## **Method**
## **Launch**
***• void Launch()***

After establishing the CloudGame object, call Launch() to connect to the server. There are two overloadings. One of the overloadings has no designated the numbers of seconds of timeout, and the other functions under the system's default value. If the connection fails to work within the time limit, OnCompletion will be triggered due to timeout.

***• void Launch(int timeout)***

| parameter | note |
|:------- |:---------------- |
| timeout | designate the number of seconds of timeout |

## **UnityLaunch**
***• void UnityLaunch()***

In the development environment of Unity3D, please call this function at the beginning of processing the program. In practice, if the function is not called, there may be unpredictable errors on some platforms such as Android phones.
This function only needs to be called once, but calling it several times will not lead to negative results. However, the first call must be executed before the new CloudGame().

***• void UnityLaunch(int timeoutSec)***

| parameter | note |
|:------- |:---------------- |
| timeoutSec | designate the number of seconds of timeout|

## **Dispose**
***• void Dispose()***

After ending the connection to the server, the CloudGame object cannot be used again. If there is a need for re-connection, another new CloudGame object have to be established, and then do the Launch().

## **GetUserGrade**
***• int GetUserGrade()***

After the player logs in successfully, this method sends back player's member status.

| status code | note |
|:------ |:------------------------------------------------------------------- |
| 0 | an account obtained by the system |
| 1 | A formal account registered by player or a formal account that upgrades from Level 0, which has not passed the email verification yet.|
| 2 | Formal account that passes the email verification. |
| 3 | A VIP player, who is not restricted by the game's CCU Max. |

## **SendOnClose**
***• void SendOnClose(string msg, uint poid)***

Pre-save message data to the server, so a player can send the message to other players when disconnected. This overloading can designate receiver's poid and send offline messages to particular online users, which is often the poid of DP in practice.

| parameter | note |
|:---- |:------------- |
| msg | Message data. |
| poid | Receiver's poid. |

***• void SendOnClose(string msg, CloudScene scene)***

Pre-save message data to the server, so a player can send the message to other players when disconnected. This overloading can designate specific scenes and send offline messages to users in this scene.

| parameter | note |
|:----- |:---------------- |
| scene | designate to send the offline messages to this scene|
| msg | message data |

## **PrivacySend**
***• void PrivacySend(string msg, uint poid)***

Send messages to selected players and designate receivers with poid (private scene id).

| parameter | note |
|:---- |:------------- |
| msg | Message data. |
| poid | Receiver's poid. |

## **StartDelayDetectionRadar**
***• void StartDelayDetectionRadar(int speed)***

Start the packet delay detection radar to detect the delay time of the packet-sending between the local and the game server.

| parameter | note |
|:----- |:------------ |
| speed | detect interval blocks |

Start the packet delay detection radar to detect the delay time of the packet-sending between the local and the game server.

|block | note |
|:---- |:------------------------------------------ |
| 0 | stops detecting |
| 1 | has the longest interval time, making it more suitable for games that require less instancy. |
| 5 | has the shortest interval time, making it more suitable for games that require more instancy. |

Supplementary Note :

Please depend the choice of levels on the games' characteristics. When using the high-speed level, the received information is the latest and the most accurate, but user's broadband will experience a more tremendous consumption. By contrast, the low-speed level consumes less broadband, but the obtained information may be detected earlier.
Before activating the CloudGame object, please activate the detection radar, which is when CloudGame.OnCompletion() is triggered and the status code is successful

## **GetDelayMillisecond**
***• int GetDelayMilliseconds()***

Obtain the delay time of the packet-sending between the current location and the game server, and the unit is millisecond. In order to use this information, activate the packet delay detection radar with StartDelayDetectionRadar() first.

| Key | Value |
|:------ |:-------- |
| userid | Player's account. |
| poid | Personal scene. |

Example: obj obtains the player’s data that are sent back.

C#

List<Hashtable> s = (List<Hashtable>)obj;
string userid;

{
	userid=(string)node["userid"];

| BX | The BX register data for setting BX has to be an integer. When one chooses to not set BX, send the BX register to null. |
| CX | The CX register data for setting CX has to be an integer. When one chooses to not set CX, send the CX register to null. |
| DX | The DX register data for setting DX has to be an integer. When one chooses to not set DX, send the DX register to null. |

Supplementary Note :
Register is a data system that is faster and more convenient in storing player's data than CloudItem.
Every player has his own four registers in the game, which is named AX, BX, CX, and DX. The four registers function as integers, and the developers can define their purposes. Aside from reading their values with `GetPlayerRegister()`, more importantly, when the game wants to ask the system to randomly select unspecified players with`CloudGame.GetRandomPlayer()`(such as when doing random teaming), it can designate the registers' conditions. In this way, only the players that meet the conditions will be chosen. To see further explanation on randomly selecting players, please go to

<mark>Please be aware that CX and DX can only be read by users themselves and super users. The players that CloudGame.GetRandomPlayer() randomly selects will only send back userid, nickname, AX, and BX.

The types of back-sendings:
`void cb(int code, object token)`

The following are the codes' status codes and their notes.
