Usage

Add the OpenAi node

Setting up the API Key

Before using the plugin, make sure to set your OpenAI API key:

var openai = get_node("OpenAI")
openai.set_api("your-api-key-here")

Using ChatGPT

To send a prompt to ChatGPT:

var messages = [Message.new()]
messages[0].set_content("Hello, how are you?")
openai.prompt_gpt(messages)

Listen for the response:

func _ready():
	open_ai.connect("gpt_response_completed", gpt_response_completed)

func _on_gpt_response(message: Message, response: Dictionary):
	print(message.get_content())

Full code:

extends Node2D

@onready var open_ai = $OpenAi

# Called when the node enters the scene tree for the first time.
func _ready():
	##Conecting the output from chatgpt
	open_ai.connect("gpt_response_completed", gpt_response_completed)
	
	##Creating meessages template
	var messages:Array[Message] = [Message.new()]
	messages[0].set_content("say hi!")
	
	##setting the api key
	open_ai.set_api("")
	
	##Prompt chatgpt
	open_ai.prompt_gpt(messages)
	
func gpt_response_completed(message:Message, response:Dictionary):
	printt(message.get_as_dict())

Using DALL-E

To generate an image with DALL-E:

openai.prompt_dalle("A beautiful sunset over mountains")

Listen for the response:

func _ready():
	open_ai.connect("dalle_response_completed", dalle_response_completed)

func _on_dalle_response(texture: ImageTexture):
	$Sprite2D.texture = texture
