include/TestBullet.h:12: error: expected constructor, destructor, or type conver
sion before '(' token
I hate C++ error messages... lol ^^
Basically, I'm following what was written in this post to try to create a factory class for bullets so they can be instantiated from a string, which will be parsed from an xml file, because I don't want to have a function with a switch for all of the classes because that looks ugly.
Here is my TestBullet.h:
#pragma once
#include "Bullet.h"
#include "BulletFactory.h"
class TestBullet : public Bullet {
public:
void init(BulletData& bulletData);
void update();
};
REGISTER_BULLET(TestBullet); <-- line 12
And my BulletFactory.h:
#pragma once
#include <string>
#include <map>
#include "Bullet.h"
#define REGISTER_BULLET(NAME) BulletFactory::reg<NAME>(#NAME)
#define REGISTER_BULLET_ALT(NAME, CLASS) BulletFactory::reg<CLASS>(NAME)
template<typename T> Bullet * create() { return new T; }
struct BulletFactory {
typedef std::map<std::string, Bullet*(*)()> bulletMapType;
static bulletMapType map;
static Bullet * createInstance(char* s) {
std::string str(s);
bulletMapType::iterator it = map.find(str);
if(it == map.end())
return 0;
return it->second();
}
template<typename T>
static void reg(std::string& s) {
map.insert(std::make_pair(s, &create<T>));
}
};
Thanks in advance.
