[Solved] Any example for creating a battle log on the screen?

[wanyc]

I was thinking about create a battle log screen/window on the right side of the game, recording things such as "xx attack you and you dodged", "you attack xx and xx lost 4 health points" something like that. When the information is too much, a scrollbar would appear.
I think it is quite similar to dialogue history, but it is on the same screen of the game. My first thought was using vbox, I check the instruction and found that you need to add text beforehand, not automatically with games. besides there is no mention of scrollbar. So I am wondering is there any example I can follow? Or this kind of log system is just impossible for renpy. Thanks.

It really depends on your battle system, but for what you're trying to achieve you can use screens for it https://www.renpy.org/doc/html/screens.html such as using a blank frame for the box then you populate it later with data. As for the scroll part, you can use the viewport to make it https://www.renpy.org/doc/html/screens.html#viewport and in the renpy cookbook you should be able to find tutorials on scroll bars. As I said earlier, it will really depend on your battle system.

Thanks a lot, I am gonna try this. Do you happen to know the code to populate data? I check the page of screens several times and I couldn't find it.

You can try this (not tested):

Code: Select all

default histo = []

init python:
    def log(txt):
        histo.append(txt)
        renpy.hide_screen("myhistory")
        renpy.show_screen("myhistory")
        
screen myhistory():
    viewport:
        mousewheel True
        draggable True
        scrollbars "vertical"
        yinitial 1.0
        vbox:
            null height 10
            for i in histo:
                text i
                
label start:
    $ log("Troll insults you, -5HP.")                
    pause
    $ log("You punch Troll, -2HP.")
    pause
    $ log("Troll punches you, -500000HP.")
    pause
    $ log("GAME OVER")
    pause
    return

    $ log("Troll insults you, -5HP.")                
    pause
    $ log("You punch Troll, -2HP.")
    pause
    $ log("Troll punches you, -500000HP.")
    pause
    $ log("GAME OVER")
    pause
    return

Thanks a lot! This is exactly what I want, although "pause" freezes the screen and would not recover no matter what I click so I cannot test the scroll part. Anyway, I think I don't need pause in my game so that is just fine. Thanks again
