Hello Kenny. I greatly appreciate this series, and I have been practicing game dev everyday this month, thanks to your work.

And I hope you make a tutorial on how to build Tetris! I have encountered difficult problems AFTER implementing rotation of pieces, and am curious how you would handle the pieces from the start.

Hey bro. Nice work. Keep it up!
I have a doubt, don't know if you're gonna be willing to answer it, if not, i understand. Without further ado

i wrote basically the same code as you until the minute 8:40 of the video, but in the console, when it prints the array "cardSet" two times, it's printing the array with the cards randomly disposed both of the times. Even with the first "console.log" being written before the shuffle structure (for). If i commentate the 'for' loop, it does show the array in the order that was supposed to.

here is the code (so there's no doubt, that is the same):

var errors = 0
var cardList = [
"darkness",
"double",
"fairy",
"fighting",
"fire",
"grass",
"lightning",
"metal",
"psychic",
"water"
]

var cardSet
var board = []

window.onload = function(){
shuffleCards()
startGame()
}

function shuffleCards(){
cardSet = cardList.concat(cardList)
console.log(cardSetl)

for(let i = 0; i < cardSet.length; i++){
let j = Math.floor(Math.random() *cardSet.length)

let temp = cardSet[i]
cardSet[i] = cardSet[j]
cardSet[j] = temp
}
console.log(cadSetl)
}

function startGame(){

}

hi, when you made the game you used the shuffling algorithm. where did you learn it? what book should I read to learn more about these algorithms? Or what video to watch?

Can you please code a text based space exploration game in html, css and script? I tried to generate the codes from Chatgpt4 and it did to same extent.
