Question

Line Graph Animation

Asked by: rruth

Here is the situation: I need to have a curser move horizantally, right or left along a curved graph line and is controled by either a right or left arrow mc. When the user stops the cursor and clicks either an up or down arrow mc, it will move that point on the graph line up or down, bending the graph line in the direction the cursor moves the point on the graph. I have created 4 movie clips working as buttons to control the four directions of movement by the cursor. I am not sure how to attach the cursor to the graph line or how to make the graph line bend up or down depending on the cursor moving up or down. I have some experience with AS 2.0 but this is beyond me. Any help would be very appreciated

when you refer to cursor are you refering to the mouse cursor? or some fake object you'r creating?
 if the former, i dont think that can be done. at least i've never seen someone control the mouse with the keyboard.
if the latter you're wanting to use the drawing API to draw lines dynamically.
you'll need to use event listeners to follow the position of your objects and draw the lines there.
more info required - assuming AS2.

The cursor is a 2 by 4 pixel rectangle mc that is attached to a graph line and needs to move right or left on the graph line depending on whether a right or left mc button is clicked on. At any point on the graph line, if an up or down mc button is clicked on, that point on the line needs to move up or down bending the graph line in the direction the cursor is moved. I am really sorry if this is unclear. I wish I knew how to explain it better. I am trying to do this in AS2. Thank you for any help you can give.

ok.if no one else comes to assist, have a look at how to draw lines etc in flash.

//straight line
this.createEmptyMovieClip("line_mc", 10);
line_mc.lineStyle(1, 0x000000, 100);
line_mc.moveTo(0, 0);
line_mc.lineTo(200, 100);
line_mc._x = 100;
line_mc._y = 100;

//curves
this.createEmptyMovieClip("circle_mc", 1);
with (circle_mc) {
    lineStyle(4, 0x000000, 100);
    beginFill(0xFF0000);
    moveTo(200, 300);
    curveTo(300, 300, 300, 200);
    curveTo(300, 100, 200, 100);
    curveTo(100, 100, 100, 200);
    curveTo(100, 300, 200, 300);
    endFill();
}

thinking you're not going to attach the cursor to the line but rather draw the line where the cursor is.
i have some work i need to finish if i get a chance i'll see if i can do a mock up.

That's pretty cool, I will be able to use that in other applications. I guess I will make this a two part question. For the first part, the cursor will be attached to the line and move right or left along that line depending on whether the user continuously keeps a right or left mc button pushed down. I have worked out the code to listen for a mouse down event and enterframe so it will loop as long as the mouse is down. How do I keep the cursor attached to the line?

I will post the second part as another 500 pt question based off of the results of the first. I hope that you stick with me on this. - Thank you so much for your help!

have a look at the code snippet from the help file. (use your help file, it really does help)

the line of code that is of interest to you.

this.startDrag(false, this.left, this.top, this.right, this.bottom);
that's how you drag something around, and it can constrain it to another item, in this case the slider knob to the line.

var my_sound:Sound = new Sound();
my_sound.loadSound("song3.mp3", true);
 
this.createEmptyMovieClip("knob_mc", this.getNextHighestDepth());
 
knob_mc.left = knob_mc._x;
knob_mc.right = knob_mc.left+100;
knob_mc.top = knob_mc._y;
knob_mc.bottom = knob_mc._y;
 
knob_mc._x = my_sound.getVolume();
 
with (knob_mc) {
    lineStyle(0, 0x000000);
    beginFill(0xCCCCCC);
    moveTo(0, 0);
    lineTo(4, 0);
    lineTo(4, 18);
    lineTo(0, 18);
    lineTo(0, 0);
    endFill();
}
 
knob_mc.createTextField("volume_txt", knob_mc.getNextHighestDepth(), knob_mc._width+4, 0, 30, 22);
knob_mc.volume_txt.text = my_sound.getVolume();
 
knob_mc.onPress = function() {
    this.startDrag(false, this.left, this.top, this.right, this.bottom);
    this.isDragging = true;
};
knob_mc.onMouseMove = function() {
    if (this.isDragging) {
    this.volume_txt.text = this._x;
    }
}
knob_mc.onRelease = function() {
    this.stopDrag();
    this.isDragging = false;
    my_sound.setVolume(this._x);
    
};

I am off for a few days but will go through the code when I am back this weekend. I really appreciate your help and patience!

Unfortunately I have not had a chance to work further with this issue. This is something that I will have to tackle and will probably re-introduce it when I can give it my full attention. I have given you the points because you stuck with it.
