Is it possible to have 2 void functions to send arguements to a third function one each from those 2 functions ?
Yes, It's possible, Why do you think it is not possible?
Online Sample:
#include<iostream>
void doSomething(int &i)
{
i = 10;
}
void doSomethingMore(int &j)
{
j = 20;
}
void FinalDoSomething(const int i, const int j, int &k)
{
k = i + j;
}
int main()
{
int i = 0;
doSomething(i);
int j = 0;
doSomethingMore(j);
int k = 0;
FinalDoSomething(i,j,k);
std::cout<<k;
return 0;
}
You could have a method between that calls. This function stores the first call value into a member and on the second call it calls the function you want to pass the two parameters (using the previously passed one + the member

i don't know why function don't call when i clicked the label
You is not passed an argument in the calling function
CC_CALLBACK_1(MainMenuScene::goPlayScene, this)
You need either remove the Ref* pSender from void MainMenuScene::goPlayScene() or add an your sender in CC_CALLBACK_1(MainMenuScene::goPlayScene, this) after this.

and nothing no color in the background , why ?
im working on windows with VC 2012
I think your color is too dark. Try changing the values to (255,25,255,255) and check the result.
I created a sample project (in Beta 2), and only changed these lines:
.h:
class HelloWorld : public cocos2d::LayerColor
.cpp:
if( !LayerColor::initWithColor(Color4B(255,255,255,255)) )
The result is a white background.
I cleaned up and updated your code (I use cocos2dx 2.2.1) and I could change the layer's color to red.

I am somewhat new to C++ programming and to Cocos2d-x and I am having some trouble with my first Cocos2d-x game. I am literally just trying to simulate gravity and update the player's position based on that. I am running Xcode 4.6.1 and for some reason I keep getting a BAD_ACCESS exception after one run (if I restart it seems to work). It happens at libobjc.A.dylib`objc_release. I have tried doing an allexceptions breakpoint and it breaks at a memory address in the dylib. This only happened after I added a velocity variable to my Player class, so maybe I am not properly allocating pointers and the such? Here are the relevant classes I believe.
#include "cocos2d.h"
using namespace cocos2d;
class Player : public Sprite{
private:
Point velocity;
public:
static Player* create(const char *filename);
void update(float delta);
void setVelocity(const Point &v);
const Point& getVelocity() const;
~Player();
};
#include "Player.h"
USING_NS_CC;
using namespace cocos2d;
Player::~Player(){
}
Player* Player::create(const char *filename){
Player* self = (Player *) Sprite::create(filename);
self->setVelocity(Point::ZERO);
return self;
}
void Player::update(float delta){
log("In player update");
Point gravity = Point(0.0, -450.0);
Point gravityStep = gravity * delta;
this->setVelocity(this->getVelocity() + gravityStep);
log("Velocity after setting: %f", getVelocity().y);
Point stepVelocity = this->getVelocity() * delta;
this->setPosition(this->getPosition() + stepVelocity);
log("Position after setting: %f, %f", getPosition().x, getPosition().y);
}
void Player::setVelocity(const Point &v){
this->velocity = v;
}
const Point& Player::getVelocity() const
{
return this->velocity;
}
#include "GameLayer.h"
USING_NS_CC;
Scene* GameLayer::scene()
{
// 'scene' is an autorelease object
Scene *scene = Scene::create();
// 'layer' is an autorelease object
GameLayer *layer = GameLayer::create();
// add layer as a child to scene
scene->addChild(layer);
// return the scene
return scene;
}
GameLayer::~GameLayer(){
CC_SAFE_RELEASE(player);
CC_SAFE_RELEASE(map);
}
bool GameLayer::init()
{
if ( !Layer::init() )
{
return false;
}
LayerColor *blueSky = LayerColor::create(*new Color4B(100, 100, 250, 255));
this->addChild(blueSky);
map = TMXTiledMap::create("level1.tmx");
this->addChild(map);
player = Player::create("koalio_stand.png");
player->setPosition(Point(100,50));
map->addChild(player, 15);
setKeyboardEnabled(true);
this->scheduleUpdate();
return true;
}
void GameLayer::update(float dt){
player->update(dt);
}
EDIT: So I figured out that the constructor of player was the problem. However, I'm wondering if it is kosher to do the following (since Player inherits from Sprite) to copy the Sprite function:
Sprite* Sprite::create(const char *filename)
{
Sprite *sprite = new Sprite();
if (sprite && sprite->initWithFile(filename))
{
sprite->autorelease();
return sprite;
}
CC_SAFE_DELETE(sprite);
return NULL;
}
and have the Player function be:
Player* Player::create(const char *filename){
Player *sprite = new Player();
if (sprite && sprite->initWithFile(filename))
{
sprite->setVelocity(Point::ZERO);
sprite->autorelease();
return sprite;
}
CC_SAFE_DELETE(sprite);
return NULL;
}
Or perhaps is there a cleaner way to call the create of Sprite, but to create a Player object which inherits and sets the velocity?
I'm trying to port my iPhone app to windows 8, I have a problem with this line (it's objective-c) :
[self schedule:#selector(fire:)];
The equivalent on c++ should be :
this->schedule(schedule_selector(AirScene::fire));
Where AirScene is the name of my class, but I have this error returning by Visual Studio 2012 :
error C2064: term does not evaluate to a function taking 1 arguments
So, in other words the function schedule(selector) is not found. It's strange because I have no problem with unschedule method, do you have any idea please ?

