Sizeof 2D array - CalvinC - 19.03.2016

I'm trying to loop through vehicles of the players job and unlocking them, so they're only locked for people without that job, right now i'm doing this:

Код:

// Garbage Truck Driver

JobVehicle[1][0] = AddStaticVehicleEx(408, 2182.3635, -1992.1925, 14.1022, 359.7592, 1, 1, 180000); // Trashmaster
JobVehicle[1][1] = AddStaticVehicleEx(408, 2187.0657, -1993.5066, 14.0923, 359.9882, 1, 1, 180000); // Trashmaster
JobVehicle[1][2] = AddStaticVehicleEx(408, 2192.1223, -1994.7883, 14.0956, 0.0472, 1, 1, 180000); // Trashmaster
JobVehicle[1][3] = AddStaticVehicleEx(408, 2165.1445, -1972.4277, 14.1021, 179.3826, 1, 1, 180000); // Trashmaster

// Delivery Driver

JobVehicle[2][0] = AddStaticVehicleEx(499, 2486.5935, -2115.5938, 13.5393, 359.8707, 1, 1, 180000); // Benson
JobVehicle[2][1] = AddStaticVehicleEx(499, 2481.7615, -2115.6641, 13.5385, 356.5260, 1, 1, 180000); // Benson
JobVehicle[2][2] = AddStaticVehicleEx(456, 2476.6794, -2114.4895, 13.7211, 1.6723, 1, 1, 180000); // Yankee

Код:

for(new v = 0; v < sizeof(JobVehicle[PlayerInfo[playerid][Job]]); v ++)
{
    if(IsValidVehicle(v)) SetVehicleParamsForPlayer(v, playerid, 0, 0);
}

But the loop gives errors:

Quote:

(2731) : error 001: expected token: "]", but found "-integer value-"
(2731) : error 029: invalid expression, assumed zero
(2731) : error 029: invalid expression, assumed zero
(2731) : fatal error 107: too many error messages on one line

So what is the proper way of doing this?

for(new v = 0; v < sizeof(JobVehicle[PlayerInfo[playerid][Job]]))

Re: Sizeof 2D array - introzen - 19.03.2016

Try this:

pawn Код:

for(new v=0; v <= sizeof(JobVehicle[PlayerInfo[playerid][pJob]]) v++) {
    if(IsValidVehicle(v)) SetVehicleParamsForPlayer(v, playerid, 0 0);
}

You forgot to to create the actual loop by adding "v++" to it. I also added "<=" as the first vehicle in the array else wouldn't be affected by the loop (if i'm not mistaken. Was a long time ago I did programming).

Sorry i forgot to include that in the post, edited.
Still the same errors.

An array only has one size which is determined at compile time. Therefore you can't use an index. Indices that aren't explicitly assigned a value are implicitly initialized to 0. You can use:

PHP код:



sizeof(JobVehicle)

PHP код:



sizeof(JobVehicle[])

To get the size of the first and second dimension, respectively.

According to this information (which I didn't know appearently, thank you btw) would this work perhaps?

for(new v=0; v <= sizeof(JobVehicle[]) v++) {
    if(IsValidVehicle(v) && JobVehicle[] == PlayerInfo[playerid][pJob]) SetVehicleParamsForPlayer(v, playerid, 0 0);
}

Re: Sizeof 2D array - Vince - 19.03.2016

You can use indices inside the loop, just not in combination with the sizeof operator itself. Which means what is likely desired is:

PHP код:



for(new v = 0; v < sizeof(JobVehicle[]); v++) {

    SetVehicleParamsForPlayer(JobVehicle[PlayerInfo[playerid][pJob]][v], playerid, 0, 0);

}

Assuming that 0 <= PlayerInfo[playerid][pJob] < sizeof JobVehicle.
