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)
