# Objective
Simplify Bevy-provided functions that return a condition-satisfying
closure instead of just being the condition.
## Solution
Become the condition.
## Testing
I did not test. Game jamming. Hopefully CI passes.
---
## Migration Guide
Some run conditions have been simplified.
```rust
// Before:
app.add_systems(Update, (
system_0.run_if(run_once()),
system_1.run_if(resource_changed_or_removed::<T>()),
system_2.run_if(resource_removed::<T>()),
system_3.run_if(on_event::<T>()),
system_4.run_if(any_component_removed::<T>()),
));
// After:
app.add_systems(Update, (
system_0.run_if(run_once),
system_1.run_if(resource_changed_or_removed::<T>),
system_2.run_if(resource_removed::<T>),
system_3.run_if(on_event::<T>),
system_4.run_if(any_component_removed::<T>),
));
```
