8_ Game Loop

``` while(true) {Event*Event=waitforevent (); Dispatchevent (Event);} while(true) {processinput ();  Update (); Render ();} The game loop is executed during the game run, each cycle will process user input, update the game state, render the scene, etc. Record the cycle time to control the rhythm (rate) of the game.
