MainGameLoop• Every game consists of a main game loopwhich performs a series of tasks every frame

•Main game loop runs continuously during the game. It processes input, updates the

game, and renders the output

Maingameloop

TimeandSpeedinMainGameLoop•Most of the tasks are performed within a single frame (single iteration of main game

loop)while some tasks span over multiple frames

• Frame Per Second (FPS): The number of times the main game loop is executed in one

second and it varies from system to system

• High performance systems will have higher frame rates, so game time and speed must

be consistentacross different types of systems


InputandOutputinMainGameLoop• Input is read only once per frame per device but it can be processed either in single

frameor over multiple frames

• Output is rendered and drawn every frame and it is done after updating the state of

the game (after performingall the other tasks)
