Problem with loot spawning at 0.0.0 location..

[catz111]

I added some weighted rng loot drops to my game but for some reason i can’t make it spawn where my enemy die. I have the loot functions on an actor component then by adding the actor component to my base enemy BP seems to work pretty well. The loot drops as i set it only not on the location on which it is set (location of the enemy).

It looks like this on the actor component

I was trying to get world location or actor location from there to my base enemy bp but it didnt work. I had some success on putting the drop logic directly on the enemy bp but the rng loot didn’t work… Can i somehow get the location of the mesh of the enemy bp or capsule component and use that as a drop location on this actor component somehow? I awso try to "set the location " in the enemy bp and then getting it on the actor component but the loot aways just drop at 0.0.0 location

Is by any chance the Destroy node executing before DropLoot?

[catz111]

No it is not

Maybe i do not access properly the enemy base bp from the actor component where i try to get the location ?

[pezzott1]

Where / how are you assigning a value to MainEnemy?

[catz111]

Is just a reference to my main enemy bp. From which all my enemy’s are child of. Not sure what else to do. I was trying to SET a capsule or mesh location on this base enemy bp and then was getting this location on the actor componenent but it didnt work…

When i print string the world or actor location of this main enemy bp i get 0.0.0

@catz111

Is just a reference to my main enemy bp

Yes, got that. It must be set somewhere.

I assume LootTable is a component assigned to BP_MainEnemyClass. Right? So there should be a GetOwner → Cast<BP_MainEnemyClass>() → MainEnemy in BeginPlay.

GetActorLocation node returns a zero vector if the reference is null. So we need to check if its being set correctly before anything else.

yes this correct…

Where exactly do i need to cast to main enemy bp ? On beginn play in the actor component ?

@catz111

On beginn play in the actor component ?

Yes.

@pezzott1

GetOwner → Cast<BP_MainEnemyClass>() → MainEnemy

[catz111]

Hmm im not sure if this is right but its working still have 1 bug with it. It picks only 1 actor when i have 10 and spawns all the loot only on this one actor… I guess my setup isnt right yet…

Here is how this looks like when i have many enemy’s and by killing them all the loot drops only on the 1 guy and stacks on him…

This:

I try that but it didn’t work … i get an error on the owner

then i can plug the main enemy there and the error is gone but the loot start spawning again at 0.0.0

[pezzott1]

The node should say Target is Actor Component not Target is Actor:

Make sure you add this in the LootTable component.

[catz111]

Oh yeah i didnt see that. Just changed it to “owner” actor component and now everything works as it should lol… Thx that was pretty easy acctually

[pezzott1]

Great!

Now that its working, if all you want is the actors location you can delete all the above and just do:

If you need to access anything specific to a class then you do need to cast.

[catz111]

lol yeah even this works now … I previously did exactly this as the very first thing and it didn’t work. But i had “get owner actor” and not “owner actor component”. That would have fixed it from the beginning. Oh well now i learned something new so hopefully i don’t make this mistake again. Thx a lot
