Issue with joining player to class, using DBNPC functions.

Issue: After joining a player to a class, calling functions defined in the class only works within a with statement. Trying to execute them by other means causes the class itself to never be invoked. Example given:

I'm not sure what is causing this behavior in which class calls work fine inside of a with statement, but do not work outside of it.

PHP Code:


		
			
with(findplayer("Mark Sir Link")){
  addhat3(922);  //successfully manipulates SQL row
  echo(hashat3(922)); //returns true
}
findplayer("Mark Sir Link").addhat3(921); //does not call class
echo(findplayer("Mark Sir Link").hashat3(921)); //returns false
}

class:

PHP Code:


		
			
function onCreated(){
  this.sqlcontrol = findnpc("SQL-Control");
}
function hashat3(temp.i){
  client.showhats = gethats3();
  return this.sqlcontrol.playerHasHat(player, i);
}

function addhat3(temp.i){
  this.sqlcontrol.playerAddHat(player, i);
  client.showhats = gethats3();
}

function removehat3(temp.i){
  this.sqlcontrol.playerRemoveHat(player, i);
  client.showhats = gethats3();
}

function gethats3(){
  return this.sqlcontrol.playerGetHats(player);
}

DB-NPC:

PHP Code:


		
			
public function playerHasHat(temp.pl, temp.i){
  return (i in playerGetHats(pl));
}

public function playerGetHats(temp.pl){
  temp.query = "SELECT censored FROM censored WHERE account='%s'";
  temp.ret = reqsql2("censored", format(query, pl.account), true);
  return ret[0].hats.tokenize(",");
}

public function playerRemoveHat(temp.pl, temp.i){
  temp.hats = playerGetHats(pl);
  temp.hats.remove(i);
  temp.query = "UPDATE censored SET censored='%2$s' WHERE account ='%1$s'";
  reqsql2("censored", format2(query, {pl.account, hats}), false);
  savelog2("hatdbSQL_log.txt","hat" @ i @ " removed from " @ pl.account);
}

public function playerAddHat(temp.pl, temp.i){
  temp.hats = playerGetHats(pl);
  temp.hats.add(i);
  temp.query = "UPDATE censored SET censored='%2$s' WHERE account ='%1$s'";
  reqsql2("censored", format2(query, {pl.account, hats}), false);
  savelog2("hatdbSQL_log.txt","hat" @ i @ " added to " @ pl.account);
}



function reqsql2(temp.db, temp.query, temp.waitfor){
  temp.req = requestsql2(db, query, waitfor);
  
  if(req.error != ""){
    echo(req.error, query);
  }
  
  if(!waitfor){
    return;
  }
  
  if(!req.completed){
    waitfor(req, "onReceiveData", 60);
  }
  return req.rows;
}

Seems somewhat similar to this issue:

PHP Code:


		
			
for (temp.pl: findlevel("somelevel.nw").players) {

  //does not work

  temp.pl.findweapon("myweapon").trigger("Event");



  //works

  with (temp.pl) {

    findweapon("myweapon").trigger("Event");

  }

}

Make the functions public in the class you join to the player.

  }

}

Try:

temp.pl.weapons[temp.pl.weapons.index((@"myweapon"))].trigger("Event");

I don't believe findweapon would be a player function. Then you could do something like this in a player-joined class:

PHP Code:


		
			
public function triggerWeapon(wep, a, b, c, d, e, f) {

  player.weapons[player.weapons.index((@wep))].trigger(a, b, c, d, e, f);

}

They actually had been before and I tried making them not public, figuring the player should have access to those either way if it is joined to it. Was not a working fix for the issue.

The player has access to them but you're not calling them from inside the player object.
