A new screen question

[Karasu_Noir]

Scrolled through the renpy cookboks and tutorials, and wondering how to create an in-game ui button which when it is clicked,it brings up a new label (I plan to make it the label for viewing explanations, so that the players can look at it anytime when they forget something. My game has many japanese terms.) Can you help?

[Chansel]

Try editing this to your liking (it's what I'm using for a 'stats' button):

Code: Select all

ui.hbox(xpos=369, ypos=561, xanchor='left', yanchor='top')
ui.imagebutton("idle.png", "hover.png", clicked=ccinc("explanations"), xminimum=62, yminimum=36)
ui.close()

"explanations" would be the name of the label in this case
I'm not 100% sure this is the best way to do it, but it works =D

I'm sorry, but an exception occured while executing your Ren'Py
script.

NameError: name 'ccinc' is not defined

While running game code:
 - script at line 876 of D:\renpy-6.10.2\Hikaru_Wish/game/script.rpy
 - python at line 876 of D:\renpy-6.10.2\Hikaru_Wish/game/script.rpy.

Oh, oops Sorry 'bout that.
I'm using the on screen buttons cookbook thing which defines ccinc ^^" http://www.renpy.org/wiki/renpy/doc/coo ... _Game_Menu
You actually might want to take a look at that
Anyway, replace it with this:

Code: Select all

renpy.curried_call_in_new_context("explanations")

and it should work.

[Karasu_Noir]

So, in the script at the point when I want to button to appear...

Code: Select all

 
    himiko "You can check the dictionary every time."
    $ ui.hbox(xpos=369, ypos=561, xanchor='left', yanchor='top')
    $ ui.imagebutton("idle.png", "hover.png", clicked = renpy.curried_call_in_new_context("explanations"), xminimum=62, yminimum=36)
    $ ui.close()
    himiko "Good." ## ui.umagebutton dissapears? Why?
   ##some more scripts
   himiko "Now I want to borrow the dictionary"
   ## The ui.image button dissapears here

But it dissapeared at the next dialouge, when himiko talks again. How do I make it appear until some point in the game?

[Chansel]

Aha. Well, that's because it's supposed to go in an init python block ^^" Which goes before your start label.
And if you want it to appear at a certain time, use a variable for that.

Code: Select all

init python:
    show_button_game_menu = False
    
    def button_game_menu():

        if show_button_game_menu:
            
            ui.hbox(xpos=281, ypos=575, xanchor='left', yanchor='top')
            ui.imagebutton("idle.png", "hover.png", clicked=renpy.curried_call_in_new_context("explanations"), xminimum=37, yminimum=22)
            ui.close()   
            
    config.overlay_functions.append(button_game_menu)    

label start:

"No button"
$ show_button_game_menu = True
"Yay, a button!"
"Extra text :)"
$ show_button_game_menu = False
"Bye, button :("

So, basically, the game starts of with the button turned off. To turn it on, set show_button_game_menu to True To turn it off again, set it to False.
Sorry for taking so long in helping out.. I'm still new to the whole 'helping people out' thing ^^"
Anyway, this should work =D (tested it in an empty template, just to be sure XD)

[Karasu_Noir]

Code: Select all

 $ show_button_game_menu = False
   
    def button_game_menu():

        if show_button_game_menu:
           
            ui.hbox(xpos=281, ypos=575, xanchor='left', yanchor='top')
            ui.textbutton("Dictionary", clicked=renpy.curried_call_in_new_context("explanations"), xminimum=37, yminimum=22)
            ui.close()   
           
    $ config.overlay_functions.append(button_game_menu)

shows

Code: Select all

[Chansel]

That's because you added two '$'
Just copy past everything from above the start label and it should work.

[Karasu_Noir]

Hmm...

[Chansel]

Alright, I'm lost :S
I copy pasted everything in an empty renpy files and it works fine for me...
Expected statement is usually something with identation or when there's a colon missing or something. Make sure all your identations are correct and check if you didn't accidentaly deleted a colon or something.

I think because I have init: so I put the code right below init:

I put init phyton: and init: in a separate place and it worked.
Thank you.

Another question, so I made a new label, how do I make it return to the scene where I clicked it before?

Code: Select all

label explanation: 
   scene bg dict
   ## Long, long explanation
   ##Want to put a button to return to the previous scene

I think you don't need to do that, because the scene returns when you click at the explanation label after the long explanation is done. Maybe it is you who did something wrong.

[Alex]

When you "call" some label "in new context", you need to "return" to game context.

Code: Select all

label explanation: 
   scene bg dict
   ## Long, long explanation
   
   return 

If you need a button, it could be like

Code: Select all

label explanation: 
   scene bg dict
   ## Long, long explanation
   
   $ ui.textbutton ("Return", clicked=ui.returns("True") #place the button on the screen (add xpos, ypos, xalign etc. to change its position; this button actualy do nothing - its just clickable
   $ ui. interact() # game will wait until button clicked
   # when button clicked, we can go farther
   return

That's nice! *writes code*
