menu - 如何从屏幕设置位置菜单？

Question

如何使用通常的菜单查找将我的菜单 Sprites 设置在屏幕中央

CCSize 大小 = CCDirector::sharedDirector()->getWinSize(); 精灵->setPosition(ccp(size.width, size.height));

请帮我解决（ccp（？，？））

Sprites：开始、选项、退出游戏菜单

#include "MenuScene.h"
#include "cocos2d.h"

using namespace cocos2d;

CCSprite *car;

CCScene* MenuScene::scene()
{
CCScene *scene = CCScene::create();
MenuScene *layer = MenuScene::create();
scene->addChild(layer);

return scene;
}


// on "init" you need to initialize your instance
bool MenuScene::init()
{

// 1. super init first
if ( !CCLayer::init() )
{
    return false;
}
this->setTouchEnabled(true);
//this->schedule( schedule_selector(MenuScene::update) );

CCSize winSize = CCDirector::sharedDirector()->getWinSize();
CCSize size = CCDirector::sharedDirector()->getWinSize();
CCSize visibleSize = CCDirector::sharedDirector()->getVisibleSize();
CCPoint origin = CCDirector::sharedDirector()->getVisibleOrigin();


// add a "close" icon to exit the progress. it's an autorelease object
//    CCMenuItemImage *pCloseItem = CCMenuItemImage::create(
//                                        "CloseNormal.png",

Answer 1

如果您希望将菜单定位在屏幕的中心，您必须在 ccl 中提供中心坐标

   sprite ->setPosition(ccp(size.width/2, size.height/2));

Answer 2

首先你得到窗口大小......

CGSize Window_size=[[CCDirector sharedDirector]winSize];

现在在 CCMenu 中设置 CCMenuItem 的位置...

CCMenuItem *Minus_Menu_item = [CCMenuItemImage itemWithNormalImage:@"ButtonMinus.png" selectedImage:@"ButtonMinus.png" disabledImage:@"ButtonNum1.png" target:self selector:@selector(Minus_Button:)];
Minus_Menu_item.position=ccp(180, 200);
Menu_Minus=[CCMenu menuWithItems:Minus_Menu_item, nil];
Menu_Minus.position = CGPointZero;
[self addChild:Menu_Minus];
