pawn Код:

if (strcmp("/DIS", cmdtext, true)==0)
    {
        SendClientMessage(playerid, 0x00FFFFFF, "Bait-Car Disabled.");
        SetVehicleParamsEx(BC1, 0, 1, 0, 1, 0, 0, 0);
        SetVehicleParamsEx(BC2, 0, 1, 0, 1, 0, 0, 0);
        SetVehicleParamsEx(BC3, 0, 1, 0, 1, 0, 0, 0);
        return 1;
    }

This will turn off the engine for all the vehicles and I suggest to use a command proccecor to add params feature and use to advence your script,then you can make for example /dis [bcid(1-3)] instead of one command that turns off the engine for all the vehicles.

pawn Код:

DestroyVehicle(BC1);
DestroyVehicle(BC2);
DestroyVehicle(BC3);

For that case I suggest to check if the vehicle exist and/or destroy only one vehicle,the one that the command is used on.
for example /bc1 will destroy only vehicle BC1.

anyhow,nice idea.
