```

### Parameters

**** (\[Entity]\(/engine/7000.0/script-reference/unity/entities/entity)): The entity.**** (\[float3]\(/engine/7000.0/script-reference/unity/mathematics/float3)): The position relative to the parent, or to the world if the entity has no parent.**** (\[quaternion]\(/engine/7000.0/script-reference/unity/mathematics/quaternion)): The rotation relative to the parent, or to the world if the entity has no parent.**** (\[float3]\(/engine/7000.0/script-reference/unity/mathematics/float3)): The scale relative to the parent, or to the world if the entity has no parent.

### Returns
