Of course, you'll need to update the name later before your game is announced and releases its Coming Soon store page. [*]Release State Override keys are limited to 2,500 per app. If you need more than 2,500 keys for a confidential playtest, then the probability of a leak is increasing to the point where you're likely "announcing" your product anyway. …

The compressed data provided is in an arbitrary format and is not meant to be played directly. This should be called once per frame, and at worst no more than four times a second to keep the microphone input delay as low as possible. Calling this any less may result in gaps in the returned stream. …

It's best to call this frequently, as the more time between calls, the more latency between receiving events or results from the Steamworks API. Most games call this once per render-frame, it's highly recommended that you call this at least once a second. All registered listener functions will be invoked during this call, in the thread context where [code-inline]SteamAPI_RunCallbacks[/code-inline] was called from. …

[section]Step 3 - The Steam Input API[/section] Make sure you have the latest version of the Steamworks API - Grab it from the [url=https://partner.steamgames.com/documentation/getting_started]Getting Started With SteamWorks[/url] page. Steam Input provides per-app mappings for controllers to decide which mapping to run and Steam will track the foreground window. This can make it trickier to debug the controller while you're working on it, because the controller will change its configuration when you hit a breakpoint in your debugger. …

Used for perf debugging so you can understand how many IPC calls your game makes per frame. Each IPC call is at minimum a thread context switch if not a process switch so you want to be diligent and possibly rate control how often you do them. …

A Quaternion Identity (x:0, y:0, z:0, w:1) will be sent in the first few packets while the controller's IMU is still waking up; some controllers have a short "warmup" period before these values should be used. After the first time GetMotionData is called per controller handle, the IMU will be active until your app is closed. The exception is the Sony DualShock, which will stay on until the controller has been turned off. …

If you are porting existing stream-oriented code to the semantics of reliable messages, your code should work the same, since reliable message semantics are more strict than stream semantics. The only caveat is related to performance: there is per-message overhead to retain the message sizes, and so if your code sends many small chunks of data, performance will suffer. Any code based on stream sockets that does not write excessively small chunks will work without any changes. …

It's best to call this at >10Hz, the more time between calls, the more potential latency between receiving events or results from the Steamworks API. Most games call this once per render-frame. All registered listener functions will be invoked during this call, in the callers thread context. SteamAPI_RunCallbacks is safe to call from multiple threads simultaneously, but if you choose to do this, callback code could be executed on any thread. …
