Cocos2d-x 3.2 大富翁游戏项目开发-第二十六部分 人物技能，cocos2d-x项目开发
本节主要是添加人物技能，技能包括
暴风骤雨：此技能可以把地块变成空白地块，
随心步：选择想走的步数，想走几步走几步
巧取豪夺：把对手的土地变成自己的
技能包含的信息：等级 和 耗费体力
等级共5级，每提高一个等级，需要耗费的体力值减10
暴风骤雨：初始耗费体力值70
随心步：初始耗费体力值50
巧取豪夺：初始耗费体力值100
1、添加技能SkillCard 类，包含了技能基本信息以及如何显示技能
其实现和前面讲解的股票 彩票 card类相似，不再累述
2、修改RicherPlayer类，添加技能相关属性及方法
RicherPlayer.h
//添加技能播放的动画
void addSkillAnimation();
CC_SYNTHESIZE(Vector<SpriteFrame*>, skill_rain_vector, Skill_rain_vector);
CC_SYNTHESIZE(Vector<SpriteFrame*>, skill_transfer_vector, Skill_transfer_vector);
CC_SYNTHESIZE(Animate* ,rain_skill,RainSkill);
CC_SYNTHESIZE(Animate* ,transfer_skill, Transfer_skill);
//存放技能等级信息
std::vector<int> skill_vector;
//存放角色停止走动后的位置
float stop_x;
float stop_y;
RicherPlayer.cpp
RicherPlayer::RicherPlayer()
{
......
//初始停留位置
stop_x = -100;
stop_y =0;
}
bool RicherPlayer::init(char* name, int tag,bool enemy,int money,int strength)
{
...................
//初始技能默认等级为1
skill_vector.push_back(1);
skill_vector.push_back(1);
skill_vector.push_back(1);
//添加技能动画相关
addSkillAnimation();
}
void RicherPlayer::addSkillAnimation()
{
..............
//包括暴风骤雨 、巧取豪夺 2个技能的动画
rain_skill =Animate::create(AnimationCache::getInstance()->getAnimation("rain_animation"));
transfer_skill = Animate::create(AnimationCache::getInstance()->getAnimation("transfer_animation"));
rain_skill->retain();
transfer_skill->retain();
}
3、添加技能菜单键
//在添加go按钮的时候同时添加技能按钮
voidGameBaseScene::addGoButton()
{
................
//技能按钮，在go按钮下发
skillMenuItemButton = MenuItemImage::create("images/skill_button_normal.png", "images/skill_button_pressed.png", this, menu_selector(GameBaseScene::goButtonCallback));
skillMenuItemButton->setPosition(ccp(tableStartPosition_x+2*tableWidth+20,tableStartPosition_y-tableHeight*6-80));
skillMenuItemButton->setTag(skillButtonTag);
menu->addChild(skillMenuItemButton);
//添加步数按钮，用于随心步技能
step1Button = MenuItemImage::create("images/step1_normal.png", "images/step1_pressed.png", this, menu_selector(GameBaseScene::goButtonCallback));
..........
step2Button = MenuItemImage::create("images/step2_normal.png", "images/step2_pressed.png", this, menu_selector(GameBaseScene::goButtonCallback));
............
step3Button = MenuItemImage::create("images/step3_normal.png", "images/step3_pressed.png", this, menu_selector(GameBaseScene::goButtonCallback));
..........
step4Button = MenuItemImage::create("images/step4_normal.png", "images/step4_pressed.png", this, menu_selector(GameBaseScene::goButtonCallback));
.........
step5Button = MenuItemImage::create("images/step5_normal.png", "images/step5_pressed.png", this, menu_selector(GameBaseScene::goButtonCallback));
.......
