I can't manage to get your error, but, if I save the function (you forgot to do so ?) with Ctrl+B, and reevaluate the last sample, I get an infinite loop in exp2vector() on line 6. In a way, I don't understand anything about the numerical assignations inside exp2vector(), but I think you tried to convert a0 * X0^n + a1 * X1^n-1 + a2 * X2^n-2 + ... + an to [a0, a1, ..., an] didn't you ? Because you can do this with the built-in function polyCoeffs() (available at least in OS 3.0, don't know if it exists before) and returns {a0, a1, ..., an}.

I Hope this helped you.

Though, it wasn't an "entire" website, since we have only 4 tutorials that helped many people (I didn't expected so much). Thus I think he should read those, because they weren't very long, before starting and asking those question. I really like the RTFM method, since it really helps people searching by themselves. It is evident that, when there is no answer, or the answer is really complicated, we help this person, since he will search for many hours and doesn't find it afterall and come back again.

I'm sure we can come between those two ideas =)

function on.paint(gc)
 if mX and mY then
  gc:setPen("sansserif", "r", 18)
  gc:drawString("You pressed at ("..mx..", "..my..") coordinates", 0, 0, "top")
 end
end

function on.mouseDown(x, y)
 mX, mY = x, y
end


So it would go like this:

The mouse is already controlled by the touchpad, no need to program this.
on.mouseDown is when the mouse is clicked, it reports that it was clicked and at what coordinates it was clicked at. What is the syntax for on.mouseDown?

This question is part of the "Starting in Lua" tutoring part. I guess you should look at it before beginning a project (we haven't finished the EN part ... sorry)


To answer quickly : on.mouseDown(x, y)

Here is a list of all of the keys that can be "controlled" with Lua

Where is the list?

All the "basic questions" like this one are answered when looking at http://www.inspired-lua.org/  and http://wiki.inspired-lua.org/

The final version is here !
I attach it in the first post, and in this post too.
It works on OS 3.0.2, as I used the official TI scripting tool, with the 30-days trial.
So thank you for all your help and replies, and I forgot to thank you for all your welcoming posts

Wait, 30-day trial?

He used the official TI scripting tool. To use it you need TI Nspire Computer Software. But since TI-Nspire Computer Software is under licence and we need to pay for it, Chockosta used the trial version of TI-Nspire Computer Software. But one thing is that it is not a 30-days trial, but a 90-days trial =)

If it could help you to understand :

Wait... you can read that thing?

Where is the problem ? We can do this since a while ... The more important thing to know is that the data base part (like strings, keys of strings, and the Lua part) are readable without dissassembly procedure.
