I have an object that looks something like this:

const state = []

const spells = [
  {
    name: 'test',
    channelDuration: 1000,
    castDuration: 1000,
    cast: () => {
     state.push(THIS) // <--
    }
  }, {...}, {...}
]

When a player uses a spell, that spell gets stored into the game state and then waits for the channelDuration and castDuration to pass.

Once able to cast, it looks into the state and calls the cast method:

State.quest.bossFightState[USER].spell.cast()

state = [Spell]

On said cast, i need to push the spell into the a new array called statuses. However, i can’t reference the object within the cast method without using some additional helper functions to grab the specific spell. And I dont want to pass add a parameter spell into the cast method because that just seems dumb.

Any ideas? Or is a helper method the way to go here.

>Solution :

I’m surprised nobody else caught this… You’re using this inside of an arrow function. The this keyword acts differently in arrow functions – read more about that here

const state = [];

const spells = [
    {
        name: 'test',
        cast: function () {
            state.push(this);
        },
    },
];

spells[0].cast();
console.log(state);
