Where is the gamemodes tab in singleplayer?

So Im coding a gamemode, but I cant find the gamemode tab :saddowns:
Where is it?

You mean when you start a server? In the start server window, on the right hand side, there are 3 icons. One like a globe, for a map, another like a wrench, for settings, cvars, etc, and then one other. I assume that’s what you’re talking about.

What, no. There isn’t a start server thing in my garry’s mod.

It’s now the same as Single Player, just a different button. Don’t double click the map.

it’s on the right. the tool picture.
