Credits

Tweener was built and is maintained by a core group, with the help of several different people. Here's a listing of them.

Core team

• Zeh Fernando created the original Tweener version and still maintains the core code tightly secured under his mattress.

• Nate Chatellier ported the original AS2 code to AS3 beginning at version 1.14.17 or so. Versions today are updated in sync, and Nate contributes with bug reports, fixes, and suggestions.

• Arthur Debert contributed with many ideas, bug reports and fixes, as well as AS3 guidance on porting issues.

Other versions

• Baluta Cristian has ported and maintains a haXe version of Tweener.

• Yuichi Tateno (aka secondlife) has ported and maintains a JavaScript version of Tweener.

• Benjamin Harling created the Python version of Tweener.

• Wesley Marques maintains a C++ version of Tweener.

Translation contributors

• Celina Uemura has translated the documentation to Brazilian Portuguese.

• Ayu Tada maintains the Japanese version of the documentation.

Example file contributors

• Igor Costa contributed with Flex examples.

Indirect code contributors

Tweener uses parts of code written by other people (read more about it on the License page). People listed here do not necessarily endorse Tweener; it just means we used code created by them.

• Robert Penner is the one who created the original easing equations. Without him Tweener probably wouldn't exist. He also created the optimized pointOnCurve algorithm used on the bezier point calculations.

• Mario Klingemann (also known as Quasimondo) wrote a great class to manipulate the object color matrix in ActionScript. Parts of his class are used on Tweener to create the special color transitions.

Suggestions and other thanks

These people do not necessarily endorse Tweener either, but they have contributed to the project in one way or the other so here's some acknowledgment. Thanks!

• Paulo Afonso suggested ideas that led to the creation of the addCaller method.

• Francis Turmel provided some great suggestions and a lot of inspiration driven from during long emails discussions, as well as several code fixes and suggestions.
