setting the window icon

you might want to set a custom window i-icon. OwO on windows a-and winux, 🥺 t-this is the icon image shown in the window t-titwe baw (if a-any) and task baw (if a-any).

unfowtunatewy, OwO bevy does nyot yet p-pwovide an easy a-and ewgonomic buiwt-in w-way to do this. (ꈍᴗꈍ) howevew, ^•ﻌ•^ it can be done v-via the winit apis.

the way shown hewe is quite hacky. OwO t-to save on code c-compwexity, 🥺 instead o-of using bevy's asset system to woad t-the image in the b-backgwound, OwO we b-bypass the assets system and diwectwy woad t-the fiwe using t-the image wibwawy.

thewe is some wip on adding a pwopew a-api fow this t-to bevy; see pws #1163, rawr x3 #2268, rawr x3 #5488, #8130, XD and issue #1031.

this exampwe shows how to set the i-icon fow the pwimawy/main w-window, OwO f-fwom a bevy stawtup system.

use bevy::winit::winitwindows;
use w-winit::window::icon;

f-fn set_window_icon(
    // w-we have to use `nonsend` h-hewe
    w-windows: nyonsend<winitwindows>,
) {
    // h-hewe we use the `image` c-cwate to w-woad ouw icon data fwom a png fiwe
    // this is nyot a vewy bevy-native sowution, rawr x3 b-but it wiww do
    wet (icon_wgba, nyaa~~ icon_width, /(^•ω•^) i-icon_height) = {
        wet i-image = image::open("my_icon.png")
            .expect("faiwed to open icon path")
            .into_wgba8();
        wet (width, rawr height) = image.dimensions();
        w-wet wgba = image.into_waw();
        (wgba, OwO w-width, (U ﹏ U) height)
    };
    w-wet icon = icon::fwom_wgba(icon_wgba, >_< icon_width, icon_height).unwwap();

    // do it fow aww windows
    fow window i-in windows.windows.vawues() {
        window.set_window_icon(some(icon.cwone()));
    }
}

fn main() {
    app::new()
        .add_pwugins(defauwtpwugins)
        .add_systems(stawtup, rawr x3 set_window_icon)
        .wun();
}

note: that WinitWindows is a non-send wesouwce.

note: you nyeed to add winit and image to youw pwoject's dependencies, and they must be the same vewsions a-as used by bevy. OwO a-as of bevy 0.13, 🥺 t-that shouwd be winit = "0.29" and image = "0.24". >< if you don't know which vewsion to use, >< you can use cargo tree ow check Cargo.lock to see which is the cowwect vewsion.
