Я делаю так:
Код AS3:
package
{
import flash.display.*;
import flash.events.*;
public class MainClass extends MovieClip
{
public var keyboardControl:KeyboardControl = new KeyboardControl ();
var hero:HeroBase = new HeroBase();
var heroM:HeroMove = new HeroMove();
public function MainClass ()
{
stage.addChild(keyboardControl);
keyboardControl.addEvents();
stage.addChild(hero);
hero.setCoordinates(50,50);
stage.addChild(heroM);
heroM.addEvents();
}
}
}
Код AS3:
package {
import flash.display.*;
import flash.ui.*;
import flash.events.*;
import flash.events.KeyboardEvent;
public class KeyboardControl extends MovieClip {
public var leftKeyIsDown:Boolean=false;
public var rightKeyIsDown:Boolean=false;
public var upKeyIsDown:Boolean=false;
public var downKeyIsDown:Boolean=false;
var keyPressed:int;
var keyReleaseCode:int;
public function KeyboardControl():void {
}
public function addEvents(){
stage.addEventListener(KeyboardEvent.KEY_DOWN, keyPressFunction);
stage.addEventListener(KeyboardEvent.KEY_UP, keyReleaseFunction);
}
public function keyPressFunction(e:KeyboardEvent):void {
keyPressed=e.keyCode;
if (keyPressed==Keyboard.RIGHT) {
rightKeyIsDown=true;
}
if (keyPressed==Keyboard.LEFT) {
leftKeyIsDown=true;
}
if (keyPressed==Keyboard.UP) {
upKeyIsDown=true;
}
if (keyPressed==Keyboard.DOWN) {
downKeyIsDown=true;
}
}
function keyReleaseFunction(e:KeyboardEvent):void {
keyReleaseCode=e.keyCode;
if (keyReleaseCode==Keyboard.RIGHT) {
rightKeyIsDown=false;
}
if (keyReleaseCode==Keyboard.LEFT) {
leftKeyIsDown=false;
}
if (keyReleaseCode==Keyboard.UP) {
upKeyIsDown=false;
}
if (keyReleaseCode==Keyboard.DOWN) {
downKeyIsDown=false;
}
}
}
}
Код AS3:
package
{
import flash.display.*;
import flash.ui.Keyboard;
import flash.events.*;
public class HeroMove extends MovieClip
{
public function HeroMove()
{
}
public function addEvents(){
stage.addEventListener(Event.ENTER_FRAME, everyFrame)
}
public function everyFrame(){
if( keyboardControl.leftKeyIsDown){}
if( keyboardControl.rightKeyIsDown){}
if( keyboardControl.upKeyIsDown){}
if( keyboardControl.downKeyIsDown){}
}
}
}
и при компиляции мне ругаются что keyboardControl.leftKeyIsDown - неизвестное свойство. Как мне его сделать известным?
