Time Runtime API

Purpose

Time helpers expose frame delta and fixed-step timing for scripts.

Time Runtime API explains behavior, constraints, and practical usage so implementation decisions stay consistent across scripts and scenes.

Types

RuntimeWindowScriptContext

let dt = delta_time!(ctx.run);with_node_mut!(ctx.run, Node2D, ctx.id, |node| {    node.position.x += 220.0 * dt;});

Use delta time in on_update for frame-rate independent motion.

Use fixed timing with on_fixed_update for deterministic physics-style work.

Store time values before entering ctx.run borrow closures.

Project fixed update target comes from project.toml runtime settings.
