Prototype math flash card app

Code Sharing
1

A while back I was looking into an app to help kids learn their math more easily. I stopped work on it because to put out an apple app you need an Apple dev license. But I would hate to see my work forgotten so anyone who wants to play around with it here it is

Not every thing is polished or completed, but the core of it works like a charm. It even can square and cube things.
It accounts for answers to the “flash cards” which might be a negative number and allows you to leave negative answers. Have fun.

A shoutout to this awesome code teacher. This tutorial series has some really good stuff.
The manner in which I finally got actual buttons incorporated comes from there.

My code will be left in comments because of character limit in body.

This code segment needs to be in a tab named ‘Button’

    self.displayName = displayName
    
    self.pos = vec2(0,0)
    self.size = vec2(0,0)
    self.action = nil
    self.color = color(255, 0, 33, 255)
end

function Button:draw()
    -- Codea does not automatically call this method
    pushStyle()
    fill(self.color)
    
    font("ArialRoundedMTBold")
    fontSize(22)
    
    -- use longest sound name for size
    local w,h = textSize(self.displayName)
    w = w + 40

    fill(255, 255, 255, 255)
    text(self.displayName,self.pos.x,self.pos.y)
    
    popStyle()
end

       p.y > b and p.y < t then
        return true
    end

@Archimedes - it is easier for people if you put long code like this into a gist (or something similar)and post the link here.

To get the code to paste into separate tabs,

  1. to copy it, go out to the main Codea screen with the project list, press on your project until you get the copy option. This copies the whole project and tags each tab.

  2. paste into gist (or whatever)

  3. other users can then copy it from there. If they press and hold the Add new project button, they will be given the option to paste into project. This splits the code into all the tabs.

Ok thanks.

@firewolf, i have some math homework here if you want it! Lol, jk =))
