Method Detail

getRawDeltaTime

public float getRawDeltaTime()

Specified by:

getRawDeltaTime in interface Graphics

Returns:

the time span between the current frame and the last frame in seconds, without smoothing

getDensity

public float getDensity()

Description copied from interface: Graphics

This is a scaling factor for the Density Independent Pixel unit, following the same conventions as android.util.DisplayMetrics#density, where one DIP is one pixel on an approximately 160 dpi screen. Thus on a 160dpi screen this density value will be 1; on a 120 dpi screen it would be .75; etc. If the density could not be determined, this returns a default value of 1. Depending on the underlying platform implementation this might be a relatively expensive operation. Therefore it should not be called continously on each frame.

Specified by:

getDensity in interface Graphics

Returns:

the Density Independent Pixel factor of the display.

getBackBufferScale

public float getBackBufferScale()

Specified by:

getBackBufferScale in interface Graphics

Returns:

amount of pixels per logical pixel (point)
