Same way you are doing it, just add some more if's for other analog posistions..

oh ok, i was just checking
what if i wanted all way directional movement?
would i have to keep adding if statements?

new question!

well, how would i make a projectile(an arrow) spawn from my character when i press X? it only goes in one direction too, just if you wanted to know

okay, i did this

musicbg = Sound.load("music.wav")

musicbg:play()
Music.volume(128)

but is doesnt work!

Also, what monster said, i would like to know that too!

Okay, how do I make it so that when I press for exampel the X button on a small picture of a circle then the picture changes to a cross? =)

I have an error string 6 on my user lua for 2.0. It also says there is an unexpected symbol, even after I installed the patch. Could this be because I put the new Pspmillionaire in the applications folder?

Know what I mean?

For Monsters thing, you just blit an image a little bit to the right of the characters x posistion, and then add a x = x + 3 or something to the bullets x posistion, so it will increase and go to the right.

can someone help me it keeps saying its running the script but nuttin comes up

i am using lua the latest lua

heres my code

if that doesn't work i'll let you know

EDIT: this is my code:

there is something wrong with it, when i press X it shows my missle like pratically offscreen, it just appears over there

Code:

---

  if pad:cross() then
      bombX = pcXpos
      bombY = pcYpos
      while bombX < 480 do
        screen:clear(black)
        screen:blit(0, 0, menubg)
        screen:blit(pcXpos, pcYpos, sprite)
        screen:print(0, 20, tostring(dx), red) --analog coords
        screen:print(20, 20, tostring(dy), red) --analog coords
        screen:blit(bombX, bombY, missile)
        bombX = bombX + 5 --Controls missile speed
      end
  end
