◆ emplace() [1/2]

template<typename Self >

template<typename T , typename ... Args, typename A = actual_type_t<T>>

Self & flecs::entity_builder< Self >::emplace ( Args &&... args )

inline

Emplace component.

Emplace constructs a component in the storage, which prevents calling the destructor on the value passed into the function.

Emplace attempts the following signatures to construct the component: T{Args...} T{flecs::entity, Args...}

If the second signature matches, emplace will pass in the current entity as argument to the constructor, which is useful if the component needs to be aware of the entity to which it has been added.

Emplace may only be called for components that have not yet been added to the entity.

Template Parameters

T	the component to emplace

Parameters

args	The arguments to pass to the constructor of T

The operation will invoke modified for each component after the callback has been invoked.

Parameters

func	The callback to invoke.
