ios - How to cancel one specific SKAction.movebyX in SpriteKit? -

-

i have skaction want cancel in touchesended. of right now, have code: self.player.removeallactions() , code works. problem i'm experiencing code cancelling actions including animation of player. did research , found code: player.removeactionforkey(), action code not include key. please see code below help. thank you.

import spritekit  var player = skspritenode()  //i skipped code in view did load.  // in touches began:  let rightmoveaction = skaction.movebyx(50, y: 0, duration: 0.1) player.runaction(skaction.repeatactionforever(rightmoveaction))  let leftmoveaction = skaction.movebyx(-50, y: 0, duration: 0.1) player.runaction(skaction.repeatactionforever(leftmoveaction))  // in touches ended  self.player.removeallactions()  // mentioned earlier, works need cancel 1 action not have animated player.

you can assign action key, , cancel referring key:

add key action:

player.runaction(skaction.repeatactionforever(rightmoveaction), withkey: "rightmove")

and remove doing this:

player.removeactionforkey("rightmove")
