Trying to figure out relation between classes but getting 1119 error - actionscript-3

Question

This past week I've done some AS3 class research and wrote some code but everytime I reach the point that I need something from another class I keep getting different errors >_<.
now I started from scratch to understand whats going on but even now I can't get it right.please somebody tell me what I'm doing wrong?
my document clas:
package {
import flash.display.MovieClip;
public class main extends MovieClip {
public function main() {
var m23:m22 = new m22;
addChild(m23);
m23.x=100;
m23.y=100;
var k:keyz = new keyz;
addChild(k);
k.x=300;
k.y=300;
}
}
}
my other class:
package {
import flash.display.MovieClip;
import flash.events.MouseEvent;
public class keyz extends MovieClip {
public function keyz() {
addEventListener(MouseEvent.MOUSE_DOWN,ret);
}
private function ret(event:MouseEvent):void {
main.m23.x+=10;
}
}
}
problem line is"main.m23.x+=10;"
thanks you

Answer 1

you can access the object in document class using root reference provided the object is public. Change your document class to
package {
import flash.display.MovieClip;
public class main extends MovieClip {
public var m23:m22;
public function main() {
m23 = new m22;
addChild(m23);
m23.x=100;
m23.y=100;
var k:keyz = new keyz;
addChild(k);
k.x=300;
k.y=300;
}
}
}
And your keyz class should be,
package {
import flash.display.MovieClip;
import flash.events.MouseEvent;
public class keyz extends MovieClip {
public function keyz() {
addEventListener(MouseEvent.MOUSE_DOWN,ret);
}
private function ret(event:MouseEvent):void {
(root as MovieClip).m23.x+=10;
}
}
}
Hope it helps.
