Attribute

DisableAutoCreationAttribute

Namespace: Unity.Entities

Syntax

[AttributeUsage(AttributeTargets.Assembly | AttributeTargets.Class | AttributeTargets.Struct, Inherited = false)]
public sealed class DisableAutoCreationAttribute : Attribute, _Attribute

Remarks

By default, all systems (classes derived from ComponentSystemBase or ISystem) are automatically discovered, instantiated, and added to the default World when that World is created.

Add this attribute to a system class that you do not want created automatically. Note that the attribute is not inherited by any subclasses.

using Unity.Entities;

[DisableAutoCreation]
public partial class CustomSystem : SystemBase
{ // Implementation... }

You can also apply this attribute to an entire assembly to prevent any system class in that assembly from being created automatically. This is useful for test assemblies containing many systems that expect to be tested in isolation.

To declare an assembly attribute, place it in any C# file compiled into the assembly, outside the namespace declaration:

using Unity.Entities;

[assembly: DisableAutoCreation]
namespace Tests{}
