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);

BuildReport report = BuildReport.GetLatestReport(); if (report != null) { var sb = new StringBuilder(); sb.AppendLine("Build result : " + report.summary.result); sb.AppendLine("Build size : " + report.summary.totalSize + " bytes"); sb.AppendLine("Build time : " + report.summary.totalTime); sb.AppendLine("Error summary : " + report.SummarizeErrors()); sb.Append(LogBuildReportSteps(report)); sb.AppendLine(LogBuildMessages(report)); Debug.Log(sb.ToString()); } else { // Certain errors like invalid input can fail the build immediately, with no BuildReport written Debug.Log("AssetBundle build failed"); } }

public static string LogBuildReportSteps(BuildReport buildReport) { var sb = new StringBuilder();

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(); }

string messages = sb.ToString(); if (messages.Length > 0) return "Messages logged during Build:\n" + messages; else return ""; } }

strippingInfoThe StrippingInfo object for the build.
summaryA BuildSummary containing overall statistics and data about the build process.

Public Methods

GetFilesReturns an array of all the files output by the build process.
SummarizeErrorsReturns a string summarizing any errors that occurred during the build

Static Methods

GetLatestReportReturn the build report generated by the most recent Player or AssetBundle build

Inherited Members

Properties

hideFlagsShould the object be hidden, saved with the Scene or modifiable by the user?
nameThe name of the object.

Public Methods

GetInstanceIDGets the instance ID of the object.
ToStringReturns the name of the object.

Static Methods

DestroyRemoves a GameObject, component or asset.
DestroyImmediateDestroys the object obj immediately. You are strongly recommended to use Destroy instead.
DontDestroyOnLoadDo not destroy the target Object when loading a new Scene.
FindAnyObjectByTypeRetrieves any active loaded object of Type type.
FindFirstObjectByTypeRetrieves the first active loaded object of Type type.
FindObjectsByTypeRetrieves a list of all loaded objects of Type type.
InstantiateClones the object original and returns the clone.
InstantiateAsyncCaptures a snapshot of the original object (that must be related to some GameObject) and returns the AsyncInstantiateOperation.

Operators

boolDoes the object exist?
operator !=Compares if two objects refer to a different object.
operator ==Compares two object references to see if they refer to the same object.
