RCCService

RCCService is the server Roblox has used since 2008 to manage game servers and rendering thumbnails. It stands for Roblox Cloud Compute Service, and uses SOAP over HTTP (typically 127.0.0.1:64989). (Credits: BrentDamage, ORC Guide, Finobe.lol, and lrre.wiki.)

SOAP Methods

RCCService exposes a WSDL interface with the following methods. Types suffixed with Ex return strongly-typed ArrayOfLuaValue instead of raw arrays.

Method	Parameters	Returns
HelloWorld	(none)	string
GetVersion	(none)	string
GetStatus	(none)	Status (version string, environmentCount int)
OpenJob / OpenJobEx	Job, ScriptExecution (optional)	LuaValue[]
BatchJob / BatchJobEx	Job, ScriptExecution	LuaValue[]
Execute / ExecuteEx	jobID (string), ScriptExecution	LuaValue[]
RenewLease	jobID (string), expirationInSeconds (double)	double
CloseJob	jobID (string)	void
GetExpiration	jobID (string)	double
GetAllJobs / GetAllJobsEx	(none)	Job[]
CloseExpiredJobs	(none)	int
CloseAllJobs	(none)	int
Diag / DiagEx	type (int), jobID (string, optional)	LuaValue[]

Data Types

• Job — {id: string, expirationInSeconds: double, category: int, cores: double}
• ScriptExecution — {name: string, script: string, arguments: LuaValue[]}
• LuaValue — {type: LuaType, value: string, table: LuaValue[]}
• LuaType — enum: LUA_TNIL, LUA_TBOOLEAN, LUA_TNUMBER, LUA_TSTRING, LUA_TTABLE

PHP Usage

$rcc = new Roblox\Grid\Rcc\RCCServiceSoap('127.0.0.1', 64989); $rcc->HelloWorld(); $rcc->GetVersion(); $status = $rcc->GetStatus(); $jobs = $rcc->GetAllJobs();

$job = new Roblox\Grid\Rcc\Job('job-id'); $script = new Roblox\Grid\Rcc\ScriptExecution('script-name', 'print("hello")'); $result = $rcc->BatchJob($job, $script); </syntaxhighlight>
