im just constructing the hud for my game right now and i am using sprites and images

now i was wondering which method of 2d graphics creates the most overhead

i would imagine the sprites do but repasting the image each cycle must be somewhat expensive as well

thanks

I've found with dbpro it depends on the number and size of images, it's proberly dependent on hardware as well.

Try it and see which works faster. Even if sprites are a little slower it might be worth it for the convience or not having to manage pasting images every loop.


it's cool to hate

Do you really have to do it with sprites or images? 3D textured plains work much better because they are so fast...or is your game already in 2D. If so, sprites are most likely faster.

Pretty much identical in speed once you disable the backsave option on sprites.

One advantage that sprites have though is that you can fade/zoom/rotate them into place or even add other effects to them.

Of course, there's nothing there that couldn't also be done using a 3D plain, and a plain wouldn't have to be resized depending on the screen resolution.
