bevy_cursor_kit

Summary

bevy_cursor_kit is a crate for Bevy apps that lets you load cursor assets in various formats and use them as custom CursorIcons.

Features

.CUR and .ANI binary formats

Load the classic Microsoft Windows .CUR and .ANI cursor file formats.

• .CUR files can be used for static cursor icons like a grabbing hand.
• .ANI files can be used for animated cursor icons like an hourglass.

.cur.json ,.cur.ron, .cur.toml, .ani.json ,.ani.ron, .ani.toml text formats

Text-based versions of the classic .CUR static cursor and .ANI animated cursor file formats.

Write your cursors in JSON, RON, or TOML and bevy_cursor_kit can load them for you.

Static cursor

(
    image: (
        path: "path/to/sprite-sheet.png",
    ),
    texture_atlas_layout: (
        tile_size: (32, 32),
        columns: 20,
        rows: 10,
    ),
    hotspots: (
        default: (0, 0),
        overrides: {
            11: (32, 32),
            95: (32, 8),
        },
    ),
)

Animated cursor

(
    image: (
        path: "path/to/sprite-sheet.png",
    ),
    texture_atlas_layout: (
        tile_size: (32, 32),
        columns: 2,
        rows: 2,
    ),
    hotspots: (
        default: (0, 0),
    ),
    animation: (
        repeat: Loop,
        clips: [
            (
                atlas_indices: [3, 0, 1, 2],
                duration: PerFrame(75),
            ),
            (
                atlas_indices: [2],
                duration: PerFrame(5000),
            ),
        ],
    )
)

Quick start

Add the asset plugin for asset loader support:

use bevy_cursor_kit::prelude::*;

app.add_plugins(CursorAssetPlugin);

Load a static cursor or an animated cursor:

let handle = asset_server.load("example.CUR");

When the asset is ready, use its image when creating a custom CursorIcon component on your Windows:

let Some(cursor) = static_cursors.get(&handle) else {
  // ...
};

commands
  .entity(window)
  .insert(CursorIcon::Custom(
    CustomCursorImageBuilder::from_static_cursor(cursor, None).build(),
  ));

If you want to use the text-based formats, enable the serde_json_asset, serde_ron_asset, or serde_toml_asset feature in your Cargo.toml and load away:

let handle = asset_server.load("example.cur.ron");

Version compatibility

Warning

[email protected] is compatible with [email protected] and allows you to decode .CUR and .ANI files. Most of the benefits of this crate will come when [email protected] is released, so use main if you can.
