ios - Sprite Kit iOS 中的慢动作

Question

有没有人知道如何在 Sprite Kit for iOS 中实现慢动作效果？这将使包括粒子节点在内的所有节点以 1/2 的速度移动，并使粒子以 1/2 的速度移动。

我可以想到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。

Answer 1

我相信你能做到:

self.physicsWorld.speed = 0.5;

文档引用:

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.
