我试图通过Bevy文档，并注意到我绝对不能运行一个例子或基本的应用程序超过5秒没有得到错误打破执行。文档的设置之外是否有什么特殊的东西需要运行，或者Bevy只是为最新的Windows 11 + Geforce RTX 2060机器而坏了?
无论我运行哪个示例或尝试遵循文档，这种情况总是发生:

我从书中编写的Rust代码(请注意，这也发生在大量repo未触碰的示例代码中):
use bevy::prelude::*;
pub struct HelloPlugin;
struct GreetTimer(Timer);
#[derive(Component)]
struct Person;
#[derive(Component)]
struct Name(String);
impl Plugin for HelloPlugin {
fn build(&self, app: &mut App) {
// the reason we call from_seconds with the true flag is to make the timer repeat itself
app.insert_resource(GreetTimer(Timer::from_seconds(2.0, true)))
.add_startup_system(add_people)
.add_system(greet_people);
}
}
fn greet_people(time: Res<Time>, mut timer: ResMut<GreetTimer>, query: Query<&Name, With<Person>>) {
// update our timer with the time elapsed since the last update
// if that caused the timer to finish, we say hello to everyone
if timer.0.tick(time.delta()).just_finished() {
for name in query.iter() {
println!("hello {}!", name.0);
}
}
}
fn add_people(mut commands: Commands) {
commands
.spawn()
.insert(Person)
.insert(Name("Elaina Proctor".to_string()));
commands
.spawn()
.insert(Person)
.insert(Name("Renzo Hume".to_string()));
commands
.spawn()
.insert(Person)
.insert(Name("Zayna Nieves".to_string()));
}
fn main() {
App::new()
.add_plugins(DefaultPlugins)
.add_plugin(HelloPlugin)
.run();
}
您可以从输出中看到，我试图从书中运行my_bevy_game示例，但是wgpu的这个完全相同的问题发生在我迄今为止运行的所有示例上。你要怎么做才能跟贝弗合作?
—edit—
看来这是一个dx12问题，WGPU需要解决。Bevy问题中提出的解决方案不适用于我和其他人的机器。看来贝弗"坏了"。不可挽回的暂时，由于依赖于WGPU。
这看起来像是一个bug，请参阅问题#4461 of bevy, bug位于wgpu:
你可以尝试临时使用最新的wgpu版本:
[patch.crates-io]
wgpu = { git = "https://github.com/gfx-rs/wgpu" }
# or
wgpu = { git = "https://github.com/gfx-rs/wgpu" , rev = "3d10678a91b78557b0dea537407eb4a4ff754872" }
