Making a button perform an action

cocos2d-x C++
#1

Using cocos2d-x V3.17, I want to make my button move up when it’s clicked, in the following code is two separate button codes, I have asterisk-coated the line which I assume the action should occur to, but expectedly, the name of the button isn’t recognised in the section. How do I make it recognised within the curly braces?


void DEL1::DEL1HEL(cocos2d::Ref *pSender)
{

	CocosDenshion::SimpleAudioEngine::getInstance()->playEffect("Button clicked (2).mp3");

	DEL1H = Sprite::create("HelpDClick.png");
	this->addChild(DEL1H);
	DEL1H->setPosition(Point(730, 1200));
	DEL1H->setScale(1.5);


	auto DL1HMM = MoveBy::create(1.4, Point(0, -740));

	DEL1H->runAction(DL1HMM);




	CCLOG("Help");


	auto DEL1ExitHelpMenu1 = MenuItemImage::create("GOTIT.png", "GOTIT.png", CC_CALLBACK_1(DEL1::DEL1HELEXI, this));
	DEL1ExitHelpMenu1->setPosition(Point(820, 1200));
	DEL1ExitHelpMenu1->setScale(0.8);

	auto DL1HEE = MoveBy::create(1.4, Point(0, -1060));

	DEL1ExitHelpMenu1->runAction(DL1HEE);



	auto *DEL1Hmenu = Menu::create(DEL1ExitHelpMenu1, NULL);
	DEL1Hmenu->setPosition(Point(0, 0));
	this->addChild(DEL1Hmenu);



}
void DEL1::DEL1HELEXI(cocos2d::Ref *pSender)
{

		CocosDenshion::SimpleAudioEngine::getInstance()->playEffect("Button clicked (7).mp3");
		
		***auto DL1HUE = MoveBy::create(1.4, Point(0, 1060));***
               ***DEL1ExitHelpMenu1->runAction(DL1HUE);***


		auto DL1HLL = MoveBy::create(1, Point(0, 1200));

		DEL1H->runAction(DL1HLL);



		CCLOG("Remove advice");

Look at where those objects defined… you define them out of scope of where you try to act upon them.

#3

I have attempted severed definitition combinations but this hasn’t worked, where should I define it? I am guessing within the init method, but the way I am doing it proves innefective

#4

your header file, perhaps?

#5

apologies for not specifying, this was already in the header

#6

That’s not defining. Post the whole header please.

DEL1 is short for destruction level 1

#pragma once

#include "cocos2d.h"

class DEL1 : public cocos2d::Scene
{
public:
	static cocos2d::Scene* createScene();

	virtual bool init();

	// a selector callback 
	void menuCloseCallback(cocos2d::Ref* pSender);
	
	// implement the "static create()" method manually
	CREATE_FUNC(DEL1);

	
	cocos2d::Sprite *DEL1B;
	cocos2d::Sprite *DEL1P;
	cocos2d::Sprite *DEL1H;
	
void DEL1HELEXI(Ref *pSender);
void DEL1HEL(Ref *pSender);
void DEL1EXI(Ref *pSender);
void DEL1RES(Ref *pSender);
void DEL1PAU(Ref *pSender);
void DEL1PLA(Ref *pSender);
};

I suggest you name classes, methods, variables more clearly.
For me DEL means delete.
Better name it DestructionLevel1
Or it’s hard for you type so much? :smile:

If someone else will help you with coding it will understand code more fast and easily.

Yeah, he PM’d me so I helped him out with a couple of problems. I suggested him to cover the basics of c++ before diving into cocos2d-x.

There are a lot of free books: http://iacs-courses.seas.harvard.edu/courses/cs207/resources/TIC2Vone.pdf

Not to mention videos all over the place.

I have a lot of c++ books. If you are in the U.S.A, I will ship you one.

in our PMing I thoroughly went over proof I have done so.

I have all I need c++ wise, now my main pure concern is physics as the UI is complete
