sorry to ask a rudimentary question, but i am relatively new to graphics

if i wanted to fill a cylinder type object up one line of pixels at a time:

_
| |
| |
| |
| |
_

(imagine each row is 4 pixels wide or something)
what is the best way to do this?

just make a for loop to drawline one at a time?

Here's something that might help. Sorry for the lack of proper explanation, but this code basically eases a menu up, so it goes faster then gradually slows down.

Code:
function ConceptCreate:CloseMenu()
   menuopenfull = false
   while menuposy < 273 do
      screen:clear()
      Concept:Render()
      Concept:Menu()
      screen.waitVblankStart(1)
      screen.flip()
      if menuposy < 273 then
         menuposy = menuposy + 1
         if menuposy < 260 then
            menuposy = menuposy + 2
            if menuposy < 250 then
               menuposy = menuposy + 3
               if menuposy < 240 then
                  menuposy = menuposy + 4
                  if menuposy < 230 then
                     menuposy = menuposy + 5
                     if menuposy < 220 then
                        menuposy = menuposy + 6
                     end
                  end
               end
            end
         end
      end
   end
   screen:clear()
   Concept:Render()
   menuposy = menuposy + 1
   screen.waitVblankStart(1)
   screen.flip()
end

function ConceptCreate:Render()
   Concept:RenderBaseImages()
   
   if menuopenfull == true then
      Concept:Menu()
   end
end

function ConceptCreate:RenderBaseImages()
   screen:blit(0,0,bg)
end

function ConceptCreate:Menu()
   screen:blit(menu_viewimagesposx,menuposy + 10,menu_viewimages)
   screen:blit(menu_viewmusicposx,menuposy + 20,menu_viewmusic)
   screen:blit(menu_viewprogramsposx,menuposy + 30,menu_viewprograms)
   screen:blit(menu_explorerposx,menuposy + 40,menu_explorer)
   screen:blit(menu_systeminfoposx,menuposy + 50,menu_systeminfo)
   screen:blit(menu_utilitiesposx,menuposy + 70,menu_utilities)
   screen:blit(menu_closeposx,menuposy + 90,menu_close)
end

Might be a little complex for what you want, but yes, if you don't use this, you could use a drawline loop (;

simplest way would be a for loop with a 4 pixel wide rectangle (instead of 4 lines).

not really in relation to the preceeding, but i didn't feel like starting a new thread

if i have something like this:

Code:
         if marked[i][j] == 1 then
            strpiece = hor
         end

         if marked[i][j] == 2 then
            strpiece = vert
         end

         if marked[i][j] == 3 then
            strpiece = tjunct
         end

         if marked[i][j] == 4 then
            strpiece = ld
         end

         if marked[i][j] == 5 then
            strpiece = lu
         end

         if marked[i][j] == 6 then
            strpiece = rd
         end

         if marked[i][j] == 7 then
            strpiece = ru
         end
      end
   end

   screen:blit( 16 * (i - 1) + 236, 16 * (j - 1) + 28, strpiece)


it gives me an error because strpiece isn't a picture. how would i go about assigning the picture names (tjunct, ru, vert, etc) to a variable that lua would output when i do the bottom line, screen:blit ?

This is a problem I've hit. I fixed it with

Code:
if strpiece == ru then
       code
end
