此长方体厚度很薄 然后设置模型的contents为红包的图片 2.用仿真框架让红包掉下来 3.多设置几个源头 但正上方不要设置 否则屏幕经常会给一个红包遮住 #####关键性代码： geometerNode.physicsBody...Y = (NSInteger) (1 ); NSInteger Z = (NSInteger)(arc4random_uniform(9)) - 4; [geometerNode.physicsBody...在SceneKit中所有的物理对象都是SCNPhysicsBody, 然后需要把该对象绑定到SCNNode的physicsBody实例属性, 然后物理引擎就可以进行仿真模拟了。
接下来,我们给地板 球体 和 正方体 同时设置物理身体 floorNode.physicsBody = SCNPhysicsBody.static() sphereNode.physicsBody...= SCNPhysicsBody.kinematic() boxNode.physicsBody = SCNPhysicsBody.dynamic() 测试也无效,原因不详
使之成为一个可使用引用计数的对象 比如： PhysicsBody* PhysicsBody::create() { PhysicsBody* body = new (std::nothrow)...PhysicsBody(); if (body && body->init()) { body->autorelease();//此处使用autorelease把body增加到自己主动释放池
PhysicsMaterial(0.1f, 1.0f, 0.0f)); // 2 physicsBody->setDynamic(true); // 3 physicsBody->setCategoryBitmask...((int)PhysicsCategory::Monster); physicsBody->setCollisionBitmask((int)PhysicsCategory::None); physicsBody...这是上面的代码的作用： 1.为精灵创建一个PhysicsBody。...= PhysicsBody::createCircle(projectileSize.width/2 ); physicsBody->setDynamic(true); physicsBody->setCategoryBitmask...((int)PhysicsCategory::Projectile); physicsBody->setCollisionBitmask((int)PhysicsCategory::None); physicsBody
