Using arrays to blit multiple objects in pygame?

Question

I was looking for a faster way to blit multiple objects in pygame than the traditional blitting method, in which you have an array or list, and you use a for loop to go and insert each image at its position.

Maybe there is a way of blitting the whole array at once, without having to go value by value throughout the whole array?

Thanks for the ideas and help!

No, I dont even know what that is. I have always used the blits, so for example: DisplaySurf.blit(myImage, (x,y)) — v2rwbtc6

pygame.sprite.Group should do the trick! Also, pygame.sprite.Group has a draw function that draws all sprites in a group. https://www.pygame.org/docs/ref/sprite.html#pygame.sprite.Group

use pygame.sprite.Group or multithread the blit method. In pygame 1.9.2alpha, it releases the python gil and allows multi-cpu rendering.

Also look up for pygame dirty rendering. Depending on what you want to draw, this can give you significant speed increase.
