Hi
This is my first attempt at scripting, but I'm have issues getting this to work.

Basically, I want the player to answer some questions where they get 10 points for a right answer and -10 for a wrong answer. But I just can't get it to work, because scripting isn't my thing and like I said this is my first attempt.

See Script Below.

-- Quiz Script

-- Initialize score
score = 0

-- Questions and Answers
questions = {
{
question = "What is the capital of France?",
answers = {
"Berlin",
"London",
"Paris" -- Correct answer
}
},
{
question = "Which planet is known as the Red Planet?",
answers = {
"Earth",
"Mars", -- Correct answer
"Jupiter"
}
},
-- Add more questions as needed
}

-- Current question index
currentQuestionIndex = 1

-- Function to display the current question and answers
function DisplayQuestion()
-- Display the question
Print("Question: " .. questions[currentQuestionIndex].question)

-- Display answer options
for i, answer in ipairs(questions[currentQuestionIndex].answers) do
Print(i .. ". " .. answer)
end
end

-- Function to check the player's answer
function CheckAnswer(selectedAnswer)
local correctAnswerIndex = 0

-- Find the index of the correct answer
for i, answer in ipairs(questions[currentQuestionIndex].answers) do
if answer == questions[currentQuestionIndex].answers[1] then
correctAnswerIndex = i
end
end

-- Check if the selected answer is correct
if selectedAnswer == correctAnswerIndex then
Print("Correct!")
score = score + 10
else
Print("Wrong!")
score = score - 10
end

-- Move to the next question
currentQuestionIndex = currentQuestionIndex + 1

-- Check if there are more questions
if currentQuestionIndex <= #questions then
DisplayQuestion()
else
Print("Quiz completed! Your final score is: " .. score)
end
end

-- Display the first question when the game starts
DisplayQuestion()

Hello,

I spent my day on a quiz compatible with Game Guru MAX.
(problem : I don't remember how I can attach the code in this comment. The Selection of 'Code' in the editor doesn't work in Microsoft Edge.)

1. Copy the 'quoted script' (don't include the " placed by the editor at the start and at the end of the script).
2. Save it as 'quiz.lua' somewhere in the subfolder 'scriptbank\user' of your main user files of GameGuru MAX (optionally defined as the 'writable folder location' if modified in the 'Advanced Settings' of the Editor.
3. You could dedicate a .png icon to identify that script but it is not absolutely necessary because the name of that script will appear in the selection of the behaviors thanks to its description.
4. start a new project with a new level (an empty landscape is good enough to test that script) .
5. add an asset of your choice having these properties :
physics off + always active + isimmobile
6. select that script 'quiz.lua' and attach it as behavior to that asset.
7. save your level and test it.
