If mc._x = __ not working

Hey I'm trying to run a code which motion tweens an mc off the stage, and only then does it tween an mc onto the stage. Im using the following script where _x = -200 is the position when it is off the stage.

topbar_box.onRelease = function() {
var moveSectionX:Tween = new Tween(_root.content.section_holder, "_x", Strong.easeIn, 61, -200, 2, true);
var moveSectionY:Tween = new Tween(_root.content.section_holder, "_y", Strong.easeIn, -25, 768, 2, true);
if (_root.content.section_holder._x = -200) {
loadMovie("about_section.png", _root.content.section_holder);
var moveSectionX:Tween = new Tween(_root.content.section_holder, "_x", Strong.easeOut, 500, 22, 2, true);
var moveSectionY:Tween = new Tween(_root.content.section_holder, "_y", Strong.easeOut, -500, -7, 2, true);

It loads the new file into the mc before it has a chance to move off the stage. I tried loading the new file into a new empty mc, and that works, however the new file comes onto the stage too early and doing it this way would leave me with too many empty mcs to load files into.

Cheers

For anyone reading this I ended up using setInterval to wait a certain time until it executed the next script.

myFutureFunction = function() {

// setInterval will repeat every XX seconds if we don't clear it here...

clearInterval(handle);

// future lines of code go here...

}


// execute some code here...

// Then use setInterval to schedule myFutureFunction 4 seconds in the future

handle = setInterval(myFutureFunction, 4*1000);

you must define that method in the topbar_box function because you made moveSectionX local to your function.

if you needed to check that _x property after the tween was complete you should just use the onMotionFinished() method of the tween class.

Good thinking. It doesn't seem to be working though. What's new. Even though I have another file where it uses the onMotionFinished method and works...

that _x property is probably not exactly -200. use Math.abs() to check if the _x property is close enough to -200 to trigger your load.

hey no luck their eitehr kglad... i did it like: if (_root.content.section_holder._x == Math.abs(-200)) {

ha so you have to download it hey...
i put it in the First Run > Classes > FP8 folder,
called import FP8.caurina.transitions.*;
but it still doesn't work?
still im curious if there is a solution using time...

use double equal (==) to test for equality. and use the attach code option to display code in this forum.

>>if (_root.content.section_holder._x = -200) {

Here you're assigning -200 to _x - you want a double-equal to test for
equality:

if (_root.content.section_holder._x == -200) {

However this still isn't going to work, as your test only happens one time,
and your clip isn't going to be at -200 until the tween finishes. I don't
use the built in tweening stuff, but you may want to look at something like
Tweener, or Fuse where you can define a callback to execute once the tween
completes:

Tweener.addTween(_root.content.section_holder, {_x:-200, time:2,
transition:"strong.easein", onComplete:offStage});

function offStage(){
//transition completed
}

Hey, what's Tweener? There is nothing in help, and I tired the following script but it didnt work:

import mx.transitions.Tween;
import mx.transitions.easing.*;

function offStage() {
loadMovie("about_image.png", _root.content.image_holder);
var moveImageX:Tween = new Tween(_root.content.image_holder, "_x", Strong.easeOut, Stage.width, 66, 3, true);
var moveImageY:Tween = new Tween(_root.content.image_holder, "_y", Strong.easeOut, 630, 150, 3, true);
unloadMovie(_root.content.section_holder2);
}

topbar_box.onRelease = function() {
Tweener.addTween(_root.content.section_holder,{_x:-200, time:2, transition:"strong.easein", onComplete:offStage});
Tweener.addTween(_root.content.section_holder,{_y:768, time:2, transition:"strong.easein"});
};

What if you did it so that instead of checking for _x it waited for 2secs - or any defined time - since we know it will take 2 seconds to complete the transition...