The version of cocos 2d which is used for windows 8 template is an old version, so the good way to schedule a selector is this one :
CCScheduler::sharedScheduler()->scheduleSelector(schedule_selector(AirScene::fire), this, 0, false);
I 've declared some classes in my cocos2dx program, and I 've set some values for their member variables, but after each time the program loops ( the main loop of the CCDirector ), all of their values have been removed!
I want it class to save its next scene that should be replaced or pushed when the scene should be replaced (as you can see in the code, after 2 second, the introPage class calls a function "IntoPageDone" and the scene should be replaced )and I 've set a variable named nextScene for the next Scene, but after each loop, its value changes into NULL.
plz help me with this problem, and also is there some better ways to handling the scenes and changes of them??
tnx a lot!
StartingPage is a class which is inherited from CCLayerColor.
Here is CoCoGui.h file:
#ifndef _COCOGUI_H_
#define _COCOGUI_H_
#include "StartingPage.h"
#include "IntroPage.h"
using namespace cocos2d;
class CoCoGui : public CCLayerColor{
public:
CoCoGui();
virtual ~CoCoGui(void);
virtual bool init();
static CCScene* scene();
CREATE_FUNC(CoCoGui);
private:
IntroPage * introPage;
StartingPage * startingPage;
void onEnterTransitionDidFinish();
};
#endif /* COCOGUI_H */
And this is CoCoGui.cpp file:
#include "CoCoGui.h"
#include <iostream>
using namespace std;
CCScene* CoCoGui::scene(){
CCScene *scene = CCScene::create();
CoCoGui *layer = CoCoGui::create();
scene->addChild(layer);
return scene;
}
CoCoGui::CoCoGui ( )
{
this->startingPage = new StartingPage ( );
this->introPage = new IntroPage ( );
}
CoCoGui::~CoCoGui(void)
{
delete introPage;
delete startingPage;
}
bool CoCoGui::init ( ){
if ( !CCLayerColor::initWithColor ( ccc4 (100,100,100,255) ) ){
return false;
}
return true;
}
void CoCoGui::onEnterTransitionDidFinish ( ){
this->introPage->setNextScene ( StartingPage::scene( ) );
CCScene * scene = NULL;
scene = IntroPage::scene();
CCTransitionFade * trans = CCTransitionFade::create( 0.4f, scene , ccBLACK);
CCDirector::sharedDirector()->pushScene(trans);
cout << "step" << endl;
}
This is introPage.h file:
#ifndef INTROPAGE_H_
#define INTROPAGE_H_
#include "cocos2d.h"
#include "StartingPage.h"
using namespace cocos2d;
class IntroPage: public CCLayerColor {

IntroPage ( );
virtual ~IntroPage();
static CCScene* scene();
bool init();
void intoPageDone();
CREATE_FUNC(IntroPage);
CC_SYNTHESIZE_READONLY(CCLabelTTF*, _label, Label);
CCScene * getNextScene( );
void setNextScene ( CCScene * nScene );
private:
CCScene * nextScene;
};
#endif /* INTROPAGE_H_ */
And also IntroPage.cpp:
#include "IntroPage.h"
IntroPage::IntroPage( CCScene * nextScene ) {
this->introPageDone = false;
this->setNextScene ( nextScene );
}
IntroPage::IntroPage( ){
}
IntroPage::~IntroPage() {
}
void IntroPage::setNextScene ( CCScene * nScene ){
this->nextScene = nScene;
}
CCScene* IntroPage::scene(){
CCScene *scene = CCScene::create();
IntroPage *layer = IntroPage::create();
scene->addChild(layer);
return scene;
}
bool IntroPage::init() {
if (CCLayerColor::initWithColor (ccc4(0, 0, 0, 255) )) {
this->runAction(
CCSequence::actions(CCDelayTime::actionWithDuration(2),
CCCallFunc::actionWithTarget(this,
callfunc_selector(IntroPage::intoPageDone)),
NULL));
return true;
}
return false;
}
void IntroPage::intoPageDone() {
this->introPageDone = true;
CCDirector::sharedDirector( )->popScene( );
CCDirector::sharedDirector( )->pushScene( this->nextScene );
}
Finally I found the answer!
We should use static variable, so they won't destructed after main loop