step6Button = MenuItemImage::create("images/step6_normal.png", "images/step6_pressed.png", this, menu_selector(GameBaseScene::goButtonCallback));
//暴风骤雨技能显示界面
skillStorm = SkillCard::createCardSprite(LanguageString::getInstance()->getLanguageString(RAIN),
LanguageString::getInstance()->getLanguageString(GRADE),
LanguageString::getInstance()->getLanguageString(LOST_STRENGTH),
LanguageString::getInstance()->getLanguageString(DOWN_GRADE) ,skillSpriteCardWidth,skillSpriteCardHeight,100,-130,skillStormTag,"images/thunderstorm.png");
addChild(skillStorm,50);
//随心步技能显示界面
skillStep = SkillCard::createCardSprite(LanguageString::getInstance()->getLanguageString(GOBY_HEART),
LanguageString::getInstance()->getLanguageString(GRADE),
LanguageString::getInstance()->getLanguageString(LOST_STRENGTH),
LanguageString::getInstance()->getLanguageString(GOBY_HEART_INFO) ,skillSpriteCardWidth,skillSpriteCardHeight,280,-130,skillStepTag,"images/skill_step.png");
addChild(skillStep,50);
//巧取豪夺显示界面
skillTransfer = SkillCard::createCardSprite(LanguageString::getInstance()->getLanguageString(YOURS_IS_MINE),
LanguageString::getInstance()->getLanguageString(GRADE),
LanguageString::getInstance()->getLanguageString(LOST_STRENGTH),
LanguageString::getInstance()->getLanguageString(YOURS_IS_MINE_INFO) ,skillSpriteCardWidth,skillSpriteCardHeight,460,-130,skillTransferTag,"images/skill_transfer.png");
addChild(skillTransfer,50);
//添加各个界面点击回调方法
skillStorm->setSkillButtonCallback(this,callfuncN_selector(GameBaseScene::skillClick));
skillStep->setSkillButtonCallback(this,callfuncN_selector(GameBaseScene::skillClick));
skillTransfer->setSkillButtonCallback(this,callfuncN_selector(GameBaseScene::skillClick));
//技能界面是否在显示
isSkillLayerShow = false;
//随心步步数按钮界面是否显示
isStepLayerShow = false;
}
4、显示或隐藏随心步步数按钮界面，显示或隐藏时播放旋转动画
voidGameBaseScene::showStepButton(bool show)
{
if(show)
{
//显示时变为可见
step1Button->setVisible(true);
step2Button->setVisible(true);
step3Button->setVisible(true);
step4Button->setVisible(true);
step5Button->setVisible(true);
step6Button->setVisible(true);
//顺时针依次播放动画
step2Button->runAction(RotateBy::create(stepSkillAnimaTime,60));
step3Button->runAction(RotateBy::create(2*stepSkillAnimaTime,120));
step4Button->runAction(RotateBy::create(3*stepSkillAnimaTime,180));
step5Button->runAction(RotateBy::create(4*stepSkillAnimaTime,240));
step6Button->runAction(RotateBy::create(5*stepSkillAnimaTime,300));
}else
{
//隐藏时相反
step2Button->runAction(RotateBy::create(stepSkillAnimaTime,-60));
step3Button->runAction(RotateBy::create(2*stepSkillAnimaTime,-120));
step4Button->runAction(RotateBy::create(3*stepSkillAnimaTime,-180));
step5Button->runAction(RotateBy::create(4*stepSkillAnimaTime,-240));
step6Button->runAction(RotateBy::create(5*stepSkillAnimaTime,-300));
step6Button->runAction(Sequence::create(RotateBy::create(5*stepSkillAnimaTime,-300),CallFunc::create([this](){
step1Button->setVisible(false);
step2Button->setVisible(false);
step3Button->setVisible(false);
step4Button->setVisible(false);
step5Button->setVisible(false);
step6Button->setVisible(false);
}
),NULL));
}
}
//技能界面点击相应函数
void GameBaseScene::skillClick(Node *pNode)
{
int tag = pNode->getTag();
