Entities with an IndependentTransform have a position relative to their parent, but aren't part of the Bevy Transform hierarchy.
With Transform :
With IndependentTransform:
Supports Bevy 0.8
Add the dependency to your Cargo.toml
toml
bevy_independent_transform = "0.1"
and the plugin to your App
rust
fn main() {
App::new()
.add_plugins(DefaultPlugins)
.add_plugin(IndependentTransformPlugin)
// .. rest of App
run()
}
IndependentTransform is a newtype wrapping Transform.
Like Transform, an entity with a IndependentTransform should also have a GlobalTransform.
You can insert an IndependentTransform component directly, or spawn one of the bundles included with this crate:
* IndependentSpriteBundle
* IndependentSpriteSheetBundle
* IndependentText2dBundle
* IndependentTransformBundle
If an entity has both IndependentTransform and Transform components, the IndependentTransform component will be ignored.
cargo run --example text
cargo run --example sprites
For an alternative that respects the Bevy transform hierarchy, see my other crate at
https://github.com/ickshonpe/bevyfixedsprites
The approach here seems better for text and game icons, and bevyfixedsprites is probably better for sprites representing game characters and objects.
I'm not sure how to combine both methods. Maybe it's not possible without introducing a lot of complexity and extra components, and/or replacing Bevy's transform_propagate_system system
entirely. Haven't really thought about it much though.
