updateAtTime time: TimeInterval){ print("检测碰撞") } 第二种 使用框架提供给我们的碰撞检测代理实现 首先你应该知道 SCNScene 有个属性叫做physicsWorld...(物理世界),physicsWorld对象有个碰撞代理SCNPhysicsContactDelegate scene.physicsWorld.contactDelegate = self /// 碰撞代理有三个方法...,叫做开始碰撞,碰撞中和结束碰撞 func physicsWorld(_ world: SCNPhysicsWorld, didBegin contact: SCNPhysicsContact){...print(contact) } func physicsWorld(_ world: SCNPhysicsWorld, didUpdate contact: SCNPhysicsContact){...print(contact) } func physicsWorld(_ world: SCNPhysicsWorld, didEnd contact: SCNPhysicsContact){
Ammo.btSequentialImpulseConstraintSolver(); var softBodySolver = new Ammo.btDefaultSoftBodySolver(); physicsWorld...Ammo.btSoftRigidDynamicsWorld( dispatcher, broadphase, solver, collisionConfiguration, softBodySolver); physicsWorld.setGravity...( new Ammo.btVector3( 0, gravityConstant, 0 ) ); physicsWorld.getWorldInfo().set_m_gravity( new...threeObject ); // Disable deactivation body.setActivationState( 4 ); } physicsWorld.addRigidBody...scene, camera ); } function updatePhysics( deltaTime ) { // Step world physicsWorld.stepSimulation
categoryBitMask、contactTestBitMask属性的id 用于标志2个物体是否会发生碰撞 #####代理设置 _jpARSCNView.scene.physicsWorld.contactDelegate...self.physicsBody.categoryBitMask = 2; self.physicsBody.contactTestBitMask = 1; // 这里是自己独立开一条线程出来 — (void)physicsWorld
physicsWorld.contactDelegate = self 代理SCNPhysicsContactDelegate 有三个方法 // 开始接触 optional public func physicsWorld...(_ world: SCNPhysicsWorld, didBegin contact: SCNPhysicsContact) // 接触中 optional public func physicsWorld...(_ world: SCNPhysicsWorld, didUpdate contact: SCNPhysicsContact) // 接触结束 optional public func physicsWorld
quat = new THREE.Quaternion(); // Physics variables var gravityConstant = - 9.8; var physicsWorld...Ammo.btSequentialImpulseConstraintSolver(); var softBodySolver = new Ammo.btDefaultSoftBodySolver(); physicsWorld...( new Ammo.btVector3( 0, gravityConstant, 0 ) ); physicsWorld.getWorldInfo().set_m_gravity( new...// Volume physic object var volumeSoftBody = softBodyHelpers.CreateFromTriMesh( physicsWorld.getWorldInfo...( scene, camera ); } function updatePhysics( deltaTime ) { // Step world physicsWorld.stepSimulation

/ Volume physic object var volumeSoftBody = softBodyHelpers.CreateFromTriMesh( physicsWorld.getWorldInfo...Ammo.castObject( volumeSoftBody, Ammo.btCollisionObject ).getCollisionShape().setMargin( margin ); physicsWorld.addSoftBody

写了一点点动画:微信小程序体验3D物理引擎-ammo.js,把碰撞检测的代码写一下,Mark下,记个笔记: 碰撞检测 function updatePhysics(deltaTime) { physicsWorld.stepSimulation...(deltaTime); //physicsWorld.performDiscreteCollisionDetection(); var numManifolds=dispatcher.getNumManifolds
让我们在physicsWorld上设置contactDelegate属性。在didMove函数中,将此代码设置在节点的初始化之上。...physicsWorld.contactDelegate = self 通过设置此代码,当两个物理实体发生碰撞时,将调用一些方法。
PhysicsWorld()默认是带重力的,大小为Vect(0.0f,-98.0f),也可以通过setGravity()方法来改变重力值,如下: self:getPhysicsWorld():setGravity...当调试结束需要发布游戏的时候,需要把该debug开关关闭 关闭DEBUG,传入参数cc.PhysicsWorld.DEBUGDRAW_NONE。 创建物理边界 在物理世界中,所以物体均受重力的影响。...Node的addChild方法,在Cocos2d-x 3. x中有对物理body做处理,它会自动把Node的body设置到scene的PhysicsWorld上去。...self:getPhysicsWorld():setGravity(cc.p(0,-100)) --重力 self:getPhysicsWorld():setDebugDrawMask(cc.PhysicsWorld.DEBUGDRAW_ALL...eventDispatcher:addEventListenerWithFixedPriority(contactListener,1) self:getPhysicsWorld():setDebugDrawMask(cc.PhysicsWorld.DEBUGDRAW_ALL
