The numbers that make the game
At the top of the code are the settings — change one, run the game, and feel the difference.
This is how game designers balance a game.
let shipSpeed = 320 | |
let laserSpeed = 600 | |
let alienSpeed = 120 | |
let alienEvery = 1.2 | A new alien every … seconds |
let alienPoints = 10 | |
let alienShootsEvery = 2 | An alien fires at you every … seconds |
let startLives = 3 | |

Harder: make the aliens faster.मुश्किल: aliens को तेज़ करें।
-
Each alien is worth more points.हर alien के अंक बढ़ाएँ।
-
Win at 100 points: after score.add(...), check the score.100 अंक पर जीत: score.add(...) के बाद स्कोर जाँचें।
if (score.value >= 100) {
tj.victory("You saved the planet!")
}
-
Add a timer.एक timer जोड़ें।
tj.timer(60, () => tj.victory("You survived!"))
