Peningkatan Sistem Mendaki dari Set 2 dan Lainnya
Tambahkan node RayCast2D ke adegan pemain.
Seperti inilah karakter saya. Tambahkan RayCast ke awal panah.
Secara umum, saya akan menunjukkan semua kode karakter saya dan mencoba mengomentarinya sejelas mungkin.

Kesimpulan
Saat ini, ini adalah kode karakter paling mutakhir yang baru saja saya buat. Karena fakta bahwa kodenya sudah siap sepenuhnya, saya tidak punya apa-apa untuk ditambahkan secara terpisah. Dan karena saya mengambil pelajaran tentang jebakan dalam siklus terpisah, saya juga tidak mengatakan apa-apa tentang contoh penggunaan sistem interaksi. Saya juga bertanya-tanya apa yang ingin Anda ketahui di bagian selanjutnya dan disajikan di bawah survei yang terdiri dari ide-ide yang muncul di benak saya untuk mekanik. Terima kasih telah membaca dan sampai lain waktu.
