PotatoHotDog ponuja brezplačen API Generate AI Images, ki ga lahko pokličete neposredno iz Streamer.bot, brez potrebe po kakršnem koli posredniku tretje osebe. Ta vodič vam pokaže, kako dodate majhno prilagojeno C# skripto v Streamer.bot Execute Code podakcijo, ki iz tekstovnega poziva generira AI sliko in jo shrani na disk.
Skript potrebuje le vaš PotatoHotDog API ključ in navodilo, ki opisuje sliko, ki jo želite ustvariti, ter shrani preneseno sliko v namensko mapo znotraj imenika za namestitev Streamer.bot.
Pripravi API ključ
Če ga še nimate, na nadzorni plošči ustvarite API ključ in ga imejte pri roki; v naslednjem koraku ga boste potrebovali.
Pojdi na API ključe
Predpogojni Argumenti
Da bi generirali AI sliko, je treba pred izvedbo podakcije Execute Code v Streamer.bot določiti dva argumenta. Oziroma, drugače povedano, je treba določiti te dve stvari:
- API ključ.
- Navodila v promptu, ki opisujejo sliko, ki jo želite ustvariti.
Ti se nanašajo na naslednje argumente Streamer.bot:
- potatoKey
- potatoInstructions
Določite argumente v vaši akciji z desnim klikom na Podakcije, nato izberite Dodaj, Jedro, Argumenti in na koncu Nastavi argument.
Dodajanje akcije Izvedi kodo v Streamer.bot
Odprite Streamer.bot in pojdite na zavihek Akcije. Ustvarite novo akcijo ali odprite obstoječo in ji dodelite ime, ki ga boste pozneje prepoznali, na primer "PotatoHotDog AI Image".
Ko imate izbrano dejanje, kliknite Dodaj pod Podakcije, nato izberite Core, nato Execute C# Code. To doda poddejanje, v katerem lahko prilepite surovo kodo C#, ki jo Streamer.bot prevede in zažene takoj.
Prilepite spodnjo skripto v urejevalnik kode. Prebere argumenta potatoKey in potatoInstructions, pokliče naš Generate AI Image API, da ustvari sliko in pridobi njen URL, nato prenese dobljeno sliko v mapo z imenom temp_potatohotdog_images znotraj vašega namestitvenega direktorija Streamer.bot.

Po prilepljanju skripte se prepričajte, da kliknete Find Refs in Compile in da se uspešno kompilira. Shrani dejanje, nato ga sprožite ročno ali ga povežite z ukazom ali nagrado kanalnih točk, da preverite, ali je slika pravilno generirana.
Preveri preneseno sliko
Ko se akcija izvede, lahko preko Zgodovine akcij preverite akcijske spremenljivke, da potrdite, da je vse delovalo, kot je bilo pričakovano.
Tam boste našli lokalno pot, na kateri je bila generirana slika shranjena na disku, znotraj mape temp_potatohotdog_images v vašem imeniku namestitve Streamer.bot.
Odprite tisto mapo, da boste neposredno videli preneseno sliko.
Odpravljanje težav
Če skripta ne deluje, kot je pričakovano, je najboljši način za odpravljanje napak preverjanje zapisnikov dejanj.
To lahko storite tako, da preverite svoje spremenljivke akcije preko Zgodovine dejanj.
