CreateScript - Amazon GameLift


Creates a new script record for your Realtime Servers script. Realtime scripts are JavaScript that provide configuration settings and optional custom game logic for your game. The script is deployed when you create a Realtime Servers fleet to host your game sessions. Script logic is executed during an active game session.

To create a new script record, specify a script name and provide the script file(s). The script files and all dependencies must be zipped into a single file. You can pull the zip file from either of these locations:

  • A locally available directory. Use the ZipFile parameter for this option.

  • An Amazon Simple Storage Service (Amazon S3) bucket under your AWS account. Use the StorageLocation parameter for this option. You'll need to have an Identity Access Management (IAM) role that allows the Amazon GameLift service to access your S3 bucket.

If the call is successful, a new script record is created with a unique script ID. If the script file is provided as a local file, the file is uploaded to an Amazon GameLift-owned S3 bucket and the script record's storage location reflects this location. If the script file is provided as an S3 bucket, Amazon GameLift accesses the file at this storage location as needed for deployment.

Request Syntax

{ "Name": "string", "StorageLocation": { "Bucket": "string", "Key": "string", "ObjectVersion": "string", "RoleArn": "string" }, "Tags": [ { "Key": "string", "Value": "string" } ], "Version": "string", "ZipFile": blob }

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.


In the following list, the required parameters are described first.


A descriptive label that is associated with a script. Script names don't need to be unique. You can use UpdateScript to change this value later.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 1024.

Required: No


The location of the Amazon S3 bucket where a zipped file containing your Realtime scripts is stored. The storage location must specify the Amazon S3 bucket name, the zip file name (the "key"), and a role ARN that allows Amazon GameLift to access the Amazon S3 storage location. The S3 bucket must be in the same Region where you want to create a new script. By default, Amazon GameLift uploads the latest version of the zip file; if you have S3 object versioning turned on, you can use the ObjectVersion parameter to specify an earlier version.

Type: S3Location object

Required: No


A list of labels to assign to the new script resource. Tags are developer-defined key-value pairs. Tagging AWS resources are useful for resource management, access management and cost allocation. For more information, see Tagging AWS Resources in the AWS General Reference. Once the resource is created, you can use TagResource, UntagResource, and ListTagsForResource to add, remove, and view tags. The maximum tag limit may be lower than stated. See the AWS General Reference for actual tagging limits.

Type: Array of Tag objects

Array Members: Minimum number of 0 items. Maximum number of 200 items.

Required: No


Version information associated with a build or script. Version strings don't need to be unique. You can use UpdateScript to change this value later.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 1024.

Required: No


A data object containing your Realtime scripts and dependencies as a zip file. The zip file can have one or multiple files. Maximum size of a zip file is 5 MB.

When using the AWS CLI tool to create a script, this parameter is set to the zip file name. It must be prepended with the string "fileb://" to indicate that the file data is a binary object. For example: --zip-file fileb://

Type: Base64-encoded binary data object

Length Constraints: Maximum length of 5000000.

Required: No

Response Syntax

{ "Script": { "CreationTime": number, "Name": "string", "ScriptArn": "string", "ScriptId": "string", "SizeOnDisk": number, "StorageLocation": { "Bucket": "string", "Key": "string", "ObjectVersion": "string", "RoleArn": "string" }, "Version": "string" } }

Response Elements

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.


The newly created script record with a unique script ID and ARN. The new script's storage location reflects an Amazon S3 location: (1) If the script was uploaded from an S3 bucket under your account, the storage location reflects the information that was provided in the CreateScript request; (2) If the script file was uploaded from a local zip file, the storage location reflects an S3 location controls by the Amazon GameLift service.

Type: Script object
