Use Visual Scripting with Unity Cloud Build
At build time, Unity removes any code that isn't used by a project to reduce build size. This can cause problems with Visual Scripting because Unity can remove code that's necessary for Script Graphs to run in a project.
For versions 1.7.x, Visual Scripting generates an AotStubs.cs file, which stores the Unity APIs that graphs use. With the AotStubs.cs file, Unity doesn't remove any Unity APIs used in a graph from a build. You can generate this file when you create a build of a project.
Builds through Unity Cloud Build can fail because Cloud Build prevents domain reload between the prebuild and build phases of the project. Without a domain reload, the build doesn't include the generated AotStubs.cs file. For more information about domain reload, see Domain Reloading in the Unity User Manual.
To build a Visual Scripting project with Cloud Build, do the following:
-
Build the project locally for your desired platform.
For more information on how to build a project, see the relevant section for each platform in Platform development in the User Manual. -
After the build, do one of the following:
- Open the project files in the system file explorer.
- Open the Project window in the Unity Editor.
-
In the project files, go to Assets > Unity.VisualScripting.Generated > VisualScripting.Core.
-
Locate the
AotStubs.csfile. -
Add the
AotStubs.csfile to your source control system.
Your Cloud Build settings might automatically trigger a new build of the project after you commit the AotStubs.cs file. For more information about version control systems and Cloud Build, see Unity Cloud Build in the User Manual.
