Interactable Objects: Episode 2 - with Interfaces Unreal Engine Blueprint Tutorial
Welcome to Episode 2 of our Unreal Engine Blueprint tutorial series, where we explore how to create interactable objects using interfaces in Unreal Engine 5 (UE5). This step-by-step guide will help you level up your game design skills by enabling players to interact with objects in the game world, affecting their character's health, mana, and the environment.
NOTE: If you want this to be applied to children of the ALS_Base_Character_BP, remove the "Get Player Pawn" node from the Target of "Increase Health" and other calls in the respective BP, and drag the "Other Actor" node from "Event ActorBeginOverlap" and connect it to the Target. For my implementation, I have it only affecting my player pawn and will show the difference in the next episode.
2nd NOTE: If your goal is to have the object alway retrigger when leaving the overlap, you do not need the 'DoOnce' node. But if you want to customize to only allow it to be retrigger-able in certain events, use the 'DoOnce' and tie the reset to those certain events. The begin and end overlaps only trigger one time naturally, but for something like this, you may want the control to only trigger one time and not again, or may want to retrigger only after leaving and interacting with something else in your game.
In this tutorial, you will learn how to:
-Modify and implement the CharacterInfo_Interface that we created in the previous episode in Unreal Engine 5
-Set up player-triggered overlap events without casting in UE5 Blueprint
-Duplicate and modify blueprints for various game interactions, including health and mana management
