Problems calling Public Functions

[tsquini]

I am having an issue calling public functions between classes.
I have 2 classes: FLVPlaybackCaptioningExample and DynamicButton.
In the DynamicButton class I am defining all of the mouseEvents on the dynamic buttons. On MouseEvent.CLICK I call a function from FLVPlaybackCaptioningExample that should .seekSeconds() to the FLV
player on frame 1 of the timeline.

To create the buttons I am loading a MovieClip from the Library
and using the class "videoCap.DynamicButton"

When I compile the movie it gives me an error:
1180: Call to a possibly undefined method seekToMovie.

package videoCap{
import fl.video.CaptionChangeEvent;
import fl.video.FLVPlayback;
import fl.video.FLVPlaybackCaptioning;
import flash.display.MovieClip;
import flash.text.TextField;
import flash.system.*;

public class FLVPlaybackCaptioningExample extends MovieClip {

private var videoPath:String = "TESTVid.flv";
private var captioningPath:String = "caption.xml";

public function FLVPlaybackCaptioningExample() {
player.source = videoPath;
captioning.flvPlayback = player;
captioning.source = captioningPath;
captioning.autoLayout = false;
captioning.addEventListener(CaptionChangeEvent.CAP TION_CHANGE, onCaptionChange);
writeNav();
}


//--------------------------//
I can't seem to call this function
public function seekToMovie(mySeekNum:Number):Number{
player.seekSeconds(mySeekNum);
}
//--------------------------//



private function onCaptionChange(e:CaptionChangeEvent):void {
var tf:* = e.target.captionTarget;
var player:FLVPlayback = e.target.flvPlayback;

// move the caption below the video
tf.y = 210;
}
public function writeNav(){
for (var i:int = 0; i < 1; i++) {
var newCircle:videoCap.DynamicButton = new videoCap.DynamicButton();
newCircle.name = "nav" + i;
newCircle.setLabel(newCircle.name);
newCircle.setInternalVar(i);
newCircle.y = 25 * i;
newCircle.myNum = i;
newCircle.x = 120;
addChild(newCircle);
}
}
}
}


package videoCap{
import flash.display.*;
import flash.text.*;
import flash.events.*;
import flash.display.MovieClip;
import flash.system.*;

public class DynamicButton extends MovieClip {
private var clicked:Boolean = false;

public function DynamicButton() {
this.buttonMode = true;
this.mouseChildren = false;
clicked = false;
this.addEventListener(MouseEvent.MOUSE_OVER, rollover);
this.addEventListener(MouseEvent.MOUSE_OUT, rollout);
this.addEventListener(MouseEvent.MOUSE_DOWN, mouseClickDown);
this.addEventListener(MouseEvent.MOUSE_UP, mouseClickUp);
this.addEventListener(MouseEvent.CLICK, mouseClick);
}

public function setLabel(thisLabel:String){
visibleLabel.text = thisLabel;
}
public function setInternalVar(thisNum:int){
myNum = thisNum;
}

public function rollover(event:MouseEvent) {
if (clicked) {
gotoAndStop("down");
} else {
gotoAndStop("over");
}

}

public function rollout(event:MouseEvent) {
gotoAndStop("normal");
}

public function mouseClickDown(event:MouseEvent) {
clicked = true;
gotoAndStop("down");
}

public function mouseClickUp(event:MouseEvent) {
clicked = false;
gotoAndStop("over");
}
public function mouseClick(event:MouseEvent) {
trace("HHHHH");
trace(myNum + " myNum");


//--------------------------//

seekToMovie();

}
}
}

seekToMovie doesn't exist inside of the DynamicButton class... you're basically saying

this.seekToMovie();

you need to say where seekToMovie is... and it is inside of the other class. So you'll need a reference to the instance of that class, and then call it.

if it's a basic static function (non dependent of a single instance) then make it a static funciton and you can call it by a theClass.theFunction(...);

this last example is very dependent though. In a static function you can not be defining anything inside of a class that is instance dependent. i.e. a static function inside of a class that extends a MovieClip can not tell that movie clip to change its x position. the x position is instance dependent. But it can tell a reference passed through the function to change its x position. Just not its own.

}
}

2 things that I see here.
One is that you are calling a method in a different class, so unless that method is static (which probably wouldn't be a good idea in this case) then you will need an instance to run it.
Second, doesn't it need at least on parameter? your call doesn't have any.

Thank you for your reply.

I made the function static and I was able to access the it but I could not control the FLV player. How would an Instance be structured to call this function?


/*FLVPlaybackCaptioningExample Class*/
public static function seekToMovie(mySeekNum:Number){
player.seekSeconds(mySeekNum);
}

/*DynamicButton Class*/
public function mouseClick(event:MouseEvent) {
/****************************/
FLVPlaybackCaptioningExample.seekToMovie(50);
/****************************/
}
