Thanks, I will try it. I will check your game too, I like learning from examples. Em dom, 22 de out de 2017 18:14, Clément Bera <bera.clement@gmail.com> escreveu:
Hi Eduardo,
Your FFIStructures are not initialised (I thought this was solved in latest Pharo 7 ? Maybe not integrated yet). Run:
FFIExternalStructure allSubclassesDo: #rebuildFieldAccessors.
Then your code should work.
I wrote a simple game using Pharo/SDL2/Cairo and it works very well (50fps without problems, responsiveness is really good, etc.), the ReadMe includes how to run it on Ubuntu/Mac OS X/Windows, check here:

Let me know if you have other questions.

Hi, greetings!
I was trying out some examples from the Pharo By Example book on the latest development version of Pharo, and I wanted to create a stand-alone window for a simple game on Ubuntu. So I found out the openInExternalWindow method, the window appears but I get this error that I couldn't understand, and could not find any reference to it online. So I'm not sure if it's a bug.
The simplest way I found to reproduce it was:
'Hello' asMorph openInExternalWindow.
I'm using Pharo 7 on Ubuntu 17.10.
A copy of the stack:
ByteArray(Object)>>primitiveFailed: ByteArray(Object)>>primitiveFailed ByteArray>>integerAt:size:signed: ByteArray>>unsignedLongAt: SDL_KeyDownEvent>>windowID OSSDL2Driver>>convertEvent: [ event := self convertEvent: sdlEvent. event ifNotNil: [ eventQueue nextPut: event ] ] in OSSDL2Driver>>processEvent: in Block: [ event := self convertEvent: sdlEvent.... BlockClosure>>on:do: OSSDL2Driver>>processEvent: OSSDL2Driver>>eventLoopProcessWithoutPlugin [ self eventLoopProcessWithoutPlugin ] in OSSDL2Driver>>setupEventLoop in Block: [ self eventLoopProcessWithoutPlugin ] [ self value. Processor terminateActive ] in BlockClosure>>newProcess in Block: [ self value....
But it seems incomplete. Any more information I can provide?
Thank you.
