unreal.EditorValidatorSubsystem

class unreal.EditorValidatorSubsystem(outer: Object | None = None, name: Name | str = 'None')

Bases: EditorSubsystem

UEditorValidatorSubsystem manages all the asset validation in the engine. The first validation handled is UObject::IsDataValid and its overridden functions. Those validations require custom classes and are most suited to project-specific classes. The next validation set is of all registered UEditorValidationBases. These validators have a function to determine if they can validate a given asset, and if they are currently enabled. They are good candidates for validating engine classes or very specific project logic.

add_validator(validator) → None

  • Adds a validator to the list, making sure it is a unique instance

Return type:

tuple

is_object_valid(object, validation_usecase) -> (DataValidationResult, validation_errors=Array[Text], validation_warnings=Array[Text])
