Detailed Description
Rotation gesture, also known as twist gesture This gesture is performed by moving two fingers around a point of reference in opposite directions
NOTE: it is recommanded to set ResetMode to GestureResetMode.NextFrame for this gesture
Member Function Documentation
§ CanBegin()
|
protectedvirtual |
This controls whether or not the gesture recognition should begin
- Parameters
-
touches The active touches
Reimplemented from GestureRecognizer.
§ GetRequiredFingerCount()
|
protectedvirtual |
Return the exact number of active touches required for the gesture to be valid
Implements GestureRecognizer.
§ OnActive()
|
protectedvirtual |
Method called on each frame that the gesture recognizer is in an active state
- Parameters
-
touches The active touches
- Returns
- The new state the gesture recognizer should be in
Implements GestureRecognizer.
§ OnBegin()
|
protectedvirtual |
Method called when the gesture recognizer has just started recognizing a valid gesture
- Parameters
-
touches The active touches
Implements GestureRecognizer.
Member Data Documentation
§ MinDOT
| float RotationGestureRecognizer.MinDOT = -0.7f |
Rotation DOT product treshold - this controls how tolerant the twist gesture detector is to the two fingers moving in opposite directions.
Setting this to -1 means the fingers have to move in exactly opposite directions to each other. this value should be kept between -1 and 0 excluded.
§ MinRotation
| float RotationGestureRecognizer.MinRotation = 1.0f |
Minimum amount of rotation required to start the rotation gesture (in degrees)
Property Documentation
§ RotationDelta
|
get |
Get rotation angle change since last move (in degrees)
§ TotalRotation
|
get |
Get total rotation angle since gesture started (in degrees)
Event Documentation
§ OnRotationBegin
| EventDelegate<RotationGestureRecognizer> RotationGestureRecognizer.OnRotationBegin |
Event fired when the rotation gesture starts MinRotation MinDOT
§ OnRotationEnd
| EventDelegate<RotationGestureRecognizer> RotationGestureRecognizer.OnRotationEnd |
Event fired when the rotation gesture is finished TotalRotation
§ OnRotationMove
| EventDelegate<RotationGestureRecognizer> RotationGestureRecognizer.OnRotationMove |
Event fired when the rotation angle has changed.
Query RotationDelta to get the angle difference since last frame Query TotalRotation to get the total angular motion since the beginning of the gesture RotationDelta TotalRotation
