Usage of invoke_in_new_context function

[kallistThe]

I develope a kind of text quest using Ren'Py engine.

There are a lot of mini games. One of them offers player to react properly to some events.



There is a timer that periodically triggers some event. The player sees event text in Ren'Py basic spaech placement and needs to click one of theree imgbuttons.
Timer triggers a fucntion with the code:

Code: Select all

def operate_cave_action(action):
        ......
        renpy.hide_screen("ch6_countdown")
        renpy.invoke_in_new_context(renpy.say, "", message)
        renpy.call("ch6_idle")
        return

Label ch6_idle has the following code:

Code: Select all

label ch6_idle:
		........
                $ ch6_timer_range = max(ch6_timer_range - ch6_timer_reduce, ch6_timer_min)
                $ ch6_time = ch6_timer_range
                $ ch6_event = roll_cave_enent()
                show screen ch6_countdown()

                $ ch6_event_text = ch6_cave_events[ch6_event]

                label ch6_action_blocker:
                    "[ch6_event_text]"

So all that works properly... but I have a little problem
After finishing that mini-game the basic Ren'Py field that displays text continue to display event text when all other renpy.say functions are fulfiled.
That make me think that I don't finish some context or smth like that.

Is that OK or I need to change something in my code?
Thank you!

If you call something, you have to return from it. Are you returning from ch6_idle?

No... Where should I use return? Inside renpy code after label ch6_idle?

Yes, every label should end with either a return statement or a jump. Otherwise the Renpy game pointer will advance after that label (probably into another label or if you're lucky to the end of the file and therefore return automatically). Labels are are not closed automatically by the code's format like a Python function.

By the way, in your code you have "ch6_action_blocker" indented into the other label. But only sublabels (names starting with a dot) are considered part of the outer label.

Code: Select all

label mylabel:
    ...
    label .sublabel:
        ...
    return

label mylabel2:
    ...
    return

Oh, I see, thank you! Now try to understand where I should paste return statement.

By the way, after I use invoke_in_new_context function function, Ren'Py hides all screens. How can I show them in that new context?

I wouldn't use any new context at all, maybe just return to the current statement after the call. Try if it makes sense in your project. So basically, you call a label, that shows the message, that then calls your idle label, after both returning, the function will go back to where it started, showing the last message again.

Code: Select all

default message = ""

init python:
    def operate_cave_action(action):
        global message
        ......
        renpy.hide_screen("ch6_countdown")
        # nope ... renpy.invoke_in_new_context(renpy.say, "", message)
        # nope ... renpy.call("ch6_idle")
        renpy.call("ch6_interrupt", from_current=True)
        return
        
label ch6_interrupt:
    # assuming "message" is a global variable
    "[message]"
    call ch6_idle
    return
    
label ch6_idle:
    ...
    return
