1. How many cop cars will there be?

Код:

new copcars[0];

2. Which car is a cop car? However many lines of code there are with "copcars[?]", is your number of vehicles for number 1.

Код:

copcars[0] = AddStaticVehicle(...)

3. How do you define what is a cop car?

Код:

stock IsCopCar(vehicleid)
{
	for(new i=0; i<sizeof(copcars); i++)
	{
	  if(copcars[i] == vehicleid) return 1;
	}
	return 0;
}

4.

Код:

if(oldstate == PLAYER_STATE_ONFOOT && newstate == PLAYER_STATE_DRIVER && IsCopCar(GetPlayerVehicleID(playerid)))
{
SendClientMessage(playerid,0xF08080AA,"You have been ejected.");
RemovePlayerFromVehicle(playerid);
return 1;
}
