I don’t know why but my "def" that checks 3 rules of "Game of live" doesn’t work correctly. I have 2 lists that contains 0 and some 1 to check the program. 3 points that should give this image but instead it gives this
def upd(mass,screen,WHITE,mass1):
BLACK = (0,0,0)
for i in range(len(mass)-1):
for j in range(len(mass[i])-1):
if mass[i][j] == 0:
if near(mass,i,j) == True:
mass1[i][j]=1
print("case1")
if mass[i][j] == 1:
if (near(mass,i,j)==False):
mass1[i][j]=0
print("case 2")
if (near(mass,i,j)==False):
mass1[i][j]=0
print("case 3")
for i in range(len(mass1)-1):
for j in range(len(mass1[i])-1):
if mass1[i][j] == 1:
p.draw.rect(screen, (WHITE), Rect((j*10,i*10), (10,10)))
else:
p.draw.rect(screen, (BLACK), Rect((j*10,i*10), (10,10)))
mass=mass1
def near(mass,i,j):
counter = 0
if mass[i][j+1]==1:
counter+=1
if mass[i][j-1]==1:
counter+=1
if mass[i+1][j]==1:
counter+=1
if mass[i-1][j]==1:
counter+=1
if mass[i+1][j+1]==1:
counter+=1
if mass[i-1][j+1]==1:
counter+=1
if mass[i+1][j-1]==1:
counter+=1
if mass[i-1][j-1] == 1:
counter+=1
if counter<2 or counter == 0:
return False
if counter > 3:
return False
if counter == 3:
return True
log that repeats every circle
I am not good in python so I think this code is quite scarry:)
I’ll be very grateful for any advice
>Solution :
mass = mass1 does not copy the contents of the grid, it just puts a reference to mass1 in mass (actually only in the local variable mass in scope of upd). You must deep copy the grid:
for i in range(len(mass1)):
for j in range(len(mass1[i])):
mass[i][j] == mass1[i][j]
