# Adding Trigger Event

### Setting Up Trigger Object

{% hint style="info" %}

1. Create a box or other 3D Object, make sure this object has a collider set to **IsTrigger**
2. Add the **CodeDeviceTrigger** script to that 3D object and add the keypad object to the inspector slot named **Keypad Object**. (The keypad object will have the script **CodeDeviceItem**)
3. Then set an input key you’d like to use for the interaction, by default set to **E**
