Duplicating identical images for a sewing minigame [SOLVED]

[strikerofchords]

Hello! I'm a relative newbie at programming and Ren'Py, so my apologies if this is a silly question and/or my code is totally janky. I am currently trying to program a very simplistic sewing minigame where the player follows a sequence of commands to create a bunch of stitches. I'm able to get the sequence and key-presses to go just fine, but my issue comes with displaying a trail of completed stitches behind where the needle and thread are currently. The most I've been able to get is a singular stitch to appear in the previous position, but it simply moves as soon as the show command is re-triggered. Here's the code (apologies if I attach too much or too little, it's my first time making a post like this on here):

Code: Select all

default step = 0		# Tracks which step the player is currently at
default stitchxPos = 1200		# xPosition of the needle
default stitchList1 = ["U","R","L","U","R","L","U","R","L"] # The sequence of stitches

label loopback:
        if step < len(stitchList):
            $ currentStep = stitchList[step]
            $ print(currentStep)
            if currentStep=="U":
                show Needle1 Up at needleThread
                show Point Up at truecenter
                call screen sewingMinigame("up")
            elif currentStep=="R":
                show Needle1 Right at needleThread
                show Point Right at truecenter
                call screen sewingMinigame("right")
            elif currentStep=="L":
                show Needle1 Left at needleThread
                show Point Left at truecenter
                call screen sewingMinigame("left")
            screen sewingMinigame(direction):
                key ("input_"+direction) action Call("miniContinue")
            label miniContinue:
                if currentStep=="U":
                    show stitchDone at needleThread # This is my working solution to my issue
                    $ stitchxPos += -80
                $ step+=1
                jump loopback
        else:
            hide Point
            hide Needle
            return

I know that the show function isn't ideal for solving this problem, but when I used the add function from the screens it failed to loop back, and I couldn't wrap my head around SpriteManagers. I haven't been able to find anyone else in the same scenario as me, so if anyone could help me figure out how to create a trail of duplicate images, I would appreciate it.

With any approach (`show` or `add` or even using cdd) you have to use a cycle to draw all stitches from number 0 to the last one. Something like (show screen ...)

Code: Select all

for i in range(0, step):
    add <the image of the stitch number i>

Then adding another stitch you'll increase `step` and the screen would show the stitches again, with one more.

PS. Another reference about

a sequence of commands to create a bunch of stitches.

- an example of doing that with CDD:

You might prefer usual images instead of CDDs, but using the "for" loop etc. can be the same.
