SimSpace Weaver API references

SimSpace Weaver has 2 different sets of application programming interfaces (APIs):

  • Service APIs – These APIs control the service and service resources, such as your simulations, clocks, and apps. They are part of the main AWS software development kit (SDK) and you can use the AWS Command Line Interface (CLI) to call them. You can also use the convenience script in the tools folder for your project and platform (for example, project-folder\tools\windows\weaver-project-name-cli.bat) to call these APIs. For more information about the servcie APIs, see the SimSpace Weaver API reference.

  • App SDK APIs – These APIs control the data within your simulation. You use them in your app code to do things like read and write entity field data, work with subscriptions, and monitor events in the simulation. For more information, see the SimSpace Weaver app SDK documentation in your unzipped app SDK folder: sdk-folder\SimSpaceWeaverAppSdk-1.16.0\documentation

    Note

    sdk-folder is the folder where you unzipped the SimSpaceWeaverAppSdkDistributable package. If sdk-folder\SimSpaceWeaverAppSdk-1.16.0 doesn't exist, make sure that you have version 1.16.0 of the SimSpace Weaver app SDK. The SimSpaceWeaverAppSdkDistributable doesn’t contain the entire SimSpace Weaver app SDK. The first time you use the SimSpace Weaver app SDK scripts to create a project, the scripts create the SimSpaceWeaverAppSdk-1.16.0 folder inside your sdk-folder and download the rest of the SimSpace Weaver app SDK into it.
