My character class is named BP_BasicInventor圜haracter in the image below, replace this cast with whatever your Character class is named after (the one that will hold your inventory items) We’ll get back to that later in the tutorial. Do note that “Add Item” is a function of our inventory character that we did not create yet. On Used event handles the response when a player presses “E”-key while hovering over an item. After creating the variable, compile and assign BP_InventoryActor as the default value. This variable holds the class that is created when this item is picked up by a player. This blueprint exists in the world and can be picked up by the player.Ĭreate a new variable “ Inventor圜lass” of type class’Actor’. Input MappingĪdd the following input mappings to your project. The mapped actions are available in Blueprint (We will implement these in the Character blueprint) This actor holds inventory data such as display name and could hold additional information like item weight and a thumbnail. Now create another Blueprint based on Actor and name it “ BP_InventoryActor“.
This actor is visible in the world and responds to On Used events. I’ve split the inventory and in-world objects into two separate blueprints, this requires a ‘mapping’ between the who which may be undesirable for very large projects, I intend to tackle this issue when moving to a more advanced inventory system (using DataTables) in future parts.įirst we create the blueprint classes so we can more easily move through the implementation in a single pass.Ĭreate a new Blueprint based on UsableActor and name it “ BP_PickupActor“. When dropping an item (“F”-key in tutorial) we spawn the actor back into the world. Last updated: 4.7 The Conceptīuilding on the UsableActor C++ class from part one we respond to On Used events (“E”-key in tutorial) by spawning a blueprint instance in the character’s inventory and removing the object from the world.
To keep the tutorial of a reasonable size I will not go in-depth for every node, you may of course ask any questions in the comment section!ĭownload : Tutorial2_Content (Includes post-process for item highlighting)īuilt for 4.0. It is expected that you have a basic working knowledge of Blueprint and Unreal Editor.
Please note that this tutorial was written based on the C++ Part 1 tutorial, some names or nodes may be slightly different if you work from the Part 1 Blueprint tutorial, but the concepts remain exactly the same.īuilding an inventory system is not beginner level. In this part I will show you how to build a basic inventory system to pickup, select and drop items from a player’s inventory. This is part two of a tutorial series, please first complete one of the following tutorials:
