Fishing game code problem..

[baker]

Hi Guys,
Im building a fishing game for one of my uni modules. I got a tutorial off the net. THe proble mis, i have a masked layer with 2 sub layers, one called line, and one called hook.

The code works to extend the fishing line as the down and up keys are pressed, but i cant get the hook to move with it..

onClipEvent (enterFrame) {
if(Key.isDown(Key.DOWN)) {
this._yscale+=100;
_root.hook._y+=8.6;
} if (Key.isDown(Key.UP)) {
this._yscale-=100;
_root.hook._y-=8.6;
} if (this._y < 272) {
this._y = 272;
_root.hook._y = 282;
}

First- what does 8.6 mean in the _root.hook._y+= can someone just translate what this code means and perhaps i can get the hook to link with the line. At the moment only the line moves. Ive followed the tutorial but my axis positions are different....

you're adding 8.6 to hook's _y position every time a key is pressed
