Hi,
I'm relatively new to C#. At the moment I am creating a menu for a gaming project that I am developing.
The menu that I am having a problem with is the Gameplay Screen. I am trying to put my own code in to display a model from the tutorial on menus from this site.
I am getting this error:
GameStateManagement.GameplayScreen.LoadGraphicsContent(bool)': no suitable method found to override.
Here is the code that is giving me that error:
namespace GameStateManagement
{
/// <summary>
/// This screen implements the actual game logic. It is just a
/// placeholder to get the idea across: you'll probably want to
/// put some more interesting gameplay in here!
/// </summary>

{

Please help. This error has been driving me mad!!
