Sprites don't run!

SDL Development
1

Hi to all, I have a big problem. I’m developing a small SDL demo: a
background with 4 sprites moving and rotating above it. The problem is the
speed; my sprites move very slowly. I use 640x480x16 video mode and a clycle
like:

cycle {

write sprite 1
write spirte 2
write sprite 3
rotate sprite 4
write sprite 4

HandleEvent();

pos_sprite1++
pos_sprite2++
pos_sprite3++
pos_sprite4++

}

That’s all I can undestand where is the problem. Does anibody know where I
can download a demo (or a gamer) with source that use a lot of fast moving
sprites?
Thank a lot.
Bye, Andrea

My game BugSquish is fairly simple, and has numerous sprites on the
screen at once. (MOST of my games have lots of sprites on the screen
at once :wink: … but BugSquish was the simplest game to create)

You may want to look at test/testsprite.c in all SDL source package.
maybe you also want to look at the redraw and update part again
if your program runs too slow.
