Bevy Stat Bars

Simple library for drawing floating stat bars.

About

• Successor to bevy_simple_stat_bars.
• The style options are very limited, only colors and borders.
• There is some very basic automatic color interpolation support (So a health bar changes to red when health low, for example).
• Uses the builtin Bevy sprite renderer for drawing.
• 0.2 requires that StarBar/StarBars entities also have the VisibilityBundle components, otherwise they won't be drawn.
• version 0.2+ supports Bevy 0.8, 0.1 supports Bevy 0.7

Usage

In your Cargo.toml [dependencies] section, add the line:

toml bevy_stat_bars = "0.2" This is a minimal app that should draw a 75% full stat bar in the middle of the window: ```rust use bevy::prelude::; use bevy_stat_bars::;

fn main() { App::new() .addplugins(DefaultPlugins) .addplugin(StatBarsPlugin) .addstartupsystem(|mut commands: Commands| { commands .spawnbundle(Camera2dBundle::default()) .commands() .spawnbundle(StatBarBundle::new(StatBar { value: 0.75, size: Vec2::new(200., 20.), ..Default::default() })); })
.run(); } ```

There are some complete examples you can run with the commands: cargo run --example basic cargo run --example interactive cargo run --example minimal cargo run --example interpolation

Notes

• 0.2 update is just a bunch of hacks to get the crate to work with Bevy 0.8. The GlobalTransform stuff especially I don't know what I'm doing there and might be a performance bottleneck if you are drawing 100,000 stat bars every update.

• The math is very hacky and I think there is a problem with the rotations where they don't quite compose in the natural way you'd expect.

  It's not much of a problem though. Will be fixed next release.
