Bagaimana untuk menggunakan uniapp untuk membangunkan permainan ular? Artikel berikut akan membimbing anda langkah demi langkah dalam melaksanakan permainan Snake dalam uniapp. Saya harap ia akan membantu anda!
Kali pertama saya bermain Snake, saya masih samar-samar ingat ia adalah permainan pertama yang ayah saya mainkan untuk saya selepas ?️
Permainan mini ini menggunakan uniappPembangunan
Saya tidak akan menerangkan butiran mengenai butiran bahagian hadapan, sila baca secara terperinci: https://juejin.cn/post/7085727363547283469#heading-14

Struktur kod
Jika perlu, sila pergi ke github untuk melihat struktur kod terperinciBeri ular kami kotnya
Rendering badan ular adalah berdasarkan
(dengan badan ular di dalam) untuk memadankan indeks panel lantai untuk mencari grid yang sepadan dan mengubah suai imej latar belakang untuk menjadikan badan ular, kepala dan ekor ular, iaitu untuk mengambil digit ke-0 dan terakhir
Dan cari grid yang sepadan untuk mengubah suai imej latar belakang semasa

Tambah kesan bunyi pada ular tamak
Menambah kesan bunyi permainan akan menjadikan permainan lebih mengasyikkan Sekarang kita perlu menambahkan muzik latar pada ular, klik muzik interaktif, muzik untuk ular kentut, muzik untuk ular makan makanan, dan undur untuk muzik letupan serangga
Mula-mula tambah muzik latar, sentiasa ada orang jahat yang boleh bermain sehingga peta penuh

untuk mendapatkan laluan muzik dan menyediakan main balik automatik
Muzik latar belakang berdering dan ia terus berdering selepas permainan berakhir. Saya keliru apabila mendengarnya. Tidak sabar, kami menjeda muzik latar selepas permainan ular
Muzik dijeda dan ia tidak akan jelas
Muzik pertama berjaya ditambahkan dan rehat adalah lebih mudah. Kira detik letupan pepijat juga perlu meletup atau Selepas permainan selesai, anda perlu mengosongkan kesan bunyi undur uni.createInnerAudioContext (main balik seterusnya akan bermula dari awal lagi kesan bunyi dan main balik gelung tidak). diperlukan. Kod yang selebihnya dilampirkan di bawah innerAudioContext
