我有两个 C++ 类波纹管。我想从 LHSceneSubclass 获取 LHContactInfo 属性,但我什么也得不到。那么我该怎么做呢?
#ifndef __LEVELHELPER_API_CONTACT_INFO_H__
#define __LEVELHELPER_API_CONTACT_INFO_H__
#include "LHConfig.h"
#if LH_USE_BOX2D
#include "cocos2d.h"
class b2Contact;
using namespace cocos2d;
class LHContactInfo
{
public:
LHContactInfo();
virtual ~LHContactInfo();
Node* nodeA;
Node* nodeB;
std::string nodeAShapeName;
std::string nodeBShapeName;
int nodeAShapeID;
int nodeBShapeID;
Point contactPoint;
float impulse;
b2Contact* box2dContact;
};
#endif
#endif //__LEVELHELPER_API_CONTACT_INFO_H__
#include "LHContactInfo.h"
#if LH_USE_BOX2D
#include "Box2d/Box2d.h"
LHContactInfo::LHContactInfo(){
nodeA = NULL;
nodeB = NULL;
box2dContact = NULL;
}
LHContactInfo::~LHContactInfo(){
nodeA = NULL;
nodeB = NULL;
box2dContact = NULL;
}
#endif
#ifndef __LH_SCENE_SUBCLASS_H__
#define __LH_SCENE_SUBCLASS_H__
#include "cocos2d.h"
#include "LevelHelper2API.h"
class LHContactInfo;
class LHSceneSubclass : public LHScene
{
public:
static cocos2d::Scene* createScene();
LHSceneSubclass();
virtual ~LHSceneSubclass();
bool initWithContentOfFile(const std::string& plistLevelFile);
virtual bool shouldDisableContactBetweenNodes(Node* nodeA, Node* nodeB);
virtual void didBeginContact(const LHContactInfo& contact);
virtual void didEndContact(const LHContactInfo& contact);
};
#endif // __LH_SCENE_SUBCLASS_H__
//file.cpp
void LHSceneSubclass::didBeginContact(const LHContactInfo& contact){
if(contact.nodeA->getName() == "box1"){// error invalid use of incomplete type 'const class
LHContactInfo'
}
}
void LHSceneSubclass::didEndContact(const LHContactInfo& contact){
CCLOG("DIDENDCONTACT...\n");
}
我想在 didBeginContact 函数中使用 LHContactInfo 中的contact.nodeA,但编译错误->错误无效使用不完整类型'const class LHContactInfo'
注意:: - 使用 android NDK 10c 编译
