p.s. it still is only in lua

System.usbDiskModeActivat e()

green=Color.new(0,255,0)
orange=Color.new(255,128, 0)
teal=Color.new(64,128,128 )
blue=Color.new(0,0,255)
red=Color.new(255,0,0)
black=Color.new(0,0,0)
lightgreen=Color.new(0,25 5,128)
lightyellow=Color.new(255 ,255,128)

redballX=200
redballY=150
redballColor=blue

background = Image.load("pic/background.png")
redball = Image.load("pic/redball.png")
redballblue = Image.load("pic/redballblue.png")
redballred = Image.load("pic/redballred.png")
redballorange = Image.load("pic/redballorange.png")
redballgreen = Image.load("pic/redballgreen.png")
redballteal = Image.load("pic/redballteal.png")
redballblack = Image.load("pic/redballblack.png")
redballlightgreen = Image.load("pic/redballlightgreen.png")
redballlightyellow = Image.load("pic/redballlightyellow.png")

while true do
screen:clear()
pad=Controls.read()
if pad:cross() then screen:blit(redballX, redballY, redball)
elseif pad:triangle() then screen:blit(redballX, redballY, redballblue)
elseif pad:circle() then screen:blit(redballX, redballY, redballlightyellow)
elseif pad:square() then screen:blit(redballX, redballY, redballorange)
elseif pad:start() then screen:blit(redballX, redballY, redballgreen)
elseif pad:l() then screen:blit(redballX, redballY, redballteal)
elseif pad:r() then screen:blit(redballX, redballY, redballlightgreen)
elseif pad:select() then break
end

if pad:up() then redballY=redballY-5
elseif pad:down() then redballY=redballY+5
elseif pad:left() then redballX=redballX-5
elseif pad:right() then redballX=redballX+5
end

screen:blit(redballX, redballY, redball)
screen.waitVblankStart()
screen.flip()
end

p.s. the colors are only for future reference

[Jeremy1026]

it looks like u need to clear the screen before u reblit the new image...but, im no genius, there is someone that should know more than me...but thats my assesment of #2, as for number one, i dont even see ur background image code in there. besides when u call it for future reference

[Twenty 2]

ok if u want ur background to be in the "background then blit it to the screen before the rest of the images

[slicer4ever]

i had the code in there earlier but i forgot to put it back in berfore i posted it anyways is there a way to just make the background without an actuall pic i read it somewhere but now i cant find it

[XteticX]

Hey, I just posted soemthing similar for you , but just in case you dotn see it, I'll post again. :icon_wink You have too many blits in there. You should just create a new variable, something like "CurrentBall" and have your script blit its value only once. That way, when you press a button, you only have to change the value of "CurrentBall".... like CurrentBall=redball whatever. Simpler that way.

If its only a one color background then just draw a rectangle across the screen.

screen:fillRect(0,0,480,272,color)

Sorry for double post.

   screen:blit(redballX, redballY, CurrentBall)
   screen.waitVblankStart()
   screen.flip()
end

o, ok i see thanks you guys are very helpful

[slicer4ever]

i wrote that code into mine to make sure it works before i implimate it to my own liking but i keep getting a error:

error:= expected near e

u no the rest anyways i have beeen looking though the code but i cant seem to figure out what the error means so could yea help i'm ganna go back though but help would be appreciated.

nvm i think i got it

[b0xx0r]

In the post with the code, it inserts spaces. For example when it says USBDiskActivat e() it should be USBDiskActivate(), with no spaces.

[sumpaintballer41]

ANy particular reason for activating the USB drive??

[Twenty 2]

Read his post it was an example...
