/* Click to Go to Frame and Stop

****** I Had 5 type of puzzle and each puzzle is located in among 5 frame . When i play the swf , the error #1009 occur. I realize that i needed to remove the event listener .

****** For my next frame

stage.addEventListener(Event.ENTER_FRAME,EntFrame);

function EntFrame(e:Event):void

if i put the same code it will become duplicate .

should i just put like this ?

stage.addEventListener(Event.ENTER_FRAME,EntFrame2);

function EntFrame2(e:Event):void

[kglad]

use

stage.removeEventListener(Event.ENTER_FRAME,EntFrame)

to remove an event listener.

Where do i need to put that ?

[kglad]

wherever and whenever you want to remove the listener.

if that's before changing frame, add it to the code that changes the frame.

*/

movieClip_3.addEventListener(MouseEvent.CLICK, fl_ClickToGoToAndStopAtFrame);

function fl_ClickToGoToAndStopAtFrame(event:MouseEvent):void

{

gotoAndStop(2);

}

put the code here ?

[kglad · Accepted solution]

yes, that looks like a good spot:

movieClip_3.addEventListener(MouseEvent.CLICK, fl_ClickToGoToAndStopAtFrame);

function fl_ClickToGoToAndStopAtFrame(event:MouseEvent):void

{

stage.removeEventListener(Event.ENTER_FRAME,EntFrame)

gotoAndStop(2);

}

[asrolr82301770]

it was correct .thank you very much

now at the frame 2 i use the same event listener but when export pdf it say duplicate

stage.addEventListener(Event.ENTER_FRAME,EntFrame);

function EntFrame(e:Event):void

{

// puzzle 5

puzzle5.addEventListener(MouseEvent.MOUSE_DOWN, fl_ClickToDrag_14);

function fl_ClickToDrag_14(event:MouseEvent):void

{

puzzle5.startDrag();

}

stage.addEventListener(MouseEvent.MOUSE_UP, fl_ReleaseToDrop_14);

function fl_ReleaseToDrop_14(event:MouseEvent):void

{

puzzle5.stopDrag();

}

if (target5_mc.hitTestObject(puzzle5.tar5_mc))

{

puzzle5.x = 313.65;

puzzle5.y = 169.45;

}

//puzzle 6

puzzle6.addEventListener(MouseEvent.MOUSE_DOWN, fl_ClickToDrag_15);

function fl_ClickToDrag_15(event:MouseEvent):void

{

puzzle6.startDrag();

}

stage.addEventListener(MouseEvent.MOUSE_UP, fl_ReleaseToDrop_15);

function fl_ReleaseToDrop_15(event:MouseEvent):void

{

puzzle6.stopDrag();

}

if (target6_mc.hitTestObject(puzzle6.tar6_mc))

{

puzzle6.x = 423.05;

puzzle6.y = 174.80;

}

//puzzle 7

puzzle7.addEventListener(MouseEvent.MOUSE_DOWN, fl_ClickToDrag_16);

function fl_ClickToDrag_16(event:MouseEvent):void

{

puzzle7.startDrag();

}

stage.addEventListener(MouseEvent.MOUSE_UP, fl_ReleaseToDrop_16);

function fl_ReleaseToDrop_16(event:MouseEvent):void

{

puzzle7.stopDrag();

}

if (target7_mc.hitTestObject(puzzle7.tar7_mc))

{

puzzle7.x = 315.15;

puzzle7.y = 276.50;

}

// puzzle 8

puzzle8.addEventListener(MouseEvent.MOUSE_DOWN, fl_ClickToDrag_17);

function fl_ClickToDrag_17(event:MouseEvent):void

{

puzzle8.startDrag();

}

stage.addEventListener(MouseEvent.MOUSE_UP, fl_ReleaseToDrop_17);

function fl_ReleaseToDrop_17(event:MouseEvent):void

{

puzzle8.stopDrag();

[asrolr82301770]

i mean export swf

[kglad]

you can't use the same function name more than once.  how would the animate program know which of the two functions to call?

stage.addEventListener(Event.ENTER_FRAME,EntFrame_2);

function EntFrame_2(e:Event):void{

gotoAndStop(3)

}

[asrolr82301770]

Thank you veryy muchh . You've solved my problem .

[kglad]

you're welcome.

Test Movie terminated.

why this appear continuously on my output ?

[kglad]

the first error is occurring because frame 131, line 84 is referencing a non-existent object.
