buttons state simplification

Questions
1

I’m quite a beginner and I’m writing some test code, a very simple game, that requires to press some buttons.
In my draw function I have this:

function draw()
    -- This sets a dark background color 
    background(223, 210, 175, 255)

    -- Do your drawing here
    fader:draw()
    score:draw()
    scene()
    for i = 1, buttons.number do
        buttons[i].state(i)
        buttons[i].m:draw()
    end

end

buttons[i].state is a pointer to another function like run or stop.
Here is an example of the run state:

function run(i)
    buttons[i].m.shader.freq = freq
    buttons[i].m.shader.time = buttons[i].m.shader.time + 0.25
    if buttons[i].m.shader.time > 10 then
        buttons[i].m.shader.freq = 0
    end
    if buttons[i].m.shader.time > 15 then
        buttons[i].state = stop
        buttons[i].m.shader.time = 0
        print("button stopped = "..i)
    end
end

Can I make a cleaner code? I don’t like that buttons[i].state[i]. Problem is that I have 6 different buttons.

Thanks

make a Button class

here is the idea

function setup()
    -- create your buttons in setup
    for i=1,6 do
        buttons[i] = Button(i)
    end
end
    
function draw()
    -- This sets a dark background color 
    background(223, 210, 175, 255)

    -- Do your drawing here
    fader:draw()
    score:draw()
    scene()
    for i,b in pairs(buttons) do
        b:state()
        b.m:draw()
    end

end

Button = class()

function Button:init(i)
    self.i = i
end

function Button:run()
    self.m.shader.freq = freq
    self.m.shader.time = buttons[i].m.shader.time + 0.25
    if self.m.shader.time > 10 then
        self.m.shader.freq = 0
    end
    if self.m.shader.time > 15 then
        self.state = stop
        self.m.shader.time = 0
        print("button stopped = "..self.i)
    end
end

how should I call the button class to change state? something like buttons[i]:run ?

this is already in the line

        self.state = stop

you never have to use buttons[i] directly, you just define the action in a Button class function, and the button is self

6

the starting state can be defined in the init()

function Button:init(i)
    self.i = i
    self.state = self.run
end

it would be easier to show you if you posted a very simple full example. Working on non functionnal code parts is not practical.

Thanks!
I did not post the entire code thinking it was too long. I’ll try with your advice and in case I’ll post the entire code if still in difficulty.

do you know about class() concept? If not, read about it in ignatz ebook first.

I’m not that familiar actually. Where I can find the latest copy of the ebook?

I’ve found it on Ignatz website (coolcodea).

@Kotas I made a menu class that held a set of related buttons. I pass touch to the menu class and it handles which button was pressed and draws them accordingly. It then returns the index of which button was pressed that corresponds to the index that I put that button into the parameters for the menu instance, and then touch makes the required calls for what that button controls. Don’t know if this helped but good luck.

@Goatboy76 It’s very similar to what I need. I’ll try to structure based on your suggestion. This is for me a good way to make practive and understand better the language.

@Kotas Cool, let me know if you want me to post my Menu and Buttons classes.
