Custom choice menu statement? [SOLVED]

[mikolajspy]

Hi!
For my new project, I want to use few different choice menus depending on situation.
Sometimes I'd use classic, vertical, one column.
But sometimes, I'd like to use horizontal or double-column vertical.
While changing choice screen is not a problem, I don't know how to use duplicate with custom statement.

I've already read Documentation: https://www.renpy.org/doc/html/cds.html

But I don't really know how to use it.
What I'd like to achieve is something just like:

Code: Select all

hmenu:
	"Option 1":
	....
	"Option 2":
	...

And it would result with horizontal styled menu.
And so on if I type "menu2" etc. it would use different layout.

Can someone point me how do I use custom statements to create choice menu?

Or at least, just how to show different choice menu screen with button jump label actions etc.

The current Ren'py menu: statement parses the statement parts in a sort of ad-hoc manner then mashes them all together to fit in with rollback/save/roll-forward/choice locking/remembering and the rest.
As such, it is a bit of a beast to meaningfully extend unless you get quite familiar with the code surrounding the standard menu: block. Even then, you would likely be writing the new lexer/parser and then rewriting a version of the ui.menu function to fit the menu varieties you want.

I would therefore recommend just passing a flag/toggle in with the first choice caption and using the screen choice( items ): to work out what to display...

Pseudo code - probably might need some parts in $ or python: blocks...

Code: Select all

label a:
    menu:
        "h1:Choice A":
...

screen choice(items):
    style_prefix "choice"

    if items[0].caption[:3] == 'h1:':
        items[0].caption = items[0].caption[3:]
        use choice_horizontal_1( items )

    # etc for different styles

Then just write small screens to display each 'first menu item prefix' differently

Of course, variable! I didn't think about it! Thanks for the idea! I made it even easier.
In the end, I just added

Code: Select all

default menu_style = "v"

and later in choice screen, before vbox

Code: Select all

if menu_style == "v":

and below vbox part

Code: Select all

if menu_style == "h":
#Code for another layout

Now I just change variable right before showing menu and it works smoothly
