我编辑了我的原始消息,以完全按原样包含我的代码。很抱歉给您带来麻烦。
这是我尝试使用指向我添加到项目中的类的指针的地方:
#ifndef MYAPP_DivGameLayer_h
#define MYAPP_DivGameLayer_h
// When you import this file, you import all the cocos2d classes
#include "cocos2d.h"
#include "Box2D.h"
#include "DivBall.h"
#define PTM_RATIO 32
#define GRAVITY -10.0f
#define VELOCITY_ITERS 8
#define POSITION_ITERS 1
#define BALLS_COUNT 2
class DivGameLayer : public cocos2d::CCLayer {
public:
~DivGameLayer();
DivGameLayer();
// returns a Scene that contains the layer as the only child
static cocos2d::CCScene* scene();
// functions for handling user input touches
virtual void ccTouchesEnded(cocos2d::CCSet* touches, cocos2d::CCEvent* event);
// game update loop function
void update(float dt);
private:
// CONSTANTS
float SCREEN_WIDTH;
float SCREEN_HEIGHT;
b2World* world; // the game's world
DivBall* balls; // balls
int next; // pointer to next ball
// initialize the game's world
void initWorld();
// initialize balls
void initBalls();
};
#endif
这是我的 DivBall 头文件:
#ifndef MYAPP_DivBall_h
#define MYAPP_DivBall_h
#include "DivGameLayer.h"
#define PATH "ball.png"
#define DENSITY 0.25f
#define FRICTION 0.1f
#define RESTITUTION 0.7f
class DivBall : public cocos2d::CCSprite {
public:
~DivBall();
DivBall(DivGameLayer layer, b2World* world, cocos2d::CCPoint location, float Vx, float Vy, float omega);
private:
DivBall();
b2Body* body;
};
#endif
这是 DivBall.cpp:
#include "DivBall.h"
#include "SimpleAudioEngine.h"
using namespace cocos2d;
using namespace CocosDenshion;
// defualt CTOR
DivBall::DivBall()
{
}
// CTOR
DivBall::DivBall(DivGameLayer layer, b2World* world, CCPoint location, float Vx, float Vy, float omega)
{
CCSprite *sprite = CCSprite::create(PATH);
sprite->setPosition( CCPointMake(location.x, location.y) );
layer->addChild(sprite);
// Define the dynamic body.
b2BodyDef bodyDef;
bodyDef.type = b2_dynamicBody;
bodyDef.position.Set(location.x/PTM_RATIO, location.y/PTM_RATIO);
bodyDef.userData = sprite;
b2Body *body = world->CreateBody(&bodyDef);
// Define a circle shape for our dynamic body.
b2CircleShape circle;
circle.m_radius = (sprite->getContentSize().width/2.0f)/PTM_RATIO;
// Define the dynamic body fixture.
b2FixtureDef fixtureDef;
fixtureDef.shape = &circle;
fixtureDef.density = DENSITY;
fixtureDef.friction = FRICTION;
fixtureDef.restitution = RESTITUTION;
body->CreateFixture(&fixtureDef);
// set velocity
body->SetLinearVelocity(b2Vec2(Vx/PTM_RATIO, Vy/PTM_RATIO));
body->SetAngularVelocity(omega);
}
// DCTOR
DivBall::~DivBall()
{
// nothing...
}
我在 GameLayer 中得到一个编译错误:未知类型名称 Ball。
抱歉不清楚。
