.push() is not a function ._. [solved]

[Nilom]

Hello!

I used .push() for a card drawing skill system before.

But when I try to do something similar and store movement commands (numbers) inside an array then I get ".push()" is not a function.

What did I do wrong? I just do not see it:

if ($gameMap.regionId($gameMap.event($turn_number).x-1,$gameMap.event($turn_number).y) == 8) {
    $look_dir[$turn_number] = 17;
    $backfinding[$turn_number].push(18);
    console.log("look_dir: left");
}
if ($gameMap.regionId($gameMap.event($turn_number).x+1,$gameMap.event($turn_number).y) == 10) {
    $look_dir[$turn_number] = 18;
    $backfinding[$turn_number].push(17);
    console.log("look_dir: right");
}
if ($gameMap.regionId($gameMap.event($turn_number).x,$gameMap.event($turn_number).y-1) == 1) {
    $look_dir[$turn_number] = 19;
    $backfinding[$turn_number].push(16);
    console.log("look_dir: up");
}
if ($gameMap.regionId($gameMap.event($turn_number).x,$gameMap.event($turn_number).y+1) == 17) {
    $look_dir[$turn_number] = 16;
    $backfinding[$turn_number].push(19);
    console.log("look_dir: down");
}

Note that it is intended that I mirror the direction numbers. Because "backfinding" is all the commands from "pathfinding" backwards.

Thanks in advance!





Edit:
Nevermind, I found the issue. I was defining $backfinding wrong.
What I did:

$backfinding = [0, 0, 0, 0, 0]

What I should have done:

for (var i = 4; i > 0; i--) {
$backfinding[i] = []
}

I don't know about the plugins you are using or the code you wrote, but if you console.log $backfinding[$turn_number] what does it show? .push() works on arrays, so if it's trying to use .push() on an integer or something it will display an error.
