在cocos2dx 中的tests 项目里 已经带了 足够多的 动画事例
ActionsTest
我只是看了其中一些 自我感觉比较常用的动画
ActionMove 移动
在cocos2d-x中移动分 to 和 by 两种
1 CCSize s = CCDirector::sharedDirector()->getWinSize();
2
3 CCActionInterval* actionTo = CCMoveTo::create(2, CCPointMake(s.width-40, s.height-40)); //2s的时间移动到某个位置相对于屏幕
4 CCActionInterval* actionBy = CCMoveBy::create(2, CCPointMake(80,80)); //2s的时间移动到80,80
5 CCActionInterval* actionByBack = actionBy->reverse(); //让动作回复到actionBy之前的地方
6
7 m_tamara->runAction( actionTo); //执行actionTo
8 m_grossini->runAction( CCSequence::create(actionBy, actionByBack, NULL)); //顺序执行(actionBy,actionByBack),必须用NULL结尾
9 m_kathia->runAction(CCMoveTo::create(1, CCPointMake(40,40))); //1s的时间移动到40,40
ActionScale 缩放
同样分为 to 和 by 记得有地方说这两种缩放 效果会不一样 但是我在win32 上实验 缩放大小是一样的,以后在到xcode 上实验
1 CCActionInterval* actionTo = CCScaleTo::create(2.0f, 0.5f); //2个参数(时间,放大倍数)
2 CCActionInterval* actionBy = CCScaleBy::create(2.0f, 1.0f, 10.0f); //三个参数(时间,x方向放大倍数,y方向放大倍数)
3 CCActionInterval* actionBy2 = CCScaleBy::create(2.0f, 5.0f, 1.0f);
4
5 m_grossini->runAction( actionTo);
6 m_tamara->runAction( CCSequence::create(actionBy, actionBy->reverse(), NULL));
7 m_kathia->runAction( CCSequence::create(actionBy2, actionBy2->reverse(), NULL));
ActionSkew
还没研究 暂时留在这里
1 CCActionInterval *actionTo = CCSkewTo::create(2, 37.2f, -37.2f);
2 CCActionInterval *actionToBack = CCSkewTo::create(2, 0, 0);
3 CCActionInterval *actionBy = CCSkewBy::create(2, 0.0f, -90.0f);
4 CCActionInterval *actionBy2 = CCSkewBy::create(2, 45.0f, 45.0f);
5 CCActionInterval *actionByBack = actionBy->reverse();
6
7 m_tamara->runAction(CCSequence::create(actionTo, actionToBack, NULL));
8 m_grossini->runAction(CCSequence::create(actionBy, actionByBack, NULL));
9
10 m_kathia->runAction(CCSequence::create(actionBy2, actionBy2->reverse(), NULL));
ActionRotate
旋转
1 CCActionInterval* actionTo = CCRotateTo::create( 2, 45); //2s内顺时针旋转45度(每跨度180,旋转方向会相反)
2 CCActionInterval* actionTo2 = CCRotateTo::create( 2, -45); //2s内逆时针旋转45度(每跨度180,旋转方向会相反)
3 CCActionInterval* actionTo0 = CCRotateTo::create(2 , 0);
4 m_tamara->runAction( CCSequence::create(actionTo, actionTo0, NULL));
5
6 CCActionInterval* actionBy = CCRotateBy::create(2 , 360); //2s内自身旋转360度,正数为顺时针旋转,负数相反
7 CCActionInterval* actionByBack = actionBy->reverse(); //回复
8 m_grossini->runAction( CCSequence::create(actionBy, actionByBack, NULL));
9
10 m_kathia->runAction( CCSequence::create(actionTo2, actionTo0->copy()->autorelease(), NULL));
11 //actionTo0->copy()->autorelease() 不清楚 作用
ActionJump
跳动移动
1 CCActionInterval* actionTo = CCJumpTo::create(2, CCPointMake(300,300), 50, 4); //2s内跳向300,300的位置,跳跃高度为50,跳跃次数为4
2 CCActionInterval* actionBy = CCJumpBy::create(2, CCPointMake(300,0), 50, 4); //向x方向跳动300像素,跳跃高度为50,跳跃次数为4
3 CCActionInterval* actionUp = CCJumpBy::create(2, CCPointMake(0,0), 80, 4); //原地跳动 高度80 次数为4
4 CCActionInterval* actionByBack = actionBy->reverse(); //回复
5
6 m_tamara->runAction( actionTo);
7 m_grossini->runAction( CCSequence::create(actionBy, actionByBack, NULL)); //顺序执行actionBy, actionByBack动作
8 m_kathia->runAction( CCRepeatForever::create(actionUp)); //CCRepeatForever 一直重复相同的动作
