Question
So i have a line here that connects to the Hugging Faces API “Gemma 7b” model. Im making a school project where the player types in a input for a given survival scenario and AI tells the player if they will survive and if not - why. Think of Death by AI from Discord. Everything works great..but...there was one small issue which is - basically the players input is sent to the API but it doesnt return a response. I gave the code to ChatGPT and now it is hell…On the output part it gives out the players input instead of the APIs plus on the part where it is written “comment:” it stays blank (This should be the API`s response…
Here are the codes:
class_name GameStart
extends Node2D
var scenarios = ["Venomous snake attacks you", "Lost in a forest", "Stuck in a snowstorm", "Caught in a rip current", "Encounter a wild bear", "Trapped in a burning building", "Stranded on a deserted island", "Caught in an earthquake", "Witness someone choking", "Caught in a flash flood", "Stuck in an elevator", "Facing a home invasion", "Bitten by a spider", "Falling through ice", "Stuck in quicksand", "Power outage during a storm", "Vehicle breaks down in the desert", "Trapped in a cave", "Lost at sea", "Facing a tornado", "Attacked by a dog", "Poisoned by a plant", "Caught in a landslide", "Encounter a mountain lion", "Caught in a volcanic eruption", "Stranded in a swamp", "Witness a car accident", "Bitten by a tick", "Caught in a blizzard", "Stuck in a sinking car", "Encounter an aggressive moose", "Struck by lightning", "Lost in the mountains", "Facing a tsunami", "Struck by hail", "Attacked by a shark", "Caught in a wildfire", "Facing a nuclear explosion", "Encounter a swarm of bees", "Trapped in a mudslide", "Facing a power outage during extreme heat", "Stuck in a collapsing building", "Witness a drowning", "Encounter a rogue wave", "Lost in the desert", "Encounter an aggressive elk", "Facing a hurricane", "Poisoned by a chemical", "Attacked by a wild boar", "Encounter a tornado on water", "Stuck in a cave-in", "Facing a water shortage", "Attacked by a cougar", "Facing a sandstorm", "Stranded in the Arctic", "Encounter a wild buffalo", "Facing a blackout in a major city", "Encounter an electric eel", "Caught in a sinkhole", "Attacked by a large bird", "Facing a gas leak", "Stranded on a cliff", "Attacked by a piranha", "Caught in a snow avalanche", "Stuck in a maze", "Facing a medical emergency alone", "Encounter a rabid animal", "Poisoned by contaminated water", "Lost in an unfamiliar city", "Facing a heatwave without AC", "Witness a robbery", "Encounter a venomous lizard", "Stuck in a traffic jam during a crisis", "Facing a food shortage", "Attacked by a scorpion", "Encounter a wild horse", "Facing a blackout in freezing temperatures", "Stuck on a runaway train", "Attacked by a stingray", "Caught in a tidal wave", "Stuck in a dark forest at night", "Facing a bee sting allergic reaction", "Encounter a wild pig", "Facing a vehicle fire", "Attacked by a jellyfish", "Encounter a wild goat", "Stuck in an abandoned building", "Facing a severe allergic reaction", "Encounter a wild turkey", "Facing a sewage backup", "Stranded on a mountaintop", "Attacked by a lionfish", "Encounter a wild donkey", "Facing a broken bone in the wilderness", "Attacked by a fire ant", "Encounter a wild sheep", "Struck by a falling object", "Facing a ruptured water pipe", "Attacked by a centipede", "Encounter a wild yak"]

And for the Notepad where the texts are displayed:
extends Sprite2D
@onready var input_box = $Input as TextEdit
@onready var output_box = $Output as TextEdit
@onready var button = $Submit as Button
func _ready():
button.pressed.connect(_on_button_pressed)
func _on_button_pressed():
var user_input = input_box.text.strip_edges(true, true)
if user_input == "":
input_box.text = "Please type something!"
return
var node2d = get_parent()
if node2d != null:
node2d.chat_request(user_input, Callable(self, "_on_API_response"), "random_scenario")
else:
print("Parent Node (Node2D) not found!")
func _on_API_response(response_text: String):
var bot_response = response_text.replace(input_box.text, "").strip_edges(true, true)
output_box.text += bot_response + "\n"
And i will upload a photo of the scene`s tree if there is a mistake there…somehow. Also where the random_scenario is chosen it doesnt print the scenario but “random_scenario”.
