Constructeur ne peut pas trouver la définition appropriée, et 100 autres erreurs de nulle part?

Question

J'essaye d'écrire un emballage pour la physique de balle pour l'implémenter dans mon cadre de jeu.

J'ai 3 classes, mDebugDraw est une implémentation du dessin de mise au point de balle.

mRigidBody est un contenant pour le corps rigide de la balle.

World est un conteneur pour le monde des balles. Je ai ~ 100 erreurs dans Visual Studio, et presque tous viennent d'où j'essaye de créer mRigidBodies, les erreurs sont "ne peut pas convertir de la liste d'initialisation à mRigidBody", "pas de constructeur approprié disponible", ainsi que des étranges comme "mRigidBody :: mRigidBody (std :: string) fonction membre est déjà défini ou déclaré", ce qui n'est pas une fonction que j'ai implémentée.

world.h contient les définitions pour les trois classes:

#pragma once 
#include <btBulletDynamicsCommon.h> 
#include <BulletCollision\CollisionShapes\btBoxShape.h> 
#include <GL/glew.h> 
#include "LinearMath\btIDebugDraw.h" 
#include <vector> 
#include <glm\vec3.hpp> 
#include <iostream> 
#include <map> 

class mDebugDraw : public btIDebugDraw 
{ 
private: 
    int debugMode; 
public: 
    mDebugDraw(); 
    virtual ~mDebugDraw(); 

    struct mLine 
    { 
     glm::vec3 from; 
     glm::vec3 to; 
     glm::vec3 color; 

     mLine(const glm::vec3 ifrom, const glm::vec3 ito, glm::vec3 _color) 
     { 
      from = ifrom; 
      to = ito; 
      color = _color; 

     } 
    }; 

    std::vector<mLine> lines; 

    struct mColor 
    { 
     glm::vec3 col; 

     mColor(const glm::vec3 c) 
     { 
      col = c; 
     } 
    }; 

    std::vector<mColor> colors; 

    GLuint vao; 
    GLuint vbo[2]; 

    virtual void drawLine(const btVector3& from, const btVector3& to, const btVector3& color);

    virtual int getDebugMode() const; 

    virtual void drawTriangle(const btVector3 & a, const btVector3 & b, const btVector3 & c, const btVector3 & color, btScalar alpha) {} 

    void reportErrorWarning(const char * warningString) { std::cout << "Physics debugger warning: " << warningString << std::endl; } 

    std::vector<mLine> & GetLines() { return lines; } 

    void draw(); 

    void clean(); 
}; 

class mRigidBody 
{ 
public: 
    mRigidBody(std::string name, World::shapeTypes type, glm::vec3 extent, glm::vec3 startposition); 
    mRigidBody(std::string name, World::shapeTypes type, glm::vec3 extent, glm::vec3 startPosition, float mass, float friction, float restitution); 
    void setPosition(glm::vec3 _position); 
    void setMass(float _mass); 
    void setRestitution(float _restitution); 
    void setFriction(float _friction); 
    std::string getName() const { return name; } 
    btCollisionShape* getShape() { return mShape; } 
    btRigidBody* getBody() { return rigidBody; } 
    int getIndex() const { return index; } 
private: 
    btCollisionShape* mShape; 
    btRigidBody* rigidBody; 
    std::string name; 
    int index; 
    //btDefaultMotionState * mMotionState; 
}; 

class World 
{ 

protected: 
    World(); 
public: 
    enum shapeTypes 
    { 
     sphere, 
     cube, 
     capsule 
    }; 
    static World * gameWorld(); 
    void init(); 
    btDiscreteDynamicsWorld* physicsWorld; 
    std::vector<btBoxShape> hitboxes; 
    mDebugDraw debugDrawer; 
    void drawWireframe(); 
    mRigidBody* getRigidBody(std::string name) const; 
    void addRigidBody(mRigidBody* _body, std::string _name); 
    std::map<std::string, mRigidBody *> getMap() { return mRigidBodies; } 
private: 
    static World *mInstance; 
    std::map<std::string, mRigidBody *> mRigidBodies; 
}; 

la plupart des erreurs proviennent de ces deux lignes world.h, où je suis définissant les deux constructeurs.

mRigidBody(std::string name, World::shapeTypes type, glm::vec3 extent, glm::vec3 startposition); 
mRigidBody(std::string name, World::shapeTypes type, glm::vec3 extent, glm::vec3 startPosition, float mass, float friction, float restitution); 

Voici la liste complète des erreurs.

Merci d'avance pour toute aide, j'ai lutté avec cela pendant un jour maintenant.

Answer 1

World est utilisé avant d'être déclaré. Dans la définition des constructeurs de mRigidBody, vous faites référence à World::shapeTypes mais World n'est défini que plus tard dans le fichier. Essayez de placer la définition de World avant mRigidBody. Vous devrez peut-être forward declaremRigidBody avant de définir World.

Answer 2

Insérer une ligne avant la définition de classe mRigidBody:

class World; 
class mRigidBody
