[ashen nova]

What do you mean you call with an egg? You spawn an entity using spawn egg?

Sorry I forgot. I'll try to make if what's on my mind will gonna work.

@wary pawn Here it is.

// The event we need to use to detect if player use a spawn egg to summon entity
// BeforeEvents is use to sync it with Promise function
world.beforeEvents.itemUseOn.subscribe((data) => {
    const {itemStack, source} = data;

    // Check if the item use is any spawn egg
    if(!itemStack.typeId.endsWith('_spawn_egg')) return;
    system.run(async() => {
        // Call the Promise function that detect which entity will spawn
        const entity = await getEntitySpawn();
        // Setting nameTag of an entity to player's name
        entity.nameTag = source.name;
    });
});

// A Promise function to detect what entity will spawn
function getEntitySpawn() {
    return new Promise((resolve) => {
        world.afterEvents.entitySpawn.subscribe(data => {
            const {entity, cause} = data;

            if(cause === 'Spawned') {
                // Resolve the entity so we can retrieve this when calling the function
                resolve(entity);
            }
        });
    });
}

Don't forget to unsubscribe from the afterEvent in the getEntitySpawn function

[ashen nova]

I also thought that, however idk how do I properly unsubscribed. I have never used this. Could you please teach me how?

[obsidian badge]

Yeah, so the subscribe method takes a function as an argument to start the subscription and the unsubscribe actually takes the same argument to remove the subscription. Luckily subscribe also returns the subscription function, so you can store that in a variable and then pass it to unsubscribe when needed.

function getNextSpawnedEntity() {
  return new Promise((resolve) => {
    const spawnSubscription = world.afterEvents.entitySpawn.subscribe(
      (event) => {
        if (event.cause === EntityInitializationCause.Spawned) {
          world.afterEvents.entitySpawn.unsubscribe(spawnSubscription);
          resolve(event.entity);
        }
      },
    );
  });
}

[ashen nova]

I thought the subscribe returns void?

Well, thank you so much, I'll try this.

[ashen nova]

It works, it unsubscribe properly. I'm just confused because it says it returns void, but it's the arg that return void, right?

[obsidian badge]

Yeah, the subscribe method takes the callback argument, that has type (arg: EntitySpawnAfterEvent) => void, which means "a function that accepts one argument that has the type EntitySpawnAfterEvent that is not guaranteed to return a value (void)" and returns (arg: EntitySpawnAfterEvent) => void

[ashen nova]

Thanks for explaining, I understand now.

[broken patio]

Guys, can I ask you a quick question?

[ashen nova]

You already did.

[broken patio]

....

[ashen nova]

Just kidding, go ahead.

[broken patio]

It's like that and I wanted to know how I could execute a function after pressing a button on the interface

[ashen nova]

I thought you will ask something relevant to our discussions. Why don't you create a post for that?

[ashen nova]

Anyway here's a tutorial.

Okay, I'll create it
