You know like...a sand castle in a sandbox or something? Basically a setup to play gym environments

Why?

I like creating gym environments. But I want to play inside them too. It would be pretty cool to create simple games in pure python with like a couple hundred lines of code; even if it is an ASCII-esque game.

Rendering games as "rgb_array" is nice if you have all the information to do it, but most of the time I don't have it, nor do I "care" enough.

How will the game work?

My intent is that environments will use several conventions(?) (or is it grammatically better to say "semantics") which a generic wrapper will use. These are:

• get_board() - returns a numpy array of 2 or 3 dimensions. If 2 dimensions then it displays the "height x width", if 3 dimensions then it displays "layers x height x width", especially if items can occupied the same position.
• get_info() - provides the mapping from the numpy array to the icon which is displayed or the sprite which is used

Types of games to target:

• Games which run based on a "frame-rate" (e.g. atari-esque)
• Games which wait for input (e.g. solving a path finding environment)

Examples

See example/ folder. The various scenarios and approaches are shown there:

• blocking: simple2x2 whereby you navigate a maze
• random: movement - a demo example whereby the agent moves around at random
• async: catch - a pseudo-async example for an atari-esque game

Goals and Milestones

• Ascii wrapper
• Ascii wrapper with colorama
• Pyglet with ascii
• Pyglet with sprites
• Kivy for cross app development. Need to remove any numpy or gym dependencies to build it better.

Who knows!
