# Setup

### Setup

Setting up **S.B.I. (Simple Basic Interactions)** is quick and easy. Follow the steps below to get your player character ready to interact with the world.

***

#### 1️⃣ Add the Interaction Component

Add the `AC_PlayerInteractions` Actor Component to your **Player Pawn** or **Character**.

This component handles all logic related to detecting and interacting with objects in the world.\

#### 2️⃣ Assign the Active Camera

You’ll need to assign your **active player camera** to the component. This is important because all interaction line traces originate from this camera’s forward direction.

* For **first-person** and **third-person** setups, this should be all you need!
* If you switch cameras during gameplay (e.g. cutscenes, aim mode, etc.), make sure to update the component with the new active camera.\

#### 3️⃣ Adjust Distance to Interact (Optional)

Inside the `AC_PlayerInteractions` component, you can modify the `DistanceToInteract` float. This value defines how far the interaction line trace will reach from the camera.\

***

#### 4️⃣ Top-Down Games (Optional)

If you're working on a **top-down** or camera-independent setup, you can customize the `FindInteractions` function inside `AC_PlayerInteractions` to suit your input direction or world location logic.

***

#### 5️⃣ Input Setup

By default, the interaction system uses an **Enhanced Input Action** called `IA_Interaction`, which is mapped to the **E key**.

> ⚠️ If you're already using `E` for other gameplay elements, don’t forget to remap the key or reassign your input bindings.
