AS3 MOVING OBJECT ON SPECIFIC FRAME - actionscript-3

Question

so i've been working on this game for a week now and i dont have any coding background at all so im trying to find tutorial here and there.. then i come up with this problem ...
so what i wanna do is move the object (CHARA) to the right when i hit frame 80 inside (CHARA,which is a nested movieClip with 99 frames btw ) then move it back to original position when i hit frame 99...
the problem is anything i do doesn't make my object move at all (movieClip still played btw) what did i do wrong here? did i just put the code at the wrong position ?? (CHAR is moved only if i put the code x= directly inside frame 80 but i try using class here)
here is my code,sorry i know its messy its my first code i try my best here
package {
public class Main extends MovieClip {
public var CHARA:CHAR = new CHAR;//my main char
public var rasen:Rasen_button = new Rasen_button;//the skill button
public var NPCS:NPC = new NPC;// the npc
public function Main() {
var ally:Array = [265,296];//where me and my ally should be
var jutsu:Array = [330,180];// where the buttons should be
var enemy:Array = [450,294];//where the enemies should be
addChild(NPCS);
NPCS.x = enemy[0];
NPCS.y = enemy[1];
NPCS.scaleX *= -1;
addChild(rasen);
rasen.x = jutsu[1];
rasen.y = jutsu[0];
addChild(CHARA);
CHARA.x = ally[0];
CHARA.y = ally[1];
rasen.addEventListener(MouseEvent.CLICK, f2_MouseOverHandler);
function f2_MouseOverHandler(event:MouseEvent):void {
CHARA.gotoAndPlay(46); //here is the problem
if (CHARA.frame == 80)
{
CHARA.x = ally[1]; //just random possition for now
}
}
}
}
}
any suggestions?

Answer 1

Your if statement is inside a click handler (f2_MouseOverHandler), so it only gets executed when a user clicks rasen, not necessarily when the playback reaches frame 80. This is a common beginner mistake related to timing and code execution. The most straight forward solution is to write some code that will execute every frame using an ENTER_FRAME handler:
rasen.addEventListener(MouseEvent.CLICK, f2_MouseOverHandler);
function f2_MouseOverHandler(event:MouseEvent):void {
CHARA.gotoAndPlay(46); //here is the problem
// add an ENTER_FRAME handler to check every frame
CHARA.addEventListener(Event.ENTER_FRAME, chara_EnterFrameHandler)
}
function chara_EnterFrameHandler(event:Event):void {
if (CHARA.currentFrame == 80)
{
CHARA.x = ally[1]; //just random possition for now
// remove the ENTER_FRAME after the condition is met
// so it stops executing each frame
CHARA.removeEventListener(Event.ENTER_FRAME, chara_EnterFrameHandler);
}
}
