Issues with instanceof and getId()

You cant check if a tile in getTiles is a sign by using these 2 things up here, so how can I get it working?

Try:

PHP:

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

Be careful, "Sign" class could be either type of Block, Item or Tile... Check your namespaces twice

Oh I already got the problem solved by getting the sign as block and then getting its id, but I still wonder why it has entity like IDs and wasnt also recogized as an instanceof the Sign class, even as I dumped the type using get_class() hmm

The problem was that instanceof Sign doesnt work for me.

What are you willing to work with? Block or Tile?

The tile, to modify the sign text.

Make sure you have `use pocketmine\tile\Sign;`?

How to debug:

1. Do var_dump($sign instanceof Sign) to make sure that it is this line that has a problem.
2. Do var_dump(get_class($sign)) to make sure you indeed have signs in your world.
3. Do var_dump(Sign::class) to check if you got the imports right.

I debugged everything hmm

Are the chunks loaded at all? What is the output of the var_dump()s?

The sign instance, but when I do instanceof it returns false

So, have you tried `var_dump(get_class($sign) === Sign::class)`? I still believe that you have a typo in your use statement for pocketmine\tile\Sign.

No, I dumped with get_class, I even copied the class name from the docs, to be sure
