cocos2dx游戏--欢欢英雄传说--添加动作
添加完人物之后接着给人物添加上动作。
我们为hero添加4个动作：attack（由3张图片构成）,walk（由2张图片构成）,hit（由1张图片构成）,dead（由1张图片构成）；同样，为enemy添加4个动作：attack（由3张图片构成）,walk（由2张图片构成）,hit（由1张图片构成）,dead（由1张图片构成）。
取名分别为：hero-attack-0.png,hero-attack-1.png,hero-attack-2.png,hero-walk-0.png,hero-walk-1.png,hero-hit-0.png,hero-dead-0.png,enemy-attack-0.png,enemy-attack-1.png,enemy-attack-2.png,enemy-walk-0.png,enemy-walk-1.png,enemy-hit-0.png,enemy-dead-0.png。
其中，hero开头的表示hero的动作；enemy开头的表示enemy的动作。attack表示攻击时的动作，walk表示走路时的动作，hit表示受伤时的动作，dead表示死亡时的动作。这些图片资源如下：
hero-attack-0.png:
hero-attack-1.png:
hero-attack-2.png:
hero-walk-0.png:
hero-walk-1.png:
hero-hit-0.png:
hero-dead-0.png:
enemy-attack-0.png:
enemy-attack-1.png:
enemy-attack-2.png:
enemy-walk-0.png:
enemy-walk-1.png:
enemy-hit-0.png:
enemy-dead-0.png:
然后这些图片都存放在Resources/image/目录下，我们需要为这些图片组合成一些列的动作。下面的代码演示了如何将这些图片组合成8个animation并存放在AnimationCache中：
HelloWorld::init()部分代码:
// hero-attack
spriteFrame = CCSpriteFrame::create("images/hero-attack-0.png", CCRectMake(, , , ));
SpriteFrameCache::getInstance()->addSpriteFrame(spriteFrame, "hero-attack-0.png");
spriteFrame = CCSpriteFrame::create("images/hero-attack-1.png", CCRectMake(, , , ));
SpriteFrameCache::getInstance()->addSpriteFrame(spriteFrame, "hero-attack-1.png");
spriteFrame = CCSpriteFrame::create("images/hero-attack-2.png", CCRectMake(, , , ));
SpriteFrameCache::getInstance()->addSpriteFrame(spriteFrame, "hero-attack-2.png");
// hero-walk
spriteFrame = CCSpriteFrame::create("images/hero-walk-0.png", CCRectMake(, , , ));
SpriteFrameCache::getInstance()->addSpriteFrame(spriteFrame, "hero-walk-0.png");
spriteFrame = CCSpriteFrame::create("images/hero-walk-1.png", CCRectMake(, , , ));
SpriteFrameCache::getInstance()->addSpriteFrame(spriteFrame, "hero-walk-1.png");
// hero-hit
spriteFrame = CCSpriteFrame::create("images/hero-hit-0.png", CCRectMake(, , , ));
SpriteFrameCache::getInstance()->addSpriteFrame(spriteFrame, "hero-hit-0.png");
// hero-dead
spriteFrame = CCSpriteFrame::create("images/hero-dead-0.png", CCRectMake(, , , ));
SpriteFrameCache::getInstance()->addSpriteFrame(spriteFrame, "hero-dead-0.png"); // enemy-attack
spriteFrame = CCSpriteFrame::create("images/enemy-attack-0.png", CCRectMake(, , , ));
SpriteFrameCache::getInstance()->addSpriteFrame(spriteFrame, "enemy-attack-0.png");
spriteFrame = CCSpriteFrame::create("images/enemy-attack-1.png", CCRectMake(, , , ));
SpriteFrameCache::getInstance()->addSpriteFrame(spriteFrame, "enemy-attack-1.png");
spriteFrame = CCSpriteFrame::create("images/enemy-attack-2.png", CCRectMake(, , , ));
SpriteFrameCache::getInstance()->addSpriteFrame(spriteFrame, "enemy-attack-2.png");
// enemy-walk
spriteFrame = CCSpriteFrame::create("images/enemy-walk-0.png", CCRectMake(, , , ));
SpriteFrameCache::getInstance()->addSpriteFrame(spriteFrame, "enemy-walk-0.png");
spriteFrame = CCSpriteFrame::create("images/enemy-walk-1.png", CCRectMake(, , , ));
