your problem you're trying cast sender player before check if sender player. sender console.
if want fix this, should check if sender player. if aren't should return false:
if(!(sender instanceof player)){ //the sender not player return false; } player player = (player) sender; //this can run safely, because //we know sender has //be player i recommend not putting code above of if statements. instead, should put above code inside each of statements, , handle if sender not player accordingly.
