objective c - Couldn't make a particle follow a path in spriteKit -

this animation in xcode skemitter editor (i want achieve on iphone) :

this animation on iphone (i don't want animation):

using code:

    let sparkemmiter = skemitternode(filenamed: "fireflies.sks")     self.addchild(sparkemmiter) // self skscene      var circle: cgpathref? = nil     circle = cgpathcreatewithellipseinrect(cgrectmake(400, 200, 200, 200), nil)     let followtrack = skaction.followpath(circle!, asoffset: false, orienttopath: true, duration: 3.0)     let followtrackforever = skaction.repeatactionforever(followtrack)     //sparkemmiter.runaction(followtrackforever)     sparkemmiter.particleaction = followtrackforever; 

this emitter settings:

i tried both runaction , particleaction referring question, doesn't work wanted to...

-----------------update----------------------------------------------

tried solution mentioned hamobi (still doesn't work) :

    //if you:     // 1) i'd make sprite ,      let texture = sktexture(imagenamed: "spark")     let mysprite = skspritenode(texture: texture)     self.addchild(mysprite)      // 2) add emitter in first example child.     let sparkemmiter = skemitternode(filenamed: "fireflies.sks")     mysprite.addchild(sparkemmiter)      // 3) i'd set emitters targetnode scene.     sparkemmiter.targetnode = self      // 4) i'd animate sprite in arc.     var circle: cgpathref? = nil     circle = cgpathcreatewithellipseinrect(cgrectmake(400, 200, 200, 200), nil)     let followtrack = skaction.followpath(circle!, asoffset: false, orienttopath: true, duration: 3.0)     let followtrackforever = skaction.repeatactionforever(followtrack)     //sparkemmiter.runaction(followtrackforever)     sparkemmiter.particleaction = followtrackforever; 

-----------------update 2----------------------------------------------

got it! thx hamobi :d result :d:d

if i'd make sprite , add emitter in first example child. i'd set emitters targetnode scene. i'd animate sprite in arc.

edit:

okay main thing missing should forget using particleaction. make mysprite run followtrackforever action.

heres code

//if you: // 1) i'd make sprite , let texture = sktexture(imagenamed: "spark") let mysprite = skspritenode(texture: texture) mysprite.position = cgpoint(x: self.size.width/2, y: self.size.height/2) self.addchild(mysprite)  // 2) add emitter in first example child. let sparkemmiter = skemitternode(filenamed: "fireflies.sks") mysprite.addchild(sparkemmiter)  // 3) i'd set emitters targetnode scene. sparkemmiter.targetnode = self  // 4) i'd animate sprite in arc. var circle: cgpathref? = nil circle = cgpathcreatewithellipseinrect(cgrectmake(100, 200, 200, 200), nil) let followtrack = skaction.followpath(circle!, asoffset: false, orienttopath: true, duration: 3.0) let followtrackforever = skaction.repeatactionforever(followtrack) mysprite.runaction(followtrackforever)
