# Power Event

{% hint style="info" %}

1. Using the UnityEvent feature on each controller will allow you to add multiple event types, see the demo scene for a clear example on this.
   {% endhint %}

```csharp
void ActivateGenerator()
{
     rumbling = true;
     activateGenerator.Invoke();
}

void DeactivateGenerator()
{
     rumbling = false;
     deactivateGenerator.Invoke();
}
```

{% hint style="info" %}
The events below run the:

* Activate Generator script
* Start an audio effect parented to the object (3D generator sound)
* Turns the red light off
* Turns the green light on

The opposite happens in the deactivate section
{% endhint %}

![](/files/7m8C9EGjdl5XtcqOQr61)

* Below is the script that gets activated by the event

![](/files/iHlpYZQeyQDioKBqVbKs)

```csharp
    public class ActivateGenerator : MonoBehaviour
    {
        [SerializeField] private Renderer[] thisMaterial = null;
        private string emissionName = "_EMISSION";

        [SerializeField] private GameObject[] lights = null;

        public void PowerLights()
        {
            foreach (GameObject lightObjects in lights)
            {
                lightObjects.SetActive(true);
            }

            foreach (Renderer emissiveMaterial in thisMaterial)
            {
                emissiveMaterial.material.EnableKeyword(emissionName);
            }
        }

        public void DeactivateLights()
        {
            foreach (GameObject lightObjects in lights)
            {
                lightObjects.SetActive(false);
            }

            foreach (Renderer emissiveMaterial in thisMaterial)
            {
                emissiveMaterial.material.DisableKeyword(emissionName);
            }
        }
```
