Hello,

I'm trying to animate a 2D array, but it's not Working :(
Here is my code :

import numpy as np
import matplotlib.pyplot as plt
from matplotlib import cm, animation

INDEXTABLE = 20
fig, ax = plt.subplots()
i = 0


def updated(*args):
    global i
    if i < 99:
        i += 1
    else:
        i = 0
    img.set_data(alive(mat))
    return img


def alive(mat):
    
    #Some working stuff wo take a mat as parameter and return modified mat
    return mat


mat = np.zeros((INDEXTABLE, INDEXTABLE))
#define a glider
mat[10, 10] = 1
mat[11, 11] = 1
mat[12, 9] = 1
mat[12, 10] = 1
mat[12, 11] = 1
img = ax.imshow(mat, interpolation='None', cmap='viridis', aspect='equal')

ani = animation.FuncAnimation(fig, updated, interval=50)

plt.show()

I tried many things to make it working : change set data to set array, add parameters att updated function ... but i cant find the right Solution
Thanks for help guys !

Edit : i forgot to tell you something strange : when i put a breakpoint on my updated function, the function is never reached.

No solution found (Up !)
