Dear masters,

I need your help, I want to delete a movieclip when I press delete on keyboard. but only delete an active movieclip. I use this code before but didn't work.

import flash.display.MovieClip;

import flash.events.MouseEvent;

import flash.events.Event;

import flash.printing.*;

import fl.transitions.*;

function item_onMouseDown(event:MouseEvent):void {

event.currentTarget.startDrag();

}

function item_onMouseUp(event:MouseEvent):void {

event.currentTarget.stopDrag();

}

process_btn.addEventListener(MouseEvent.CLICK, process);

function process(event:MouseEvent):void

{

   

    panjang = Number(panjang_txt.text);

    lebar = Number(lebar_txt.text);

    var mc3:MovieClip = new MovieClip();

    mc3.buttonMode = true;

    mc3.addEventListener(MouseEvent.MOUSE_DOWN, tool.select);

    var randomColours2:int = Math.floor(Math.random() * 0xFFFFFF);

    mc3.graphics.lineStyle(4, 0x000000, .5);

    mc3.graphics.beginFill(randomColours2, .2);

    mc3.graphics.drawRect(0, 0,(panjang/10)/1.3, lebar/10);

    mc3.graphics.endFill();

    mc3.x = 20;

    mc3.y = 250;

    addChild(mc3);

    mc3.addEventListener(MouseEvent.MOUSE_DOWN, item_onMouseDown);

    mc3.addEventListener(MouseEvent.MOUSE_UP, item_onMouseUp);

   

    //action for delete active movieclip

    mc3.addEventListener(KeyboardEvent.KEY_DOWN, onKeyPressed);

    function onKeyPressed(event:KeyboardEvent):void

    {

           if (event.keyCode==Keyboard.DELETE) {

               removeChild(mc3);

       }

    }

   

}


please help me to solve this problem,

regards,

use:

import flash.display.MovieClip;

import flash.events.MouseEvent;

import flash.events.Event;

import flash.printing.*;

import fl.transitions.*;

var mc3:MovieClip;

function item_onMouseDown(event:MouseEvent):void {

event.currentTarget.startDrag();

}

function item_onMouseUp(event:MouseEvent):void {

event.currentTarget.stopDrag();

}

process_btn.addEventListener(MouseEvent.CLICK, process);

function process(event:MouseEvent):void

{

    if(!mc3){

    panjang = Number(panjang_txt.text);

    lebar = Number(lebar_txt.text);

   mc3 = new MovieClip();

    mc3.buttonMode = true;

    mc3.addEventListener(MouseEvent.MOUSE_DOWN, tool.select);

    var randomColours2:int = Math.floor(Math.random() * 0xFFFFFF);

    mc3.graphics.lineStyle(4, 0x000000, .5);

    mc3.graphics.beginFill(randomColours2, .2);

    mc3.graphics.drawRect(0, 0,(panjang/10)/1.3, lebar/10);

    mc3.graphics.endFill();

    mc3.x = 20;

    mc3.y = 250;

    addChild(mc3);

    mc3.addEventListener(MouseEvent.MOUSE_DOWN, item_onMouseDown);

    mc3.addEventListener(MouseEvent.MOUSE_UP, item_onMouseUp);

    //action for delete active movieclip

    mc3.addEventListener(KeyboardEvent.KEY_DOWN, onKeyPressed);

}

    function onKeyPressed(event:KeyboardEvent):void

    {

           if (event.keyCode==Keyboard.DELETE) {

               removeChild(mc3);

       }

    }

sorry kglad, it still cannot solve the problem.

after I take the variable mc3 in the outside, the function cannot delete the child of mc3 and cannot draw more than one movieclip like before.

Keyboard events shouldn`t be added to MovieClips but to the stage.

stage.addEventListener(KeyboardEvent.KEY_DOWN, onKeyPressed);

you could create a dynamic property for your MovieClip, that stores an activated state

mc3 = new MovieClip();

mc3.active = false;

then setting the property to true, if it is dragged

back to false, when it is dropped and then in the Listener

    function onKeyPressed(event:KeyboardEvent):void

    {          

         for(var i:uint= 0;i<this.numChildren-1;i++){

                 if(this.getChildAt(i) .active){

                     removeChild(getChildAt(i));

                 }

             }

       }

another Problem is that you add 2 conflicting functions

mc3.addEventListener(MouseEvent.MOUSE_DOWN, tool.select);

...

mc3.addEventListener(MouseEvent.MOUSE_DOWN, item_onMouseDown);

Why do you do that and what does tool.select?
