How do you make an animation in lua? Can you use gifs or what?

this is a bit confusing to explain, but i want a way,
when the timer has started, and when a button is pressed, to record the time of the timer at the time the button was pressed, in another file like this
file = io.open("test.lua","a")
file:write("\n[whatever the time is]")
file:close()
how would i do that?

---

file = io.open("test.lua","a")
pad = Controls.read()
if pad:start() then
file:write(os.time())
end
file.close()

but would that work with a timer,
i though os.time was the clock?

Can anyone get the voice:playing() function working?

Correct, use multiple png images, then use a timer to display them.

can someone give an example of how to make a 3 picture smilie animation? I want him to talk.

Well, if you want each frame of the smilie to last for 8 milliseconds, you'd do this:

[HTML]
frame_1 = Image.load("frame_1.png")
frame_2 = Image.load("frame_2.png")
frame_3 = Image.load("frame_3.png")
screen:clear()

while (true) do
--Put image to memory and flip it to screen
screen:blit(0, 0, frame_1)
screen.flip()
--Keep frame showing for 8 milliseconds
screen.WaitVblankStart(8)
--Clear screen to start over
screen:clear()

screen:blit(0, 0, frame_2)
screen.flip()
screen.WaitVblankStart(8)
screen:clear()

screen:blit(0, 0, frame_3)
screen.flip()
screen.WaitVblankStart(8)
screen:clear()
end
[/HTML]

There's probably an error in there somewhere, but that should be a fair idea of how you do it.
