Transitions

Transitions animate between scenes. Pass one to SceneManager.transition_to_scene:

manager.transition_to_scene(
    "menu",
    bf.transition.FadeColor(0.5, color=(0, 0, 0)),
)

Built-in transitions

Class	Effect
Fade	Cross-fade source → destination
FadeColor	Fade through a solid color
GlideLeft / GlideRight	Slide
CircleIn / CircleOut	Circular wipe

All take duration (seconds) and optional easing.

While a transition runs, player input events are suppressed by the active scene.
