像Instagram iOS应用的登录屏幕一样，如何为Sprite-Kit游戏的背景设置动画? [英] How to animate background of a Sprite-Kit game just like the login screen of Instagram iOS app?

问题描述

我正在Sprite-Kit中创建一个游戏，并且希望以与Instagram在其登录屏幕上类似的方式为背景制作动画.

I am creating a game in Sprite-Kit and would want to animate the background in the similar fashion as Instagram does on its login screen.

基本上，我只是想知道如何在游戏中具有背景，就像Instagram应用在其登录屏幕上一样，即粉红色的屏幕逐渐变为紫罗兰色，然后变为红色，具有非常细腻的流动效果从右到左.我知道如何为渐变设置动画，但是我正在谈论的那种微妙的效果似乎并没有产生气流或气流的流动(我爱上了这种效果).

Basically, I just want to know how to have a background in my game just like the Instagram app has on its login screen, i.e the pink colored screen which gradually changes to violet color and then to red with a very subtle flowing effect from right to left. I know how to animate the gradient but that subtle effect that I'm talking about which gives quite a view of a gas or stream flowing (I'm in love with that effect) doesn't seem to be happening.
