you have to make it into a looping thing

(dont ask me about it though, i only program a little bit)

but here is the problem, your program runs, and doesnt check again, you have to get it to run and check

code: (im not sure if this is right)

while 1
if pad:cross() then
screen:print(10,10,"TEST TEST TEST", red)
screen.flip()
end

---

Close but no cigar yet...

Code:

---

while true do
pad = Controls.read()
if pad:cross() then
screen:print(10,10,"TEST TEST TEST", Color.new(255,0,0))
screen.waitVblankStart()
screen.flip()
end

---

Give that a whirl...

If I do what you said SG57, with the screen.waitVblankStart() and screen.flip() under the pad:cross(), it flickers when I hold X, and doesn't stay there when I press it. :(

Then you probably have a screen.flip() somewhere in your code (probably near the end) and it's reflipping it. Try taking out the screen.flip() in SG57's code and see what happens.

Code:

black = Color.new(0, 0, 0)
white = Color.new(255, 255, 255)
grey = Color.new(127,127,127)
red = Color.new(255, 0, 0)
green = Color.new(0, 255, 0)
blue = Color.new(0, 0, 255)
yellow = Color.new(255,255,0)
purple = Color.new(120,0,120)
pink = Color.new(255,0,255)
orange = Color.new(255,110,0)

ms = 0
x = 0

while true do
screen:clear(black)
pad = Controls.read()

if pad:up() then
ms = ms - 1
screen.waitVblankStart(4)
end

if pad:down() then
ms = ms + 1
screen.waitVblankStart(4)
end

if pad:cross() then
screen:print(10,10,"DUHDUHDUH", white)
screen.waitVblankStart()
end

screen.waitVblankStart()
screen.flip()
end

---

If i try the above code then it stays there when I HOLD X, and just appears then disappears if i press it. :Argh: :( :Argh: :( :Argh: :( :Argh: :(

Code:

---

if pad:cross() then
if duh == false then
duh = true
elseif duh == true then
duh = false
end
end

if duh == true then
screen:print(10,10,"DUHDUHDUH", white)
end

---

Okay... I'm a little confused right now (I'm about to fall asleep on my keyboard). Well anyway, I have created an empty image that is 480x272. I want to store my two background images in there so it only blits what is shown on screen. Can anybody show me how to do this? I think I would get it if I had a good night's sleep.

Thanks,

Is there any way to make an action ocur only if a certian two buttons are pressed at the same time? Thank you for your time :icon_smil
