    refreshing without looping???

      Hello everyone - i am trying to build something using mostly code but i am having a SERIOUS issue with the fact that i can only get it to work properly if i have it spanning 2 frames with my code on the first, and code on frame 2 simply "gotoAndPlay(1);" to loop it so my script keeps being rechecked for changes in variables. Because i have things trigger when variables change...heres what i mean.

      new Tween(usr_matt, "_alpha", Strong.easeOut, 100, 0, 2, true);

      which should trigger when a loaded swf sets the global logged variable to true. But unless i loop the timeline to keep checking the variables nothing happens because it doesnt know its changed, it doesnt watch/listen to it. the problem with this in this case is everytime the timeline loops it reinitilizes that if statement and starts the tween all over again, meaning it never fades because it keeps restarting the fade!

      another example being -

      if (usr_name.text=="Matt"&&usr_pass.text=="test"){

      here i disable the submit button until the fields match, so again i needed to loop the timeline to keep the variables updating to see when the fields did match! unfortunatly that messed up the next bit of code so i had to impliment a work around for it

      usr_name.text = des_usr;

      where i have a text field that inherits its .text value initially from a global variable, but then in order (just in case) the user wants to change the value (if they dont like the default) i needed to break to loop by making a whole new variable to cancel it out once its been triggered once!

      My head is just starting to hurt with ALL the variables im assinging and i havnt really even dont anything yet but make a popup box and pass some variables...but christ...i cant have every timeline on a loop that would bog everything down SO much, eventually i will have 4-5 loaded swf's on at once, all looping? i dont think so...

      There HAS to be a better way to do it, to assing certain If statements to constatly update without looping the whole damn thing!

          you can use the watch() function to check when variables change and trigger actions when they do.

            thank you kglad for the quick response! would you mind just a quick "how" say with one of the example i provided that would be great! obviously i have never heard of the watch function and it sounds like exactly what im looking for!, again - thank you!

              if you associate variables with your textfields, you can use:

                I will give that a go - sounds promising! and i should be able to do that for all my vars?

                  yes. you will probably want to use different functions for the various tasks, but any variable can be watched.

                  object properties can be watched, too but i had trouble setting up a watch method for the text property of a textfield. that's why i resorted to using a variable associated with a textfield.

                    Ah well you just answered my next question - i was going to say can i not just get it to watch the .text property instead of putting it to a variable first. No matter though i think i can sort that out. by different functions you do mean

                    loginCheck = function (prop, oldVal, newVal

                    changing the loginCheck name right? by the way what are the handlers on there? prop, oldVal, newVal - what are they each doing?

                      okay next question - how am i appending the text fields .text property to the variables usrNameVar - usrPassVar? because again - it wont update the variable while i type, only when its reloaded...so...are we not just back to where we started?

                        if your textfields are created in the authoring environment check the properties panel. there's a Var: input region where you can enter a variable name. or you can use the variable property of textfields to add the variable name using actionscript.

                        for example:

                            loginCheck = function (prop, oldVal, newVal) {
                            if (usrNameVar == "Matt" && usrPassVar == "test") {
                            submit.enabled = true;
                            } else {
                            submit.enabled = false;
                            return newVal;
                            watch("usrNameVar", loginCheck);
                            watch("usrPassVar", loginCheck);

                            does absolutly nothing...doesnt disable the box or anything...

                                  the dreaded components. you're using a textinput component. that's not the same as an input textfield. in particular, there's no variable associated with a textinput component.

                                  anyway, here's a working version of your login.fla. i did not edit desktop.fla:

                                    Thank you so much kglad - truely a god amoungst mortals. if you dont mind me asking - did you have messenger or anything like that?

                                    as well - the last line of code "submit.enabled = 0" where/what is that doing? the rest is beautiful!

                                      the last line is to make the submit button disabled by default. it's only enabled when the correct user name/pass are entered. that code can be removed.

                                      p.s. i have no messenger clients. i have an email link at my website:

                                        Okay I Do appreciate all you have don VERY much, and you are by no means obligated to help me any further if you dont wish, please dont think i am just tryig to get you to do this i really am trying to learn here. I have tried to bring what you did over to my desktop.fla. I was trying to set it up so when you logged in, the variable "_global.logged_usr" would represent who logged in, it would then be collected by the desktop.fla and do a little animation thing. I did this:

                                        log = new Object();
                                        log.change = function(eventObject:Object) {
                                        if (_global.logged_usr.text.toLowerCase() == "matt") {
                                        new Tween(usr_matt, "_alpha", Strong.easeIn, 100, 0, 3, true);

                                        logged_usr.addEventListener("change", log);

                                        I get no response from the trace so its not even getting to that point. anyideas where i have gone wrong? it looks fine to me based on what we did in the previous movie. and we cant blame components this time neither! lol.

