Pygame: Map Tile or Large Image

Question

I’m trying to decide if it’s better to use a pre-processed large image to scroll through a card game or to display separate fragments on each frame. I tried to program the game in both directions and I do not see an obvious difference in speed, but this may be due to my lack of experience.

Also, is there a speed for memory not to use a pre-rendered map?

Answer 1

The only reason I can think about choosing one over the other on modern equipment (something as fast and with the same number of sheep as, say, the iPhone) would be technical, which would make it easier to use the game code . There is not much to distinguish them.

The only exception I can think of is that if you use a really massive background and render fragments in the GPU, the tiles may be textures and you will get a little speed because you don't have to push a lot of data between the processor and gpu per frame, and it will use very little video memory.

Answer 4

Depending on the size of the map that you want to create, however, using real technology it is very difficult to see that the tiled-out map will take longer than expected, the tile-based games are almost extinguished, however, it’s always good practice and the starting point for game programming world.
