Camera2D

The orthographic camera of a Scene2D. Every scene owns one — access it as scene.camera; you never construct a Camera2D yourself.

At a glance

TypeScript
const scene = new Scene2D()
scene.camera.zoom = 2                        // 2× magnification — pixel-art friendly

// keep the camera on the hero, with a little easing
setLoop(dt => {
  scene.camera.position = scene.camera.position.lerp(hero.worldPosition, 10 * dt)
})

Transform

TypeScript
camera.position = [x, y]     // world units — the point at the center of the screen
camera.zoom = 2              // magnification; at 1, 1 world unit = 1 logical px. Default 1
camera.rotation = 15         // degrees, CCW. Default 0

Getters return fresh values (camera.position.x = 3 is a no-op — see conventions).

Note

there is no built-in follow(). Track a node from setLoop (as above) or with a small update(dt) aspect — nothing to dispose when the target goes away.

Screen ↔ world

TypeScript
camera.screenToWorld(screenX, screenY): Vec2   // logical px → world units
camera.worldToScreen(worldX, worldY): Vec2     // world units → logical px

screenToWorld is the pairing for tap handling: convert ev.clientX/clientY and feed the result to scene.pick() or Physics2D.overlapPoint(). Remember the sign flip: screen Y points down, world Y points up — the conversion handles it for you.
