I have a SKNode which I used as a container for other sprite nodes. I havw implemented pause functionality in my game. I have a 3 SKSpriteNodes. Two are applied with action and remaining is given a impulse. When user taps pause button I tried to pause container SKNode but it pauses only 2 SKSpriteNodes which have actions and it does not pause the remaining SKSpriteNode which was applies an impulse. Why pausing does not pause a node moving with a velocity ??
