| # Supported Events |
|
|
| The Event System supports a number of events, and they can be customized further in user custom user written Input Modules. |
|
|
| The events that are supported by the Standalone Input Module and Touch Input Module are provided by interface and can be implemented on a MonoBehaviour by implementing the interface. If you have a valid Event System configured the events will be called at the correct time. |
