# Airship Components

Most game logic is run through AirshipBehaviours. It is our equivalent to [Unity's MonoBehaviour](https://docs.unity3d.com/Manual/class-MonoBehaviour.html).

AirshipBehaviours offer [useful lifecycle methods](/typescript/airshipbehaviour/lifecycles.md). They are attached to [Game Objects](https://docs.unity3d.com/Manual/class-GameObject.html). 

{% code fullWidth="false" %}

```typescript
export default class ExampleAirshipBehaviour extends AirshipBehaviour {
	public greeting = "Hello, World!";

	public Start(): void {
		print(this.greeting);
	}
}
```

{% endcode %}

After the file is compiled, it can be added to a Game Object through the **Add Airship Component** menu

You should see your component added after selecting it:

When you run your game, this will print "Hello, World!"&#x20;
