Enum ScreenCommand 

pub enum ScreenCommand {
    Show(AssetId),
    Hide,
    Toggle(AssetId),
    Push(AssetId),
    Clear,
}

Runtime-only event sent by UiInputSystem when a screen:* action fires. UiInputSystem reads these from its Events<ScreenCommand> queue on the next step and applies the stack transition. World authors never declare this type directly.

Variants

Show(AssetId)

Replace the top of the stack (menu navigation).

Hide

Pop the top of the stack, revealing what was beneath.

Toggle(AssetId)

Pop if the screen is topmost, push it otherwise.

Push(AssetId)

Push on top of whatever is already showing.

Clear

Empty the stack (a scene change dismisses every open screen).
