Here is a short example of how to make a simple dice rolling animation.
A fairly short program is needed to make this possible.
from microbit import * import random faces = [Image('00000:00000:00900:00000:00000:'), Image('00009:00000:00000:00000:90000:'), Image('00009:00000:00900:00000:90000:'), Image('90009:00000:00000:00000:90009:'), Image('90009:00000:00900:00000:90009:'), Image('90009:00000:90009:00000:90009:')] def RandomImages(n, delay): for i in range(0,n): display.show(random.choice(faces)) sleep(delay) display.clear() sleep(delay) while True: if button_a.was_pressed(): RandomImages(20, 75) rolled = random.choice(faces) display.show(rolled)
The faces list is a list of images of the possible die rolls. Dots are used in the classic way.
The RandomImages function is not strictly necessary. Before choosing the final roll, a sequence of randomly selected images is shown blinking on the matrix.
This code never works with the numbers. If you needed to use the die roll in part of a game, generate a random integer from 0 to one less than the number of images. When you need to work with the image (to display it), you write image_list[random_integer], where these words are replaced by your own variables which store those things.
- Replace the images here with your own selection. Perhaps use that as part of a game.
- Instead of choosing randomly from the list, you could use it as a series of images in sequence, as an animation. You can make lists of lists. If you make several lists of images that each make up a short sequence of movements, you can make a random animation. Get the right mix of sequences and you can create something quite effective.
