Dynamic Signs help

I made a dynamic sign plugin but it only has 1 sign that can be used. I have only one update sign task but how would I make it work with multiple signs?

PHP:

foreach($level->getTiles() as $tile){
    if($tile instanceof Sign){
        //code here
    }
}

Use arrays.

So save the sign vector in array? Because I use vector to check if the sign is right.

Better to save the title

Try using Level::blockHash()

Why not to store the "Tile Object"

What does this do?

I thought storing the tile is not good? So the check if the tile if the tile I saved is same as the tile I am going to check?

I mean as the key.

I always use "$tile->getId()"

I save my dynamic signs in config file and load them in array:
signs.yml

Code:

1:
 x: 143
 y: 53
 z: 71
 level: Lobby
 type: join

Update them on timer.

Maybe faster searching?

I thought IDs change...

At least not in the same runtime.
We don't know what you want. When you talk about saving into an array, we expect it to be runtime-local.

I mean that when a server stops and starts, it can read cords from the config and keep the task running and updating the sign.
