Advanced camera zoom options #212

Closed bitbrain closed 4 years ago

bitbrain commented 4 years ago

Motivation

We currently can set the camera zoom via defaultZoomFacor property. However, this is very bad for various reasons:

does not re-adjust with changing resolution
difficult API - choosing a value is a guessing game

Solution

Change the zoom API to the following:

setZoom(0.2f, ZoomMode.TO_VALUE);
setZoom(256f, ZoomMode.TO_WIDTH);
setZoom(128f, ZoomMode.TO_HEIGHT);

(by default, setZoom will use TO_VALUE)

TO_VALUE the zoom value provided is being used as camera zoom
TO_WIDTH the zoom value is being calculated dynamically based on the current camera width
TO_HEIGHT the zoom value is being calculated dynamically based on the current camera height
