How to use generic menus

[Ershantik]

I've been trying to figure out how to make custom menus for my project, and while I think I'm getting the hang of it, I can't figure out how to make generic menus accessible in-game.

I know that custom list and option menus need to be backed by a MENUDEF entry, but as far as I know, that's not the case with generic menus. But if they're not defined in MENUDEF, how do you link them to other menus that are?

I've been trying to pick apart Doom Delta's code to figure out how their menus work, but I can't seem to find anything about how the generic menus are actually called onscreen.

Submenu "<label>", "<menu block reference>" [, <param>] [, <centered>]
Opens the listed submenu.

Code: Select all

OptionMenu "TestMenu"
{
Control "Example Label", "whereisini" // this is an example
Submenu "Mouse Options (Submenu method)",  "MouseOptions" // go to the "Mouse Options" menu.
ConsoleCommand "Mouse Options (dedicated command method), "menu_mouse" // Uses the "menu_mouse" command to open the Mouse Options menu.
ConsoleCommand "Mouse Options (openmenu method), "openmenu mouseoptions" // Uses the "openmenu mouseoptions" command to open the Mouse Options menu.

}

I just realized you are talking about the GenericMenu class. You'll need to have a good understanding of ZScript to understand them, and write your own. I can vouch for this guide to learn ZScript, and it's how I* started. Prior programming knowledge is helpful, but not required.

*Not that I'm a ZScript god anyway.

Well I'll be damned, it works. Thanks. That's really the one thing I was hung up on. No matter where I looked, I couldn't find any documentation that explained this about generic menus.

The weird thing is, Doom Delta doesn't seem to use any of the methods you showed me. Their MENUDEF doesn't list any submenus or commands, so I still have no idea how their menus work.

Like I said, it's in the ZScript. Maybe ask the author?

Those methods I showed you are MENUDEF exclusive, so obviously Doom Delta is not using them.

Good luck, and have fun!
