Problems using textures in classes

[C0dedSurvivor]

I didn't even fully understand what the problem is. It was fixed when I commented out the texture and sprite declaration, but I need those for what I am using it for. The code I used was:

Main:

enemy enemies[4];

int main(){
   for (int a = 0; a < enemyListL; a++){
      enemies[a].name = "dead";
      if (!enemies[a].texture.create(32, 32)){}
   }
   enemies[0].sprite.setPosition(50, 50);

   generateEnemy(enemies, "link", 15);
}

Class:

#include <SFML/Graphics.hpp>

using namespace sf;

const int enemyListL = 5;

string enemiesNames[enemyListL] = { "link", "wyrm", "armored wyrm", "glitching wyrm", "evil guard" };

//health, pAttack, aAttack, pDefense, aDefense, speed, luck
int enemyBaseStat[7][enemyListL] = { 5, 5, 5, 5, 5, 5, 5};

class enemy{
public:
   string name;
   int health;
   int level;
   int pAtk;
   int aAtk;
   int pDef;
   int aDef;
   int speed;
   int luck;
   Texture texture;
   Sprite sprite;
   enemy(){               //This is the line it points to with the error
   }
};

int takeDamageDisk(Disks disk, enemy enemy1){
   srand(time(NULL));
   return ((disk.damage * 2) / (enemy1.aDef)) * ((rand() % 15) + 91) / 100;
}

void generateEnemy(enemy enemiesT[4], string name, int level){
   for (int a = 0; a < 4; a++){
      if (enemiesT[a].name == "dead"){
         for (int b = 0; b < enemyListL; b++){
            if (name == enemiesNames){
               enemiesT[a].level = level;
               srand(time(NULL));
               enemiesT[a].health = enemyBaseStat[0] * level + (enemyBaseStat[0] * level * (((rand() % 30) - 15) + 100) / 100);
               srand(rand() ^ time(NULL));
               enemiesT[a].pAtk = enemyBaseStat[1] * level + (enemyBaseStat[1] * level * (((rand() % 30) - 15) + 100) / 100);
               srand(rand() * time(NULL));
               enemiesT[a].aAtk = enemyBaseStat[2] * level + (enemyBaseStat[2] * level * (((rand() % 30) - 15) + 100) / 100);
               srand(rand() ^ time(NULL));
               enemiesT[a].pDef = enemyBaseStat[3] * level + (enemyBaseStat[3] * level * (((rand() % 30) - 15) + 100) / 100);
               srand(rand() * time(NULL));
               enemiesT[a].aDef = enemyBaseStat[4] * level + (enemyBaseStat[4] * level * (((rand() % 30) - 15) + 100) / 100);
               srand(rand() ^ time(NULL));
               enemiesT[a].speed = enemyBaseStat[5] * level + (enemyBaseStat[5] * level * (((rand() % 30) - 15) + 100) / 100);
               srand(rand() * time(NULL));
               enemiesT[a].luck = enemyBaseStat[6] * level + (enemyBaseStat[6] * level * (((rand() % 10) - 5) + 100) / 100);
               sf::Image image;
               image.loadFromFile("Images\Enemies\\" + name + ".png");
               enemiesT[a].texture.update(image);
               enemiesT[a].sprite.setTexture(enemiesT[a].texture);
            }
         }
      }
   }
}


The window compiles correctly but crashes immediately after launch, before the window can even register.

The error is this:
Unhandled exception at 0x777522D2 (ntdll.dll) in RPGFramework.exe: 0xC0000005: Access violation writing location 0x00000004.

Did you use a debugger to narrow down the line in which the error occurs (stacktrace, where it gets called from)?

Apart of that, I'm not sure you should use an sf::Texture as a value-member of your enemy class. It will get loaded multiple times redundantly and if you're not careful, it will get copied, which is bad for performance and memory footprint.

As far as I can find, that is where the stacktrace starts. As for whether I should do this, I can't find any other way to check the name of a texture to attach it to a sprite. I don't want to have to create separate classes for each enemy. As you can see from the second part of the code, I am attaching the texture by comparing the file name to the name of the enemy. If there is a way to check the the name of a texture, compare it to the name of an enemy and attach it if it matches, that would be great. But I don't know ow to do that.

Globals make me cry 

I think I can point you in the direction of the source of your error:

const int enemyListL = 5;
// ...
enemy enemies[4];
// ...
for (int a = 0; a < enemyListL; a++){
  enemies[a].name = "dead";
  if (!enemies[a].texture.create(32, 32)){}
}

Thanks for your help, because it seems SFML has the same problem you have, it hates being Global. As soon as a moved it into being a non-global texture, it fixed.

Did you not see the error in the code I posted?
