- 30. Initialize LoadContent UnloadContent Update Draw Game1 XNA Game1 Class / Execution Order
- 31. New XNA Project! • Game1() – Class “Game1” constructor Initialize LoadContent UnloadContent Update Draw Game1
- 32. New XNA Project! • Initialize() – Allows the game to perform any initialization it needs to before starting to run. – This is where it can query for any required services and load any non-graphic related content. Calling base.Initialize will enumerate through any component and initialize them as well. Initialize LoadContent UnloadContent Update Draw Game1
- 33. New XNA Project! • LoadContent() – LoadContent will be called once per game and is the place to load all of your content. Initialize LoadContent UnloadContent Update Draw Game1
- 34. New XNA Project! • UnloadContent() – UnloadContent will be called once per game and is the place to unload all content. Initialize LoadContent UnloadContent Update Draw Game1
- 35. New XNA Project! • Update(GameTime gameTime)* – Allows the game to run logic such as updating the world, checking for collisions, gathering input, and playing audio. • Draw(GameTime gameTime)* • This is called when the game should draw itself. * “gameTime” Provides a snapshot of timing values. Initialize LoadContent UnloadContent Update Draw Game1
- 37. New XNA Project! How XNA functions (Game1 Functions) they called?! Initialize LoadContent UnloadContent Update Draw Game1
- 47. Update() vs. Draw() • Update and Draw are called at different rates depending on whether IsFixedTimeStep is true or false. – If IsFixedTimeStep is false, Update and Draw will be called in a continuous loop. – If IsFixedTimeStep is true, Update will be called at the interval specified in TargetElapsedTime, while Draw will only be called if an Update is not due. – If Draw is not called, IsRunningSlowly will be set to true.
