2-D string array with more columns than rows issue

spikey

I am working an game, based on text characters and run into this. Blame me, if its just not the approach how to use an array. I probably better switch to a 1-D array of strings ;-)
ID: LXK738YWK8

a = [ [".", ".", ".", "."], [".", ".", ".", "."], [".", ".", ".", "."] ]
print(len(a), "x", len(a[0]))
print()
a[0][3] = "X" // should not change the amount of rows, just the 3rd element in the first row
print(len(a), "x", len(a[0]))

output:

3x4
4x4

They start off at 0. By setting a[0][3] to ”x”, you’re adding a 4th element. I think it’s fine...

@toxibunny Thanks for reading, but I am not convinced yet. print(a) at the end, returns Unknown type: 4. print() with an array should always return that array, I guess.

I agree with @spikey that this is a bug.

If you print a[0] a[1] and a[2] individually, you do see [".", ".", ".", "X"], [".", ".", ".", "."], [".", ".", ".", "."], but len(a) indicates that there is an a[3], which is not the case and trying to read it, does throw an error.

Oh yeah. Sorry, my mistake.

@spikey said in 2-D string array with more columns than rows issue:

a = [ [".", ".", ".", "."], [".", ".", ".", "."], [".", ".", ".", "."] ]

Do you get the same issue if you initialise a like this instead:

a = [ "....",  "....", "...." ]

spikey

@vinicity interesting, this works for reading form a[0][3] but not writing to it. To write you can only access the whole string then, like a[0]='...X'.
My workaround right now, is just to define the row numbers as fix and not use len(a) to determine it.

Great that you have a workaround. Also, I’m really curious about your new game!

Hello guys

I have a similar problem. I don't understand code very well yet to say whether it is identical to the problem described here or has something to do with it.

This code works very well

myArray = [
[0,0,0,0,0],
[0,0,0,0,0],
[0,0,0,0,0]
]

myArray[1][2] = 1

print[myArray]

Returns:

[ [0,0,0,0,0], [0,0,1,0,0], [0,0,0,0,0] ]

But this code ... :

myArray = [
[0,0,0,0,0],
[0,0,0,0,0],
[0,0,0,0,0]
]

myArray[1][3] = 1

print[myArray]

Returns a ---Error--- : Unknown type: 4

My workaround is to add twice as many rows:

myArray = [
[0,0,0,0,0],
[0,0,0,0,0],
[0,0,0,0,0],
[0,0,0,0,0]
]

myArray[1][3] = 1

print[myArray]

Returns:

[ [0,0,0,0,0], [0,0,0,1,0], [0,0,0,0,0] ]

Is that a bug in Fuze4 ???

@Starshine-Vixen Yes this seems to be a bug. I have tried it with the latest patch (which should be out soon) and it works as expected
