After you activate an action such as "assign_group" or "add_remove_group", the game's programming will wait until an action such as "group_0" or "group_3" is pressed. "assign_group" + "group_2" means, "assign the current selection to group 2," whereas "select_group" + "group_5" means, "select everything currently assigned to group 5.…

Additionally, the Unit commands have the special action "queue." When an order action is received, if the game detects that the "queue" action is also currently being fired, it will not immediately execute the original order, but instead stick it on queue for that unit. …

Here you can stay up to date with popular café titles, see what's being played in arcades around the world and access available special offers. In order to view and purchase the commercial game licenses, you must be logged in with a Steam account that has previously signed the PC Café Agreement. …

Site license accounts will be able to purchase commercial packages multiple times or in quantity so the 2 weeks/2 hours clock starts ticking at the first purchase event. For example, if they purchased L4D and then 3 weeks later purchased another copy of L4D, a refund request would be denied because the first copy is more than 2 weeks old. If they instead purchased their second copy only 1 week after the first copy, both purchases could be refunded provided there was less than 2 combined hours of playtime on the licenses.

[subsection]Store Page Video Tutorial[/subsection] This Steamworks Tutorial details the process of creating and viewing your store page in Steam. https://www.youtube.com/watch?v=lU1SFAa3QqM [section]Updated Features for your store page[/section] [callout]Note: These are new features that have been added since the above video was released.…

" Be mindful that publishing a store page will move ALL store page data and assets (including screenshots, trailers and library assets) to Steam's public servers. There, they can potentially be scrapped or datamined by 3rd party websites and shared on social media. This is true even if your app is in an unreleased or hidden state, so be careful not to inadvertently share an unannounced game or secret DLC project with the public this way! …

[/list] [section]Frequently Asked Questions[/section] [h4]Q. Does my game have to be released in order to use Curator Connect?[/h4] [b]A.[/b] Your game needs to have at least a 'coming soon' page publicly visible before you can send copies of your game to Steam Curators. …

The Web API method calls must originate from a hosted server that is separated from the game client – the publisher key must not be shipped with any game client code. [section=Authentication]Authentication and 3rd Party Accounts[/section] In order to call the Game Notifications APIs, you must first establish the identity of the Steam user logged into your game. …

It is important that you do not trust user identity in messages sent directly from the game client to your game server, as these messages can be tampered with. For games that use 3rd party accounts, use the instructions provided above but cache the user’s Steam ID in your system. [section=API]Game Notifications API[/section] [subsection=TechOverview]Technical Overview[/subsection] The Game Notifications API is written and exposed through Web APIs and require 4 parameters passed in each method: [list] [*] appid (the application id for your game) [*] format (the format of the result. …

([apitype]steamnetworkingtypes::SteamNetworkingMessage_t[/apitype]::m_nConnUserData might also be useful.) Delivery order of messages among different connections will usually match the order that the last packet was received which completed the message. …

Usually you will call this function once, near the start of the connection, perhaps after exchanging a few messages. [*] To assign all lanes the same priority, you may use pLanePriorities=NULL. [*] If you wish all lanes with the same priority to share bandwidth equally (or if no two lanes have the same priority value, and thus priority values are irrelevant), you may use pLaneWeights=NULL [*] Priorities and weights determine the order that messages are SENT on the wire. There are NO GUARANTEES on the order that messages are RECEIVED! Due to packet loss, out-of-order delivery, and subtle details of packet serialization, messages might still be received slightly out-of-order! …

[section=examples]Examples[/section] [subsection=account_linking]Linking third-party accounts to Steam accounts[/subsection] Third-party accounts can be linked to Steam accounts by associating a user's SteamID with the 3rd party account. A user's SteamID can be securely retrieved either in-game or through a web browser and once the initial association has occurred, you can safely allow access to the 3rd party account by merely verifying a user's SteamID. This eliminates the need for Steam users to do any sort of secondary login to 3rd party account systems. Additionally, if new 3rd party accounts can be automatically created and linked when a new SteamID is encountered, the Steam user will never have to be aware that a secondary authentication is taking place at all. …
