Solved Undefind index error!

My code is working but why i have this error when the code run:

Code:

[20:10:19] [Server thread/CRITICAL]: Could not pass event 'pocketmine\event\player\PlayerChatEvent' to 'KICKMS v1.0.0': Undefined index: on KICKMS\Main
[20:10:19] [Server thread/CRITICAL]: ErrorException: "Undefined index:" (EXCEPTION) in "KICKMS/src/KICKMS/Main" at line 772

This is 772 line:

PHP:

if($this->games[$this->getGameByPlayer($player)]["Status"] == "INGAME"){


 

we need more lol what is $this->games[],$this->getGameByPlayer

 

This is $this->games:

PHP:

public $games = ["Game1" => ["Arena" => "RM-1", "Status" => "JOINABLE"]];

And this is getGameByPlayer function:

PHP:

public function getGameByPlayer($player){
if(is_null($player)) return;
foreach($this->games as $game => $value){
if($value["Arena"] == $player->getLevel()->getFolderName()){
return $game;
}}}

 

PHP:

$this->games[$this->getGameByPlayer($player)]

Are you use that entry exists in $games? Note that game can be null/void in your getGameByPlayer() method, which equates to "" key.

The error happens when you try accessing an index of an empty.

PHP:

$x = [];
$x["INDEX"] === "SOMETHING";//Undefined index "INDEX"

$x["INDEX"] = [];
$x["INDEX"]["INDEX2"] === "SOMETHING";//Undefined index "INDEX2"


 

Thank you i made this function:

PHP:

public function inGame($player){
if($this->getGameByPlayer($player) == ""){
return false;
}else{
return true;
}}

and add it up of:

PHP:

if($this->games[$this->getGameByPlayer($player)]["Status"] == "INGAME"){

and became like this:

PHP:

if($this->inGame($player){
if($this->games[$this->getGameByPlayer($player)]["Status"] == "INGAME"){
//do something
}}

And it works, Solved!
