Ok. So...
I was wandering about making a multiplayer mod, and I thought, 'How would I add in GUI's, like in TF Classic?' So I looked around, but I couldn't find anything on it. When I say GUI, by the way, I don't mean the splash screen or HUD, but the box which lets you select a team in Team Fortress Classic- or what I really want is a GUI that lets you place entities IN-GAME. Like the Engineer class. I really want something like that which I can make, to spawn in entities of my choosing in GoldSrc. Any ideas?
Thanks. Oh, and by the way- this would be a Multiplayer/Singleplayer Half-Life mod I'm talking about, not a TF Classic mod or CS mod.
Thankyou!
