Select File → New Project from the toolbar. 0). Check that you’re happy with the project name and file location, and then click OK. Within the game class created by the template, you will notice a constructor and five overridden functions for initialization, content load, content unload, update, and draw.

XNA Sprite Source Data Data Type bitmap Texture2D location Rectangle origin Vector2 XNA Sprite Destination Data Data Type screen location and scale Vector2 and float or destination rectangle Rectangle rotation float color RGBA color depth float effects SpriteEffects In addition to the bitmap and location, it is also useful to take note of the sprite origin. By default, the origin is in the upper-left corner of the sprite (0, 0). The origin is relative to the x-y location coordinates. 6). 1. What Is a Sprite?

For example, if you know your path-finding algorithm may take up to 60 ms, you could pause the path-finding algorithm after 10 ms and then resume the path-finding calculations on the next frame. Depending on your system architecture, a better option may be to offload the intensive calculations to other nonblocking processor threads. Ensuring background operations do not prevent the game Draw function from occurring is especially important when saving games or querying remote databases. In these circumstances, you should always use asynchronous function calls if they are available.
