I need code to synchronize wheel spin and wheel's speed.

Not sure if you want it to be physically accurate, but here is something to mess around with. If you want the wheel to spin at a 1 to 1 distance as the speed is moving you'll have to do something else, but for now I am going to bed. You need an int timer for this.

Code: Select all

int rot = ceil(xvelocity/15);
xvelocity*=.99;

timer+=xvelocity;
if(timer>=5)
{
    animpos=((int)animpos+nframes-(int)max(1, rot))%nframes;
    timer=0;
}

generally looks not bad but I hoped that wheel will gradually rotate faster and faster but there are only few speeds when wheel accelerates, but still it looks convincingly, I can't do better even can't understand that code I wonder for example what is function ceil.

Sounds like it's kind of like the round function. (I think it's short for ceiling, but I'm not sure.)

I learned that you can simply put a function name in the search box on the home page and it will give you a definition.

haha ceil = ceiling xD

Well....
