Type: Touch

The Touch type represents a physical interaction between a person and a piece of hardware, are are commonly provided by interactive data nodes, such as the LED Processor Input Node. Touches store three dimensions of interaction data plus a radius, although most Touches will only have an x and y coordinate along with a radius. Touches also track additional state information about themselves, including the time at which the touch was created, the vector on which the touch is moving (if the touch is moving), and its initial location.

Constructors

There are no constructors exposed by this type. Use a Simulated Touch Node to create a simulated touch.

Parameters

	Type	Details
uuid	String	Note: The parameter is read-only. The unique UUID assigned to this touch upon its creation.
id	Number	Note: The parameter is read-only. The sequential ID assigned to this touch upon its creation. This number is increased by 1 for every new touch that is created by Waltz.
initialLocation	Point	Note: The parameter is read-only. The initial location at which this touch was created.
currentLocation	Point	The current location of this touch. Setting this value will update the lastUpdatedMillis automatically.
radius	Number	The radius of this touch, in pixels. Setting this value will update the lastUpdatedMillis automatically.
vector	Point	Note: The parameter is read-only. The vector upon which this touch last moved.
angle	Number	Note: The parameter is read-only. The angle, in degrees, of the current vector's z axis.
creationTimeMillis	Number	Note: The parameter is read-only. The time, in milliseconds, at which this touch was created.
lastUpdatedMillis	Number	Note: The parameter is read-only. The time, in milliseconds, at which this touch was lasted updated.

Functions

	Arguments	Returns	Details
invalidate()		Void	Marks this touch as invalid by setting its lastUpdatedMillis to 0.
equals(t)	Touch t - A touch against which to compare equality.	Boolean	Compares two touches to determine if they represent the same touch with matching uuid, id, creationTime, initialLocation, and currentLocation.
