Camera class

Camera class for controlling the viewport

The camera determines what part of the world is visible and how it's displayed.

Constructors

Camera({Offset position = Offset.zero, double zoom = 1.0, double rotation = 0.0, Size viewportSize = Size.zero, double minZoom = 0.1, double maxZoom = 10.0, bool smoothing = false, double smoothingFactor = 0.1})

Create a camera

Properties

hashCode → int

The hash code for this object.

no setter, inherited

maxZoom ↔ double

Maximum zoom level

getter/setter pair

minZoom ↔ double

Minimum zoom level

getter/setter pair

position ↔ Offset

Camera position in world space

getter/setter pair

rotation ↔ double

Rotation in radians

getter/setter pair

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

smoothing ↔ bool

Whether to smooth camera movement

getter/setter pair

smoothingFactor ↔ double

Smoothing factor (0.0 - 1.0, higher = smoother but more lag)

getter/setter pair

viewportSize ↔ Size

Viewport size (set by rendering engine)

getter/setter pair

zoom ↔ double

Zoom level (1.0 = normal, >1.0 = zoom in, <1.0 = zoom out)

getter/setter pair

Methods

applyTransform(Canvas canvas, Size size) → void

Apply camera transform to canvas

follow(Offset target, {Offset? deadZone, bool smooth = true}) → void

Follow a target with optional dead zone

getVisibleBounds() → Rect

isVisible(Offset point) → bool

Check if a point is visible

lookAt(Offset target, {bool smooth = false}) → void

Look at a specific point

moveBy(Offset delta) → void

Move the camera by an offset

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

reset() → void

Reset camera to default values

screenToWorld(Offset screenPos) → Offset

Convert screen coordinates to world coordinates

setPosition(Offset newPosition, {bool smooth = false}) → void

shake(double intensity, double duration) → void

Shake the camera

toString() → String

A string representation of this object.

inherited

update(double deltaTime) → void

Update camera (for smooth movement)

worldToScreen(Offset worldPos) → Offset

Convert world coordinates to screen coordinates

zoomBy(double factor) → void
