PackageImportWizard

Internal proxy for Unity's UnityEditor.PackageImportWizard. Drives the multi-step import wizard UI with step navigation, import execution, and cancellation.

Definition

Namespace: Paragon.Editor.ThirdPartyPackageImporter.Internals Assembly: Paragon.Editor.dll

[InternalProxy("UnityEditor.PackageImportWizard", "UnityEditor.CoreModule")]
internal class PackageImportWizard : InternalProxy<PackageImportWizard>

Inheritance: InternalProxy<PackageImportWizard> → PackageImportWizard

Remarks

PackageImportWizard controls the wizard flow within Unity's package import dialog. It is accessed as a ScriptableSingleton<> instance by PackageImportWindow and PackageExportWindow.

All method calls are wrapped in try/catch (ExitGUIException) blocks because Unity's internal wizard methods may throw ExitGUIException as part of normal GUI flow control (e.g., when changing layout during repaint). These exceptions are silently caught and ignored.

Properties

public bool IsMultiStepWizard { get; }

Whether the current import uses a multi-step wizard (e.g., packages with project settings).

IsProjectSettingStep

public bool IsProjectSettingStep { get; }

Whether the wizard is currently on the project settings step.

Common Pitfalls

ExitGUIException is expected All wizard methods catch and suppress ExitGUIException. This is normal Unity GUI behavior — do not remove these try/catch blocks.

Pass PackageImport.packageItems The importPackageItems parameter must be the raw object from PackageImport.packageItems, not a processed array. The wizard expects Unity's internal item format.
