Name is a zero length array. So it has nothing in it.
Try this:
global- Code: Select all
char NAME[6];
strcpy(NAME, "jimmy\0");

You are right. I now explain better.
I want to stamp a list of actor and their characteristics:
HERO [0] <--Joe Eroe
HP[0] = 10;
MP[0] = 8;
.............
HERO [1] <--Jimmy
HP[1] = 45;
MP[1] = 0;

Ok, so it is an array of arrays.
You can declare an array or strings (character arrays) like this.
- Code: Select all
char *names[] = {"name_one", "name_two"};

Well I have understood.
I thank really a lot as always you for the help.
________________________________________
A curiosity': in GAME MAKER:
draw_text (a)
draw_text (b)
draw_text (c) with an alone actor,
but in GE he is not possible to stamp + lines of text with an alone actor - > draw text?
sprintf(.... , y += 10)
sprintf(.... , y += 20)....... ??

By the way, you could also make structs to hold this data, and then make an array of structs.

warning, advanced topic
- Code: Select all
struct hero {
char *name;
int hp;
int mp;
} heroes[2] = { {"hero one\0", 10, 10}, {"hero two\0", 5, 15} };
Then you could access it like this
- Code: Select all
sprintf(text, "name %d : %s\n", i, heroes[i].name);
hp.textNumber = heroes[i].hp;
mp.textNumber = heroes[i].mp;
(And, yes, I know what you mean about the difference between GM and GE. )

I really glorify the example struct.
In GAME MAKER it doesn't exist.
But now thanks to you, i study it and everything that that you have taught me.
I now create a small example RPG.
