How to implement the generation of buttons with answers?

Questions

Hello @Regven!

Here is what I’d do:
Have 3 gui nodes, one text node to hold the question, a button for yes and one for no.
Then I would use a module (Lua modules in Defold) containing a table to hold the questions and the expected answers, eg:

questions.lua

local M = {}

M.questions = {
	{"1 + 3 = 5", false},
	{"10 + 10 = 20", true},
	{"10 / 2 = 5", true},
	{"6 + 4 = 11", false},
	{"2 + 3 = 5", true},
	{"1 * 1 = 2", false},
}

return M

Require the file in your script and assign a local variable to it, eg like so:

local m = require “main.questions”

Then you can access question and solution like so using the number of the question:
local question = m.questions[question_number][1]
local solution = m.questions[question_number][2]

Set the text of the text node to the question.

Next get the answers:
If “yes” is pressed:
answer = true
if “no” is pressed:
answer = false

Compare answer and solution:
if equal, the answer is correct, add one point, if not, the answer is incorrect, deduct a point.

This leaves you with the number of the question.
I assume, you want the question to be both random and not repeating:
Take a look here:

Check out the Lua manual about math.random and math.randomseed, here eg:
