlockActivated(World worldIn, BlockPos pos, IBlockState state, EntityPlayer playerIn, EnumHand hand, ItemStack heldItem, EnumFacing facing, float hitX, float hitY, float hitZ) {
        // Only execute on the server
        if (worldIn.isRemote) {
            return true;
        }
        TileEntity te = worldIn.getTileEntity(pos);
        if (!(te instanceof TileInscriber)) {
            return false;
        }
        playerIn.openGui(MysticRune.instance, 0, worldIn, pos.getX(), pos.getY(), pos.getZ());
        return true;
    }

Direct cause: Your second if statement detects if the tile entity at the current position is TileInscriber; however, since your tile entity is not registered, the if statement will always be true and return true before the openGUI method is called.

Fix: Register your tile entity with GameRegistry#registerTileEntity.
