Someone please tell me what I'm missing here. When I click start game nothing happens and when I check the console I see "Game.js:34 Uncaught TypeError: Cannot read properties of undefined (reading 'activeToken')" but I've copied line by line code in the videos...
... class Game { constructor() { this.board = new Board(); this.players = this.createPlayers(); this.ready = false; }
/**
* Returns active player.
* @return {Object} player - The active player.
*/
get activePlayer() {
return this.players.find(player => player.active);
}
/**
* Creates two player objects
* @return {array} An array of two player objects.
*/
createPlayers() {
const players = [new Player('Player 1', 1, '#e15258', true),
new Player('Player 2', 2, '#e59a13')];
return players;
}
/**
* Initializes game.
*/
startGame(){
this.board.drawHTMLBoard();
this.activePlayer.activeToken.drawHTMLToken();
this.ready = true;
}
}

None of the js files could be found because the HTML was trying to load them from a "js" folder, and they were all currently stored in the top level folder. So I made a "js" folder and moved them all into it, and then the "Game.js" file couldn't be found because the file was named "game.js" (lower-case "g"). But after changing the file name I got your original error.
The reason the "activePlayer" getter in game is returning undefined is because it searches the players array for one that has an "active" property set to true, but as currently defined the "Player" class has no "active" property or getter method.

231,198 PointsIf you create a new workspace and upload the project files into it, you can then make a snapshot and share the link to it.
But do try running it first in the workspace, to be sure it still has the same issue.

231,198 PointsThe cause of the issue might be in a different part of the code, and this is why it's always a good idea to share the entire project. You might want to take a look at this video about sharing a snapshot of your workspace.
