How to detect the leader of a race - Luis- - 14.01.2012

How can I do this? Here's the code.

Yeah, it's long, sorry.

I'm SERIOUSLY needing this, if I get a infraction for bumping this then i'm sorry.

Re: How to detect the leader of a race - Vince - 14.01.2012

That is indeed some really inefficient coding.

To detect the position, you will need to do a few things: First, loop through all players to see who's the furthest in the race. If two or more players are at the same checkpoint, measure the distance between that checkpoint and each player separately to determine who's closer.

pawn Код:

stock Float:GetDistanceBetweenPoints(Float:x1, Float:y1, Float:z1, Float:x2, Float:y2, Float:z2)
{
    x1 -= x2;
    y1 -= y2;
    z1 -= z2;
    return floatsqroot((x1 * x1) + (y1 * y1) + (z1 * z1));
}

loop all players and see what player have highest IsQuading

I'm hopeless with coords, what would I put in the Float

1 etc? I need to learn someday. Thanks!

Anyone else?

I took some time to fix up your function, making it cleaner