顺序执行和并发执行
1 CCMoveTo *moveTo = CCMoveTo::actionWithDuration(5, ccp(150,250));
2 CCScaleTo *scaleTo = CCScaleTo::actionWithDuration(5, 3);
3 CCDelayTime *waiting = CCDelayTime::actionWithDuration(2);//停滞2秒
4 CCRotateBy *rotBy = CCRotateBy::actionWithDuration(5, 180);
5 //顺序执行定义好的动画
6 _sprite1->runAction(CCSequence::actions(moveTo,waiting,scaleTo,waiting,rotBy,NULL));
7 //并发执行（同时执行）各类动画
8 _sprite2->runAction(CCSpawn::actions(moveTo,scaleTo,rotBy));
9 //一直重复相同的动作
10 _sprite3->runAction(CCRepeatForever::actionWithAction(rotBy));
_sprite->stopAction(scale);//停住某个action,只能停止单个动画，在组合动画中不能停住
带有回调方法的移动
ActionCallFunc 无参回调
1 void ActionCallFunc::onEnter()
2 {
3 ActionsDemo::onEnter();
4
5 centerSprites(3);
6
7 CCFiniteTimeAction* action = CCSequence::create(
8 CCMoveBy::create(2, CCPointMake(200,0)),
9 CCCallFunc::create(this, callfunc_selector(ActionCallFunc::callback1)),
10 NULL);
11
12 CCFiniteTimeAction* action2 = CCSequence::create(
13 CCScaleBy::create(2 , 2),
14 CCFadeOut::create(2),
15 CCCallFuncN::create(this, callfuncN_selector(ActionSequence2::callback2)),
16 NULL);
17
18 CCFiniteTimeAction* action3 = CCSequence::create(
19 CCRotateBy::create(3 , 360),
20 CCFadeOut::create(2),
21 CCCallFuncND::create(this, callfuncND_selector(ActionSequence2::callback3), (void*)0xbebabeba),
22 NULL);
23
24 m_grossini->runAction(action);
25 m_tamara->runAction(action2);
26 m_kathia->runAction(action3);
27 }

29
30 void ActionCallFunc::callback1()
31 {
32 CCSize s = CCDirector::sharedDirector()->getWinSize();
33 CCLabelTTF *label = CCLabelTTF::create("callback 1 called", "Marker Felt", 16);
34 label->setPosition(CCPointMake( s.width/4*1,s.height/2));
35
36 addChild(label);
37 }
38
39 void ActionCallFunc::callback2(CCNode* pSender)
40 {
41 CCSize s = CCDirector::sharedDirector()->getWinSize();
42 CCLabelTTF *label = CCLabelTTF::create("callback 2 called", "Marker Felt", 16);
43 label->setPosition(CCPointMake( s.width/4*2,s.height/2));
44
45 addChild(label);
46 }
47
48 void ActionCallFunc::callback3(CCNode* pTarget, void* data)
49 {
50 CCSize s = CCDirector::sharedDirector()->getWinSize();
51 CCLabelTTF *label = CCLabelTTF::create("callback 3 called", "Marker Felt", 16);
52 label->setPosition(CCPointMake( s.width/4*3,s.height/2));
53 addChild(label);
54 }
55
有参数的回调
1 void ActionCallFuncND::onEnter()
2 {
3 ActionsDemo::onEnter();
4
5 centerSprites(1);
6
7 CCFiniteTimeAction* action = CCSequence::create(CCMoveBy::create(2.0f, ccp(200,0)),
8 CCCallFuncND::create(this, callfuncND_selector(ActionCallFuncND::removeFromParentAndCleanup), (void*)true),
9 NULL);
10
11 m_grossini->runAction(action);
12 }
13
14 std::string ActionCallFuncND::title()
15 {
16 return "CallFuncND + auto remove";
17 }
18
19 std::string ActionCallFuncND::subtitle()
20 {
21 return "CallFuncND + removeFromParentAndCleanup. Grossini dissapears in 2s";
22 }
23
24 void ActionCallFuncND::removeFromParentAndCleanup(CCNode* pSender, void* data)
25 {
26 bool bCleanUp = (bool)data;
27 m_grossini->removeFromParentAndCleanup(bCleanUp);
28 }
其他动画可以在tests里自行查找
cocos2d-x提供丰富的动画
