template<typename T>
static System cubos::core::ecs::System<T>::make(World& world, auto function, const std::vector<SystemOptions>& options = {})

Creates a new system for the given world with the given function and options.

Parameters
world World the system will access.
function System function, which should return T.
options Options for the system arguments.

The first option is applied to the first argument which requests it, and the same for subsequent options. If there are more options than arguments which request them, aborts. Otherwise, if there are more arguments requesting options than supplied options, the remaining arguments are assigned default-value options.

template<typename T>
cubos::core::ecs::System<T>::System(System&& system) defaulted noexcept

Parameters
system Other system.

template<typename T>
T cubos::core::ecs::System<T>::run(const SystemContext& ctx)

Runs the system.

Parameters
ctx Context.
Returns Return value.

template<typename T>
const SystemAccess& cubos::core::ecs::System<T>::access() const

Gets a reference to the access patterns of the system.
