engine.getRenderWidth() and .getRenderHeight() don't take engine.getHardwareScaleLevel() into account


Recommended Posts

In babylon v2.5, engine.getRenderWidth() and .getRenderHeight() return doubled what's expected on retina displays. Scene.pointerX and .pointerY do not, so in order to match screen clicks to objects in the scene, you need to multiply the renderWidth and height by engine.getHardwareScalingLevel(). 

This means that the preferred way of getting the screen coordinates of an object:

        camera.viewport.toGlobal(engine.getRenderWidth(), engine.getRenderHeight())

Will fail on retina displays.

It seems more intuitive for getRenderWidth and height to do the scaling themselves. (Or, as has been mentioned before, I think, adding a specific object to screen method on scene or engine).
