"Failed to call function 'hasTag' at <anonymous>"

[dusky magnet]

To explain the error in full detail, I have 2 scripts.

1. Detects an entity being hurt which checks for the damageSource tag using 'hasTag' for player attacks and checks for the damageSource family using 'hasTypeFamily'

world.afterEvents.entityHurt.subscribe(({ hurtEntity, damageSource: { damagingEntity, damagingProjectile, cause } }) => {

  const playerFamily = damagingEntity?.getComponent('minecraft:type_family');
  const projectileFamily = damagingProjectile?.getComponent('minecraft:type_family');

  if(damagingEntity?.hasTag('player_zero') && playerFamily.hasTypeFamily("player") & cause === "entityAttack" && hurtEntity.typeId == 'test:dummy'){
        hurtEntity.runCommand("say I am hit by an ATTACK!");
        
    }

  if(projectileFamily?.hasTypeFamily('custom_projectile') && cause === "projectile" && hurtEntity.typeId == 'test:dummy'){
        hurtEntity.runCommand("say I am hit by a PROJECTILE!");
    }

});

2. A script that fires a projectile using 'itemUse'

world.afterEvents.itemUse.subscribe((event) => {
  const {itemStack,source} = event
  const {x,y,z} = source.getHeadLocation();
  const headLoc = {x:x, y:y+0.3, z:z}
  const viewDir = source.getViewDirection()

if(itemStack.typeId === 'test:custom_pistol'){
        const bullet = source.dimension.spawnEntity("test:bullet", headLoc);
        const projectile = bullet.getComponent("projectile");

        projectile.owner = source;
        projectile.shoot({x: viewDir.x*5, y: viewDir.y*5, z: viewDir.z*5})
      }
});

When I attack the entity while having the correct tag, I trigger the first command.

if(damagingEntity?.hasTag('player_zero') && playerFamily.hasTypeFamily("player") & cause === "entityAttack" && hurtEntity.typeId == 'test:dummy'){
        hurtEntity.runCommand("say I am hit by an ATTACK!");
        
    }

When I throw a projectile at the entity that has the correct familyType, I trigger the other command.

if(projectileFamily?.hasTypeFamily('custom_projectile') && cause === "projectile" && hurtEntity.typeId == 'test:dummy'){
        hurtEntity.runCommand("say I am hit by a PROJECTILE!");
    }

BUT, when I throw an exploding projectile or trigger any explosion that damages the entity. It triggers the error.

When I "fire" a projectile using the custom pistol item (using script 2), even with the projectile having the correct family type. It still triggers the error. Does it have anything to do with myself being the owner?

Sorry, I'm a bit confused about what the actual error is like, pls send the error.

"Failed to call function 'hasTag' at <anonymous>"

damagingEntity is the projectile...

[dusky magnet]

Hmm..

It works well until I actually use the custom gun.

I need to test for entity attack and a projectile hit.

If I use the custom gun, it registers as an attack instead of a projectile hit I believe.

[dusky magnet]

So I cannot differentiate between a normal attack and a projectile?

[chrome mantle]

display their typeId

Gotta watch which is which

[dusky magnet]

Very well.

[chrome mantle]

That kind of error usually throw when the entity isn't in the world anymore

[dusky magnet]

The bullet does expire on hit.

Perhaps that could cause it?

[chrome mantle]

Hurt event prob triggered 2 times
projectile and explosion
Explosion as the cause and the projectile being the damagingEntity

Tricky eh

[dusky magnet]

Truly.

[chrome mantle]

Well, did u see it's typeId?

console.warn(damagingEntity?.typeId) somewhere there

[dusky magnet]

Changing the values at the moment.

[dusky magnet]

If I have the tag and it's a melee attack. It tells me it's from the player.

[dusky magnet]

When I use the projectile that has the correct family, it tells me the ID of the projectile.

[chrome mantle]

Put the cause statement 1st

if (cause === "entityAttack" && ...

Same with other if statements, put the cause first

[dusky magnet]

Now there are two errors. If use an entity like the trident that doesn't have the custom family, it sends this error:

"cannot read property 'hasTypeFamily of undefined at <anonymous>"

[chrome mantle]

**?.**hasTypeFamily

With that error, just add '**?. **' before the property/method

[dusky magnet]

I mean, it eliminated the error but the bullet entity that has the correct family isn't being detected.

[chrome mantle]

Hmmmm

[dusky magnet]

i just found a workaround.

I added a timer within the bullet entity that despawns it after 2 seconds. That way, it gets detected. and it does, so cool.

And gets rid of it.

[chrome mantle]

Nice one

I'd actually try map

const projs = new Map()

projs.set(projectile, player)

const source = projs.get(damagingProjectile ?? damagingEntity)
```idk ;-;

[dusky magnet]

No clue how that works in concept.
;-;

[chrome mantle]

Entity.prototype here is useable as a key cus entity === source can be used

Well, that's how objects in js behaves btw

[dusky magnet]

Hmm..
