All above versions sux, not because they are wrong but because they are damn slow...
You better use this:

Код:

#define IsToPoint(%0,%1,%2,%3,%4,%5,%6) \
((((%0) - (%3)) * ((%0) - (%3))) + (((%1) - (%4)) * ((%1) - (%4))) + (((%2) - (%5)) * ((%2) - (%5))) <= ((%6) * (%6))) // ******'s macro for distance checking

stock IsVehicleNearPos(weed, Float: x, Float: y, Float: z, Float: dist)
{
	new
	  Float: vX,
	  Float: vY,
	  Float: vZ;
	GetVehiclePos(weed, vX, vY, vZ);
	return IsToPoint(x,y,z,vX,vY,vZ,dist);
}

Usage: IsVehicleToPos(veh, x, y, z, dist)

Have fun
