How to make use of Grand Larceny vehicles

[TUTORIAL]

-------------------------------------------------------------------------------------------------------------------------------------

Hello people! How are you? This is my first ever tutorial, don't be so hard on me!

I noticed no one has made a tutorial on how to actually properly load and make use of the vehicles in the default Grand Larceny game mode.

This is a simple tutorial to show you how!

-------------------------------------------------------------------------------------------------------------------------------------

Step 1:

Go to your pawno/include folder and copy any .inc file. Paste it and it should show filename - copy.inc. Now, open that file and delete everything inside it.

Why? Because later on, I will provide a stock. LoadStaticVehiclesFromFile something used in the Grand Larceny game mode. The stock which I provided above makes LoadStaticVehiclesFromFile usable outside of Grand Larceny.

Step 2:

Rename the file to loadvehicles and replace the contents with this:

PHP Code:



stock LoadStaticVehiclesFromFile(const filename[])

{

    new File:file_ptr;

    new line[256];

    new var_from_line[64];

    new vehicletype;

    new Float:vSpawnX;

    new Float:vSpawnY;

    new Float:vSpawnZ;

    new Float:SpawnRot;

    new Color1, Color2;

    new index;

    new vehicles_loaded;


    file_ptr = fopen(filename,filemode:io_read);

    if(!file_ptr) return 0;


    vehicles_loaded = 0;


    while(fread(file_ptr,line,256) > 0)

    {

        index = 0;


        // Read type

          index = token_by_delim(line,var_from_line,',',index);

          if(index == (-1)) continue;

          vehicletype = strval(var_from_line);

           if(vehicletype < 400 || vehicletype > 611) continue;


          // Read X, Y, Z, Rotation

          index = token_by_delim(line,var_from_line,',',index+1);

          if(index == (-1)) continue;

          vSpawnX = floatstr(var_from_line);


          index = token_by_delim(line,var_from_line,',',index+1);

          if(index == (-1)) continue;

          vSpawnY = floatstr(var_from_line);


          index = token_by_delim(line,var_from_line,',',index+1);

          if(index == (-1)) continue;

          vSpawnZ = floatstr(var_from_line);


          index = token_by_delim(line,var_from_line,',',index+1);

          if(index == (-1)) continue;

          SpawnRot = floatstr(var_from_line);


          // Read Color1, Color2

          index = token_by_delim(line,var_from_line,',',index+1);

          if(index == (-1)) continue;

          Color1 = strval(var_from_line);


          index = token_by_delim(line,var_from_line,';',index+1);

          Color2 = strval(var_from_line);


          AddStaticVehicleEx(vehicletype,vSpawnX,vSpawnY,vSpawnZ,SpawnRot,Color1,Color2,180); // respawn 3 minutes

        vehicles_loaded++;

    }


    fclose(file_ptr);

    printf("Loaded %d vehicles from: %s",vehicles_loaded,filename);

    return vehicles_loaded;

}


stock token_by_delim(const string[], return_str[], delim, start_index)

{

    new x=0;

    while(string[start_index] != EOS && string[start_index] != delim) {

        return_str[x] = string[start_index];

        x++;

        start_index++;

    }

    return_str[x] = EOS;

    if(string[start_index] == EOS) start_index = (-1);

    return start_index;

}

Step 3:

Go to your game mode and add this:

PHP Code:



#include <loadvehicles>

Step 4:

Under OnGameModeInit, add LoadStaticVehiclesFromFile("vehicles/file.txt");
I will show all possible vehicle loads below.

Step 5:

Start your server!

-------------------------------------------------------------------------------------------------------------------------------------

There are 19 possible LoadStaticVehicle files

You can tell what the vehicles will be loaded with the file names.

PHP Code:



//Possible Vehicle Loads

LoadStaticVehiclesFromFile("vehicles/bone.txt");

LoadStaticVehiclesFromFile("vehicles/flint.txt");

LoadStaticVehiclesFromFile("vehicles/ls_airport.txt");

LoadStaticVehiclesFromFile("vehicles/ls_gen_inner.txt");

LoadStaticVehiclesFromFile("vehicles/ls_gen_outer.txt");

LoadStaticVehiclesFromFile("vehicles/ls_law.txt");

LoadStaticVehiclesFromFile("vehicles/lv_airport.txt");

LoadStaticVehiclesFromFile("vehicles/lv_gen.txt");

LoadStaticVehiclesFromFile("vehicles/lv_law.txt");

LoadStaticVehiclesFromFile("vehicles/pilots.txt");

LoadStaticVehiclesFromFile("vehicles/red_county.txt");

LoadStaticVehiclesFromFile("vehicles/sf_airport.txt");

LoadStaticVehiclesFromFile("vehicles/sf_gen.txt");

LoadStaticVehiclesFromFile("vehicles/sf_law.txt");

LoadStaticVehiclesFromFile("vehicles/sf_train.txt");

LoadStaticVehiclesFromFile("vehicles/tierra.txt");

LoadStaticVehiclesFromFile("vehicles/trains.txt");

LoadStaticVehiclesFromFile("vehicles/trains_platform.txt");

LoadStaticVehiclesFromFile("vehicles/whetstone.txt");

-------------------------------------------------------------------------------------------------------------------------------------

That is pretty much how simple it is! Have fun!

never mind ignore this

It's not bad, but in the future, it would help to explain what some of the things do (like what's going on in the LoadStaticVehiclesFromFile function) to avoid more confusion.

LoadStaticVehiclesFromFile something used in the Grand Larceny game mode. The stock which I provided above makes LoadStaticVehiclesFromFile usable outside of Grand Larceny.

Thank you Sreyas for your encouragement!

Not bad for your first time.
Good job.

Such explanations should be in the tutorial, not somewhere hidden in the replies.

"[...] Replace this [...] Add this [...] Copy this [...]" it's just instruction after instruction without making the reasoning clear to the reader. This is a forum for developers and most developers would also like to know WHY you use the code that you use and what it exactly does. Of course, more experienced developers can derive that from reading the code, but I don't see any of them reading this kind of tutorials.

I don't want to discourage you. Your will to contribute to the community is greatly appreciated!

UPDATE: Edited the post and added explanations to assist scripters in understanding what they are doing.

It's a function not a "stock".

^I didn't know about that! Thanks for the heads up!

Lmao no problem, I share the link in every thread where people call functions stocks.

The tutorial is OK as it's your first tutorial. :P

This is a very outdated function.

I've re-written the function to work with sscanf.

Code:

LoadStaticVehiclesFromFile(const filename[])
{
    static
        line[145],

        model,
        Float: x,
        Float: y,
        Float: z,
        Float: r,

        color1,
        color2,

        len,
        count = 0
    ;

    new
        File: handle = fopen(filename, io_read);
    if (!handle)
        return 0;

    while ((len = fread(handle, line)))
    {
        line[len-2] = 0;
        print(line);
        if (sscanf(line, "P<(),>{s[17]}iffffii", model, x, y, z, r, color1, color2))
            continue;
        if (!(399 < model < 612))
            continue;

        AddStaticVehicleEx(model, x, y, z, r, color1, color2, 180); // Respawns in 3 minutes (180 seconds)
        count++;
    }
    fclose(handle);
    
    printf("Loaded %i vehicles from: %s", count, filename);
    return count;
}
