Help|error 029: invalid expression, assumed zero - DVDXD - 30.06.2011

Hey,
i wanted to do that if someone press the "Fire" key- he get Nitro.
But when i tried to compile that it said me:

Код:

C:\Documents and Settings\David\Desktop\Server\gamemodes\David.pwn(1402) : error 029: invalid expression, assumed zero

My public OnPlayerKeyStateChange:

Код:

public OnPlayerKeyStateChange(playerid, newkeys, oldkeys)
{
if (PRESSED(KEY_FIRE))
line 1402  {
		if (IsPlayerInAnyVehicle(playerid))
		{
			AddVehicleComponent(GetPlayerVehicleID(playerid), 1010);
  }
	}
	return 1;

}

Help??

I'd use:

pawn Код:

if (newkeys & KEY_FIRE)
{
    if (IsPlayerInAnyVehicle(playerid))
    {
        AddVehicleComponent(GetPlayerVehicleID(playerid), 1010);
    }
}

This will set a new NOS everytime he/she presses KEY_FIRE

}

This will set a new NOS everytime he/she presses KEY_FIRE

And if i want to add more functions?
Like super jump?

Код:

if (newkeys & KEY_FIRE && oldkeys ~ KEY_FIRE )
{
    if (IsPlayerInAnyVehicle(playerid))
    {
        AddVehicleComponent(GetPlayerVehicleID(playerid), 1010);
    }
}

I suggest adding the second part of the if condition so that it won't try to add NOS every time a player presses a key while holding the fire key down.

Then just add a 'else' like this i guess:

pawn Код:

if (newkeys & KEY_FIRE)
{
    if (IsPlayerInAnyVehicle(playerid))
    {
        AddVehicleComponent(GetPlayerVehicleID(playerid), 1010);
    }
}
else if(newkeys & KEY_FIRE) // change, you get what i mean.
{


}

and so on.
