Meh, then thanks anyway. I could work around that...Do you know how to code menus? Because if you do, then just PM me, because I could use you for this app.

---

i could help. i have just written a guide on menus. search "menus in lua" and youll see it. or i can do it for you.

SO MUCH THANKS! And also, another problem. (I never stop having problems) This should be the last one. In my code I have:

Code:

---

r = 0
d = r*2

function caf()
x = r*r*3.14
end

function cac()
y = d*3.14
end

---

Yet as r increases, d stays the same. If i set r as 1, d would show up as d = 2, and never go up no matter how much r goes up. THis is the final problem, (I hope!)
THANKS again.

This is because you only defined "d" in the top of your code.
It isn't anywhere in your loop so it can't be updated. It's only created at the top of your code. You need to either put it somewhere in your loop to update the variable, or into a function that gets called.

how would you 'refresh' a randomly chosen number,
so when i tell it to, it will randomize again,(pick a new number)

Do it the same way you made the first number.

If you did

Code:

---

number = math.random(1,10)

---

to get the first number then just call that command again wherever you want a new random number.

I would also recommend at the top of your code before your loop to "seed" your random numbers so that the same ones arent generated each time you run your app.Here's a good way to do that.

Code:

---

math.randomseed(os.time))

---

That's a good way

thanks,,

screen:save("ms0:/PortablePaint.tga") to save to root of ms, or
screen:save("ms0:/PSP/SCREENIES/PortablePaint.tga") to save in "screenies" folder within the "psp" folder on the ms.

thank you so much dragon
