ViewportTransform class

Constructors

ViewportTransform(Vector2 extents, Vector2 center, double scale)

Properties

center → Vector2

center of the viewport.

final

extents → Vector2

This is the half-width and half-height. This should be the actual half-width and half-height, not anything transformed or scaled.

final

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

scale ↔ double

Returns the scaling factor used in converting from world sizes to rendering sizes.

getter/setter pair

translation ↔ Vector2

The current translation is the difference in canvas units between the actual center of the canvas and the currently specified center. For example, if the actual canvas center is (5, 5) but the current center is (6, 6), the translation is (1, 1).

getter/setter pair

yFlip ↔ bool

if we flip the y axis when transforming.

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

screenToWorld(Vector2 argScreen) → Vector2

Takes the screen coordinates and return the corresponding world coordinates.

setCamera(double x, double y, double s) → void

Sets the transform's center to the given x and y coordinates, and using the given scale.

toString() → String

A string representation of this object.

inherited

worldToScreen(Vector2 argWorld) → Vector2

Takes the world coordinates and return the corresponding screen coordinates.

Operators

operator ==(Object other) → bool

The equality operator.
