Drastically improving the messageNotUnderstood title

Hi guys As I exposed newbies to our wonderfull debugger I think that we should change MessageNotUnderstood: Class>>#message into an instance of Class did not understand message To me this simple change would have a HUGE impact on making the debugger first contact a lot more friendly. Any taker? I'm off with a company today. Stef --

Thanks Sven. I completely missed that. However digging in, it seems only the Pi version got an API. The PC versions have no official API, although Forge seems to be the default community one by reverse engineering the obfuscated libraries each time Minecraft is released. Dimitris, thanks for the reminder of Redline Smalltalk. That seems a good candidate for running Smalltalk from a Java application.

That looks like the best option alternatively you can use JNIPort that allows to run Java libraries from Pharo. There is also redline smalltalk that is a Smalltalk that runs on top of the JVM. Python also has a very good implementation running on JVM called Jython it can not only use Java libraries but even regular Python libraries .

pondering Smalltalk scripting in Minecraft

by Ben Coman

Minecraft is immensely popular. For teaching programming (to kids) via Minecraft, the first option is Java, but that might be a bit heavy for a pre-teen. A few lighter options are Lua via Computercraft [1] and Javascript via Scriptcraft [2]. I've tried Computercraft and its quite interesting the way it simulates real-life computers and drones, but the drone works slowly so my kids end up doing things faster themselves. I am in the initial stages of trying Scriptcraft (with Spigot server) and making walls, buildings etc is fast, so hopefully my kids will see value in using these superpowers. But then I wondered whether it might be possible for SqueakJS and PharoJS to interface with Minecraft via the Javascript engine. I was interested to discover that the JVM comes with a Javascript engine built in [3], "Rhino" [4] for JVM7 and faster "Nashorn" for JVM8 [5]. So I thought I would just seed the idea in the community to see if anyone might be interested to pursue this. It really would be fantastic to use our environment to make mods for Minecraft. (The actual plan for world domination is to build some assets and experience with minecraft, and then migrate to a pure Smalltalk 3D client and server with GPU backends when that becomes available -gnomes) Or maybe it would be better to use JNIPort[6] or JavaConnect[7] or something else. cheers -ben [1] http://www.computercraft.info/2016/04/01/computercraft-and-computercraftedu… [2] http://scriptcraftjs.org/ [3] https://github.com/walterhiggins/ScriptCraft/blob/master/docs/Using-Java-AP… [4] https://jaxenter.com/scriptcraft-hacking-minecraft-for-kids-105467.html [5] https://www.infoq.com/articles/nashorn [6] http://smalltalkhub.com/#!/~JNIPort/JNIPort/ [7] http://www.squeaksource.com/JavaConnect
