i'm new to luaplayer and i would like some help knowing whats wrong with my options menu ever since i added it, it just closes down while using luaplayer for windows...

Code:

   if pad:cross() then

           ShowOptions()
      end
end


would this be the way to show my option menu with a function?

here is what my option menu coding is

Code:


function ShowOptions()

screen:blit(0, 0, IMGOptionsMenu)
      screen:blit(340, 84, IMGSlow)
      screen:blit(356, 127, IMGNormal2)
      screen:blit(366, 174, IMGFast)
      screen:blit(366, 174, IMGBack)

   if selectedOption == 1 then

   screen:blit(340, 84, IMGSlow2)
      screen:blit(356, 127, IMGNormal)
      screen:blit(366, 174, IMGFast)
      screen:blit(366, 174, IMGBack)

   elseif selectedOption == 2 then

   screen:blit(340, 84, IMGSlow)
      screen:blit(356, 127, IMGNormal2)
      screen:blit(366, 174, IMGFast)
      screen:blit(366, 174, IMGBack)

   elseif selectedOption == 3 then

      screen:blit(340, 84, IMGSlow)
      screen:blit(356, 127, IMGNormal)
      screen:blit(366, 174, IMGFast2)
      screen:blit(366, 174, IMGBack)

   elseif selectedOption == 4 then

      screen:blit(340, 84, IMGSlow)
      screen:blit(356, 127, IMGNormal)
      screen:blit(366, 174, IMGFast)
      screen:blit(366, 174, IMGBack2)

   end

   screen.waitVblankStart()
   screen.flip()

end

   pad = Controls.read()
   
   if pad:left() then

   if selectedOption > 1 then
 
      selectedOption=selectedOption-1

   end

   end
   
   if pad:right() then

   if selectedOption < 3 then
 
      selectedOption=selectedOption+1

   end

   end   

   if pad:cross() then

   if selectedOption == 1 then

        ballspeed  = 100
        selectedOption == 4

   elseif selectedOption == 2 then

        ballspeed   = 200
        selectedOption == 4

   elseif selectedOption == 3 then

        ballspeed   = 300
        selectedOption == 4

   elseif selectedOption == 4 then

        Menu()

   end

   end


i know that all images are loaded and i know that 2 of them go into the same place i'll put them where i want after :P
and this is my varible for selectOption

Code:

selectedOption = 2 --[[
          1 - slow;
          2 - normal;
          3 - fast;
                    4 - back;

      ]]--


once i get this working hopefully i can save the settings just like shine's snake :)

Looks like the code you quoted with your "ShowOptions" function is more code than just this function, but it is hard, because the idention is strange.

You can call it as a function, but when it returns, it will be displayed only once. If you like, you could take a look at the Snake game source code.

The best solution would be a general event based library, which removes the need of the game-loop, because looks like this makes it harder than needed for Lua Player beginners. This could be implemented in Lua and could look like just some class, where you need to overide onPaint, onCross, onLeft etc., only and then call some internal event loop, which is provided by the class. This is the point A LuaPlayer library for cooperative multitasking, clipping regions (windows), cursor, “mouse” and keyboard events, and stuff like that on http://wiki.ps2dev.org/psp:lua_player:todos , which doesn't mean that nevyn or I have to do the work alone :-) (we are busy for the next weeks with porting to different operating systems, preparing the conference talk, sound enhancements and OpenGL implementation)
