Context: I am trying to create a basic inventory system that has 5 slots and can pick up the BP_Item one by one (no multiples, just single items), and then drops it one by one too. I went through a lot of videos and forum questions around the same, and figured out a basic Actor Component that can h…

Data Assets, Tables simply put are organized data containers. I treat them like a database. Items are assigned an ID that’s used to lookup the data. For example I use GamePlay Tags to define what a “thing” is. My interaction system gets the ID and reads it to determine the Type of item, what data t…

My Inventory stores flat data (Item quantities) for bagged type items (Ammo, meds, grenades etc). For slotted items I use a named actor object reference. [image] Every slot that uses an Actor obj ref is a spawned and attached actor. If not empty it’s a visible actor attached to the characters. E…

Took me a while to understand this system, but I’m finally there. Your solution about using more data tables instead of one big one is what I am trying out. I was finally able to spawn items replicating the same blueprint but taking data from the data tables, and am now figuring out the actor object…

[image] macwanna: am now figuring out the actor object ref inventory system. Because they are simple Actor Object References, not of specific class type, you have to use BP Interfaces to call events, pull data etc. There’s zero casting. [image] [image] [image] [image] [image] [ima…

I was able to pick up actor object references without casting or tags so far. The picking up part is on a line trace and the inventory system is an actor component on the BP_Player. Also my BP_Player is a pawn and the rest are all actors, so no character components present. Was trying to implement …

My setup uses the C++ implementation so I can use the Get Owned Gameplay Tags Interface. In your Build.cs file you have to add the dependency module GameplayTags [image] header // Fill out your copyright notice in the Description page of Project Settings. #pragma once #include "CoreMinimal.h"…

I was able to follow what you said about the C++ file stuff. Now, my system checks against the tags and only picks up the items that I want, based on how I make the tags. I used this blueprint for the BP_Player to check and then based on the boolean it picks up the object. [image] I was able to t…

I get this, without the message one. Same for when I do it with the Hit Actor. [image]

Look back over the C++. Verify the inclusion and implementation of the GameplayTagAssetInterface. Also, you need to add GameplayTags to the build.cs dependency… Pic 1
