c++ struct does not name a type error

Question

I get the following errors when trying to compile this code, why?

"game.h:48:42: error: ‘player’ does not name a type

game.h:48:50: error: ISO C++ forbids declaration of ‘enemies’ with no type [-fpermissive] "

Line 48 is the function "fillMap" btw

//game.h

#ifndef GAME_H
#define GAME_H

//CONSTANTS AND TEMPLATES

const int LEN = 40;

struct player
{
   char name[LEN]; //name of character
   char symbol; //character representing player on map
   int posx; // x position on map
   int posy; // y position on map
   bool alive; // Is the player alive
   double damage; // Player attacking power
   double health; // Player health
};

enum direction {LEFT, RIGHT, UP, DOWN};

//PROTOTYPES

//move amount specified in position structure
void moveAmount(player& pl, int posx, int posy);

//move to specified position on map
void moveTo(player& pl, int posx, int posy);

//one player attacking other
//returns whether attack was successfull
bool attack(const player & atacker, player & target);

//one player attacking a direction on the map, epl is a pointer to an array of enemies           players
//returns whether attack was sucessfull
bool attack(const player & pl, direction, player* epl);

//Check if player is dead, to be called inside attack function
inline bool isDead(const player& pl){
    return pl.health <= 0 ? 1 : 0;
}

//Remove player from map if he is dead
void kill(player& pl);

//Initialize map
void fillMap(const player& player, const player* enemies, int mapWidth, int mapHeigth);

//Display map
void displayMap(const int mapWidth, const int mapHeigth);

#endif

Answer 1

The problem is on this line:

void fillMap(const player& player, const player* enemies, int mapWidth, int mapHeigth);

Since you declare player as a parameter, it remains in scope for the entire forward declaration. Therefore, its name shadows the type name player: inside the forward declaration of fillMap, player refers to the first parameter, not to the player type.

Rename it to pl to fix this problem:

void fillMap(const player& pl, const player* enemies, int mapWidth, int mapHeigth);

Answer 2

Because player isn't a type; struct player is.
