A collection of tweening / easing functions.
Project description
PyTweening
A collection of tweening / easing functions implemented in Python.
Example Usage
All tweening / easing functions are passed an argument of a float from 0.0 (for the beginning) to 1.0 (for the end) of the tween:
>>> pytweening.linear(0.5) 0.5 >>> pytweening.linear(0.75) 0.75 >>> pytweening.linear(1.0) 1.0 >>> pytweening.easeInQuad(0.5) 0.25 >>> pytweening.easeInQuad(0.75) 0.5625 >>> pytweening.easeInQuad(1.0) 1.0 >>> pytweening.easeInOutSine(0.5) 0.49999999999999994 >>> pytweening.easeInOutSine(0.75) 0.8535533905932737 >>> pytweening.easeInOutSine(1.0) 1.0
The getLine() function also provides a Bresenham line algorithm implementation:
>>> pytweening.getLine(0, 0, 5, 10) [(0, 0), (0, 1), (1, 2), (1, 3), (2, 4), (2, 5), (3, 6), (3, 7), (4, 8), (4, 9), (5, 10)]
The getLinePoint() function finds a point on the provided line (even if it extends before or past the start or end points):
>>> getLinePoint(0, 0, 5, 10, 0.0) (0.0, 0.0) >>> getLinePoint(0, 0, 5, 10, 0.25) (1.25, 2.5) >>> getLinePoint(0, 0, 5, 10, 0.5) (2.5, 5.0) >>> getLinePoint(0, 0, 5, 10, 0.75) (3.75, 7.5) >>> getLinePoint(0, 0, 5, 10, 1.0) (5.0, 10.0)
