Hello, i wanted to make my first tutorial about creating a gangzone manually and saving it in a txt file, Let's start:
Needed includes:
Got them? good , let's switch to next step, We're going to make some player variables to be able to save the Min's and Max's with them , But before let's explain what are gang zones, how are they coordinates, how they can be used,
A gang zone is a squared place, Used to be in the radar / map, It can be an oblong, That's depends on it's coordinates set, we have 4 coordinates here, Includes X Y for both, We will not use Z coordinate be cause the radar is set a 2D Coordinate system, So we're gonna get just X & Y, X(right - left) Y(forward - backward),
In the GTA SA world, X coordinate's value increases when we go right, Y coordinate's value increases when we go forward ,
Both used to be a float,
Got it? Now let's explain the min and max:
Min = Minimum
Max = Maximum
with creating a gang zone, we're gonna use Min to set the Minimum coordinate of X and Y , With max we're gonna set the max coordinate of the X, Y
A paint shows you it better:
As paint says, both coordinates result their Min point and Max point to create the gangzone.
Let's now start scripting:
We made the player's variables for the points, we'll use your friend's pos to get the max point
Let's start explaining line by line!
id = id of the player to use him to get the Max point.
zvar = zone's variable name like( new lol = Gangzonecreate etc..)
*We used sscanf to check the parameters after the command text, so we check if he missed some parameter, we'll send him an error message
*We checked if id is not connected or invalid, we'll send the playerid an error message.
*Here we got playerid pos( playerid = Min point) and (id = Max point) , you're gonna ask why we used the Z, be cause we can't leave the Z in getplayerpos code or it will give us a compiling error. but we'll get the x and y only without the Z.
* We checked if the Min X and Y is more than Max X and Max Y, so that will return a bug, so we made that if the Min is more than Max will return an error message, be cause the Max should always be more than Min.
*here we opened a new file called "szones" savedzones, we used the variable 'zones' to define the file in the script.
* here we checked if the file exists in the scriptfiles folder, else it will not save it in any place and will cause a bug.
*Here we created a string with 128 cells and formated it with a code "Gangzonecreate" to save it in the file with info, %f used to define floats in script, %s used for strings.
* and here we used fwrite to write the code inside the file then we closed the file.
*finally we added an error message if the file is not exist.
P.S: X2 & Y2 used to be the max point and X and Y used to be the Min.
To be known:
- It will not create the zone while u are in the game, it will save it in the file and you are gonna copy the code and paste it into your script
- You can use Y_INI for fast saving and loading, i used file functions to increase your knowledge of normal saving.

Needed includes:
pawn Code:
#include <a_samp> // Offical one
#include <zcmd> // for easy command writing
