Touch.deltaposition

Touch에서 position, deltaPosition은 둘다 Vector2

Touch.deltaPosition

public Vector2 deltaPosition;

Description

The position delta since last change in pixel coordinates.

The absolute position of the touch is recorded periodically and available in the position property. The deltaPosition value is a Vector2 in pixel coordinates that represents the difference between the touch position recorded on the most recent update and that recorded on the previous update. The deltaTime value gives the time that elapsed between the previous and current updates; you can calculate the touch's speed of motion by dividing deltaPosition.magnitude by deltaTime.

Touch Properties

altitudeAngle	Value of 0 radians indicates that the stylus is parallel to the surface, pi/2 indicates that it is perpendicular.
azimuthAngle	Value of 0 radians indicates that the stylus is pointed along the x-axis of the device.
deltaPosition	The position delta since last change in pixel coordinates.
deltaTime	Amount of time that has passed since the last recorded change in Touch values.
fingerId	The unique index for the touch.
maximumPossiblePressure	The maximum possible pressure value for a platform. If Input.touchPressureSupported returns false, the value of this property will always be 1.0f.
phase	Describes the phase of the touch.
position	The position of the touch in screen space pixel coordinates.
pressure	The current amount of pressure being applied to a touch. 1.0f is considered to be the pressure of an average touch. If Input.touchPressureSupported returns false, the value of this property will always be 1.0f.
radius	An estimated value of the radius of a touch. Add radiusVariance to get the maximum touch size, subtract it to get the minimum touch size.
radiusVariance	This value determines the accuracy of the touch radius. Add this value to the radius to get the maximum touch size, subtract it to get the minimum touch size.
rawPosition	The first position of the touch contact in screen space pixel coordinates.
tapCount	Number of taps.
type	A value that indicates whether a touch was of Direct, Indirect (or remote), or Stylus type.