if(tag == skillStormTag)
{
if(player1->stop_x< 0)
{
return;
}
//当点击暴风骤雨时，判断角色体力值是否满足技能耗费的体力值，如果满足 就播放暴风骤雨动画，动画结束后角色所在地块变为空地块
int needLostStrength = 80-player1->skill_vector.at(0)*10;
if(player1->getStrength() >= needLostStrength)
{
showSkillSprites();
player1->setStrength(player1->getStrength()-needLostStrength);
refreshStrengthLabel(player1,0);
Point pointOfGL = Util::map2GL(ccp(player1->stop_x,player1->stop_y),_map);

}),NULL));
}else //如果体力不足，Toast显示提示信息
{

LanguageString::getInstance()->getLanguageString(YOUR_STRENGTH_IS_LOW)->getCString(),
TOAST_SHOW_TIME,
winSize/2);
}
}
if(tag == skillStepTag)
{//如果点击了随心步 则显示随心步步数按钮界面
showStepButton(!isStepLayerShow);
isStepLayerShow = !isStepLayerShow;
}
if(tag == skillTransferTag)
{//如果点击巧取豪夺
if(player1->stop_x< 0)
{
return;
}
//判断角色体力值和技能所需的体力值是否满足技能需求
int needLostStrength = 110-player1->skill_vector.at(0)*10;
if(player1->getStrength() >= needLostStrength)
{
//记录夺取地块的等级
int transferLand = 0;
if(transferLandTag== MSG_PAY_TOLLS_1_TAG)

}),NULL));
}
}else
{
CocosToast::createToast(this,
LanguageString::getInstance()->getLanguageString(YOUR_STRENGTH_IS_LOW)->getCString(),
TOAST_SHOW_TIME,
winSize/2);
}
}
}
//修改goButtonCallback方法，添加技能按钮和随心步步数按钮相应
void GameBaseScene::goButtonCallback(cocos2d::CCObject *pSender)
{
int tag = ((Node*)pSender)->getTag();
....................
//当点击技能按钮时，显示或隐藏技能界面
if(tag == skillButtonTag)
{
skillStorm->setSkillGrade(player1->skill_vector.at(0));

}
//当点击步数按钮时
if(tag == step1_tag || tag == step2_tag || tag == step3_tag || tag == step4_tag || tag == step5_tag || tag == step6_tag)
{
int needLostStrength = 60-player1->skill_vector.at(1)*10;
//当体力值足够时，角色减少相应体力值，同时隐藏技能界面，人物进行相应步数的行走
if(player1->getStrength() >= needLostStrength)
{
player1->setStrength(player1->getStrength()-needLostStrength);
refreshStrengthLabel(player1,0);
showSkillSprites();
int steps = tag - stepBaseTag;
RouteNavigation::getInstance()->getPath(player1,steps,canPassGrid,tiledRowsCount,tiledColsCount);
std::vector<int> colVector = RouteNavigation::getInstance()->getPathCols_vector();
std::vector<int> rowVector = RouteNavigation::getInstance()->getPathRow_vector();

}
}
}
//该方法进行技能界面显示，当显示时，向上移动，隐藏时，向下移动
void GameBaseScene::showSkillSprites()
{

{
showStepButton(!isStepLayerShow);
isStepLayerShow = !isStepLayerShow;
}
}
}
5、添加对手机器人技能
void RicherGameController::pickOnePlayerToGo()
{
...............
if(richerPlayer->getTag() == PLAYER_1_TAG )
{
NotificationCenter::getInstance()->postNotification(MSG_GO,String::createWithFormat("%d",MSG_GO_SHOW_TAG));
return;
}
//当不是第一角色时
if(richerPlayer->stop_x > 0)
{
//获取角色所在地块id值
int gid = GameBaseScene::landLayer->getTileGIDAt(ccp(richerPlayer->stop_x,richerPlayer->stop_y));
//如果地块不是自己的，则随机使用技能
if(gid != GameBaseScene::blank_land_tiledID && gid != GameBaseScene::player2_building_1_tiledID && gid != GameBaseScene::player2_building_2_tiledID && gid != GameBaseScene::player2_building_3_tiledID)
{ //获取角色体力
int playerStrength = richerPlayer->getStrength();
//随机取得要使用的技能
int randomSkill_index = rand()%3;
int needLostStrength = 0;
int landLevel = 0;
//记录地块的等级
if(gid == GameBaseScene::player1_building_1_tiledID)
{
landLevel =GameBaseScene::player2_building_1_tiledID;
