Attempting to make a code lock

[burnt_offering]

Basically, I've been trying to code a gameplay element, in which at one point there's a door with a number lock on it.
Now, the code was fairly okay:

Code: Select all

screen GenCodeInput:
    tag puzzle
    use navigation
    imagemap:
        ground "gencode.png"
        idle "gencode.png"
        hover "gencodehover.png"
        
        hbox:
            for i in (0,9):
                textbutton str(i):
                    if code==0:
                        code=i
                    elif code<10:
                        code= 10*code + i
                    elif code>9999:
                        codestring=str(code)
                        for ch in codestring:
                            codestring2 = str(codestring[-4:])
                            code = int(codestring2)
                            code = 10*code + i
                    ground "gencode(%code).png"
            textbutton clear:
                code=0
        

The problem is that this requires 10000 images, one for each possible number, which simply isn't feasible. Is there some way I can do this more efficiently?

How about the way real code locks do it? 10 images for the numbers 0-9, 4 of them to display a 4-digit number?

I guess if I used a different variable for each position I could do that.
