Placeholders

Almost all placeholder are built around the concept of object, it's like a container.
For example a Player object contains property such as name, hp, x, y, z.
We references these properties with a . separator, for example: {player.name}, {player.hp}, {player.x}, {player.y}, {player.z}.

It can also be nested, for example:
member refers to a Guild Member in this instance.
Inside a guild member object will have a nickOrUsername property (Nickname, or username of the user if none).
Then there's also a user object that contains name, tag, id, avatarURL. It can be represented with json below:

"member": {
   "nickOrUsername": "My Nickname",
   "user": {
      "username": "LX86",
      "username": "@lx86",
      "id": "204071499135582208",
      "avatarURL": "https://link.to.avatar"
   }
}

We can reference them with {member.user.username}, {member.user.tag}, {member.user.id}, {member.user.avatarURL}.
