Lua Programming Help Thread

why un-sticky this? its used so often it just doesnt make sense to me to make it harder to find.

Read what i wrote.

I prefer it just being up the top than just clicking on a thread then getting the link to go here... :(

Its def. not the second part.

I tried something and now i get

Code:

---

error:attempt to index field '?' <a nil value>

---

anyone know what that means?

---

answer please

if its not stickied, you can just add it to your favorites, yet i think it should have stayed stickied, so other people can directly see this thread.

how can you flip an image
(preferbly in v16)

I was wondering if you could use LUA Player to calculate the TOTAL space on the memory stick? , If so could someone post the code for it. Thanks.

mem = System.getFreeMemory() -- gets free memory at least.

i'm not sure if thats what you wanted since you said TOTAL space, but maybe that will help anyways.

Well I tried getfreememory(), heres the code :

Code:

---

mem = System.getFreeMemory()
screen:print(200, 100, mem)
screen.flip()

while true do
screen.waitVblankStart()

end

---

It gives me the wrong values when I do it.. :Argh:

Wouldn't the code be:

Code:

---

white = Color.new(255,255,255)

mem = System.getFreeMemory()

while true do
screen:clear()
screen:print(100,100,"Free Memory = " .. mem, white)

screen.waitVblankStart()
screen.flip()
end

---

Try that instead.
