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. Annotations @Override

getFrameId	back to summary
public long getFrameId() Implements com.badlogic.gdx.Graphics.getFrameId. Doc from com.badlogic.gdx.Graphics.getFrameId. Returns the id of the current frame. The general contract of this method is that the id is incremented only when the application is in the running state right before calling the `ApplicationListener#render()` method. Also, the id of the first frame is 0; the id of subsequent frames is guaranteed to take increasing values for 2⁶³-1 rendering cycles.

public Cursor newCursor(Pixmap pixmap, int xHotspot, int yHotspot)

Implements com.badlogic.gdx.Graphics.newCursor.

Doc from com.badlogic.gdx.Graphics.newCursor.

Create a new cursor represented by the com.badlogic.gdx.graphics.Pixmap. The Pixmap must be in RGBA8888 format, width & height must be powers-of-two greater than zero (not necessarily equal) and of a certain minimum size (32x32 is a safe bet), and alpha transparency must be single-bit (i.e., 0x00 or 0xFF only). This function returns a Cursor object that can be set as the system cursor by calling setCursor(Cursor) .

Annotations

@Override

resetDeltaTime	back to summary
public void resetDeltaTime() The delta time for the next frame will be 0. This can be useful if the render thread was blocked for some time to prevent game state or animations from advancing.

setContinuousRendering back to summary

public void setContinuousRendering(boolean isContinuous)

Implements com.badlogic.gdx.Graphics.setContinuousRendering.

Doc from com.badlogic.gdx.Graphics.setContinuousRendering.

Sets whether to render continuously. In case rendering is performed non-continuously, the following events will trigger a redraw:

A call to requestRendering()
Input events from the touch screen/mouse or keyboard
A Runnable is posted to the rendering thread via Application#postRunnable(Runnable). In the case of a multi-window app, all windows will request rendering if a runnable is posted to the application. To avoid this, post a runnable to the window instead.

Life-cycle events will also be reported as usual, see ApplicationListener. This method can be called from any thread.

Doc from com.badlogic.gdx.Graphics.setCursor.

Only viable on the lwjgl-backend and on the gwt-backend. Browsers that support cursor:url() and support the png format (the pixmap is converted to a data-url of type image/png) should also support custom cursors. Will set the mouse cursor image to the image represented by the com.badlogic.gdx.graphics.Cursor. It is recommended to call this function in the main render thread, and maximum one time per frame.
