Displaying a random sprite

[CainVoorhees]

I'd like to have my software randomly select a sprite and display it on screen. On top of that, I'd like for it to repeat the process every time I click on it. My initial theory is to have the game randomly pick a number between 1 and 100 (yes, that many sprites) and display the sprite associated with that number.

I got as far as having the game select a random number, but I'm having trouble implementing it without coding elif number = 1, elif number = 2, etc. in each clickable item that will feature this function. With how flexible ren'py is, I'd like to know if there's a much simpler code I could use without having to go into the tedious work that I may have to fall back on.

You can use either

Code: Select all

show expression my_var

where you can set "my_var" to a file name or a displayable, or python equivalent of show statement

Code: Select all

$ renpy.show(my_var)

The choice statement selects randomly an option for display:

And if you want to know which image is displayed, you can try showing, but it might not work with ATL:

I feel like this is what I'm looking for, but I don't understand how I might install it. Although I looked at the tutorial and compared the script, I think I need further explanation as to how one works with ATL in python.

The game is set up on a image map with hotspots. If you click on the "char01" hotspot, a random sprite is supposed to appear in place of the hotspot. I have it set up to when you click on the hotspot, the game selects a random number. Only problem is, the engine doesn't recognize numbers as names.

Code: Select all

label game:
    scene bg starswirl
    $ result = renpy.imagemap("images/whowouldwin-mockup.png", "images/cdef.jpg", [
        #character
        (120, 127, 360, 477, "char01"),
        (600, 127, 840, 477, "char02"),
        ])
    if result == "char01":
        $ char01_roll = renpy.random.randint(1, 8)
        show expression char01_roll at left with dissolve
        jump game
    elif result == "char02":
        $ char02_roll = renpy.random.randint(1, 8)
        show expression char02_roll at right with dissolve
        jump game

I defined the sprites as:

Code: Select all

image c1 = "images/c001.jpg"
image c2 = "images/c002.jpg"
image c3 = "images/c003.jpg"
image c4 = "images/c004,jpg"
image c5 = "images/c005.jpg"
image c6 = "images/c006.jpg"
image c7 = "images/c007.jpg"
image c8 = "images/c008.jpg"
image c9 = "images/c009.jpg"
image c10 = "images/c010.jpg"

Previously, the sprites did not have the "c" prefix. I'm looking at installing 100 sprites...

I also eventually want to set it up so that the program can record which sprites were selected and be able to display those later, but it's one of those "if I have the time" goals.

One can use the choice statement in the init block:

Code: Select all

init:
    $ num = 2
    image somePicture 0 = "c1.png"
    image somePicture 1 = "c2.png"
    image somePicture anotherName:
        "somePicture 1"
    image somePicture rand:
        choice:
            "somePicture 0"
        choice:
            "somePicture anotherName"
init python:
    def showRandom():
        randomNumber = renpy.random.randint(0, num-1)
        renpy.show("somePicture " + str(randomNumber))
        return
label start:
    show somePicture rand
    "..."
    hide somePicture
    $ showRandom()
    "..."
    hide somePicture

Only problem is, the engine doesn't recognize numbers as names.

In the code above I changed integer into string and used the function mentioned by Alex. Perhaps you could use in your code:

Code: Select all

        $ char01_roll = "c" + str(renpy.random.randint(1, 8))
        show expression char01_roll at left with dissolve
