Passing variables into a class in .as file

Hi.

This may be a simple question but not sure how to do it.

I have purchased a video player that derives all its code from external .as files (stored in com/flashaman/Videoplayer.as). Problem is that it's designed to be for a single video file where I would like to use multiple instances of the player in various areas of my flash file.

The code within the Videoplayer.as file is:

Actionscript Code:

package com.flashaman.videoplayer
{
    public class Videoplayer extends MovieClip
    {       
        // - VARIABLES
        private var _playerWidth:int = 640;
        private var _playerHeight:int = 390;
        private var _currentVideo:int = 0;
        
        private var _videoURL:String = "video/showreel.mov";
        private var _imageURL:String = "image/showreel.jpg";

Specifically the only variables I need to modify are _videoURL and _imageURL. How can I modify these files from within my Flash file?

I am not good with Classes, but try referring it to a variable in your Flash. Change your variables in your .as files to this:

Actionscript Code:

private var _videoURL:String = _root.video_url;
private var _imageURL:String = _root.image_url;

and then in your Flash, type this in the Main Stage, on a Frame:

Actionscript Code:

video_url = "video/showreel.mov";
image_url = "image/showreel.jpg";

I tried something similar, it worked, but not flawlessly. My class constructor was called twice, and the first time it didn't register the variables in my Flash file, but it did the next time. Why that happened, is because the .as file was loaded BEFORE the Flash file's content.

This is not going to work like this.

What I would suggest is to make a setter in that so that you can change it from anywhere you want.

To expand on setters, this is how you would define it in your class:

Code:

---

public function set videoURL(videoURL:String):void{
_videoURL = videoURL
}

---

So with that, you can reference the holder for the VideoPlayer and edit it like you would any other property, like x or width.

E.g.
(For this, I'm just using "videoPlayer" as an instance of the VideoPlayer class you're using)

Code:

---

videoPlayer.videoURL = "new URL here";

---

Thanks, Danny22, was helpful for me as well :)

Thanks for the suggestions thus far - I have created new projects to play with the methods discussed, however to make things more challenging the Videoplayer class discussed above is not instantiated through a constructor, rather through linking a symbol (movie clip) to the class. The instantiation is made when you place that symbol on the stage and hit that frame. From what I've read you can't pass parameters into this class. Any ideas on this?

Class

Actionscript Code:

public var _videoURL:String;// = "video/showreel.mov";
public var _imageURL:String;// = "image/showreel.jpg";

Timeline

Actionscript Code:

mcVideoplayer._videoURL = "video/showreel.mov";
mcVideoplayer._imageURL = "image/showreel.jpg";

mcVideoplayer._imageURL = "image/showreel.jpg";

No, this didn't do it. Comes up with error "1120: Access of undefined property mcVideoPlayer". Because I'm not creating an instance of mcVideoplayer (it's being created through a symbol that's linked to the class) I can't reference it.

I am 1000%+ SURE the process is CORRECT.

mcVideoplayer._videoURL = "video/showreel.mov";
mcVideoplayer._imageURL = "image/showreel.jpg";

This code will go on Timeline where the symbol is located. and mcVideoplayer should be the instance name of that symbol/MovieClip.

And you also have to declare that property in you Videoplayer Class, which is:

public var _videoURL:String;// = "video/showreel.mov";
public var _imageURL:String;// = "image/showreel.jpg";

Save the Class first, then test your Movie.

Wow, freaking awesome! Thanks arkitx... I've been going at this for nearly a week!! The problem was that the MovieClip didn't have an instance name, so it wasn't being referenced. So placing this MC on the stage is what is creating the instance of the class right?

Final question - if I wanted to include a back button on the video player that jumped to a different scene "MainMenu" how would I go about that? I could create the button as an additional component in the video player scene which would both call the 'video finished' function and then jump scene, but it would be nice to call the function from within the class. I could then pass a variable into the class such as what scene I want it to jump to. I've tried this...

Actionscript Code:

this.gotoAndPlay(0, "MainMenu");

...from within the class but it doesn't work. Any ideas on this?

Hope you will find most of your answers from this attachment.

Awesome, thanks! Great resource. One thing though - it's written in AS2 so the line

Code:

---

this._parent.gotoAndStop(targetFrame,"SceneEND");

---

doesn't work. I've used

Code:

---

MovieClip(this.parent).gotoAndPlay(0, "MainMenu");

---

which works perfectly.

Thanks very much for your help!

Sorry for AS2 example.

Here is the AS3 example.

I forgot that your code was written in AS3.

Thanks arkitx, working fine now. Do you know why the video would be starting to play prior to it showing on screen? You can hear it playing, but you can't see anything. Depending on the size of the video I'm loading it can be anywhere from 0.2 of a second to over a second.

Is this happened from the first FLV you navigate to Play?
