Day night cycle

Hi! I made a function to add a day night cycle. It shifts the palette and takes two arguments, hour and minutes. The palettes can be modified.

First you can see it in action here:

Thing to note

  • The night palette is very different from the rest, adjust it based on your sprites. Originally this palette was made by Achie72
  • It is very token intensive at the moment. That can surely be optimized by either cleverly contstructing the palettes at runtime or deleting those you don't use. But I kept it like this for readabilities sake.
  • Maybe adjust the time to your needs. I took a shorter day as a model but you could also change the times(ho=hour in the function) in code
 
function set_pal(h,m)
local pals={

    elseif ho==21 then
        if(m<30)pal(pals[2],1)
    elseif ho>21 then
        pal(pals[1],1)
    end
end

I hope this is useful, have fun with it!
