PotatoHotDog menawarkan API Gambar AI Gratis yang bisa Anda panggil langsung dari Streamer.bot, tanpa perlu middleware pihak ketiga. Panduan ini menunjukkan cara menambahkan skrip C# kustom kecil ke sub-aksi Eksekusi Kode pada Streamer.bot yang menghasilkan gambar AI dari prompt teks dan mengunduhnya ke disk.
Script ini hanya memerlukan kunci API PotatoHotDog Anda dan sebuah prompt yang menggambarkan gambar yang ingin Anda buat, dan script tersebut menyimpan gambar yang diunduh ke dalam folder khusus di dalam direktori instalasi Streamer.bot Anda.
Siapkan kunci API
Jika Anda belum memilikinya, buat kunci API dari dashboard Anda dan siapkan kunci API-nya. Anda akan membutuhkannya pada langkah berikutnya.
Ke Kunci API
Argumen Prasyarat
Untuk menghasilkan gambar AI, dua argumen perlu ditentukan di Streamer.bot sebelum sub action Execute Code dijalankan. Atau, dengan kata lain, kedua hal ini perlu ditentukan:
- Kunci API.
- Instruksi prompt yang menjelaskan gambar yang ingin Anda hasilkan.
Berikut adalah argumen Streamer.bot yang terkait:
- potatoKey
- potatoInstructions
Anda menentukan argumen dalam tindakan Anda dengan mengklik kanan pada Sub Actions, lalu memilih Add, Core, Arguments, dan akhirnya Set Argument.
Menambahkan Aksi Eksekusi Kode di Streamer.bot
Buka Streamer.bot dan pergi ke tab Aksi. Buat aksi baru, atau buka yang sudah ada, dan beri namanya yang akan kamu kenali nanti, seperti "PotatoHotDog AI Image".
Dengan aksi Anda dipilih, klik Tambah di bawah Sub Actions, lalu pilih Core, diikuti oleh Execute C# Code. Ini menambahkan sub action di mana Anda dapat menempelkan kode C# mentah yang dikompilasi dan dijalankan oleh Streamer.bot secara langsung.
Tempel skrip di bawah ini ke editor kode. Ini membaca argumen potatoKey dan potatoInstructions, memanggil API Generate AI Image kami untuk menghasilkan gambar dan mengambil URL-nya, dan kemudian mengunduh gambar yang dihasilkan ke dalam folder bernama temp_potatohotdog_images di dalam direktori instalasi Streamer.bot Anda.

Setelah menempelkan skrip, ingat untuk klik Find Refs dan Compile, dan pastikan itu berhasil dikompilasi. Simpan aksi tersebut, lalu jalankan secara manual atau hubungkan ke sebuah perintah atau hadiah poin saluran untuk menguji bahwa gambar tersebut dihasilkan dengan benar.
Periksa gambar yang diunduh
Setelah tindakan selesai dijalankan, Anda dapat memeriksa variabel Action melalui Riwayat Action untuk memastikan semuanya berjalan seperti yang diharapkan.
Di sana Anda akan menemukan jalur lokal tempat gambar yang dihasilkan disimpan di disk, di dalam folder temp_potatohotdog_images di direktori instalasi Streamer.bot Anda.
Buka folder itu untuk melihat gambar yang diunduh secara langsung.
Pemecahan masalah
Jika skrip tidak berjalan seperti yang diharapkan, cara terbaik untuk memecahkan masalahnya adalah dengan memeriksa log tindakan.
Anda bisa melakukannya dengan memeriksa variabel Action Anda melalui Action History.
