PotatoHotDog pakub tasuta Generate AI Images API-d, mida saad otse Streamer.botist kutsuda, ilma kolmanda osapoole vahendustarkvarata. See juhend näitab, kuidas lisada väike kohandatud C# skript Streamer.bot Execute Code sub action'i, mis genereerib AI-pildi tekstipäringust ja salvestab selle kettale.
Skript vajab ainult sinu PotatoHotDog API võtit ja kirjeldust pildist, mida soovid genereerida, ning see salvestab allalaaditud pildi eraldatud kausta sinu Streamer.bot installikataloogis.
Valmista API võti
Kui sul seda veel ei ole, loo API võti oma juhtpaneelilt ja hoia see valmis, vajad seda järgmiseks sammuks.

Eeltingimused Argumendid
AI-pildi genereerimiseks tuleb Streamer.botis enne Execute Code alamtoimingut kaks argumenti määrata. Teisisõnu tuleb määrata need kaks asja:
- API võti.
- Juhised, mis kirjeldavad pilti, mida soovid genereerida.
Need vastavad järgmistele Streamer.bot'i argumentidele:
- potatoKey
- potatoInstructions
Sa määrad oma toimingu argumendid, paremklõpsates alamtoimingute peal, seejärel vali Lisa, Põhi, Argumendid ja lõpuks Määra argument.
Koodi täitmise toimingu lisamine Streamer.botis
Avage Streamer.bot ja minge Toimingute vahekaardile. Looge uus toiming või avage juba olemasolev toiming ning andke sellele nime, mida hiljem ära tunnete, näiteks "PotatoHotDog AI Image".
Kui sinu toiming on valitud, klõpsa Lisa alamtoimingute all, seejärel vali Core ja seejärel Execute C# Code. See lisab alamtoimingu, kuhu saad kleepida puhast C# koodi, mida Streamer.bot kompileerib ja käivitab jooksvalt.
Kleepige allolev skript koodiredaktorisse. See loeb potatoKey ja potatoInstructions parameetrid, kutsub meie Generate AI Image API välja pildi genereerimiseks ja selle URL-i saamiseks, ning laadib seejärel valminud pildi alla kausta nimega temp_potatohotdog_images sinu Streamer.boti installikataloogi.

Pärast skripti kleepimist klikka 'Leia viited' ja 'Kompileeri' ning veendu, et see kompileerub edukalt. Salvesta toiming, seejärel käivita see käsitsi või ühenda see käsu või kanali punktide preemiaga, et testida, kas pilt genereeritakse õigesti.
Vaata allalaaditud pilti
Kui toiming on käivitunud, saate Action History kaudu kontrollida Action variables, et kinnitada, et kõik töötas ootuspäraselt.
Seal leiad kohaliku tee, kuhu genereeritud pilt salvestati kettale, asudes temp_potatohotdog_images kaustas sinu Streamer.bot paigalduskataloogis.
Ava see kaust, et vaadata allalaaditud pilti otse.
Tõrkeotsing
Kui skript ei käitu nii, nagu oodatud, on vea tuvastamiseks parim viis kontrollida tegevuste logisid.
Sa saad seda teha, uurides oma Action muutujad Action History kaudu.
