If you want to add a method to export save games or something, you could use the clipboard. Basically, when you want to export, serialize the data in a format that you can put into a string. Copy it to the clipboard and display a message to the user that he needs to open a 'save game' document in order to save. The 'save game' document is something that fetches the data out of the clipboard (and checks if it's valid of course) and stores it to a local variable.

If im not mistaken, its what he did in the first place, look at the previous page.

! Update !
Version 0.11.1 is now attached to the first post!

Fixes:
- Doors fixed
- Generated flying water is now surrounded by dirt again
- Attemp to fix advanced crafting menu bug on OS<3.2

@CalebHansberry:
The program is open source, but if you don't have a student software, you can't extract the lua code... I'll pm it to you!
About the 2 layer system: You are not the first who asked for it, but there are several difficulties to translate it to the nspire:
It would take twice as much space for the second tileset to distinguish both layers (I already have more than 50 for the blocks), it would take twice as much space when you save the world, it would take twice as long to save/load both layers, it would take twice as long to update all visible blocks and in some situations it would take longer to render.
I want to finish the main features of the game first, then I'll think about advanced features
Btw: It's written in the header of the script that everyone is allowed to read the code and use parts of it.

@annoyingcalc:
Thanks for the information, you are the first who mentions it! Well, it's something that the crafting menu works anyhow. What exactly doesn't work now? I changed a bit about the menu-switching in 0.11.1 so it maybe works now.

@Jim Bauwens & Levak:
Yep, that's indeed exactly how I did it; it's easy to miss updates here... Good to hear that a professional programmer has the same idea as me

I can't seem to craft at all now -.-

The POTY is coming and your program still wasn't uploaded to ticalc.org
So yeah, Lionel thinks (and he's not the only one) that it would be a pity not to have your program entering that contest, so if you want to, you can upload your program (this one and others) to ticalc and send an email to ticalc admins saying why your program deserves to be featured. And be fast, the deadline is really close.

@Hayleia: Ah, thanks for pointing out, I certainly would have forgotten it! My plan was to upload minecraft 2D to ticalc when it's finished but this is the first contest I'll participate! I'm so excited!

Edit: Ok, file is uploaded and email is sent to [email protected] (?) Now let's hope that it was still in time... when is the deadline?

Great !
Yeah, that seems to be the right adress. And the deadline is December the 1st (you must be featured before this date, not just upload before this date, but I guess it is ok).

It's featured on ticalc.org

Yup, congrats on the feature!

It's games like this that make me want to get a Nspire. Sadly I have to choose between a 3ds, a nspire and a prime. No easy choice!
