Hello again.
I am working on a game project where I started using spawning function that calls
for a creature to be placed on the screen every X seconds.

With attempting to try Spine as my main animation controller I need to rework my
functions as well, so I tried something like that:

local enmDISgroup = display.newGroup();
   


---


   local enmTable = {};
   

   local json = spine.SkeletonJson.new()
   json.scale = 0.2
   

  

   


---

ENM1:
   local stateTable = {};
   

   local function spwnEnm(tpe, num)
                     local skeletonData = json:readSkeletonDataFile("examples/spineboy/" .. tpe .. ".json")

                 local enm = spine.Skeleton.new(skeletonData)

                 function enm:createImage (attachment)
                       print(attachment.name);
                       local thisImage = display.newImage("examples/spineboy/images/" .. attachment.name .. ".png");
                       return thisImage
                 end
                 enm.group.x = _W/2
                 enm.group.y = _H/2
                 enm.group.num = 1
                 enm.group.pause = "no"
                 enm.flipX = false
                 enm.flipY = false
                 enm.debug = false 

---

 Omit or set to false to not draw debug lines on top of the images.
                     enm:setToSetupPose()
                     

                 local stateData = spine.AnimationStateData.new(skeletonData)
                 stateTable[num] = spine.AnimationState.new(stateData)
                 
                 enmDISgroup:insert(enm.group);
                 
                 return enm;
   end

    During the game time I call for function:   "enmTable[1] = spwnEnm("spineboy", 1);"
    I also sets it's animation : "stateTable[1]:setAnimationByName(0, "jump", true, 0);"
    and at ENTERFRAME function i call for:  
  [code]for st=1, #stateTable, 1 do
         if(stateTable[st]~=nil) then   
            stateTable[st]:update(delta)
            stateTable[st]:apply(enmTable[st])
            
            enmTable[st]:updateWorldTransform()
         end
      end

[/code]

 In other parts of the code I call for changing attachments (for e.g: changing a shirt, or adding a hat):
 "enmTable[1]:setAttachment("hat", "hat");"

 My question

Is this way afficient or can it cause problems with memory and performance?
I mean what other way can I use to make it better? because right now it's working fine.

Thanks ahead, Saiphan.
