General Questions
Q. What is ZDoom?
A. ZDoom is, essentially, an advanced source port for Doom. However it doesn't just support Doom/Doom II, it also has support for Hexen, Heretic, and Strife. For more information see ZDoom For Dummies or just browse the Wiki yourself.
Q. Is it free?
A. ZDoom the port itself is free to download and use. However you need an IWAD to be able to play it. To get a hold of an IWAD you have to buy the game. The Doom's Collectors Edition is probably the best buy as it includes Doom, Doom2 and Final Doom IWADs. Heretic Hexen and Strife are sold seperatley. The most commonly used IWAD is Doom2.
Q. When will the next version of ZDoom be out?
A. "When it's done". Randy has a life to live beyond Zdoom believe it or not, so you should be patient. Asking on the forums will not help.
Q. Who develops ZDoom?
A. Randy is the creator and main developer of ZDoom. Graf Zahl also develops ZDoom alongside Randy using Subversion Repository.
ZDoom Specific Questions
Q. How do I do X?
A. Before asking a question regarding editing or editing ZDoom, browse this Wiki and try to find your answer. If you still can't find anything post on the forums.
Q. Will ZDoom implement high-color or GL graphics?
A. Randy considers high-color graphics a low priority. However, GL graphics have already been implemented in ZDoomGL (by Timmie) and GZDoom (by Graf Zahl), which also supports 3D floors and dynamic lighting.
Q. Cajun bots are too stupid. Why?
A. Not enough effort was put into the Cajun bots to make them more versatile. Randy has no current plans to fix or improve the bot code.
Q. ZDoom won't run on my system. Why?
A. There are several factors contributing to this. Here is one:
- If you are running on a laptop with an ATI Rage Mobility video card, you must lower your graphics acceleration settings in Windows.
If you have any other issue that is specific to your system, you can try asking for help in the ZDoom forums. Chances are if you're having problems somebody there can help you, and you may end up contributing to ZDoom's development by reporting a previously unknown bug.
Q. I found a bug in ZDoom! What should I do?
A. First of all make sure you're using the latest version of ZDoom. If you are, head over to the bugs forum, search the forum to see if a similar bug has not been found and then post a new topic if one is needed. Remember to include what you did to find the bug and what wads you were using at the time.
Q. Will you add or will there ever be *insert feature here*?
A. Request it in the forums. Just because you ask for it doesn't mean you'll get it!
Troubleshooting
Q. My screen is badly garbled. How can I fix this?
A. The cause for this is that you are using attached surfaces. This fix is really only needed for systems running Windows NT 4, and has been changed to an auto-detection as of 2.0.90. Keep in mind that this also happens if you have ZDoom and ZDoomGL in the same folder, so keep the two separate.
Q. Sounds are clicking badly; Zdoom freezes when a lot of sounds are played. How do I fix this?
A. Once again, there are several factors contributing to this-
- Try to increase the buffer size in the sound menu to at least 100 ms.
- Do you have another application using sound in the background? If possible, try to close other applications using sound (ex. Winamp) before playing.
- You may need to reinstall or update your sound card drivers.
- You may need to upgrade your DirectX. The latest version is 9.0c.
Q. I accidently checked the box which prevents Zdoom from letting me pick my IWAD! How do I get it back?
A. 1.Open your zdoom.ini file with any text editor.
2.Locate the line saying "queryiwad = false".
3.Change the "false" to "true"
Hey Presto, next time you start ZDoom, it'll reappear.
From version 2.1.2 and up you can force the dialog to appear by holding SHIFT during startup.
