# Objective
Sometimes you want to create a plugin with a custom run condition. In a
function, you take the `Condition` trait and then make a
`BoxedCondition` from it to store it. And then you want to add that
condition to a system, but you can't, because there is only the `run_if`
function available which takes `impl Condition<M>` instead of
`BoxedCondition`. So you have to create a wrapper type for the
`BoxedCondition` and implement the `System` and `ReadOnlySystem` traits
for the wrapper (Like it's done in the picture below). It's very
inconvenient and boilerplate. But there is an easy solution for that:
make the `run_if_inner` system that takes a `BoxedCondition` public.
Also, it makes sense to make `in_set_inner` function public as well with
the same motivation.
A chunk of the source code of the `bevy-inspector-egui` crate.
## Solution
Make `run_if_inner` function public.
Rename `run_if_inner` to `run_if_dyn`.
Make `in_set_inner` function public.
Rename `in_set_inner` to `in_set_dyn`.
## Changelog
Changed visibility of `run_if_inner` from `pub(crate)` to `pub`.
Renamed `run_if_inner` to `run_if_dyn`.
Changed visibility of `in_set_inner` from `pub(crate)` to `pub`.
Renamed `in_set_inner` to `in_set_dyn`.
