Unity3D working on SDL, Wayland and Mir support

By - | Views: 24,557

The folks Unity3D are currently doing a "HackWeek" when they work on special projects. It looks like the Linux team are working on using SDL instead of X11 directly which will bring Mir & Wayland support amongst other things.

For those that don't know: X11, Mir and Wayland are what allow you to see windows, drag them around and generally do everything on your Linux computer. X11 is really old and Wayland/Mir will eventually replace it.

I follow Unity developer Na'Tosha Bard on twitter, and it has been fun to see the progress on it, here's what they have done so far!

I love that Unity developers do things like this. SDL support should make things like multiple monitor handling much better. That is something I am especially keen for, as multiple monitor handling in a lot of Unity games is often really poor. SDL could also help them improve things like gamepad/controller support too.

Worth noting that these changes may not end up in the official Unity builds, but we can hope it all works out.

Yeah, that was supposed to be in, I accidentally duplicated one. Fixed.

Nice news! More comfortable and efficiency are the developping tools on Linux, more developpers will develop on this platform.

They should also stop collecting user data without their explicit consent.
Hopefully you guys haven't forgotten. :)

What is the difference between SDL and X11?

Quoting: TemplateRWhat is the difference between SDL and X11?

One is a complete windowing system that is based around a 20-something year old design (x11), one is a toolkit that can generate windows and handle input for multiple windowing systems and is substantial more modern in it's design (sdl)

SDL in an abstraction layer with multiple backends. It provides access to audio, keyboard, mouse, joystick, and graphics hardware. X11 is a windowing system that functions as a backend for SDL, but also can be used directly. They are moving away from using X11 directly to SDL abstraction, which allows it to work on other backends such as Wayland.

I especially hope that SDL itself will profit from it (bugfixes/performance wise). It it in my opinion still not very good. For example even Trine 1 is unplayable even on lowest settings (extremly ugly) on my intel laptop (<10 fps), which should not be the case for such a simple sidescroller imho.
Not sure if it is good for a game engine to put a additional layer between it and the system in general, but for unity I personally dont care much as long as it works better than before.

But if I'm not mistaken none of the current distributions is using any of the new display servers as a default yet. I hoped at least that Fedora 24 will use Wayland as a default, but unfortunatly it's still too unstable. Everything goes soooo slow.

That means, that SDL is much better then X11?
