Скачать или смотреть Data-Driven Game Dev — 04: Input Manager & Player Control (WASDArrows + Smooth Accel)

Data-Driven Game Dev
We’re building a small, shippable game engine in TypeScript—data in components, behavior in systems, and a renderer you can swap later. Clear steps, practical outcomes, no magic.

This episode
We add a typed, layout-independent Input Manager and let entities declare their own key bindings with a Controller component (WASD vs Arrow keys). Intent lives in DesiredMove, motion tuning in Locomotion, and a new SteeringSystem accelerates/decelerates velocity for smooth, deterministic movement—cleanly slotted into the fixed-timestep loop.

What you’ll learn

Building a “dumb” input service: down / pressed / released
Strong typing for KeyboardEvent.code with a full key catalog
Per-entity key bindings via a Controller component
Splitting intent (DesiredMove), tuning (Locomotion), and state (Velocity)
Steering toward a target velocity (accel/decel/drag) without jitter

Stack
TypeScript • HTML5 Canvas • ECS (custom) • Bun (dev server)
