Re: [Pharo-users] how do you use scripts?

by David Boeren

I agree, I am not sure what you mean by a script here - can you elaborate? Personally, I think the environment erases a lot of the conceptual difference between a "script" vs. a "program".

Create ZipArchive from memory filesystem

by Markus Fritsche

Hello, is there a quick way to create a zip file from a memory filesystem that I can't see, or are the *Archive classes not compatible with the new filesystem api yet? Best regards, Markus

As my reference is Monkey-X for the core, here is the API: http://www.monkey-x.com/docs/html/API%20Reference.html One level above, one can do something like a port of Flixel to Pharo, as there is in http://devolonter.github.io/flixel-monkey/ Features Basic collisions between objects Easily generate and emit particles Camera system for split screen Resolution policies Create game levels using tilemaps Record and play back replays Text display and scrolling Pathfinding and following Tweening system Group objects together for simplicity Math & color utilities Easy object recycling I am also using Diddy https://code.google.com/p/diddy/ Features: Collections (ArrayList, etc.) Tweening Screen-Based Framework Sprites / Particles GUI (Buttons, Sliders, Windows) Serialization XML reader/writer Base64 encoding/decoding Tile Engine (Using the Tiled Map Editor) Now, there is also a new framework called ignition that was in the works for a year or two. http://www.playniax.com/ That's quite good. http://www.playniax.com/demos.html Sample game: https://www.youtube.com/watch?v=1ykGmat4Kyo#t=74 Now, one can think about making a Monkey-X based engine and scripting it with Pharo a bit like Kilon does with Blender.
