problem with storyboard duplicating objects

[elpilotojavier]

Hi,

I have a problem with storyboard, when I implement storyboard in one of my projects, two of the physical objects duplicate themselves (the rest of the objects stay fine).

The same project without storyboard works fine (no duplication).

Any help, please?

This is the code for one of the objects:

local indicator=display.newCircle( 100, 100, 20 )

–indicator:setReferencePoint(display.CenterReferencePoint)

indicator.x=200

indicator.y=0

physics.addBody(indicator,“dynamic”,{ density = 1.0, friction = 0.3, bounce = 0.2, radius = 25 })

indicator.linearDamping = 0.5

group:insert(indicator)

–indicator.gravityScale = 0.75

indicator.isVisible=false

Where is this code getting executed? 

If it is in enterScene() or willEnterScene() AND if you don’t remove these objects when you leave the scene, they will get made again the next time you come back.

Likewise, if they are created in or as a result of the call to createScene() AND you are not giving them to the scene to control (i.e. not inserting them into the scene’s group, AND if you’re scene gets destroyed, then the next time you come back, they’ll get made again.  However, since the scene didn’t control them, it didn’t delete them last time and now you have two.

Whatever, the case, please show us the whole code snippet including the calls the scene callbacks like createScene(), enterScene(), etc.  The code above doesn’t give enough context to figure out the problem.

Also, if you can please use the code formatter (see the icon at the top of the editor like this: < > ). Your snippet is small and therefore legible, but if you drop a large bit of code it will be hard to read in text format.

Well, all the code is being executed in

function scene:createScene( event)

enterScene() and willEnterScene() are being left empty.

This two lines outside of storyboard events on the top of the page:

local physics = require( “physics” )

physics.start()

The weird thing is that everything is working properly except this two duplicated objects.

I forgot to mention that this is not a problem of the objects not being purged. This happens when I enter the scene for the first time, and this objects only exist in this scene.

And, sorry, I forgot to include the code, note that the duplication occurs when the joystick is moved to control indicator.
