Data:

INPUT_EVENT_UNKNOWN: Unknown event type (default).

INPUT_EVENT_MTOUCH_TOUCH: Event type for when there is new contact with the screen detected.

INPUT_EVENT_MTOUCH_MOVE: Event type for when contact with the screen is already detected, but the contact is changing position.

INPUT_EVENT_MTOUCH_RELEASE: Event type for when contact with the screen is removed.

INPUT_EVENT_MTOUCH_CANCEL: Event type for when a gesture is cancelled; a touch controller that is powered off could cause a cancel event.

Description:

One event type is received per touchpoint. For example, if you have two fingers in contact with the screen, you will receive two INPUT_EVENT_MTOUCH_TOUCH events. Similarly, if you remove two fingers from contact with the screen, you will receive two INPUT_EVENT_MTOUCH_RELEASE events, one for each finger. The touch-related events are identified individually through a contact ID.
