Tertabrak!

Termasuk bagian Dasar-Dasar Scripting Unity dalam perjalanan Unity di Coddy. Pelajaran 79 dari 85.

Tantangan

Sedang

Akhiri permainan saat sebuah balok menyentuh pelari.

Di dalam perulangan balok, setelah sebuah balok bergerak, baca posisinya sebagai Vector3 b.
Saat Mathf.Abs(b.x - transform.position.x) < 1f && Mathf.Abs(b.y - transform.position.y) < 1f, catat Game over, atur enabled = false; dan return;.

Tekan tombol “Main” dan biarkan sebuah balok mendarat di atasmu: Console menampilkan Game over dan semuanya berhenti. Lalu tekan tombol “Periksa”.
