empty : boolean Determines whether or not this Ellipse object is empty. Will return a value of true if the Ellipse objects dimensions are less than or equal to 0; otherwise false.If set to true it will reset all of the Ellipse objects properties to 0. An Ellipse object is empty if its width or height is less than or equal to 0. Gets or sets the empty state of the ellipse. Source code: geom/Ellipse.js (Line 276)

overlap(displayObject) → {boolean} Checks to see if the bounds of this Game Object overlaps with the bounds of the given Display Object,which can be a Sprite, Image, TileSprite or anything that extends those such as Button or provides a getBounds method and result. This check ignores the hitArea property if set and runs a getBounds comparison on both objects to determine the result. Therefore it's relatively expensive to use in large quantities, i.e. with lots of Sprites at a high frequency.I

maxParticleScale : number The maximum possible scale of a particle. This is applied to the X and Y axis. If you need to control each axis see maxParticleScaleX. Default Value 1 Source code: particles/arcade/Emitter.js (Line 75)

cropRect : Phaser.Rectangle The Rectangle used to crop the texture this Game Object uses.Set this property via crop.If you modify this property directly you must call updateCrop in order to have the change take effect. Source code: gameobjects/components/Crop.js (Line 24)

autoCull : boolean A Game Object with autoCull set to true will check its bounds against the World Camera every frame.If it is not intersecting the Camera bounds at any point then it has its renderable property set to false.This keeps the Game Object alive and still processing updates, but forces it to skip the render step entirely. This is a relatively expensive operation, especially if enabled on hundreds of Game Objects. So enable it only if you know it's required,or you have tested perfor

centerX : number The center x coordinate of this Group. It is derived by calling getBounds, calculating the Groups dimensions based on itsvisible children. Inherited From Phaser.Group#centerX Source code: core/Group.js (Line 2705)

<constant> MATRIX : integer Game Object type. Source code: Phaser.js (Line 262)

removeKey(keycode) Removes a Key object from the Keyboard manager. Parameters Name Type Description keycode integer The keycode of the key to remove. Source code: input/Keyboard.js (Line 191)

minParticleAlpha : number The minimum possible alpha value of a particle. Default Value 1 Source code: particles/arcade/Emitter.js (Line 98)

dragStopBlocksInputUp : boolean If enabled, when the Sprite stops being dragged, it will only dispatch the onDragStop event, and not the onInputUp event. If set to false it will dispatch both events. Source code: input/InputHandler.js (Line 187)
