有没有人对如何在Sprite Kit for iOS中实现慢动作效果有任何好的想法？这将使包括粒子节点在内的所有节点以1/2的速度移动,并使粒子移动速度的1/2.
我可以想一想如何手动执行此操作,但我想在开始实现之前获得更多想法.
解决方法
我相信你能做到：
self.physicsWorld.speed = 0.5;
文档参考：
speed
The rate at which the simulation executes.
@property(nonatomic) CGFloat speed
discussion
The default value is 1.0,which means the simulation runs at normal speed. A value other than the default changes the rate at which time passes in the physics simulation. For example,a speed value of 2.0 indicates that time in the physics simulation passes twice as fast as the scene’s simulation time. A value of 0.0 pauses the physics simulation.Availability Available in iOS 7.0 and later. Declared In SKPhysicsWorld.h
