Use 2d sprites in a 3d bevy scene.
This is a pretty common setup in other engines (unity, godot, etc). Useful for:
- 2d games using bevy's lighting
(orthographic camera, 3d sprites)
- 2d games with easier parallax and scale
(perspective camera, 3d sprites)
- 2d games in a 3d world
(perspective camera, both 3d sprites and meshes)
- 3d games with billboard sprites (a la Delver)
Both meshes and materials are internally cached, so this crate can be used for things like tilemaps without issue.
Example using bevy_sprite3d
:
A more complicated scene: examples/dungeon.rs
. Try
this one with cargo run --example dungeon
.
bevy_sprite3d.cutout.shadows.mp4
Some more examples. These don't use bevy, but demonstrate the effect style:
Check out the examples for details. Tl;dr initialize the plugin with
app.add_plugin(Sprite3dPlugin)
and spawn sprites with
fn setup(
mut commands: Commands,
images: Res<ImageAssets>, // this is your custom resource populated with asset handles
mut sprite_params: Sprite3dParams
) {
// ----------------------- Single Static Sprite ----------------------------
commands.spawn(Sprite3d {
image: images.sprite.clone(),
pixels_per_metre: 400.,
partial_alpha: true,
unlit: true,
..default()
// transform: Transform::from_xyz(0., 0., 0.),
// pivot: Some(Vec2::new(0.5, 0.5)),
// double_sided: true,
}.bundle(&mut sprite_params));
// ------------------- Texture Atlas (Sprite Sheet) ------------------------
let texture_atlas = TextureAtlas {
layout: images.layout.clone(),
index: 3,
};
commands.spawn(Sprite3d {
image: images.sprite_sheet.clone(),
pixels_per_metre: 32.,
partial_alpha: true,
unlit: true,
..default()
// transform: Transform::from_xyz(0., 0., 0.),
// pivot: Some(Vec2::new(0.5, 0.5)),
// double_sided: true,
}.bundle_with_atlas(&mut sprite_params, texture_atlas));
}
One small complication: your image assets should be loaded prior to spawning,
as bevy_sprite3d
uses some properties of the image (such as size and aspect
ratio) in constructing the 3d mesh. Examples show how to do this with Bevy's
States
