[Golist] loop error

[Christopher Wilson]

That's cool, well if you determine that this is where the error was arising from, maybe you could add event listeners that would be certain all those tweens are absolutely complete before running the function with the visible change.  Maybe Hydrotween has an onComplete method...

Good luck!

Thanks again,.
I'm using visible=false to disable any mouseEvents I've got on them.  But I guess I can workaround by just removing the listeners instead and using alpha = 0 with that,...
I will try that out,...

Thanks for your attention to my questions so quickly,...

Sorry bro, I haven't touched the GoASAP, Hydro classes at all.  By the name of the class "HydroSequence", I assume it is designed to run all those tweens in sequence one after the other.  However, your trace function might not be handled in the same way because it does not have the properties like a displayObject would, so they may get handled generically in the object parsing.  Generic Objects in AS are not handled sequentially.  There is nothing unusual or contingent on timing in the properties your are effecting with the sequence.  However, if the function hideOthers or hider actually sets a displayObject to visible=false, it's standard properties will become inaccessible after that.  If you are using visble=false, try changing it to alpha=0 instead and see if that does the trick of relieving the error.

Thanks Wilson for the input, but I think the issue is one sequence I'm running,...

It seems to be playing out of order.
Any ideas what am I doing incorrectly here?

When I trace out some items like so :

var goItem4 : HydroSequence = new HydroSequence(

[ { func:trace, args:["11"]},
{ target:tmpClicked,       scaleX:1.8,        scaleY:1.8, x:650, y:150,            duration:catCloudZoomDuration,               easing:Quintic.easeOut },
{ target:tmpOther1,        scaleX:.5,         scaleY:.5, alpha:0,                     duration:catCloudZoomDuration/2,              easing:Quintic.easeOut },
{ target:tmpOther2,        scaleX:.5,         scaleY:.5, alpha:0,                     duration:catCloudZoomDuration/2,              easing:Quintic.easeOut },
{ target:tmpOther3,        scaleX:.5,         scaleY:.5, alpha:0,                     duration:catCloudZoomDuration / 2,             easing:Quintic.easeOut },
{ func:trace, args:["22"]}],

[ { func:hideOthers, delay: 0, args:[tmpClicked] } ],

[ { func:hider, delay:.2 } ]

)

My trace statements fire
22
11

wha????????

Should I be setting duration props in the func calls?

I'm due to launch today, and this one bug keeps randomly popping up, and I can't even recreate it consistently.
I am noticing that my hydro sequences are all firing out of order though....
Any insight or help would be greatly appreciated.

Thanks



Shane

As you know, the error is from attempting to change a property of an object that has not been instantiated.  Somewhere in your sequence of events there is an object that is not ready to be manipulated.  You might want to try adding a listener for the ADDED_TO_STAGE event that all Sprites dispatch.  This can add an extra layer of insurance that the object you are messing with is ready to be tweened or whatever you're doing.

Any one encountered this error from Go and HydroTween.

TypeError: Error #1009: Cannot access a property or method of a null object reference.
            at MethodInfo-1412()
            at Function/http://adobe.com/AS3/2006/builtin::apply()
            at com.hydrotik.go::HydroTween/onUpdate()
            at org.goasap.items::LinearGo/update()
            at org.goasap::GoEngine$/update()


I have had everything working well and this is now randomly cropping up,...
I under stand the 1009 error, but I cannot track it down, that's why I am asking about this for GO or Hydro...
or is this my mistake somewhere,..?

btw, once triggered, this error endlessly loops? It's not a onetime throw.

Thanks...

Shane
