How to create non-auto view type?

[SC5Shout]

Is there any way I can have this:

entt::view<position, const velocity> view = registry.view<position, const velocity>();

instead of using auto view = ...?

I see a similar example here https://github.com/skypjack/entt/wiki/Entity-Component-System#types-const-non-const-and-all-in-between. But I get these errors:

I need this to take a view inside a function parameter like this:

void Update(entt::view<position, const velocity> view);

Sure thing, it's:

entt::view<entt::get_t<position, const velocity>> view = registry.view<position, const velocity>();

See here for example. Also, thanks for pointing out that the documentation is wrong on this. Sorry for that. 👍

ough, this is ugly 😬. I'll do this tough

template<typename ... Comp>
using View = entt::view<entt::get_t<Comp...>>;

Thanks!
