REST API
In Q2 2015 you can connect to the Tygron Engine via a REST API.
More info about rest can be found here
Specs
- JSON format.
- SSL encrypted with same credentials for normal Engine login.
Authentication
To use the API, you must have a valid Tygron account on the server. If multiple Tygron servers are in use, you must have these credentials on the server you are trying to access. When accessing the API via the browser, you will be prompted for these credentials. The Tygron Engine uses Basic access authentication.
Authenticating against sessions
Although access to the API generally requires authentication with account credentials, sessions on the server require tokens to access. Your application must provide these in the header of the http request when attempting to access a server. An example:
serverToken: 872ad98e-9bfe-4ae1-a498-0e8ca74469ce clientToken: 4b6af59c-0eda-49c3-ac73-56c8d2ce40f0
The server token serves as an authentication for a specific sessions. Each session has a different server token. The client token serves as a unique identifier to tell you or your application apart from other clients connected to the same session. For convenience in the browser, you can also append a query parameter "token" to your URL, to provide the proper serverToken. For example:
?token=872ad98e-9bfe-4ae1-a498-0e8ca74469ce&clientToken=4b6af59c-0eda-49c3-ac73-56c8d2ce40f0
Note that the serverToken in this case is simply called token.
The api for the Tygron Engine can be reached by appending the URL for the Tygron Engine with "/api/". For example: https://www.tygronengine.com/api/
To see the full range of options available through the API, it is recommended to use your browser to access the API. You will be prompted to log in with your Tygron Engine username and password.
By default, all options and information available through the API is presented in human-readable webpages. Most information in the Tygron Engine can easily be reached by following the links on these pages.
Parts of the API can be reached directly. There is also a listing of all "slots" on the server. In each slot a session can be run. When attempting to access a session, you must be sure to provide an appropriate server token.
Sessions
The Tygron Engine acts as a central server. On it, information regarding domains, users and projects is stored. To interact with a project (whether it's creating, editing or playing) the project must be started in the appropriate fashion on the server.
To start a session on the server, you must authenticate with appropriate credentials. You can then instruct the server to start your project in a variety of modes. After the session has started, you can request information regarding the session, including a server token with which you can interact with the session, and a client token which will serve as your unique identification to the session.
A session is automatically closed when no client interacts with it for some time. Interaction can be as simple as requesting information from the session. However, your application is recognized as an interacting client if it does so providing its client token.
Activating and closing sessions
There are multiple events involved in having your application neatly interact with a session on the server.
- IOServicesEventType.START_NEW_SESSION: This event starts a project on the server. No interaction takes place yet. If the project is already opened in Editor mode, it cannot be opened again, either in an Editor or as a playable game, until the session is closed. If the project has been opened in Single Player or Multiplayer mode, the project cannot be edited until all the playable sessions have closed.
- IOServicesEventType.GET_JOINABLE_SESSIONS: This event lists all currently running sessions which you are able to join.
- IOServicesEventType.JOIN_SESSION: This event provides you with tokens you can use to join the project. The serverToken is necessary to interact with the specific project. The clientToken identifies your program to the server, allowing it to recognize there is a client interacting with the project. If no clients interact with a project for too long, the sessions closes automatically.
- IOServicesEventType.CLOSE_SESSION: This event lets the server know your application has left the session. This means any stakeholder you have selected is freed up for another client, and the server no longer considers your client part of the session. When all clients have left a session, the session can be closed immediately, or times out after a set period.
- IOServicesEventType.KILL_SESSION: This event terminates a session immediately.
Return codes
200: Success: This means the request was accepted.
406: Not Acceptable. This is returned when a request is made to an URL, requesting a format which cannot be returned. For example, the base URL of the api (api/) can be viewed in the browser, because it is returned in HTML, but will cause this statuscode when requested in JSON format.
