It would be amazing if someone could expand on the current answer, Thanks.

Line 22 1119: Access of possibly undefined property CharacterX through a reference with static type flash.display:DisplayObject.
I'm trying to set a variable for the object shark, that is already defined in the object character First time using setters in flash, so I might not be doing this right.
code I'm using to set the variable I tried to comment out the stuff I thought was irrelevant to this issue, not actually commented out in real code.
var character:Character;
//var bullet:Bullet=null;
//var bullets:Array = new Array();
//var enemies:Array = new Array();
//character=new Character(bullets);
addChild(character);
var shark:Shark=new Shark();
addChild(shark);
//var enemy:Enemy=null;
////var i:int;
//for (i=0; i<10; i++) {
//enemy = new Enemy(Math.random()*stage.stageWidth, Math.random()*stage.stageHeight);
//addChild(enemy);
// enemies.push(enemy);
//}
//stage.addEventListener(Event.ENTER_FRAME, colTest);
//function colTest(e:Event ):void {
// if(character.hitTestObject(turtle)){
// character.gotoAndStop("Turtle");
// }
//}
shark.setT(character.x, character.y)
class in which I'm attempting to define a variable using the function above.
package
{
import flash.display.*;
import flash.events.*;
public class Shark extends MovieClip
{
var CharacterX:Number = 0;
var CharacterY:Number = 0;
public function Shark()
{
this.x = 300;
this.y = 200;
addEventListener(Event.ENTER_FRAME,playGame);
}
public function setT(characterx:Number,charactery:Number){
CharacterX = characterx - this.x;
CharacterY = charactery - this.y;
}
function playGame(event:Event):void
{
var ease:int = 20;
var speed:int = 10;
var targetX:int = root.CharacterX - this.x;
var targetY:int = root.CharacterY - this.y;
var rotation = Math.atan2(targetY,targetX) * 180 / Math.PI;
cut code off here, didn't want to make a code dump can get you anything that might be relevant just ask.
Here is a pastebin of all of the code if it might help,
Character class
Let me start by saying I can't spot the exact problem here, but I have some ideas. Your error 1999 says that something of the type display object is trying to change your variable. This happens a lot when you use parent.myMethod() because parent is typed as display object. You would fix this by typecasting like (parent as MovieClip).myMethod
In your case I don't see the exact source of this problem. But you could try using this.characterX in your setT function