}
if(gid == GameBaseScene::player1_building_2_tiledID)
{
landLevel =GameBaseScene::player2_building_2_tiledID;
}
if(gid == GameBaseScene::player1_building_3_tiledID)
{
landLevel =GameBaseScene::player2_building_3_tiledID;
}
//获取使用技能需要耗费的体力
switch(randomSkill_index)
{
case 0:
{
needLostStrength = 80-richerPlayer->skill_vector.at(0)*10;
break;
}
case 1:
{
}
case 2:
{
needLostStrength = 110-richerPlayer->skill_vector.at(2)*10;
break;
}
}
//如果角色体力值满足要求，发送使用技能的消息，然后方法返回
if(playerStrength >= needLostStrength)
{
String * str = String::createWithFormat("%d-%f-%f-%d-%d-%d-%d",MSG_USE_SKILL_TAG,richerPlayer->stop_x ,richerPlayer->stop_y,richerPlayer->getTag(),randomSkill_index,needLostStrength,landLevel);
NotificationCenter::getInstance()->postNotification(MSG_USE_SKILL,str);
return;
}
}
}
如果地块是自己的时候，角色则行走
int randNumber = rand()%6 + 1;
RouteNavigation::getInstance()->getPath(richerPlayer,randNumber,GameBaseScene::canPassGrid,GameBaseScene::tiledRowsCount,GameBaseScene::tiledColsCount);
richerPlayer->startGo(RouteNavigation::getInstance()->getPathRow_vector(),RouteNavigation::getInstance()->getPathCols_vector());
return;
}
}
//当角色收到消息时
void GameBaseScene::receivedNotificationOMsg(Object* data)
{
...............
case MSG_USE_SKILL_TAG:
{
//获取角色的tag
int playerTag = messageVector.at(3)->intValue();
//角色要使用的技能
int kill_index =messageVector.at(4)->intValue();
//使用技能需要耗费的体力
int needLostStrength = messageVector.at(5)->intValue();
//当前地块的等级
int landLevel = messageVector.at(6)->intValue();
if(playerTag == PLAYER_2_TAG)
{
//让角色减少相应的体力
player2->setStrength(player2->getStrength()-needLostStrength);
refreshStrengthLabel(player2,0);
Point pointOfGL = Util::map2GL(ccp(player2->stop_x,player2->stop_y),_map);
//播放技能相应动画
switch(kill_index)
{
case 0://暴风骤雨
{
rainSprite = Sprite::createWithSpriteFrame(player2->getRainSkill()->getAnimation()->getFrames().at(0)->getSpriteFrame());
addChild(rainSprite);
rainSprite->setAnchorPoint(ccp(0,0));
rainSprite->setPosition(pointOfGL+ccp(-tiledWidth/2,tiledHeight/2));
//动画播放完毕后，设置地块为空地块。并发送角色继续行走的消息
rainSprite->runAction(Sequence::create(player2->getRainSkill(),CallFunc::create([this]()
{
landLayer->setTileGID(blank_land_tiledID,ccp(player2->stop_x,player2->stop_y));
rainSprite->removeFromParent();
NotificationCenter::getInstance()->postNotification(MSG_PICKONE_TOGO,String::createWithFormat("%d",MSG_PICKONE_TOGO_TAG));
}),NULL));
break;
}
case 1://随心步，这个方法暂时不写，后期大家可以自己添加
{
}
case 2://巧取豪夺
{
transferSprite = Sprite::createWithSpriteFrame(player2->getTransfer_skill()->getAnimation()->getFrames().at(0)->getSpriteFrame());
addChild(transferSprite);
transferSprite->setAnchorPoint(ccp(0,0));
transferSprite->setPosition(pointOfGL);
//动画播放完毕后，设置地块为自己相应等级地块。并发送角色继续行走的消息
transferSprite->runAction(Sequence::create(player2->getTransfer_skill(),CallFunc::create([this,landLevel]()
{
landLayer->setTileGID(landLevel,ccp(player2->stop_x,player2->stop_y));
transferSprite->removeFromParent();
NotificationCenter::getInstance()->postNotification(MSG_PICKONE_TOGO,String::createWithFormat("%d",MSG_PICKONE_TOGO_TAG));
}),NULL));
break;
}
}
}
break;
}
...............
}
至此人物技能基本流程结束
代码中其他修改部分：
骰子动画效果感觉有些多余，代码中注释掉了
