Methods

init(world, opt_options=)

Initializes Oscillator.
Parameters:
Name Type Argument Default Description
world Object An instance of World.
opt_options= Object <optional>
 A map of initial properties.
opt_options.initialLocation Object <optional>
 The center of the world The object's initial location.
opt_options.lastLocation Object <optional>
 {x: 0, y: 0} The object's last location. Used to calculate angle if pointToDirection = true.
opt_options.amplitude Object <optional>
 {x: world width, y: world height} Sets amplitude, the distance from the object's initial location (center of the motion) to either extreme.
opt_options.acceleration Object <optional>
 {x: 0.01, y: 0} The object's acceleration. Oscillators have a constant acceleration.
opt_options.aVelocity Object <optional>
 new Vector() Angular velocity.
opt_options.isStatic boolean <optional>
 false If true, object will not move.
opt_options.perlin boolean <optional>
 false If set to true, object will use Perlin Noise to calculate its location.
opt_options.perlinSpeed number <optional>
 0.005 If perlin = true, perlinSpeed determines how fast the object location moves through the noise space.
opt_options.perlinTime number <optional>
 0 Sets the Perlin Noise time.
opt_options.perlinAccelLow number <optional>
 -2 The lower bound of acceleration when perlin = true.
opt_options.perlinAccelHigh number <optional>
 2 The upper bound of acceleration when perlin = true.
opt_options.offsetX number <optional>
 Math.random() * 10000 The x offset in the Perlin Noise space.
opt_options.offsetY number <optional>
 Math.random() * 10000 The y offset in the Perlin Noise space.
opt_options.width number <optional>
 20 Width.
opt_options.height number <optional>
 20 Height.
opt_options.color Array <optional>
 200, 100, 0 Color.
opt_options.borderWidth number <optional>
 this.width / 4 Border width.
opt_options.borderStyle string <optional>
 'solid' Border style.
opt_options.borderColor Array <optional>
 255, 150, 0 Border color.
opt_options.borderRadius number <optional>
 100 Border radius.
opt_options.boxShadowSpread number <optional>
 this.width / 4 Box-shadow spread.
opt_options.boxShadowColor Array <optional>
 147, 199, 196 Box-shadow color.
