# Receive Event

To react to an event (like opening a door, updating UI, or playing a sound), you need to **Subscribe** (Bind) to the Simple Event System.

> 📍 **Where to put this?**\
> The best place to bind events is usually inside **Event BeginPlay** (for Actors) or **Event OnInitialized** (for Widgets).

***

### Step 1: Get the System

First, we need to get a reference to the system component.

1. Right-click on your graph.
2. Search for **Get Simple Event System**.
3. Place node on the graph.

***

### Step 2: Assign the Dispatcher

Now, we bind a custom event to the system's dispatcher.

1. Drag off the blue return pin from Get Simple Event System.
2. Search for **"Assign Event System Dispatcher"**.
3. This will create two nodes:
   * `Bind Event to Event System Dispatcher` (The subscription).
   * `Custom Event` (Where your logic goes).

{% hint style="info" %}
**Tip:** You can use `Create Event` node to bind separate **Function** instead of `Custom Event`.
{% endhint %}

### Step 3: Set the Tag Switch

By default, you will hear **every single event** in the game. You probably don't want that.

1. Locate the **Event Tag** input on the `Bind Event` node.
2. Get the `Switch on Gameplay Tag` node.

In the Details panel of Switch node select the specific **Gameplay Tag** you want to listen for (e.g., `TriggerOverlap.Start`).

***

### Step 4: Handle the Logic

Now, connect your `Bind Event` node to `BeginPlay`.\
Then, add your game logic to the `Custom Event` node.

**Example:**

* **Event:** TriggerOverlap.Start
* **Logic:** Print String "Hello World".
