Same type of variable but two results differents !


Recommended Posts

Hello all,

 

I've got another problem, a strange problem. I use two variables. The first for a score and the second for some potion. There are identical by the type. But score can increase and potion stay to 0...

 

What's wrong ?

 

/* DEFINIE VARIABLES HERE */
unsigned int score;
unsigned int potion;

...

/*POTION*/
void findpotion()
{
cls (); // Clear Screen
show_score();
center_string (3,"YOU FIND A POTION");
center_string (17,"YOU WIN 200 pts");
center_string (23,"PRESS FIRE");
delay (50);
pause();
score = score + 200;
potion = potion + 1;
engine();
}

...

/* SHOW SCORE & POTION*/
void show_score()
{
print_at(0,0,"Score"); put_at(6,0,str(score),5);
print_at(14,0,"Potion"); put_at(21,0,str(potion),1);
}
...

void main()
{
/* DEFINE SCREEN MODE */
screen_mode_2_text(); // DEFINE SCREEN MODE
fill_vram0(0x2000,0x1800,0xf0);
/* DEFINE ASCII TEXT */
upload_default_ascii(NORMAL);
duplicate_pattern();
/* ASSIGNATION POTION 1 IN BEGINNING GAME */
potion =1;
/* START NEXT FUNCTION HERE */
splashscreen (); // CALL SPLASHSCREEN FUNCTION
}

You forgot to include the splashscreen() function in your posted code.

 

But anyway, I think I see your problem: The last parameter of put_at() is the byte size of the string, and you're passing weird values for that parameter in your code. You should use "print_at(6,0,str(score));" and "print_at(21,0,str(potion));".

put_at(21,0,str(potion),1); will only print 0. Because the full string is 00001, and it only going to print 1 character. If he have it put_at(21,0,str(potion),5); then it'll show 00001 potion.

If you want a single digit to print for your potion, then put_char(x,y,potion+48); will work 0-9. It points at the tileset.

Double digit needs a MOD of 10 and division of 10 to a temporary variable and then 2 put_char() side by side to show double digit.

For double digit, i think you can do also simply that :

 

put_at(21,0,str(potion)+3,2);
