Activities/Reflection

Reflection

Reflection is a symmetry game. The goal is to create a reflective symmetry.

How to play Reflection

Click on the dots to change the colors until you have a reflective symmetry.

Did you know that you can share Reflection and play with up to 3 others?

• 

  Each time you play a new game, a randomly generated pattern is created.

• 

  You can also play with vertical symmetry

• 

  You can also play with bilateral symmetry

Credits

Reflections was written by Walter Bender and Reuben Caron as an example of how to migrate a simple Flash activity to Sugar.

Refexion.swf is part of a bundle of Flash games Reuben encountered at a deployment in Central America. The game is simply a grid of squares that change color when clicked (See the figure below).

The closest activity we could think of that had something similar (a grid of clickable elements) was Activities/Turtle in a Pond. We then:

1. made a clone of the activity
2. generated a new git repository for the project
3. changed the activity.info file to reflect the name of our new activity
4. changed the activity icon
5. changed the name of TurtlePondActivity.py to ReflectionActivity.py
6. changed the name of the Class defined in ReflectionActivity.py to class ReflectionActivity(activity.Activity)
7. removed the buttons we didn't need
8. edited game.py:

• we made the dots cycle through four colors rather than just two when clicked
• we removed the turtle and all code associated with moving it
• we added a line of symmetry
• we rewrote the rules for detecting end of game

All of this was done in less than 2 hours.

We then created an XO bundle, uploaded it to activities.sugarlabs.org and created this page in the wiki.

For Version 2, we added saving game state to the Journal, added a few more game options, and collaborative play.
