Does anyone have a C# version of this script? Leave a link?

Comment on Gestion de la mémoire by fafase

” On se croirait presque devant un traducteur automatique par moment”, c’est parce que par moment vous êtes devant un traducteur automatique.

Google fait la moitié du boulot, je fais l’autre moitié mais après une heure de relecture on est moi attentif…

Bon, a part ca, j’ai revu l’article, ca devrait être plus clair. SI ya encore des fautes, beh je ferais un troisième passage.

je confirme les propos de Tepec.
L’article est intéressant mais les fautes d’orthographes et de grammaires sont plus que gênantes (et je suis pas une grammar nazi). On se croirait presque devant un traducteur automatique par moment.
Ca mériterait une sérieuse relecture.

merci tout de même pour tout ce travail. Je ne comprend pas tout techniquement mais ca m’aide bien.

Comment on Memory Management by whydoidoit

On reflection it’s probably not easy to implement SGen because a whole bunch of things aren’t pinned properly…

And it’s been a part of Xamarin and Mono Touch forever. Quite frankly it’s appalling that standard programming practices create garbage collection bumps and forces one into structs and the challenges that lie within those.

A 2 generation GC would be a significant improvement (though not quite Windows .NET standards), at Unite 2012 I was told they couldn’t get SGen to work, though I can’t really think why that would be the case.

Please beware that the garbage collector used in Unity does NOT defragment the heap, as this article claims. That Mono is a managed language does not automatically guarantee protection against heap fragmentation – for that, you explicitly need a compacting garbage collector, which is more advanced than what Unity currently ships with.

I have experienced memory issues and apparent “loss” of memory when viewing the process from the Task Manager many times myself, and I also wrote extensively about my experiment on Unity Answers, please see here for more details:

http://answers.unity3d.com/questions/153050/memory-management-and-list.html

Mono shipped a Generational, Compacting garbage collector a long time ago. There is information about their newer GC here:

http://www.mono-project.com/Generational_GC

This garbage collection engine was introduced with Mono 2.8 as early as october 2010, see here:

http://www.mono-project.com/Roadmap_History

Unfortunately for us, Unity still runs on Mono 2.6. Yes, even in the Unity 4.x release cycle. So we have no compacting, generation garbage collection. Our garbage collector is hopelessly outdated, and you should all go vote for the Feature request on Unity Feedback so we can get this friggin’ thing updated already:

Comment on Finite State Machine Tutorial #1 by whydoidoit

It just lets you collapse the region in the editor to make viewing the source easier…

Can I ask about the #region tags around Sleeping?

Does including the region tags allow the prefixing of the tag to the functions e.g. Sleeping_Update?

Or is it just a method to keep relevant code together?
