Description

The BuildReport API gives you information about the Unity build process.

A BuildReport object is returned by BuildPipeline.BuildPlayer and can be used to discover information about the files output, the build steps taken, and other platform-specific information such as native code stripping.

For AssetBundle builds the BuildReport is available by calling GetLatestReport immediately after calling BuildPipeline.BuildAssetBundles.

public class BuildReportExample { [MenuItem("Example/Build AssetBundle")] static public void BuildBundles() { string buildOutputDirectory = "BuildOutput"; if (!Directory.Exists(buildOutputDirectory)) Directory.CreateDirectory(buildOutputDirectory);

var bundleDefinitions = new AssetBundleBuild[] { new AssetBundleBuild() { assetBundleName = "MyBundle", assetNames = new string[] { "Assets/Scenes/SampleScene.unity" } } };

BuildPipeline.BuildAssetBundles( buildOutputDirectory, bundleDefinitions, BuildAssetBundleOptions.ForceRebuildAssetBundle, EditorUserBuildSettings.activeBuildTarget);

sb.AppendLine($"Build steps: {buildReport.steps.Length}"); int maxWidth = buildReport.steps.Max(s => s.name.Length + s.depth) + 3; foreach (var step in buildReport.steps) { string rawStepOutput = new string('-', step.depth + 1) + ' ' + step.name; sb.AppendLine($"{rawStepOutput.PadRight(maxWidth)}: {step.duration:g}"); } return sb.ToString(); }
