  - Do not use "wysiwyg" when editing, it seems to break the format. Only work with the "textarea".
  - This FAQ reflects the latest stable version, references to upcoming versions should be clearly highlighted and removed with the release.
  - Write short and to the point.
  - Pay attention to consistency (for example, internal links to other wiki articles are prefixed with wiki/…, links to forum posts always with a date, …).
  - It looks better if there is a little space between the text and the image by inserting a blank line before and after the image macro. Images from the source game can be inserted with "[[Image(source:ps/trunk/<PATH FILE>@<REVISION>, < ADDITIONAL OPTIONS, e.g., inline/size/position/...>)]]". Adding a revision number ensures that this particular image is shown at all times.
  - NOTE: write a comment about your change so that it is easier to see from the history what the change was about. Even a single word is better than nothing.

By decreasing `view.zoom.min` you can zoom in closer, and by increasing `view.zoom.max` you can zoom out further. The default values of the game are set in the [[source:ps/trunk/binaries/data/config/default.cfg@27104#L577|default.cfg]]. With a larger zoom max more things have to be drawn, expect reduced performance, especially on weak GPU's.

__Computation lag:__[[BR]]
This is a common problem with the game. The main factors that determine how smoothly 0 A.D. runs are primarily the CPU speed, the amount of RAM available, the type of graphics card in your computer, the game options and the game's setup settings you choose. If you are unhappy with the performance of the game on your computer, there are some things you can do to improve it, but be aware that the lag for large battle scenes will likely be noticeable regardless of your settings or PC specifications.
1. ''Before Launching 0 A.D.''
 - It is recommended to close all other applications as they consume resources and affect the overall performance of the system.
2. ''Game Options''
 - `Antialiasing`: `FXAA` has no performance impact, `MSAA` only for good GPU's. Must be disabled for macOS, see [[FAQ#macOS|Platform-specific]].
 - Set `Model Quality` to the lowest value.
 - Disable `Shadows` or choose `Low Quality` from the dropdown menu and a low value for `Cutoff distance`.
 - Enable `Water Effects`, but disable `High-quality water effects` and `Water refractions`.
 - `Texture Quality` - `Low`
 - `Texture anisotropic filter` - `1x`
3. ''Game Setup''
 - Play on smaller maps and limit population to 600 units across the map for all players. Rendering, simulation (for example gathering / attacking), and the pathfinder all have an impact on performance.  If you have more units, more things need to be drawn, which affects rendering, more things to calculate for unit activity affects simulation, and larger map sizes cause longer paths, which affects the pathfinder.

      {{{#!div class="important" style="background: #ffd"
  **NOTE:** Multiplayer games are calculated on all computers simultaneously, with the slowest PC determining the game speed. If your computer is a bit outdated, you should follow the guidelines listed above. This might make the game faster for everyone. 
  By toggling the [[EngineProfiling#In-GameProfiler|wiki/In-GameProfiler]] with `F11 or Alt+F11` you can see which processes take the most time, often it is the `render` process and in large battle scenes also the `sim update`.

>Frame rate - CPU and GPU workload
    }}}
    {{{#!td style="border-right:none;padding-left:0.5em"
1. Every frame that is calculated by the GPU is "prepared" by the CPU, one of them will limit your frame rate (FPS). When you select graphics effects, you create additional workloads for your GPU and CPU, causing your framerate to drop. Current PCs are mostly CPU limited in 0 A.D.. Since graphics effects mostly affect the GPU, you can (on newer PCs) choose the higher graphics effects without sacrificing performance.
2. Thermal throttling is especially known for mobile PCs. If the hardware gets too hot, it throttles its performance until the hardware cools down again. Therefore, a limited but constant frame rate is usually better than a frame rate that fluctuates due to thermal throttling.
3. VSync will also limit the framerate to the framerate of the monitor.

>No sound, no audio, or 0 A.D. is the only app with sound
    }}}
    {{{#!td style="border-right:none;padding-left:0.5em"
There are some settings in the game related to volume levels. From the main menu, click Settings, Options, Sound. 

If you start 0 A.D. then connect a sound device or plug in an audio jack, then usually it is necessary to configure your operating system to use that new sound device as the default sound device and restart 0 A.D. in order for it to be detected. If you often do that on Linux with pulseaudio, consider enabling "allow-moves" in the OpenAL configuration. More on the configuration is later in this answer. Note that the [https://github.com/kcat/openal-soft/commit/c135629eae544b0e7785803b98987c1ab1eb95ca default setting changed] between release version 1.19.0 and 1.20.0, to remove a workaround for a KDE bug related to the primary audio device. Thanks to Dunedan and seeh for the [https://wildfiregames.com/forum/topic/108002-what-kind-of-audio-system-does-0-ad-use/#comment-555709 idea].

