||= '''Issue''' =||= '''possible Solution''' =||
|| Crash when starting the game || Do you have any antivirus software running? Try disabling it temporarily or add an exception for 0AD. ||
|| Crash when starting a match || Try disable `Post-processing` in the game options, while leaving `Prefer GLSL` on. ||
|| No replay files are generated || Do you have any antivirus software running? Try disabling it temporarily or add an exception for 0AD. ||
|| Errors are displayed || Try to disable all mods not compatible with the new version. ||
|| Registering for the Game Lobby does not work || Try to disable `TLS` via `Settings` => `Options` => `Lobby`[[BR]][[Image(FAQ:disableTLS.jpg,500)]][[BR]]PS: There is a limit in the number of accounts you can submit per hour, try again later. ||
|| The multiplayer lobby is empty || You are probably using an older version of the game, see [https://play0ad.com/download/ play0ad.com/download] for the latest version. ||
|| How to play online? || Go to `Multiplayer` --> `Game Lobby` ||
|| I forgot my  `Game Lobby` password || Resetting is currently not possible via the GUI, you would need to create an account on the forum and contact [https://wildfiregames.com/forum/profile/21426-user1/ user1]. ||
|| How to play via LAN? || See this forum thread with detailed instructions - [https://wildfiregames.com/forum/topic/21614-multiplayer-on-lan/?do=findComment&comment=325645 Multiplayer on LAN (16/Jan/17)]. ||
|| My friend cannot join my game and I cannot join their game. || If you forward the port, everyone will be able to join you. If you use STUN when hosting, probably many but not everyone will be able to join you. If you can't join someone else's game, there's nothing you can do about it other than informing the host that he should port forward or host your own game. ||
|| What is port forwarding UDP 20595? || A port forward is a way of making a computer on your network accessible to computers on the internet, even though they are behind a router. It is commonly used in gaming, security camera setup, voice over ip, and downloading files. After you have forwarded a port you are said to have an open port. 0 A.D. uses the port 20595. ||
|| How to do port forwarding? || This can be adjusted in your router settings, try googling the manual of your router and follow the instructions from there.[[BR]][[Image(FAQ:router_port_forwarding.jpg,400)]] ||
|| Increasing the User Interface || Add `gui.scale = "1.2"` to your `user.cfg` file, you can increase this number if you like, this will likely become an option with A25.[[BR]][[Image(FAQ:user_cfg.jpg,400)]] ||
|| Where do I find my replays, save files and configuration files (e.g `user.cfg`)? || see [https://trac.wildfiregames.com/wiki/GameDataPaths wiki/GameDataPaths] ||
|| Game is lagging || Yes, it's a general issue of the game. See this forum thread with recommendation to avoid lag: [https://wildfiregames.com/forum/topic/27600-lag-in-0-ad-a-few-questions/ Lag in 0 AD - A Few Questions] (12/Feb/20). ||

== Gameplay ==
||= '''Question''' =||= '''Answer''' =||
|| How do you destroy a building instead of capturing it? || Hold `Ctrl` before `right-clicking` on the building you want to destroy. ||
|| How does capturing work? || The buildings have `capture points` for all players. If a player reaches 100% of the `capture points` for that building that player gains control over that building. `Capture points` can be gained by ordering units to capture that building or by that building standing inside a players area of influence (the player-coloured borders). ||
|| Where can I find all keyboard combinations for the game? || (1) Either in the game itself via the GUI `Hotkeys` button or[[BR]](2) see [https://trac.wildfiregames.com/wiki/HotKeys wiki/HotKeys] ||
|| How do I find idle units? || (1) There is a button right below the minimap[[BR]](2) You can also press `.` ||
|| How do you select all idle workers? || Press `Alt + .` ||
|| How do you select only military units? || Press `Alt` and `Left Drag` with your mouse a rectangle over your units. ||
|| Can you make groups of units? || Select a bunch of units and then press `Ctrl + 1`, you can make more multiple groups by using different numbers. ||
|| How does trade work? || Select a trader and send it from your market to any allied market. It will give you some free resources over time. ||
|| How is my "Game Lobby" rating calculated? || [NEEDS EXPLANATION, it uses ELO like chess, but more details would be nice] ||
|| How are the total, economy, military and exploration score calculated? || (1) Total = Sum of economy, military and exploration score[[BR]](2) Economy = Sum of all resources + trade income, divided by 10[[BR]](3) Military = Sum of enemyUnitsKilledValue, unitsCapturedValue, enemyBuildingsDestroyedValue and buildingsCapturedValue, divided by 10[[BR]](4) Exploration = percentMapExplored, multiplied with 10[[BR]][[Image(FAQ:score.jpg,500)]] ||

||= Question =||= '''Answer''' =||
|| How to keep up with the game? || For casual players there is no channel that summarizes progress.

We're working on the game in our spare time, so we don't know how much time we'll have to make the game. We've never developed a game before, so we don't know how long it will take to do one or the other. ||
|| Will you put the game on Steam? || We're going to look at putting the game on Steam to make it easier for people to find out about it, but not until we get to the beta stage at the earliest.