SpriteFrameCache::getInstance()->addSpriteFrame(spriteFrame, "enemy-walk-1.png");
// enemy-hit
spriteFrame = CCSpriteFrame::create("images/enemy-hit-0.png", CCRectMake(, , , ));
SpriteFrameCache::getInstance()->addSpriteFrame(spriteFrame, "enemy-hit-0.png");
// enemy-dead
spriteFrame = CCSpriteFrame::create("images/enemy-dead-0.png", CCRectMake(, , , ));
SpriteFrameCache::getInstance()->addSpriteFrame(spriteFrame, "enemy-dead-0.png"); /** add animation cache **/
// hero-attack
auto animation = Animation::create();
animation->setDelayPerUnit(0.2f);
for (int i = ; i < ; i ++)
{
auto sfName =String::createWithFormat("hero-attack-%d.png", i)->getCString();
animation->addSpriteFrame(SpriteFrameCache::getInstance()->getSpriteFrameByName(sfName));
}
AnimationCache::getInstance()->addAnimation(animation, "hero-attack");
// hero-walk
animation = Animation::create();
animation->setDelayPerUnit(0.2f);
for (int i = ; i < ; i ++)
{
auto sfName =String::createWithFormat("hero-walk-%d.png", i)->getCString();
animation->addSpriteFrame(SpriteFrameCache::getInstance()->getSpriteFrameByName(sfName));
}
AnimationCache::getInstance()->addAnimation(animation, "hero-walk");
// hero-hit
animation = Animation::create();
animation->setDelayPerUnit(0.2f);
for (int i = ; i < ; i ++)
{
auto sfName =String::createWithFormat("hero-hit-%d.png", i)->getCString();
animation->addSpriteFrame(SpriteFrameCache::getInstance()->getSpriteFrameByName(sfName));
}
AnimationCache::getInstance()->addAnimation(animation, "hero-hit");
// hero-dead
animation = Animation::create();
animation->setDelayPerUnit(0.2f);
for (int i = ; i < ; i ++)
{
auto sfName =String::createWithFormat("hero-dead-%d.png", i)->getCString();
animation->addSpriteFrame(SpriteFrameCache::getInstance()->getSpriteFrameByName(sfName));
}
AnimationCache::getInstance()->addAnimation(animation, "hero-dead"); // enemy-attack
animation = Animation::create();
animation->setDelayPerUnit(0.2f);
for (int i = ; i < ; i ++)
{
auto sfName =String::createWithFormat("enemy-attack-%d.png", i)->getCString();
animation->addSpriteFrame(SpriteFrameCache::getInstance()->getSpriteFrameByName(sfName));
}
AnimationCache::getInstance()->addAnimation(animation, "enemy-attack");
// hero-walk
animation = Animation::create();
animation->setDelayPerUnit(0.2f);
for (int i = ; i < ; i ++)
{
auto sfName =String::createWithFormat("enemy-walk-%d.png", i)->getCString();
animation->addSpriteFrame(SpriteFrameCache::getInstance()->getSpriteFrameByName(sfName));
}
AnimationCache::getInstance()->addAnimation(animation, "enemy-walk");
// hero-hit
animation = Animation::create();
animation->setDelayPerUnit(0.2f);
for (int i = ; i < ; i ++)
{
auto sfName =String::createWithFormat("enemy-hit-%d.png", i)->getCString();
animation->addSpriteFrame(SpriteFrameCache::getInstance()->getSpriteFrameByName(sfName));
}
AnimationCache::getInstance()->addAnimation(animation, "enemy-hit");
// hero-dead
animation = Animation::create();
animation->setDelayPerUnit(0.2f);