Assuming that sound works for other apps while 0 A.D. is not running then troubleshooting the sound output of 0 A.D. likely involves troubleshooting OpenAL on your system. This is because 0 A.D. uses the OpenAL sound system for audio output. It can be useful to test other games that use OpenAL, such as chromium-bsu, supertux, supertuxkart, dustracing2d, scorched3d, lugaru, warzone2100, ioquake3, and rtcw.

Check the OpenAL configuration, which on Linux and Mac is stored at {{{/etc/openal/alsoft.conf}}}, and on Windows is stored in {{{%AppData%\alsoft.ini}}}. If it does not already exist then download [https://raw.githubusercontent.com/kcat/openal-soft/master/alsoftrc.sample alsoftrc.sample], rename it to the appropriate name for your OS and store it in the correct location, listed earlier.

Ensure that the correct "driver", also known as "audio backend", is being used by OpenAL. There are reports from users where unexpected drivers were used by OpenAL, for example trying to use jack, failing, next using alsa instead of Pulseaudio. The only documentation easily found about the OpenAL configuration is in the comments within alsoft.conf. When referencing drivers in the OpenAL configuration, use the name of the audio backend within the quote marks at [https://github.com/kcat/openal-soft/blob/master/alc/alc.cpp#L199 alc.cpp]. 

Recommended OpenAL drivers configuration statement:
* Linux: {{{drivers = pulse,alsa,}}}
* Mac: {{{drivers = core,}}}
* Windows: {{{drivers = wasapi,}}}

Note that OpenAL driver availability depends on your operating system and compile-time choices for your copy of the OpenAL library. The [https://github.com/kcat/openal-soft#utilities openal-info] utility lists detected devices. If you are using Linux then openal-info may be available for your distribution in a package called, for example, openal-info.

For further help with OpenAL, contact the OpenAL developers via the means specified on their [https://openal-soft.org/ website].

Note that OpenAL can only work as well as the audio backend or driver that it is configured to use, so that is another area to consider during troubleshooting.

    {{{#!td style="border-right:none;padding-left:0.5em"
There are several possible causes of this error message. Often it is caused by an incorrect network configuration on the host side. The host must ensure that UPnP is enabled at the router or UDP port 20595 is forwarded to their correct private IP address.

If you see this error when attempting to connect to all hosts using STUN then you should [https://wildfiregames.com/forum/topic/106679-failed-to-connect-to-server-error-solved/#comment-548245 check] whether you have an Internet connection that uses Carrier-Grade NAT. If you discover that you have CGNAT then you may be able to ask your ISP if you can subscribe to "public IP address service". See the forum thread for more information. An alternative solution is to use a VPN to play 0ad online.

Although the above are the most common causes, there are numerous other scenarios that can cause this symptom. Here are some examples.

- [https://www.purevpn.com/blog/double-nat/ Double-NAT] networking configuration: Troubleshoot and remove the unnecessary NAT device. This could be present client-side or host-side.
- Wireless network with too-high packet loss: try connecting with an ethernet cable instead.
- Intel Puma chipset in the modem or router causing too-high packet loss: replace the affected device.
- Inappropriate MTU used with a VPN causing loss of larger packets: should be fixed in 0ad alpha 27 and later.

    {{{#!td style="border-right:none;padding-left:0.5em"
Port forwarding is a way to make a computer on your network accessible to computers on the Internet, even though they are behind a firewall/router. This is commonly used when playing games or downloading files. If you have forwarded a port in your router settings, it is referred to as an open port. 0 A.D. uses UDP 20595 by default.

[=#LobbyModeration]We hope that you too want to support an enjoyable environment for everyone in the lobby. Please be aware of the conduct that is against the rules by reading through the [https://trac.wildfiregames.com/browser/ps/trunk/binaries/data/mods/public/gui/prelobby/common/terms lobby legal terms], especially the [https://trac.wildfiregames.com/browser/ps/trunk/binaries/data/mods/public/gui/prelobby/common/terms/Terms_of_Use.txt Terms of Use].

Lobby moderators watch the chat messages in the public lobby, game room names, and player names. Misconduct is punished with kicks, mutes or bans, typically on a reactive basis that may be delayed by hours. So, don't assume that the messages you sent just before being muted were the cause of the mute.

If you were simply kicked then you are able and allowed to reconnect to the lobby immediately. There are four English swearwords that cause the profanity filter bot to punish players. Initially, the bot will kick a user from the lobby for using profanity. With subsequent infractions the bot will mute a player for 2 days.

