I'm coding a game with 100 tiles that are generated like this:
const allLetters = {
'A': { 'points': 1, 'tiles': 9 },
'B': { 'points': 3, 'tiles': 2 },
'C': { 'points': 3, 'tiles': 2 },
'D': { 'points': 2, 'tiles': 4 },
'E': { 'points': 1, 'tiles': 12 },
'F': { 'points': 4, 'tiles': 2 },
'G': { 'points': 2, 'tiles': 3 },
'H': { 'points': 4, 'tiles': 2 },
'I': { 'points': 1, 'tiles': 9 },
'J': { 'points': 8, 'tiles': 1 },
'K': { 'points': 5, 'tiles': 1 },
'L': { 'points': 1, 'tiles': 4 },
'M': { 'points': 3, 'tiles': 2 },
'N': { 'points': 1, 'tiles': 6 },
'O': { 'points': 1, 'tiles': 8 },
'P': { 'points': 3, 'tiles': 2 },
'Q': { 'points': 10, 'tiles': 1 },
'R': { 'points': 1, 'tiles': 6 },
'S': { 'points': 1, 'tiles': 4 },
'T': { 'points': 1, 'tiles': 6 },
'U': { 'points': 1, 'tiles': 4 },
'V': { 'points': 4, 'tiles': 2 },
'W': { 'points': 4, 'tiles': 2 },
'X': { 'points': 8, 'tiles': 1 },
'Y': { 'points': 4, 'tiles': 2 },
'Z': { 'points': 10, 'tiles': 1 },
' ': { 'tiles': 2 }
}
let tiles = [];
Object.keys(allLetters).forEach(letter => {
for (let i = 0; i < allLetters[letter]['tiles']; i += 1){
tiles.push(letter);
}
});
console.log(tiles);I want to associate each tile with a point value, so this is what I tried:
var playersTiles = [];
for (let i = 0; i < 7; i++){
let tileIndex = Math.round(Math.random() * (tiles.length - 1));
playersTiles.push(tiles[tileIndex]);
let letter = playersTiles[i];
let points = allLetters[letter]['points'];
playersTiles.push(tiles[tileIndex][points]);
tiles.splice(tileIndex, 1);
}
My code returns an error on this line:
let points = allLetters[letter]['points'];
It says:
allLetters[letter] is undefined
What am I doing wrong?
That's because tiles is a one dimensional array shown in your code here
let tiles = [];
Object.keys(allLetters).forEach(letter => {
for (let i = 0; i < allLetters[letter]['tiles']; i += 1){
tiles.push(letter); // Pushing only the letter which makes it one-dimensional array
}
});
And in this part playersTiles.push(tiles[tileIndex][points]); you are assuming that tiles is a two-dimensional array
