====== Get Titan Quest Running on Centos 7 ======

For general installation instructions, [[http://www.gamersonlinux.com/forum/threads/titan-quest-guide.311/|follow this guide]]. ([[https://wiki.bondari.com/_media/linux:titan-quest-linux-guide.pdf|PDF archive]])

While trying to get Titan Quest: Immortal Throne running on my son's computer, I ran into a number of debug problems. To fix the first, related to ''libudev.so.0'' (install ''libgudev1'' if it's not already installed):

<code>$ sudo ln -s /usr/lib/libgudev-1.0.so.0 /usr/lib/libudev.so.0</code>

If your application is 64-bit, then run the following:

<code>$ sudo ln -s /usr/lib64/libgudev-1.0.so.0 /usr/lib64/libudev.so.0</code>

The other errors were as follows. Most, if not all of them, relate to sound.

<code>err:module:load_builtin_dll failed to load .so lib for builtin L"winepulse.drv": libpulse.so.0: cannot open shared object file: No such file or directory
err:module:load_builtin_dll failed to load .so lib for builtin L"winealsa.drv": libasound.so.2: cannot open shared object file: No such file or directory
err:mmdevapi:DllGetClassObject Driver initialization failed
err:ole:apartment_getclassobject DllGetClassObject returned error 0x80004005
err:ole:CoGetClassObject no class object {bcde0395-e52f-467c-8e3d-c4579291692e} could be created for context 0x1
err:dsound:get_mmdevenum CoCreateInstance failed: 80004005</code>

The problem is that Titan Quest is a 32-bit application, whereas the WINE-PulseAudio system is 64-bit. That's why sound doesn't work. To fix it, install the required 32-bit libraries:

<code>$ sudo yum install pulseaudio-libs.i686</code>

===== Colors and Textures =====

If you experience screwed up colors and textures, check the PlayOnLinux debug log for the following error:

''err:winediag:wined3d_texture_init The application tried to create a DXTn texture, but the driver does not support them''

To fix it, try installing the following 32-bit package:

<code>$ sudo yum install libtxc_dxtn.i686</code>

===== Firewall =====

I also found that firewalld was blocking multiplayer connections. To allow for LAN games, open ''firewalld'' (search for ''firewall'' in GNOME), switch to the **Protocols** tab, and add ''udp'' as a protocol. To make this change permanent, go to the //Options// menu and select //Runtime to Permanent//.

While you're here, to allow other games (such as Diablo II) to connect through the firewall, do the same for ''tcp''.

===== ALT Key =====

By default, holding down the ''ALT'' key while clicking the mouse will move the current window/application. The problem is, you need to ALT+click to pick up items in the game. To fix this problem in KDE Plasma, launch System Settings, then go to //Window Management//, and click the //Window Actions// tab. Change the modifier key from ALT to Meta. Done.

To fix this on XFCE, open //Settings//, browse to //Window Manager Tweaks//, and click the tab for //Accessibility//. Now change the key used to grab and move windows from ALT to something else (like Super).
