Hi, i want to ask what is this u.* in your code? examples from your code:
if (u.ins == null){
u.initUtils(this);
//or
if (selectedGoblin == null || selectedGoblin.getHealth() == 0 ||
u.isAttackedByOtherPlayer(selectedGoblin) || !selectedGoblin.exists())
//or
u.antiBan();
Its just im learning stuff from open sources and i got confused what is this u.* used everywhere.
