I am attempting to write a dealer function for a card game, I want the function to keep its i value each time its called, so that that the card pile( player1Deck and player2Deck) gets smaller and smaller till empty. currently the i value looks like it will reset each time the function is called how can I stop this.
I am very new to all of this.
function dealOut(){
for (let i = 0; i < player1DeckHandcells.length; i++) {
const cell = player1DeckHandcells[i];
cell.appendChild(player1Deck.cards[i].getHTML)
}
for (let i = 0; i < player2DeckHandcells.length; i++) {
const cell = player2DeckHandcells[i];
cell.appendChild(player2Deck.cards[i].getHTML)
}
}
More information
Each dealout call should make i increase by 7. this means we are on the 8th "card"(player1Deck.cards[i].getHTML and player2Deck.cards[i].getHTML) in the "deck"( player1Deck and player2Deck)and there should be a total of 28 cards with 21 left to go. I want the i value to count through these "cards", so it doesn't just repeat the first 7 every time dealout is called.
You can use a closure (a function that keeps a copy of the outer variables). We can use that function for dealOut. Note: arrays are zero-indexed so i starts at 0 not 1.
function loop() {
// Maintain a count
let count = 0;
// Return a function that we actually use
// when we call dealOut. This carries a copy
// of count with it when it's returned that we
// can update
return function () {
const arr = [];
// Set i to count, and increase until
// i ia count + 7
for (let i = count; i < count + 7; i++) {
arr.push(i);
}
console.log(arr.join(' '));
// Finally increase count by 7
count += 7;
}
}
const dealOut = loop();
dealOut();
dealOut();
dealOut();
dealOut();
