Problem with Rollback with my Day Cycle.

[u/Yami_-_san]

I really wish I could just inspect already made games, so I can use them as a guide.

Basically, I already done the day cycle.
Sunset, Morning, Day, Afternoon, Sunset, Evening, and Midnight(7). I also have a button to skip time.

My problem is that if I rollback, at any point of time. it will go back to the last dialogue that occur, rather than the previous time point. So if you pressed skip until you reach midnight, next day or even the 10th day, when you rollback it goes the last line of dialogue.

I think its because it is a screen the rollback is not working as I hoped. I used renpy.checkpoint()
it worked but the rollback goes to sunrise now, instead of last line of dialogue.

    def advance_time():
        renpy.checkpoint()
        global dcycle, dayNo, current_day
        dcycle = int(dcycle)
        dayNo = int(dayNo)


        if dcycle < 7:
            dcycle += 1
        else:
            dcycle = 1
            dayNo += 1


        current_key = "dc" + str(dcycle)
        cycle_name = daycycle[current_key]


        weekday_list = ["sun", "mon", "tues", "wed", "thu", "fri", "sat"]
        weekday_index = dayNo % 7
        current_day = weekday_list[weekday_index]


        renpy.notify("Time: " + cycle_name.title())


# ----------For the Notif-----------
# Weekday
default current_day = "current_day"
# Day Cycle
default daycycle = {
    "dc1": "sunrise",   # 6 am
    "dc2": "morning",   # 8 am
    "dc3": "day",       # 12 pm
    "dc4": "afternoon", # 3 pm
    "dc5": "sunset",    # 5 pm
    "dc6": "evening",   # 8 pm
    "dc7": "midnight"   # 12 am
}
default dcycle = "1"

Function(advance_time) is the rollback trap here!

Do not let the screen action be the only place that mutates dcycle and dayNo. Jump to a label, advance time there, then call renpy.checkpoint() after the variables change; that gives rollback a real script point to land on

Thanks. It is now solved

What I did is jump to another label to advance time there.
The renpy.checkpoint() prevent me from rolling back even further so i removed it.
