Class CapacitorNode¶

import { CapacitorNode } from 'scenerystack/scenery-phet';

Constructor¶

new CapacitorNode( circuit, modelViewTransform, plateChargeVisibleProperty, electricFieldVisibleProperty, options )¶

Instance Methods¶

dispose()¶

@public

frontSideContainsSensorPoint( globalPoint )¶

Returns true if the front side contains the specified point, used for voltmeter probe hit testing. @param {Vector2} globalPoint @returns {boolean} @public

backSideContainsSensorPoint( globalPoint )¶

Returns true if the back side contains the specified point, used for voltmeter probe hit testing. @param {Vector2} globalPoint @returns {boolean} @public

getTopPlateClipShapeToGlobal()¶

Returns the clipping region for the top shape, in global coordinates, used to show wires or electrons flowing in/out of the capacitor. @returns {Shape} @public

getBottomPlateClipShapeToGlobal()¶

Returns the clipping region for the bottom shape, in global coordinates, used to show wires or electrons flowing in/out of the capacitor. @returns {Shape} @public

updateGeometry()¶

Update the geometry of the capacitor plates. @private

getPlatesBounds()¶

Get the bound of the capacitor from the plates. Allows for bounds to be passed into the canvas node before the children are added to the view. @public

@returns {Bounds2}
