Struct bevy_window::WindowPlugin

pub struct WindowPlugin {
    pub primary_window: Option<Window>,
    pub exit_condition: ExitCondition,
    pub close_when_requested: bool,
}

A Plugin that defines an interface for windowing support in Bevy.

Fields

primary_window: Option<Window>

Settings for the primary window. This will be spawned by default, if you want to run without a primary window you should set this to None.

Note that if there are no windows, by default the App will exit, due to exit_on_all_closed.

exit_condition: ExitCondition

Whether to exit the app when there are no open windows.

If disabling this, ensure that you send the bevy_app::AppExit event when the app should exit. If this does not occur, you will create ‘headless’ processes (processes without windows), which may surprise your users. It is recommended to leave this setting to either ExitCondition::OnAllClosed or ExitCondition::OnPrimaryClosed.

ExitCondition::OnAllClosed will add exit_on_all_closed to CoreSet::Update. ExitCondition::OnPrimaryClosed will add exit_on_primary_closed to CoreSet::Update.

close_when_requested: bool

Whether to close windows when they are requested to be closed (i.e. when the close button is pressed).

If true, this plugin will add close_when_requested to CoreSet::Update. If this system (or a replacement) is not running, the close button will have no effect. This may surprise your users. It is recommended to leave this setting as true.

Trait Implementations

impl Default for WindowPlugin

fn default() -> Self

Returns the “default value” for a type.

impl Plugin for WindowPlugin

fn build(&self, app: &mut App)

Configures the App to which this plugin is added.

fn setup(&self, _app: &mut App)

Runs after all plugins are built, but before the app runner is called. This can be useful if you have some resource that other plugins need during their build step, but after build you want to remove it and send it to another thread.

fn name(&self) -> &str

Configures a name for the Plugin which is primarily used for checking plugin uniqueness and debugging.

fn is_unique(&self) -> bool

If the plugin can be meaningfully instantiated several times in an App, override this method to return false.
