INVALID_PLAYER_ID Help +REP - Ahmed21 - 22.05.2017

Hello there,

I've made one simple IF statement on OnPlayerTakeDamage callback.

The if statement is supposed to check if the issuerid (Who made the damage) is valid.

PHP Code:



public OnPlayerTakeDamage(playerid, issuerid, Float: amount, weaponid, bodypart)

{

    if(issuerid != INVALID_PLAYER_ID) return 0; // If issuerid is valid ID then it returns 0;

    

     new string[128];

    format(string, sizeof(string), "Damager: %d || Damaged: %d || bodypart: %d", issuerid, playerid, bodypart);

    SCM(playerid, -1, string);

    return 1;

}

I've checked it many times, and I'm pretty sure that the code is correct.

Please, tell me what is the problem in this

if(issuerid != INVALID_PLAYER_ID) return 0; // If issuerid is valid ID then it returns 0;

if(issuerid == INVALID_PLAYER_ID) return 0; // If issuerid is valid ID then it returns 0;

You want to check if is valid, and if is return 0? Or to check is invalid to return 0?

I want to check if someone has damaged playerid, if someone damaged him then return 0. It sounds weird for some people but that's what I want to make.

I guess that should work :

PHP Code:



public OnPlayerTakeDamage(playerid, issuerid, Float: amount, weaponid, bodypart) 
{ 
    if(IsPlayerConnected(issuerid))
        return 0; // If issuerid is valid ID then it returns 0; 
     
    new string[128]; 
    format(string, sizeof(string), "Damager: %d || Damaged: %d || bodypart: %d", issuerid, playerid, bodypart); 
    SCM(playerid, -1, string); 
    return 1; 
}

{ 

    if(issuerid == INVALID_PLAYER_ID) return 0; // If issuerid is valid ID then it returns 0;

    return 1; 

}

if(issuerid == INVALID_PLAYER_ID) return 0;
This checks if issuerid is invalid, if yes, it returns 0. but in your code it returns 0 if the issuer's valid. so it'll return 0 mostly.
