Module transitions 

Screen Transition Manager — handles visual transitions between game screens.

Supports multiple transition types: FadeBlack, Dissolve, Slide, ZoomIn, ChaosWipe. Each transition captures the outgoing screen state, tweens a visual effect, and reveals the incoming screen.

Usage

use proof_engine::game::transitions::*;

let mut tm = TransitionManager::new();
tm.start(TransitionType::FadeBlack {
    out_time: 0.2, hold_time: 0.05, in_time: 0.2,
});
// Each frame:
tm.tick(dt);
if tm.should_swap_state() {
    // swap game state here
    tm.acknowledge_swap();
}
// Render the transition overlay:
let overlay = tm.render_overlay(screen_width, screen_height);

Structs

TransitionQueue

A queue of pending transitions. Useful when multiple transitions might be requested in quick succession (e.g. combat → floor nav → shop).

TransitionRequest

Queued transition request — allows scheduling transitions from game logic.

TransitionStats

Per-frame statistics.

Enums

TransitionEasing

Easing functions for transition curves.

TransitionEffect

Which visual effect the renderer should use.

TransitionState

Current phase of a screen transition.

TransitionType
