如何写equals(==)函数?

Question

class Character {

construct new(name,life){
_name = name
_life = life
}

name  { _name }
life  { _life }
}

如果name和life相同，则应返回true，否则返回false。

Answer 1

class Character {

construct new(name,life){
_name = name
_life = life
}

name  { _name }
life  { _life }

==(other){
return _name == other.name && 
_life == other.life
}
}
var player_one = Character.new("Nova",100)
var player_two = Character.new("Mint Hot Chocolate",50)
var player_three = Character.new("Nova",100)
System.print(player_one == player_three) // Output: true
System.print(player_one == player_two) // Output: false
