What is the difference between sprites and textures?
Maybe I can pass the “bitmap” there. What is a bitmap?
They all seem to be the same as 2D images.
The sprite actually draws the texture on the screen, or just a specific rectangle of the texture. The sprite can be scaled, rotated, positioned, tilted, colored (colored), etc.
Multiple sprites can share the same texture. No matter how many sprites use the same texture, the texture will only be loaded into memory. In addition, with CCSpriteBatchNode, you can “batch” all sprites with the same texture For better performance.
Bitmap is a general term for computer graphics, where each pixel is represented by one or more bits. There is also the popular image format BMP on Windows. These Most people only say “images” because there are other forms of “bitmaps” that are not images. For example, in AI code, you often use bitmaps (bit arrays) to represent AI status information or for games Pathfinding algorithm for all regions of the world. That is, every region in the world may have a “blocking” bit or a “resource” bit, which can help AI make decisions.

I recently started to pay attention to cocos2d game development.

Textures are in-memory images that the device can draw on the screen.
