Determine debug or release build in a PostProcessScene callback.

Unity Engine

Hi, I was going through this code: DOTSSample/Assets/Scripts/Build/Editor/ScenePostProcessor.cs at master · Unity-Technologies/DOTSSample · GitHub

And from what I can tell, the isDevelopmentBuild boolean is never modified anywhere, I even tried to look it up from an IDE.

And so I wanted to ask if there is some way to determine which type of a build it is (release, or debug) from a PostProcessScene callback.

Solutions I have considered:

  • Use IProcessSceneWithReport - The same problem, don’t know how to determine the build type.
  • Use DEVELOPMENT_BUILD define - Only true in a player, will be false in the editor.
  • Use DEBUG - will always be true inside the editor.
  • Use a manual define - not enough automation for my programmer tastes, but is the fallback plan if I can’t find any solutions.

Old question, but for those still facing this problem you can use IProcessSceneWithReport and use report.summary.options.HasFlag(BuildOptions.Development) to determine if it’s a development build. As said in Unity docs, IProcessSceneWithReport.OnProcessScene will also run when playing a scene in the Editor, so you need to check BuildPipeline.isBuildingPlayer if you want to run code only when building.

Here’s a quick example:

public class SomeSceneProcessor : IProcessSceneWithReport
{
    public int callbackOrder => 0;

    public void OnProcessScene(Scene scene, BuildReport report)
    {
        // Make sure it runs only for builds and not
        // when playing the scene in the Editor.
        if (!BuildPipeline.isBuildingPlayer)
        {
            return;
        }

        if (report.summary.options.HasFlag(BuildOptions.Development))
        {
            // Code for development builds.
        }
        else
        {
            // Code for release builds.
        }
    }
}