If you were manually muted or banned then it is usually intentional, and you can privately contact a lobby moderator, via the [https://wildfiregames.com/forum/ forum] or [https://www.wildfiregames.com/irc.html IRC chat], in order to ask about the reason for the mute/ban or engage in the appeal process. Please include in the message your lobby username, the approximate time and date that it happened, and a description of what happened.

You are not allowed to publicly complain about or even publicly discuss a ban. This helps to avoid spamming public chat with heated argument, and it ensures that there is an atmosphere conducive to a judicial process, Instead, the appeal process must be done through private communication with the lobby moderators.

Lobby moderators include admins, moderators and helpers. The current lobby admin is [https://wildfiregames.com/forum/profile/21426-user1/ user1].

It shows the current rank of your unit. The bar increases during combat by gaining experience points, once a certain threshold is reached, the unit moves up a rank. Depending on the type of unit (Healer, Ranged or Melee), certain values of the unit are boosted. Move the mouse cursor over the rank icon in the HUD to see the benefits of each rank.

    }}}
|----------------
    {{{#!td style="border-right:none;border-bottom: 1px dotted lightgrey;padding-left:0.5em"
There are three major types of damage:
1. `Hack` damage is usually inflicted in close combat by infantry or cavalry units.
2. `Pierce` damage is dealt by ranged units, either infantry archers or skirmishers or even special siege units such as bolt shooters.
3. `Crush` damage is caused by siege units such as catapults or rams.

The combat system works by matching the attack type with the resistance type.[[BR]]
In the image below, the `Gallic Mercenary Cavalry` has a `6.5 Hack` attack and the `Athenian Hoplite` has a `5 Hack` resistance level. The value in brackets is the effective resistance percentage, calculated like this 1-0.9^resistance level^ (1-0.9^5^ = 41%). For each attack made by the `Gallic Mercenary Cavalry`, 59% of their `Hack` attack will deal damage to the `Athenian Hoplite`.

[[Image(FAQ:attack_resitance.png,center,600)]]

Attack damage and resistance levels can be increased through technology upgrades, unit ranks or auras. Some units also have a bonus against certain unit classes, e.g. the `Athenian Hoplite` in the image above has a `3x` attack bonus against cavalry units.

Most effective are units that deal `Hack` or `Crush` damage, such as axemen, macemen, swordsmen, war elephants and rams themselves. Ranged units primarily deal `Pierce` damage, and are therefore ineffective against rams and siege towers.  Large numbers of female workers can also be utilized, but they have a low HP and should therefore only be used as a last resort.

Triggers can change the state of a unit directly, or they can be used to send the usual commands that users send through the user interface, see the wiki article for more information. Some standard maps that use triggers are `Danubius`, `Polar Sea` or `Jebel Barkal`.

>How to garrison my units in a building or ship through the `Scenario Editor`?
    }}}
    {{{#!td style="border-right:none;padding-left:0.5em"
There are **four** ways to workaround this limitation. A graphical interface solution depends on ticket #3008 (13/Jan/15).
1. Start the simulation in the `Scenario Editor` (aka `Atlas`), garrison your units, and then save the map while it is still running.
  - Related forum thread: [https://wildfiregames.com/forum/topic/77609-how-to-put-units-in-the-ship-in-the-editor/ How to put units in the ship in the editor] (19/Apr/22)

2. Edit the `.xml` file by inserting `Garrison` and `GarrisonedEntity`, see [[source:ps/trunk/binaries/data/mods/public/maps/skirmishes/sicilia_nomad_2p.xml@27589#L15623|skirmishes/sicilia_nomad_2p.xml]] for an example. This  can easily lead to unwanted errors if done incorrectly.

3. Open the `.xml` file and paste the following code into some `Script` tags, replace `HOLDER_ID` and `ENT1_ID, ENT2_ID, ENTN_ID, ...` with the `uid` numbers the entities have, you find them within the `.xml` file, e.g. `<Entity uid="3435">`. Open the map via Atlas and your units should be inside the structure. Save the map, open the `.xml` again and remove the `Script` tags and the code they contain.

{{{#!xml
<?xml version="1.0" encoding="UTF-8"?>
<Scenario version="7">
<Script>
  let cmpGarrisonHolder = Engine.QueryInterface(HOLDER_ID, IID_GarrisonHolder)
  if (cmpGarrisonHolder)
    cmpGarrisonHolder.initGarrison = [ENT1_ID, ENT2_ID, ENTN_ID, ...];
</Script>
}}}

4. Alternatively, add a trigger script to your map that is programmed to garrison entities in specific structures when the map is started.