                                          you shouldn't prefix a variable name with _global (or var) unless you are assigning a value to it. when you're retrieving a value, the prefix should not be used.

                                          so, in login.fla you correctly use

                                          _global.logged_usr = usr_name.text;

                                          removing the _global prefix from desktop.fla may be all you need to do. but if that doesn't work, then i'll need to know how these two swfs are related.

                                          for example, do you use loadMovieNum() to load one of them?

                                              oh no, another component.

                                              but using _global in login.fla saves us from using the path _level0.depthChild0.content to your popup. so, the problem isn't the path, it's your attempt to attach a listener to a variable which has some problems.

                                              there's a more direct solution in this situation: you can call a function in your desktop.fla from your submit button in login.fla:

                                                I have been making some progress (even though im sure im doig it all wrong!)

                                                I have run into an issue, i am not trying to add more sets of usernames and passwords to what we alreayd have, unfotunatly its not like i can just add another if statement to the mix, or append whats there with a ||. So again, i am at a loss, no matter what i do it seems to just accept the last once i entered and completly ignores the rest. Thoughts?

                                                  I guess i could copy the lo. change function 5 times...i dont know if that would work...and it certainly doesnt seem practicle, im still have a problem with it taking the most recently added username/pass. I cant see any other way of adding the other than "||" after the first pair really. thoughts?

                                                    Do you have any experience with php/mySQL?

                                                    It sounds like you could use a database to store all of the login data and use php to check if the data entered into the flash form exists in the database , then if it does return yes and if it doesn't return no.

                                                    The do whatever is required after the login depending on the php return.

If i was doing this for a more serious project and needed expandability and such i would ceratinly try to utilize php/mySQL. Fortunatly/unfortunatly this has just been an idea I started off with that has grown (couldnt have gotten where i am now though without kglads help, hes been great! - But thank you flash2koolforskool, i appreciate the thought!

                                                        you can list all your username/password combinations in an array and loop through the array to check if a correct login is recognized.

                                                        but before you go much further, how secure is this supposed to be?

                                                          next thing would be - how on earth do we define all the usrnames and passwrds in a looping array??! im all ears.

                                                            you just need to keep adding [username,passwords] to usrA to authorize more users.

                                                              Okay your going to laugh at me im sure...but i have attatched my code for "desktop.fla" as well as what i got currently for "login.fla" it seems when the button is fired it triggers the the wrong movieclip....as you can see from the code I attatched it works flawleslly with just the 1 MC on the stage coded. But as soon as i add the next one "under the //----ryan---- comment line - no matter who i login be it matt or ryan it fires ryans animations. I have 3 more to add after ryan and i tried it and in the case when all 5 are in, no matter who i login is it fires the last one all the time. I am sure it has something to do with my code structure, i have just been copying the first MC's code and changing the references to it, to the new one as i go...you will see...what have i done wrong? i know its a Sod.

Honestly! i was going to give you an email but i was wearing of just using that flash form (didnt know when/if you would get it) Again - thank you so much! i have always been able to use flash and write code, not well by any means, but your really helping me take it to the next level for me and thats great because i love this stuff! Thank you again!

I am doing my best to look it all over and see what you have done to tidy it up! looks so much cleaner!....but....it doesnt work. Im sure its hard writing the code without knowing how it will work lol, you've done amazing! i provided a link at the bottom to the fla's to see for yourself. For one, (and i dont know how to adapt the code for this) when you login as say matt, the "matt box" should fall from its current y position to the specified, while all others (4 of them) fade out. they are all in a column though so i dont think thats going to work like that, as the current tween class is specifiying an y value to start from (in this case 48, which is the matt box y value, the ryan y value may be 130 and so forth...
                                                                      "var drop:Object = new mx.transitions.Tween(usrName, "_y", mx.transitions.easing.Bounce.easeOut, 48, 380, 2, true);"
                                                                      as well - give it a test run and see for yourself what goes on - i cant account for it, maybe you can shine some light?

                                                                      again kglad - i feel really bad for constantly asking you to save me, but i really am getting there (especially with that last bit of cleaned up code!) i have a tendency to make huge long overredundant scripts so this should help me collapse things a little!.

                                                                      Thanks again good Sir,

I am having problems with this line...

                                                                        new mx.transitions.Tween(usr_matt.logout, "_x", mx.transitions.easing.Bounce.easeOut, 25, 140, 3, true);

                                                                        it seems it only works if i reference it like that, if i cange it to ("usr_"+usrName.logout,) it doesnt work, no matter how i try to reference it, but it works for everything else! go figure :S

                                                                        As well - as i said i want everything but the "usr_"+usrName to fade out (right now its only one that does) now in my head im seeing (and from what ive seen you do) and array will be the way to do it? except somehow exlude usrName?

                                                                        • 34. Re: refreshing without looping???

                                                                            kglad - the movieclip loaders are what load the editlist.swf into the movie...at least that was the plan lol.
