Description

Composite initializer that executes multiple SpawnInitializers in sequence.

InitializerList allows combining multiple initialization behaviors into a single initializer. Each initializer in the list is executed in order during the spawn process.

**Usage:** ```cpp auto initializer = std::make_unique<InitializerList<2>>( std::make_unique<DirectionInitializer>(vec3f{1, 0, 0}), std::make_unique<VelocityInitializer>(100.0f) ); ```

Template Parameters

N	The number of initializers in the list. Must match the number of arguments passed to the constructor.

Public Constructors

InitializerList()

template <typename... Args>

helios::engine::runtime::spawn::behavior::initializers::InitializerList< N >::InitializerList (std::unique_ptr< Args > &&... args)

inline explicit

Constructs an InitializerList from variadic initializer arguments.

Template Parameters

Args	Types of the initializer unique_ptrs.

Parameters

args	Unique pointers to SpawnInitializer instances. The number of arguments must match the template parameter N.
