[PyGame] I found a way to generate sprites without .blit. Is it effecient?

[Windspar]

That very expensive. Use surface to store created image. With surface use set_at. It be more efficient then pygame draw rects for per pixel. This way you do the math once. Then blit surface is very fast.

The old ways won't work the same. Program languages have separated core programming and graphics. This allow programs language to be more flexible. So you can choose between sdl, opengl, or etc.

Here an example I made a while back.
