How to use gotoandplay scene link using class property (external code.as)

[71081]

Hello

I am using ‘gotoandplay’ scene by scene link using this code. If I use this in the same time line (internal), it’s working properly but when I use this code in as a class, I got this error

Call to a possibly undefined method MovieClip.

I use this code in time timeline

b_enter.addEventListener(MouseEvent.CLICK, fl_ClickToGoToScene_enter1);

function fl_ClickToGoToScene_enter1(event:MouseEvent):void

{

            MovieClip(this.root).gotoAndPlay("p menu", "Menu");

}

I use this code in class

package  {

            import flash.display.SimpleButton;

            public class next extends SimpleButton {

                        public function next() {

                                    // constructor code

                                    MovieClip(this.root).gotoAndStop("p2", "page2")

                        }

            }

}

u can download the flash file using this link

in your class file import the movieclip class:

import flash.display.MovieClip

I need this code in button. Because Im using button stages as well (up, over, down, hit)

[kglad]

you'll still need to import the movieclip class.  and you'll need to use an addedtostage listener before trying to reference the root.

You mean like this

package  {

          import flash.display.SimpleButton;

          import flash.display.MovieClip;

          public class next extends SimpleButton {

                    public function next() {

                              // constructor code

                              MovieClip(this.root).gotoAndStop("p2", "page2");

                              //pages.gotoAndPlay("p2", "page2");

                    }

          }

}

When I use this,  buttons its disappear and nothing happened

[kglad]

:

package  {

          import flash.display.SimpleButton;

          import flash.display.MovieClip;

  import flash.events.Event;

          public class next extends SimpleButton {

                    public function next() {

                              // constructor code

//this.addEventListener(Event.ADDED_TO_STAGE,init); // actually, you don't want this.  you probably want:

this.addEventListener(MouseEvent.CLICK,clickF);

}

private function clickF(e:MouseEvent):void{

                              MovieClip(this.root).gotoAndStop("p2", "page2");

                              //pages.gotoAndPlay("p2", "page2");

                    }

          }

}

When I use this,  buttons its disappear and nothing happened

I got this compiler error

Type was not found or was not a compile-time constant: MouseEvent

[kglad]

change Event to MouseEvent in the import statement.

i use nextScene code but haveing problem

package  {

                    import flash.display.SimpleButton;

                    import flash.display.MovieClip;

                    import flash.events.MouseEvent;

          public class np extends SimpleButton {

                    public function np() {

                                        this.addEventListener(MouseEvent.CLICK, fl_ClickToGoToNextScene);

                                        }

                                        private function fl_ClickToGoToNextScene(e:MouseEvent):void{

                                                  MovieClip(this.root).nextScene(),gotoAndStop(1);

                    }

          }

}

[kglad]

your last line of code makes no sense.  it should probably be:

MovieClip(this.root).nextScene();

or

MovieClip(this.root).gotoAndStop(1);

p.s. please mark helfpul/correct responses.

[71081]

if i want to go next scene specific label, then code what will be?

[kglad]

MovieClip(this.root).gotoAndStop("your frame label");  // you can use gotoAndStop("your frame label", "your scene name") but there's no point if you use scene names if you use frame labels.

[71081]

I want to use nextscene and gotoandplay together

Something like this but it’s not working properly

MovieClip(this.root).nextScene(),gotoAndStop (“frame label”);

For exemple:

always go to next scent frame number 10 or frame label play

[kglad]

you can't use duplicate frame labels so using frame numbers:

this.addEventListener(Event.RENDER,renderF);

stage.invalidate();

this.nextScene();

function renderF(e:Event):void{

this.gotoAndStop(10);

}

i try this code but got this compiler error

Type was not sound or was not compile-time constant:Event

package  {

                    import flash.display.SimpleButton;

                    import flash.display.MovieClip;

                    import flash.events.MouseEvent;

                    public class np extends SimpleButton {

                    public function np() {

                                this.addEventListener(Event.RENDER,renderF);

                                stage.invalidate();

                                this.nextScene();

                                          function renderF(e:Event):void{

                                          this.gotoAndStop(5);

                                }

                    }

          }

}

[kglad]

import the Event class:

import flash.events.Event;

[71081]

itry but got this error

Call to a possibly undefined method nextScene through a reference with static type np.

package  {

                    import flash.display.SimpleButton;

                    import flash.display.MovieClip;

                    import flash.events.MouseEvent;

                    import flash.events.Event;

                    public class np extends SimpleButton {

                    public function np() {

                                this.addEventListener(Event.RENDER,renderF);

                                stage.invalidate();

                                this.nextScene();

                                          function renderF(e:Event):void{

                                          this.gotoAndStop(5);

                                }

                    }

          }

[kglad]

oops, i didn't notice you were trying to add that code in a button class and were nesting named functions.  use:

package  {

                    import flash.display.SimpleButton;

                    import flash.display.MovieClip;

                    import flash.events.MouseEvent;

                    import flash.events.Event;

                    public class np extends SimpleButton {

                    public function np() {

this.addEventListener(Event.ADDED_TO_STAGE,init);

                    }

private function init(e:Event):void{

MovieClip(this.root).addEventListener(Event.RENDER,renderF);

                                this.stage.invalidate();

                                MovieClip(this.root).nextScene();

}

private function renderF(e:Event):void{

                                          MovieClip(this.root).gotoAndStop(5);

                                }

          }

}

[71081]

got this output ERROR

:

package {

    import flash.display.SimpleButton;

    import flash.display.MovieClip;

    import flash.events.MouseEvent;

    import flash.events.Event;

    public class np extends SimpleButton {

        var _root:MovieClip;

        public function np() {

            this.addEventListener(Event.ADDED_TO_STAGE,init);

            this.addEventListener(MouseEvent.CLICK,nextF);

        }

        private function init(e:Event):void{

            _root = MovieClip(this.root);

        }

        private function nextF(e:MouseEvent):void{

            _root.addEventListener(Event.RENDER,renderF);

            stage.invalidate();

            _root.nextScene();

        }

        private function renderF(e:Event):void {

            _root.gotoAndStop(5);

        }

hi dear i try this code but got output error

TypeError: Error #1009: Cannot access a property or method of a null object reference.

[kglad]

click file>publish settings>swf and tick "permit debugging". retest.  the problematic line number will be in the error message.

copy and paste the error message here and indicate which line of code is indicated in the error message.
