OnClipEvent, Speed, Offset

Question 1
i guess the bottom line is why bother using clip events?
A: when i talked to Tage about it the answer was first of all notice that
the action was written on the button for the onClipEvent. So I then asked well why not just use onPress.....apparently onClipEvent is for non user initiated actions.
which renders onClipEvent useless b/c the currrent thinking is to not put actions on MC as much as possible. Thus its better to just use functions written on the timeline.


Question 2
speed and offset are they recognized flash words?
Offset is : (though it doesnt turn blue)
offset (Point.offset method)

public offset(dx:Number, dy:Number) : Void

Offsets the Point object by the specified amount. The value of dx is added to the original value of x to create the new x value. The value of dy is added to the original value of y to create the new y value.

Availability: ActionScript 1.0; Flash Player 8

Parameters

dx:Number - The amount by which to offset the horizontal coordinate, x.

dy:Number - The amount by which to offset the vertical coordinate, y.

Example

The following example offsets a point's position by specified x and y amounts.

import flash.geom.Point;
var myPoint:Point = new Point(1, 2);
trace(myPoint.toString()); // (x=1, y=2)
myPoint.offset(4, 8);
trace(myPoint.toString()); // (x=5, y=10)



Speed isnt recognized by flash its just a made up word. When I said to Tage
it doesnt seem logically that when i wanna move something that its connected to speed. I think of _x and ++ to move things but he said what if u wanted it to move faster tahn u have to think of speed.

But he said he also didnt get it why MR would do it this way;
this.ball_mc.speed = 6;

Tage says he does it this way var Speed:Number =6
-------------------------------------------------------------------------------------------
they both inititialize


onClipEvent (load) {
// init something here
this.speed = 4
}


this.ball_mc.speed = 6;
this.ball_mc.offset = (this.ball_mc._width * .5)


Both using on EnterFrame
Both using If statements
Both mc's

onClipEvent (load) {

this.speed = 4

onClipEvent (enterFrame) {
// make it loop here
this._x += speed;

this._parent.????

//when user presses button
on (rollOver) {
this.gotoAndStop(2);

//when user rollout button
on (rollOut) {
this.gotoAndStop(1);

//when release
on (release) {

leg rotation

this works:

leg_mc.onMouseDown = function () {
this._rotation += 5
}

but this doesnt

leg_mc.on(press)= function () {
this._rotation += 5
}

this is how it was originally written
this.onMouseDown = function () {
this.leg_mc._rotation += 5
}

onClipEvent (load) : why?

My question why is do u need onClipEvent (load) in this, u can easily put it in the other statement


onClipEvent (load) {
trace("Hello World");
this._alpha = 50;
//this._visible = false
}


onClipEvent (mouseDown) {
this._rotation = this._rotation + 5
}
