bevystatbars

Version 0.3

New stuff

• Completely rewritten. New design and API. Should (hopefully) be easier to use.
• Works nicely with bevy_inspector_egui now.
• Removed the arbitrary orientation stuff temporarily, just has reversible horizontal and vertical bars.
• Statbars can track resources as well as components.

• No plugin, need to register types tracked by Statbars before you can use them though.

  

How to use

Add the dependency to your Cargo.toml file with

toml [dependencies.bevy_stat_bars] version = "0.3"

Then register any components you want to observe with a Statbar with your Bevy App:

rust App::new() .add_plugins(DefaultPlugins) .add_statbar_bar_component_observer::<HitPoints>() // ..etc, rest of app .run();

You also need to implement the StatbarObservable trait on those components:

rust impl StatbarObservable for HitPoints { fn get_statbar_value(&self) -> f32 { self.value / self.max } }

And now you can add a Statbar::<HitPoints> component to an entity to visualize its HitPoints component

rust commands.entity(enemy_id) .insert_bundle(( Statbar::<HitPoints> { empty_color: Color::NAVY, length: 10., thickness: 2., displacement: 8. * Vec2::Y, ..Default::default() }, StatbarBorder::<HitPoints>::all(Color::WHITE, 1.), ));

#

Examples

There are five examples you can look at that cover most of the features and use cases, run them with cargo run --example minimal_standalone cargo run --example basic_interactive cargo run --example observe_resource cargo run --example demo cargo run --example stress --release The demo example is the probably the most useful to look at.

#

Notes

• Supports Bevy 0.8
• Still uses sprites for rendering which isn't ideal but performance seems fine. You can run the stress example to see what its like under a heavy load. I get about 100fps on my rx580.
