Glossary — wiki
A short list of words related to pygame, with brief definitions, arranged alphabetically.
- to copy a large section of image data from one surface to another. This is how you draw a sprite on the screen. A blit can do some blending, which means not just overwriting the old image data, but changing it instead. This can be used to implement semi-transparent objects.
- Dirty Rects
- A rectangle area of what has changed on the screen. Called dirty rects because the rectangle has been dirtied - modified. Useful for speeding up screen redraws, because if only part of the screen has changed, then you only need to update part of the screen.
- what the user sees.
- a visual object, capable of moving around the screen and being animated. Pygame provides a simple sprite class and several Group classes to organize sprites.
- an object that represents graphical information. Loaded image data (.png, .jpg, .bmp) is stored in, and Surfaces can be written out to image files. In Pygame, the screen is a surface too.
