in a racing game, can somebody explain how to calculate who's in first, second, third, etc?
the only way i can think of is making hidden plains every few feet and counting up collisions, and that would take too long for me.

You're gonna need to use waypoints... Don't be scared off by the fancy name, all it is is a way of checking if the object(s) have reached/passed a particular point in the game...

Ie, you store the finish position ( X and Z coords ) in a couple of variables, then check to see if each of the racers have reached/passed that spot... If they have, then you rank them according to what order they reached that spot in...

Yep

That would be a good idea anyway, as you can check if the player is going in the wrong direction ( if they're facing the wrong checkpoint, ie, the one that is meant to be behind them ), and you can do split times for laps, and also set up AI to use those very same WayPoints so that they have to travel through them ( ie, stay on-track )...

how would i make the waypoints diagonal instead of straight along the axises, i've been using if object position x(1)<100 and object position x(1)>50 etc to make a rectangular area. is there any snippet to make this easier?

you might find it easier to use actual (hidden) objects and just check collision with them, then your waypoints can be any shape/size and positioned/rotated in any way i might try and get a simple racing game working, maybe i should start now...

In the beginning, the universe was created...
This made alot of people very angry and it has been widely regarded as a bad idea...
