Cocos2d-x 3.3 的3D开发功能介绍
|
昨天去成都参加GMGDC 全球移动游戏开发者大会，据蓝港互动CEO王峰谈到《手机游戏开发如何走好第一步》时谈到 目前手游公司有10000家，没错，红海，都快变黑海了 这么多公司和产品如何竞争，大量的同质化产品，（王峰给我的建议是与其在红海中厮杀不如想象未来的蓝海在哪，听明白的请举起右手） 先不管这些了，作为程序员来讲我们看到了20万的人才缺口（如果每家公司招20个人，听明白的请举起左手） 今天下载了Cocos2d-x 3.3，3D功能果然强大 主要有以下功能： 1. 基本的Sprite3D使用，加载静态模型和动态模型，看 Sprite3DBasicTest 2.Sprite3D对象的旋转，缩放等Action操作 3.Sprite3D中使用Shader特效，实现outLine 4.Animate3D来创建3D动画
5.动态增加3D骨骼，实现怪物添加手持武器功能 6，动态修改骨骼皮肤实现换装功能Sprite3DReskinTest 7.通过包围盒实现3D模型碰撞，Sprite3DWithOBBPerfromanceTest 8.实现水平镜像3D模型，Sprite3DMirrorTest 下面介绍一下Sprite3DTest里面的源码 #include"Sprite3DTest.h" #include"3d/CCAnimation3D.h" #include"3d/CCAnimate3D.h" #include"3d/CCAttachNode.h" #include"3d/CCRay.h" #include"3d/CCSprite3D.h" #include"renderer/CCVertexIndexBuffer.h" #include"DrawNode3D.h" 1.在Scene中添加3D模型 voidSprite3DBasicTest::addNewSpriteWithCoords(Vec2p) { //这里的obj可以使用3dmax直接导出 // //option 1: load a obj that contain the texture in it 第一种方法是在模型文件中包含了纹理 // auto sprite = Sprite3D::create("sprite3dTest/scene01.obj"); //option 2: load obj and assign the texture 第二种方法是在模型文件中不包含纹理 autosprite =Sprite3D::create("Sprite3DTest/boss1.obj"); sprite->setScale(3.f); sprite->setTexture("Sprite3DTest/boss.png"); //在Sprite3D中包含了一些基本的Shader特效，下面是让3D模型实现outline //sprite->setEffect(cocos2d::EFFECT_OUTLINE); //add to scene addChild( sprite ); sprite->setPosition(Vec2( p.x,p.y) ); ActionInterval* action; floatrandom =CCRANDOM_0_1();

addChild( sprite1 ); sprite1->runAction(RepeatForever::create(RotateBy::create(3,360)));
autosprite2 =Sprite3D::create("Sprite3DTest/boss1.obj"); sprite2->setScale(4.f); sprite2->setTexture("Sprite3DTest/boss.png"); sprite2->setPosition(Vec2(s.width/2,s.height/2) ); sprite2->setAnchorPoint(Vec2(0.5,0.5)); addChild( sprite2 ); sprite2->runAction(RepeatForever::create(RotateBy::create(3,-360)));
// Make sprite1 touchable autolistener1 =EventListenerTouchOneByOne::create(); listener1->setSwallowTouches(true); listener1->onTouchBegan= [](Touch* touch,Event* event){ autotarget =static_cast<Sprite3D*>(event->getCurrentTarget());
Rectrect = target->getBoundingBox(); if(rect.containsPoint(touch->getLocation())) { log("sprite3d began... x = %f,y = %f",touch->getLocation().x,touch->getLocation().y); target->setOpacity(100); returntrue; } returnfalse; };
listener1->onTouchMoved= [](Touch* touch,51); font-family:Arial; font-size:14px; line-height:26px"> autotarget =static_cast<Sprite3D*>(event->getCurrentTarget()); target->setPosition(target->getPosition() + touch->getDelta()); listener1->onTouchEnded= [=](Touch* touch,Event* event){ autotarget =static_cast<Sprite3D*>(event->getCurrentTarget()); log("sprite3d onTouchesEnded.. "); target->setOpacity(255); };
_eventDispatcher->addEventListenerWithSceneGraphPriority(listener1,sprite1); _eventDispatcher->addEventListenerWithSceneGraphPriority(listener1->clone(),sprite2); 3.在一个Sprite3D上使用Shader Effect3D继承REF封装了Shader的处理 Effect3DOutline继承了Effect3D，封装了Outline类型的Shader EffectSprite3D继承了Sprite3D封装了对Effect3DOutline的调用
