Cocos2d-x 3.2 大富翁遊戲項目開發-第十七部分 Toast提示框，cocos2d-xtoast

在繳納過路費時，在角色附近顯示減少的資金數，收到過路費的角色顯示增加的資金數，效果

網上有不少這方面的資料，我拿來稍微修改了一下

寫一個CocosToast多士類

#ifndef __CocosToast_H__#define __CocosToast_H__#include "cocos2d.h"#include "cocos-ext.h"USING_NS_CC;using namespace std;class CocosToast :public LayerColor{public:CocosToast(void);~CocosToast(void);static void createToast(Node* node,const std::string& msg,const float& time,Vec2 point);void removeToast(Node* node);};#endif

#include "CocosToast.h"參數node：添加該Toast  layer的父節點msg：顯示的資訊time：toast顯示的時間長短point：toast顯示的位置座標void CocosToast::createToast(cocos2d::Node *node, const std::string &msg, const float &time,Vec2 point){   //建立顯示資訊的label    auto label = Label::createWithSystemFont(msg.c_str(), "Arial", 20);    label->setColor(Color3B::WHITE);    label->ignoreAnchorPointForPosition(false);    label->setAnchorPoint(Vec2::ANCHOR_MIDDLE);       //toast的layer層    auto layer = LayerColor::create(Color4B(100,100,100,255));    layer->ignoreAnchorPointForPosition(false);    layer->setAnchorPoint(Vec2::ANCHOR_MIDDLE);    layer->setContentSize(label->getContentSize() + Size(20,15));    node->addChild(layer);    node->addChild(label);    layer->setPosition(point);    label->setPosition(layer->getPosition());    //toast顯示時的動作，先由下而上，再由上而下，回到point的位置，動作結束時，把toast從父節點清除    auto seq1 = Sequence::create(FadeIn::create(time/5), DelayTime::create(time/5*1.5),FadeOut::create(time/5*2.5),CallFuncN::create(layer,callfuncN_selector(CocosToast::removeToast)),NULL);    auto seq2 = Sequence::create(EaseSineIn::create(MoveBy::create(time/5, Vec2(0,50))),DelayTime::create(time/5*2),EaseSineOut::create(MoveBy::create(time/3, Vec2(0,-50))), NULL);    auto spawn = Spawn::create(seq1, seq2, NULL);    auto action = Repeat::create(spawn,1);    layer->setOpacity(0);    label->setOpacity(0);    layer->runAction(action);    label->runAction(action->clone());}void CocosToast::removeToast(Node* node){    this->removeFromParentAndCleanup(true);}CocosToast::CocosToast(void){}CocosToast::~CocosToast(void){}

現在修改一下GameBaseScene的payTolls方法

void GameBaseScene::payTolls(int payTag,float x,float y ,int playerTag){…………switch(playerTag){  case PLAYER_1_TAG:  {    int retMoney = displayArea(x,y,player1,player2_building_1_tiledID,player2_building_2_tiledID,player2_building_3_tiledID);    refreshMoneyLabel(landOwner,money + retMoney);    refreshMoneyLabel(player1,-(money + retMoney));   //Toast顯示相應角色增加和減少的資金數    CocosToast::createToast(this, String::createWithFormat("+%d",money + retMoney)->getCString(), TOAST_SHOW_TIME,landOwner->getPosition());    CocosToast::createToast(this, String::createWithFormat("-%d",money + retMoney)->getCString(), TOAST_SHOW_TIME,player1->getPosition());   //注意當是第一角色時，延時TOAST_SHOW_TIME秒後發送繼續行走訊息，避免toast顯示過於頻繁   scheduleOnce(schedule_selector( GameBaseScene::sendMSGPickOneToGO),TOAST_SHOW_TIME);   break;  }  case PLAYER_2_TAG:   {    int retMoney = displayArea(x,y,player2,player1_building_1_tiledID,player1_building_2_tiledID,player1_building_3_tiledID);    refreshMoneyLabel(landOwner,money + retMoney);    refreshMoneyLabel(player2,-(money + retMoney));    CocosToast::createToast(this, String::createWithFormat("+%d",money + retMoney)->getCString(), TOAST_SHOW_TIME,landOwner->getPosition());    CocosToast::createToast(this, String::createWithFormat("-%d",money + retMoney)->getCString(), TOAST_SHOW_TIME,player2->getPosition());    NotificationCenter::getInstance()->postNotification(MSG_PICKONE_TOGO,String::createWithFormat("%d",MSG_PICKONE_TOGO_TAG));    break;  }}……………….}
