RE: [flasher] MovieClip load and unload

[Bill Gunter]

Todd-


There are two different ways you can approach this, 1: you can use the load

movie command and load external files, and 2: you can use the attach movie

command and load internal movieclips into a blank movieclip wherever you

want in your file.


The first approach using loadMovie is done by making all of the content you

want to be loaded into it's own seperate swf(making sure to keep the files

in the same directory as the main file). Loading movies deals with levels

and levels are basically layers for movieclips and or external swf's, it's a

way to keep track of them and organize them. Because of this you must assign

a level to each external file you load so that when you load it, it knows

where to go. The main movie is always going to be on level 0 so you must

load the external file into a level higer than 0(note: only 1 movie can be

loaded into a level at once, if you load more than one it will remove the

old one and replace it with the one you are loading). Once you create your

external files all you have to do is assign the action to a button or

whatever else like so:


on(release){

	loadMovieNum("nameofmovie.swf", 2)

}


namofmovie.swf is the external files name and 2 is the level you are

assigning the movie to.


To unload that movie just use the unload movie statement:


on(release){

	unloadMovieNum(2)

}


by unloading 2 you are unloading the movie that is sitting in level 2.




The second option you have is to use the attach movie script which can be a

little more tricky, I suggest you not use this if you are not comfortable

with scripting. To do this you  would load a blank movie clip into wherever

you want the movies to load and give it an instance name like blankclip.

Next go to your library and right click(control click for mac users) on the

movieclips you want to load and select linkage. A dialogue box pops up and

you then need to toggle the export this symbol radio button and name the

clip. When you have finished that you can then assign the attachmovie action

to a button or whatever like so:


on(release){

	_root.blankclip.attachMovie('linkagename', 'instancename', level#)

}


In order to get this script into your actions pallette you will need to

toggle your actions window from normal mode to expert mode and then type

this script into the box by hand for there is no attachmovie command in the

actions menu.

To unload a clip use this:


on(release){

	_root.blankclip.removeMovieClip()

}


That is it, I hope this will help get your project up and running, good

luck.

Subject: [flasher] MovieClip load and unload



Okay, so I'm building an interactive application in Flash 5 and want to use

movie clips instead of scenes for a particular area. In short, I have a case

studies section, and I'd like to have each case study load as a movie clip.


Here's the current set-up. I have a scene called scnCaseStudy. I have the

main navigation fly in -- currently built in the scene, but will be changed

to a movie clip, as this navigation will grow. Then I have a MC (movie clip)

for the animation sequence of the navigation for the Case Studies placed in

the scnCaseStudy. This MC is called mcCaseStudyList


In the MC mcCaseStudyList, I have all the different case studies as MCs.

Again, I'll be updating these MCs to use scrolling text boxes, but for now

they're static. Hence, the reason for making them a MC.


What I'm trying to do is have the mcCaseStudyList load and unload the

different MCs (e.g. mcCaseStudy01, mcCaseStudy02, mcCaseStudy03). I've tried

the loadMovie, unloadMovie command, but it unloaded the main movie. This may

have been because I set the variable level to 0. Should I load the MCs at

their own level, or level 1 to prevent this? Will this allow me to load

mcCaseStudy01 at level 1? Then creating a button, which has the action,

unloadMovie at level 1, will this unload the movie mcCaseStudy01, returning

me to the stage of the main scene in mcCaseStudyList?


Right now, I have a button set to play a current scene in mcCaseStudyList,

which is just the list w/o any MCs loaded. The drawback is, this isn't in

the case study MCs, it's in the mcCaseStudyList, placed ontop of the MCs

(e.g. mcCaseStudy01, mcCaseStudy02, mcCaseStudy03).


Thanks!
