[JPTRON]

Hello,

I'm trying to code my own KillReward plugin and I want to register the user points inside individuals .txt files.

#pragma semicolon 1

#define DEBUG

#define PLUGIN_AUTHOR "JPTRON"
#define PLUGIN_VERSION "1.00"

#include <sourcemod>
#include <sdktools>
#include <files>
#include <string>

#pragma newdecls required

public Plugin myinfo = 
{
	name = "KillReward",
	author = PLUGIN_AUTHOR,
	description = "Receive points when killing someone.",
	version = PLUGIN_VERSION,
	url = ""
};

public void OnPluginStart()
{
	HookEvent("player_death", Event_PlayerDeath);
}


public Action Event_PlayerDeath(Event event, const char[] name, bool dontBroadcast) {

    int victim = event.GetInt("userid");
    int attacker = event.GetInt("attacker");
    char str[40], attackerStr[40];
    
	 IntToString(attacker, attackerStr, sizeof(attackerStr));
	Format(str, sizeof(str), "/players/%s.txt", attackerStr);

    
    if(victim == attacker || attacker == 0){	
  		return;
  	}


	Handle attackerFile = OpenFile(str, "r+");
    
  	if(!attackerFile){
  		WriteFileLine(attackerFile, "10");
 	}
  
    CloseHandle(attackerFile);     
    
    attackerFile = OpenFile(str, "w+");
    
    int attackerPoints;
    
    attackerPoints = ReadFileLine(attackerFile, attackerStr, sizeof(attackerStr));
    
    attackerPoints += 10;
    
    IntToString(attackerPoints, attackerStr, sizeof(attackerStr));
    
    WriteFileLine(attackerFile, attackerStr);
    
    CloseHandle(attackerFile); 
    
}
