You have the entire rights to make any program for learning purposes - but if you're not making this program for learning purposes, maybe you could join forces with Torio ?

If he want, why not! Even if I learn C with this program, it can be a serious project if it works but now it's still a test game.

OK, it's good if you're still learning. I just wanted to make sure that you were not both, in the exact same time frame, aiming at making a release-quality Pokemon port

It's not pokémon but zelda (at the beginning i wanted to make a pokemon game but now it's more a zelda game, i am too tired to rename files... ^^')

I'm busy enough with Pokemon for now, so I'm afraid I won't be able to start another project.
However you can still ask me questions if you have problems with your game !

I didn't look at his archive further than the name, so I tried to make sure that you two weren't making the same thing; but they're projects with little in common, so you wouldn't be able to work much on each others' project anyway

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

Code: [Select]

//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...

Yes youre right but im not changing value of memory adress so its ok isnt it?

You're not writing out of the bounds of the buffer, but you're nevertheless reading outside the bounds... which is unlikely to yield correct behaviour down the road

Kiligolo · « **Reply #39 on:** February 18, 2012, 08:13:53 am »

It's an OR condition : if pUserx = 21 it's true and map[pUsery][pUserx] is useless so it's ok.

Torio · « **Reply #40 on:** February 18, 2012, 09:00:12 am »

map[pUserX][pUserY] is useless but it will read the data out of the bounds, though. The simple fact of trying to read out of the bonds of the buffer can be naughty for the calculator.

Note, if you decide to take on a Zelda project, you should probably make a small game as your first project to start with, since a larger Zelda would be a huge project if you are still beginning with C. My Zelda clone only had 3 dungeons and I had 3 years of experience in TI-BASIC when I made it.

It's nice to see you around again by the way

(just make sure to not do the grammar police in the French section like in 2010, though

). I thought you lost interest in calc-related stuff since you were not on TI-Planet/bank either.

Zelda is a goal.

Ok that's good I guess.
