Hallo Game-Studio Community ich hoffe ihr könnt mir bei meinem Problem weiterhelfen. GER:
Meine Problemstellung ist es einige structpointer des typ HERO und einige structpointer des typ MONSTER im Heap zu allocieren. ich hab es so gelöst:ENG:
My problem is to allocate a few structpointer from type of HERO and a few from type of MONSTER in the heap. I've solved it this way:
typedef struct MONSTER
{
...
var INIT_M;
...
}MONSTER;
typedef struct HERO
{
...
var INIT;
...
}HERO;
//initialisierung über enmies_create() und hero_create()
MONSTER* create_enemies()
{
MONSTER* enemy = (MONSTER*)malloc(sizeof(MONSTER));
...
enemy->INIT_M = 14;
...
return enemy;
}
int hero_order[3] = {0,1,2};
int cur_hr = 0;
HERO* create_hero()
{
HERO* hero = (HERO*)malloc(sizeof(HERO));
...
switch(hero_order[cur_hr])//hero_order enthält die werte 0,1,2
{
case 0:
...
hero->INIT = 16;
case 1:
...
hero->INIT = 12;
case 2:
...
hero->INIT = 15;
}
...
cur_hr++;
return hero;
}
//direkte übergabe des pointer an andere HERO pointer
void create_battle_startup()
{
HERO* hero0 = create_hero();
HERO* hero1 = create_hero();
HERO* hero2 = create_hero();
MONSTER* monster0 = create_enemies();
MONSTER* monster1 = create_enemies();
MONSTER* monster2 = create_enemies();
i= hero1.INIT; //hier entsteht das Problem
// i = 408
...
nachdem ich also die structs initialisiert habe und übergeben hab, liest er einen falschen Wert für Init aus. theorethisch müsste hero1.INIT die 12 beinhalten, zum Zeitpunkt der initialisierung tut sie das auch nur am Zeitpunkt nach der Übergabe enthält sie einen anderen Wert. ich habe es auch bereits kontrolliert, ob der Pointer "hero1" vieleicht eine andere adresse enthält aber er hat genau die adresse welche er bekommen soll nur ist einzig und allein der INIT wert fehlerhaft. Es ist nun ziemlich schwer dafür noch eine sinnvolle erkläung zu finden und ich würde mich freuen wenn mir jemand erklären könnte was ich falsch mache.ENG:
after I've initialize and handed over the structs to the other pointer hero0,hero1 which works fine the compiler read out a wrong content of hero1.INIT. In theory hero1.INIT should content the 12 instead of 408. it's really hard for me to understand this matter because the transfer of other components like ATTACK, DEFENSE works fine only the INIT component gives me headache. I'd be very grateful if there is someone how could explain what is wrong with my considerations.

Cant sprechen Deutsch leid, Übersetzen von Google, aber versuchen Sie dies.
switch(hero_order[cur_hr])//hero_order enthält die werte 0,1,2
{
case 0:
...
hero->INIT = 16;
break;
case 1:
...
hero->INIT = 12;
break;
case 2:
...
hero->INIT = 15;
break;
default:
hero->INIT = 99;
break;
}
Oder wenn dies nicht mehr benutzen, sicher, dass Sie "cur_hr" zu sein beim Start NULL gesetzt. Hope this helps.

thanks for the quick answer, but the advise didn't solve the problem. sicher, dass Sie "cur_hr" zu sein beim Start NULL gesetzt. yes I set it to "0" at the beginning.. The switch loop I think doesn't pose the problem, because there are other statements in the jump marks, which works fine like "ATTACK", "DEFENSE" ect.

Hero[curhero].init=whatever
Im on my cellphone so cant sroll down your code but curhero must be increased i only write hero[] if you think of making array

Hi, I tested with the following code and it is working fine for me.
typedef struct MONSTER
{
var INIT_M;
}MONSTER;
typedef struct HERO
{
var INIT;
}HERO;
//initialisierung über enmies_create() und hero_create()
MONSTER* create_enemies()
{
MONSTER* enemy = (MONSTER*)sys_malloc(sizeof(MONSTER));
enemy->INIT_M = 14;
return enemy;
}
int hero_order[3] = {0,1,2};
int cur_hr = 0;
HERO* create_hero()
{
HERO* hero = (HERO*)sys_malloc(sizeof(HERO));
switch(hero_order[cur_hr])//hero_order enthält die werte 0,1,2
{
case 0:
hero->INIT = 16;
break;
case 1:
hero->INIT = 12;
break;
case 2:
hero->INIT = 15;
break;
}
cur_hr++;
return hero;
}
//direkte übergabe des pointer an andere HERO pointer
void create_battle_startup()
{
HERO* hero0 = create_hero();
HERO* hero1 = create_hero();
HERO* hero2 = create_hero();
MONSTER* monster0 = create_enemies();
MONSTER* monster1 = create_enemies();
MONSTER* monster2 = create_enemies();
var i = hero0.INIT; //hier entsteht das Problem
int j = hero0.INIT;
printf("i = %d, j = %d", (int)i, j);
// Free heroes
sys_free(hero0);
sys_free(hero1);
sys_free(hero2);
// Free monstaers
sys_free(monster0);
sys_free(monster1);
sys_free(monster2);
}
Best regards.

@3dgs_snake
yeah I get the same result out of the first code, but let me emphasize that you read out the value for hero0. hero0 is coincidentally the only struct which works... just try it out for "hero1" thats the case where the trouble starts.

MONSTER* monster1 = create_enemies();
MONSTER* monster2 = create_enemies();
int i=hero1.INIT;
}
its untested i dont have gamestudio installed rite now but hope it helpes you good luck.

I've included your code, but the desired effect was not achieved instead of this the program assign new INIT values:
(WATCHED VARIABLES)
i1 = hero0.INIT = 16 // right value
i2 = hero1.INIT = 16 // wrong value (before = 408)
i3 = hero2.INIT = 19 // wrong value (before = 411)
for comparison //these are the desired values
1. hero = 16;
2. hero = 12;
2. hero = 15;

have you try "return &hero;" ? and does both examples give that result?
int hero_order[3] = {0,1,2};
int cur_hr = 0;
HERO* create_hero()
{
HERO* hero = malloc(sizeof(HERO));
if(hero)
{
int cur_hero_order=hero_order[cur_hr];
cur_hr+=1;
switch (cur_hero_order)
{
case 0:
{
hero.INIT=16;
return hero;//or return &hero
}
case 1:
{
hero.INIT=12;
return hero;//or return &hero
}
case 2:
{
hero.INIT=15;
return hero;//or return &hero
}
}
}
return NULL;
}

Have you tried changing the struct entry 'INIT' to something else? As a test...
Say for example H_INIT?
Just in case INIT is a "secret" reserved word or something?
