Error "Division by zero in operator '..'.

Question

var paths = []
const path_dir="res://Paths"

func _ready():
    loadPaths()
    pass

func random_path():
    return paths[randi()% paths.size()]
    pass

func loadPaths():
    var dir = Directory.new()
    dir.change_dir(path_dir)
    dir.list_dir_begin()
    var files =dir.get_next()


    while files!="":
        var path = load(path_dir+ files)
        if path && caminho is Curve2D:  
            paths.append(caminho)
        file =dir.get_next()
    pass

What I'm doing wrong?

Answer 1

If the error is pointing at return paths[randi()% paths.size()], the problem is that you are trying to modulo paths.size() which is zero.

If you're using 3.0.2, there was a problem with the operators reported by that error. I reported it here: https://github.com/godotengine/godot/issues/18468. It's been fixed in the latest master and will be correct in 3.0.3.

Answer 2

I am not familiar with your code but shouldn't it be files rather than file in the second last line i.e files = dir.get_next()
