Array in an array - MP2 - 19.02.2011

I need to store multiple sets of coordinates in a single array for multiple races, what's the best way to do this?

Re: Array in an array - Hiddos - 19.02.2011

I'd do it like this:

pawn Код:

new Float:RaceCoords[ MAX_RACES ][4]; //X - Y - Z - Rotation Angle

Respuesta: Array in an array - anonymousx - 19.02.2011

Yeah, Hiddos is right.
Do somethind like this:

pawn Код:

#define MAX_RACES 5 //define the max races.
new Float:RaceCorrds[MAX_RACES][4] = {
   {X,Y,Z,A},
   {X,Y,Z,A},
   //...
   {X,Y,Z,A}
};

Re: Array in an array - MP2 - 19.02.2011

I have 8 coordinates per race.

AW: Array in an array - Nero_3D - 20.02.2011

pawn Код:

stock const Float: RaceCoords[][] = {
   {1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0},
   {1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0},
   //...
   {1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0}
};

Done ? You can use so much numbers how you want if you didnt used any index in the header

Although 8 coords is a strange number in my opinion :S

He probably means checkpoints per race. lolz

Peace...

Re: Array in an array - MP2 - 20.02.2011

I have 8 spawnpoints per race. Anyway i've sorted that bit out, now I need an array to store any number of variables for each race. This is for the vehicles to be used in that race. Example:

Race 1 uses Infernus and Sultan
Race 2 uses Infernus, Sultan and Turismo
Race 3 uses Quad and Sanchez

I need to store that in an array.

pawn Код:

new race_vehicle_list[3][] = {
{411, 560},
{411, 560, 451},
{471, 468}
};

Should that work?

Re: Array in an array - MP2 - 20.02.2011

pawn Код:

if(dialogid == DIALOG_RACE && response) // Start race
    {
        format(string, sizeof(string), "%s", VehicleNames2[race_vehicle_list[listitem][0]-400]);
        for(new i=1; i<sizeof(race_vehicle_list[listitem]); i++)
        {
            format(string, sizeof(string), "%s\n%s", string, VehicleNames2[race_vehicle_list[listitem][i]-400]);
        }
        ShowPlayerDialog(playerid, DIALOG_RACE_VEHICLE, DIALOG_STYLE_LIST, "Start Race - Select Vehicle", string, "Race", "Cancel");
        SetPVarInt(playerid, "race_map", listitem+1);
        return 1;
    }

Gives these errors:

4 Errors.

That line is:

pawn Код:

for(new i=1; i<sizeof(race_vehicle_list[listitem]); i++)

and it's refering to the sizeof(race_veh...) part. How can I tell how many vehicles are in the array?

This is the array:

pawn Код:

new race_vehicle_list[][] = {
{411, 411, 411},
{411, 522, 522},
{520, 520}
};

I think that will solve your problem:

pawn Код:

if(dialogid == DIALOG_RACE && response) // Start race
    {
        format(string, sizeof(string), "%s", VehicleNames2[race_vehicle_list[listitem][0]-400]);
        for(new i=1; i <= 15; i++)//Change 15 for the MAX Races coordinates
        {
            format(string, sizeof(string), "%s\n%s", string, VehicleNames2[race_vehicle_list[listitem][i]-400]);
        }
        ShowPlayerDialog(playerid, DIALOG_RACE_VEHICLE, DIALOG_STYLE_LIST, "Start Race - Select Vehicle", string, "Race", "Cancel");
        SetPVarInt(playerid, "race_map", listitem+1);
        return 1;
    }

I hope that i have helped
