The FixedToCamera component enables a Game Object to be rendered relative to the game camera coordinates, regardless of where in the world the camera is. This is used for things like sticking game UI to the camera that scrolls as it moves around the world.
cameraOffset : Phaser.Point
The x/y coordinate offset applied to the top-left of the camera that this Game Object will be drawn at if
The values are relative to the top-left of the camera view and in addition to any parent of the Game Object on the display list.
fixedToCamera : boolean
A Game Object that is "fixed" to the camera is rendered at a given x/y offsets from the top left of the camera. The offsets are stored in the
cameraOffsetproperty, which is initialized with the current object coordinates.
The values are adjusted at the rendering stage, overriding the Game Objects actual world position.
The end result is that the Game Object will appear to be 'fixed' to the camera, regardless of where in the game world the camera is viewing. This is useful if for example this Game Object is a UI item that you wish to be visible at all times regardless where in the world the camera is.
Note that the
cameraOffsetvalues are in addition to any parent of this Game Object on the display list.
Be careful not to set
fixedToCameraon Game Objects which are in Groups that already have
fixedToCameraenabled on them.
The FixedToCamera component postUpdate handler. Called automatically by the Game Object.
