To rotate a sprite you can use the following commands :
rotC(Sprite) (rotate 90 degrees clockwise)
rotCC(Sprite) (rotate 90 degrees counter clockwise)

Merci.
Oui je fais des expériences en redstone, par exemple j'ai fait une calculatrice en redstone.

Et c'est vrai que j'avais vu qu'un serveur avait déjà été présenté, mais pour la communauté anglophone. Moi je vous propose un serveur pour la communauté française d'Omnimaga. Je suis d'accord qu'une ville Omnimaga serait bien, il faut juste des gens motivés pour la construire.

Super, je suis nouveau et j'ai hâte de commencer !

Lady and Gentelmen, the Ti-Contest 2012 has started :

The basic features of the contest are kept this year (two round on an imposed subject of one week each, and then 4 weeks to present a personal project), but there are also new features :
- Contest open to student who were born after 1986 (included), who participate in a separate category (except if the number of candidates is too low, but I hope it won't be)
- 2 new categories : Axe Parser and Ti-Basic 68k
- During the correction of personal project a alternate mark system will be used for utiliary programs
- The whole contest will take place during school periods (not on holiday), so that nobody will be disadvantaged (at least in France)
- A new website, including a new members section (more practical), but not finished yet : www.ti-concours.com  (thanks to Matthias Refeyton for the background)

Unfortunately we had to deal with several problems before the beggining of the contest :

- As I just said, the website (members section and design) is not finished : however you can register and be validated, and everything shold be finished before the real start of the contest
- The jury won't be able to note programs on the website, so we will communicate by email, like the previous year
- We were so late that the prizes are not announced yet ! However, we should be able ton announce the prizes before the real start of the contest.

What we still have to do :
- bug if not validated (SQL error)
- menus not finished
- designed to be finsihed (menus transparency, etc...)
- banner
- members section
- bug on the register page : impossible to insert PHP script
etc...

After a very successful Ti-Contest first edition (17 candidates, only tennagers, only in Ti-Basic z80), you are all invited to participate, whatever you level is.
Be aware that even if the contest is in French, you can participate whereever you come from. The only prerequisite ? To have a TI calculator ! Good luck !

Noel Nadal.

Oui, il est possible de faire Buff(2) => ºVAR !
Donc on peut bien créer de nouvelles variables en Axe.

On n'aura jamais fini de connaitre toutes les possibilités de Axe !

Bien joué,
je ne savais pas qu'on pouvait faire ça !

Je vais tester et l'expliquer si je comprends comment ca marche !

I studied your code and spotted another error, which could be also naughty for your calculator :

//Actualisation de la position de l'utilisateur
pUserx += (key == KEY_RIGHT) - (key == KEY_LEFT);
pUsery += (key == KEY_DOWN) - (key == KEY_UP);

//Verification de sa position
if (map1[pUsery][pUserx] == 1 || map1[pUsery][pUserx] == 3 || (map1[pUsery][pUserx] > 4 && map1[pUsery][pUserx] != 14 && map1[pUsery][pUserx] < 21) || pUserx == 21 || pUserx == -1 || pUsery == -1 || pUsery == 13)
{
pUserx -= (key == KEY_RIGHT) - (key == KEY_LEFT);
pUsery -= (key == KEY_DOWN) - (key == KEY_UP);
}
When you check the position of the user and that he tries to go out of the limits, his position will be changed but you will also call map1[pUsery][pUserx] in the if condition...
If pUserx is 21 for example, you will go to a memory place you shouldn't have access to...

I'm not sure but I think you have a memory corruption because when you call malloc for the first time, you will allocate unsigned char for *map.
But in the for loop, the array will contain not an unsigned char, but a pointer so it is a long int.
So the adress to which *map points to will be wrong.
That will cause a corruption when freeing the array.

What you should do is :
unsigned char *map = malloc(MAP_X * MAP_Y * sizeof(unsigned char));

Simple. But addictive.
I like this game because you paid attention to each detail, so it is very nice to play.
Good job !
