Solved Call to a member function setCount() on integer? Need Help. (Please lock thread now)

Hello,

Im having problems when im throwing a snowball. It says the error (Its in the title). How would I be able to fix that thx!
Here is my code:

PHP:

 $f = 1.5;
                        $snowball = Entity::createEntity("Item", $player->getLevel()->getChunk($player->getFloorX() >> 4, $player->getFloorZ() >> 4), $nbt, $player);
                        $snowball->setMotion($snowball->getMotion()->multiply($f));
                        if($player->isSurvival()){
                            $item->setCount($item->getCount() - 1); // Here's where the error happens.
                            $player->getInventory()->setItemInHand($item->getCount() > 0 ? $item : Item::get(Item::AIR));
                        }
                        $player->getLevel()->addSound(new LaunchSound($player), $player->getViewers());
                        $snowball->spawnToAll();

The var '$item' is a integer. I believe it should be a Item or Entity instance?

Oh ok let me try

How would you write it.

Idk I just work here.

Can you post the full code? Especially the part where you defined $item

Can you put all the code ?

PHP:

                        $f = 1.5;
                        $item = getItem()->getId(); // Here is where I defined $item
                        $snowball = Entity::createEntity("Item", $player->getLevel()->getChunk($player->getFloorX() >> 4, $player->getFloorZ() >> 4), $nbt, $player);
                        $snowball->setMotion($snowball->getMotion()->multiply($f));
                        if($player->isSurvival()){
                            $item->setCount($item->getCount() - 1); // Heres the error
                            $player->getInventory()->setItemInHand($item->getCount() > 0 ? $item : Item::get(Item::AIR));
                        }
                        $player->getLevel()->addSound(new LaunchSound($player), $player->getViewers());
                        $snowball->spawnToAll();
        }
    }
}

Your $item is defined with a null value because you defined it wrong.


This is in an event ?

Oh yah sorry but thats not the problem.

PHP:

 $f = 1.5;
                        $item = $ev->getItem()->getId(); // Fixed @Asparanc and this is where id defined it
                        $snowball = Entity::createEntity("Item", $player->getLevel()->getChunk($player->getFloorX() >> 4, $player->getFloorZ() >> 4), $nbt, $player);
                        $snowball->setMotion($snowball->getMotion()->multiply($f));
                        if($player->isSurvival()){
                            $item->setCount($item->getCount() - 1); // Heres the error 
                            $player->getInventory()->setItemInHand($item->getCount() > 0 ? $item : Item::get(Item::AIR));
                        }
                        $player->getLevel()->addSound(new LaunchSound($player), $player->getViewers());
                        $snowball->spawnToAll();
        }
    }
}

Change $item to $item = $ev->getItem();
You cant get the count of an item ID.

Ok let me try that.

Use :

PHP:

$item = $ev->getItem();

What you wrote have a value of the ID of an item (like 12 87 etc...) you can't use function on an number, you need to return an instance of the item.

I already said that.. or did we reply at the same time? Lol

Ohhh wait ok i was gonna post a error until you told me that let me try it and thx

lel. He was saying to do instanceof. ok brb let me test.

Yes xD

getItem() return the instance of the item

Um not exactly. He said u need to return an instance of an item, not an intege. getId() returns an integer.

soo you do this?

PHP:

 $f = 1.5;
                        $item = getItem() instanceof Snowball; //?? lol
                        $snowball = Entity::createEntity("Item", $player->getLevel()->getChunk($player->getFloorX() >> 4, $player->getFloorZ() >> 4), $nbt, $player);
                        $snowball->setMotion($snowball->getMotion()->multiply($f));
                        if($player->isSurvival()){
                            $item->setCount($item->getCount() - 1);
                            $player->getInventory()->setItemInHand($item->getCount() > 0 ? $item : Item::get(Item::AIR));
                        }
                        $player->getLevel()->addSound(new LaunchSound($player), $player->getViewers());
                        $snowball->spawnToAll();
        }
    }
}
