CubicBezierEasing

public CubicBezierEasing(float x1,
 float y1,
 float x2,
 float y2)

Creates a cubic bezier easing interpolator with the given control points. The start point of the cubic bezier curve is always 0,0 and the end point 1,1.

Parameters:

x1 - the x coordinate of the first control point in range [0, 1]

y1 - the y coordinate of the first control point in range [0, 1]

x2 - the x coordinate of the second control point in range [0, 1]

y2 - the y coordinate of the second control point in range [0, 1]

Method Details

interpolate

public float interpolate(float fraction)

Description copied from interface: Animator.Interpolator

Interpolate the given fraction and returns a new fraction. Both fractions are in range [0, 1].

Specified by:

interpolate in interface Animator.Interpolator

Parameters:

fraction - the percent (0 to 1) elapsed of the current animation cycle

Returns:

new fraction in range [0, 1]