for (int i = ; i < ; i ++)
{
auto sfName =String::createWithFormat("enemy-dead-%d.png", i)->getCString();
animation->addSpriteFrame(SpriteFrameCache::getInstance()->getSpriteFrameByName(sfName));
}
AnimationCache::getInstance()->addAnimation(animation, "enemy-dead");
我们在Player中添加一个函数来查看效果：
在Player.h中添加：
void runActionForever(std::string action);
在Player.cpp中添加：
void Player::runActionForever(std::string action)
{
auto animation = AnimationCache::getInstance()->getAnimation(action);
auto animate = Animate::create(animation);
this->runAction(RepeatForever::create(animate));
}
然后在HelloWorld::init()最后添加如下代码查看效果：
player->runActionForever("hero-attack");
enemy->runActionForever("enemy-walk");
效果如下：
#include "HelloWorldScene.h"
#include "SimpleAudioEngine.h"
#include "Player.h" USING_NS_CC; Scene* HelloWorld::createScene()
{
// 'scene' is an autorelease object
auto scene = Scene::create(); // 'layer' is an autorelease object
auto layer = HelloWorld::create(); // add layer as a child to scene
scene->addChild(layer); // return the scene
return scene;
} // on "init" you need to initialize your instance
bool HelloWorld::init()
{
if ( !Layer::init() )
{
return false;
} auto visibleSize = Director::getInstance()->getVisibleSize();
Vec2 origin = Director::getInstance()->getVisibleOrigin(); Sprite* background = Sprite::create("images/background.png");
background->setPosition(origin + visibleSize/);
this->addChild(background); SpriteFrame *spriteFrame = CCSpriteFrame::create("images/hero-0.png", CCRectMake(, , , ));
SpriteFrameCache::getInstance()->addSpriteFrame(spriteFrame, "hero-0.png");
spriteFrame = CCSpriteFrame::create("images/enemy-0.png", CCRectMake(, , , ));
SpriteFrameCache::getInstance()->addSpriteFrame(spriteFrame, "enemy-0.png");
// hero-attack
spriteFrame = CCSpriteFrame::create("images/hero-attack-0.png", CCRectMake(, , , ));
SpriteFrameCache::getInstance()->addSpriteFrame(spriteFrame, "hero-attack-0.png");
spriteFrame = CCSpriteFrame::create("images/hero-attack-1.png", CCRectMake(, , , ));
SpriteFrameCache::getInstance()->addSpriteFrame(spriteFrame, "hero-attack-1.png");
spriteFrame = CCSpriteFrame::create("images/hero-attack-2.png", CCRectMake(, , , ));
SpriteFrameCache::getInstance()->addSpriteFrame(spriteFrame, "hero-attack-2.png");
// hero-walk
spriteFrame = CCSpriteFrame::create("images/hero-walk-0.png", CCRectMake(, , , ));
SpriteFrameCache::getInstance()->addSpriteFrame(spriteFrame, "hero-walk-0.png");

SpriteFrameCache::getInstance()->addSpriteFrame(spriteFrame, "hero-walk-1.png");
// hero-hit
spriteFrame = CCSpriteFrame::create("images/hero-hit-0.png", CCRectMake(, , , ));
SpriteFrameCache::getInstance()->addSpriteFrame(spriteFrame, "hero-hit-0.png");

SpriteFrameCache::getInstance()->addSpriteFrame(spriteFrame, "enemy-attack-0.png");
spriteFrame = CCSpriteFrame::create("images/enemy-attack-1.png", CCRectMake(, , , ));
SpriteFrameCache::getInstance()->addSpriteFrame(spriteFrame, "enemy-attack-1.png");
