how to control MC after attachMovie ? 1

[hovercraft]

onClipEvent(load)
{
	this._visible=false;
}


onClipEvent(enterFrame)
{
	if (Key.isDown(Key.CONTROL))
		{_root.attachMovie("mylaser", "mytest1", _root.getNextHighestDepth(), {_x:200, _y:200});
		
		}
}

After the instance of mylaser called mytest1 is created by pressing the control button, how and where would I put the code to animate the movie clip. I would like to simply reposition mytest1 so that it moves along it's y axis from the creation point (200,200) and move towards the top of the screen.

Thanks,
Dave

I don't know why you're using "onClipEvent", but anyway here's very basic example:

onClipEvent (enterFrame) {
	if (Key.isDown(Key.CONTROL) && laser == undefined) {
		laser = _root.attachMovie("mylaser", "mytest1", _root.getNextHighestDepth(), {_x:200, _y:200});
	}
	laser._y--;
}

Thanks Ken. I should have been a little more clear when I asked the question.

The onClipEvent is on a "control" object or in this practice example it's the ship its self.
The control object checks to see if a button is pressed to create the copy of the movie clip "mylaser".

Is it possible to program the onClipEvent of the instance "mylaser01" from within the "control" object (the object that gave the command to create the instance)?

Could this be accomplished with a "With" statement?

For example after the instance is created, have a statement in the onClipEvent (enterFrame) of the ship say:

with (_root.mylaser01) {onClipEvent (enterFrame){this._y = this._y -10;}}

The whole reason for this is because the object "mylaser01" doesn't reside on the stage (or even exsist) until it is created by the user pressing the CONTROL button. But without it being on the stage I can't program it's actions.

I'm probably over complicating this, but any help would be great.
Thanks again,
Dave

onClipEvent (enterFrame) {
	if (Key.isDown(Key.CONTROL) && !_root.mylaser01) {
		_root.attachMovie("mylaser", "mylaser01", _root.getNextHighestDepth(), {_x:200, _y:200});
		_root.mylaser01.onEnterFrame = function() {
			this._y -= 10;
		};
	}
}

(I would do it differently though.)

Wow, awesome! Thank you!

What sort of approach would you take?

 

[kennethkawamoto]

My approach would be to control everything from one place - either from main timeline and/or external Class files. Attaching scripts to MovieClips and Buttons with "onClipEvent()" and "on()" handlers is pre-Flash 5 methodology and has number of uncool issues.

You must avoid attaching ActionScript code to objects ... This practice is strongly discouraged ...
