How to reverse a motion script

[dinkledorf]

As an example, in Swishmax, I

create text,
add a motion effect,
convert it to a sprite,
name the sprite "test"
open the sprite,
put a "forward" label at the
beginning of the timeline,
put a "reverse" label at the
end of the timeline,

at the scene level I insert
the following code:

onClipEvent (enterFrame) {
if (test.mode == "reverse") {
test.prevFrame();
} else {
test.nextFrame();
}
}

and the effect plays until the
label "reverse" is encountered
in the timeline at which point
the effect plays in reverse back
to the "forward" label in the
timeline.

I'd like to accomplish the exact
same thing in KoolMoves.

It may or may not require
actionscript to accomplish
the same thing in Kool Moves,
but, I've yet to be able to figure
it out.

For example, adding text and
applying the "Blinds" motion script.

Anyone?

First trick....forget all the ways you did things in Swish. Swish's motion scripts are frame dependent meaning the number of frames they span alters the outcome...slide in fast or slow for instance......in Koolmoves Motion Scripts are single frame wonders. To reverse those you use a combination of scripting (the motion script itself) and timeline navigation. That is why you will notice many have the option parameter of "Reverse". If you used a frame based effect (like the fade in/fade out/spin/rotate effects)....your old method is the same.

Thanx for the example, Chris.

I think maybe I need a tutorial not just an example.

Yours is a very simple example, that, I can't make
heads or tails out of. I mean I understand HOW it
works. I have no clue how to pick it apart and put
it back together or to recreate it from scratch.

Conceptually speaking it's like understanding how
an automobile engine works and getting from that
understanding to building one or taking it apart and
putting it back together again.

I'm just not figuring it out.

Here's some examples I put together using SwishMax
just to try to help me understand the process (and I
understood from your explanation that SwishMax and
KoolMoves are apples and oranges apart in their process)

At any rate, from your example both effects load and
a variable is set to "false". Then a button is clicked and
that variable is set to "true". And at that point the effects
reverse. Somehow, clicking the button triggers the reversal.

That much I think I understand. But, that's about it.

Here's my examples.

(I also did them because I wanted to compare final size.)

The Koolmoves example exported to (swf) 27k (from v5.5 - Demo).

The swishmax examples exported to (swf) 2-3k.

Reversed effect (Ping Pong):

Effect with push button for reverse:

Nothing beats rub my stomach, pat my head thought process for
a real doozy of a headache.

Working at forgetting how swishmax works in the process of figuring
out Kool-Moves.

Maybe if I just beat my head against a nearby wall a few times until
the feeling subsides...

I'm sure one will come along. I didn't realize you were on the demo. I'm going to clear the attachment to save space in my total. Good luck on the transition over if you decide to purchase

Unless the particular motion script has a reverse parameter you can't reverse the action unless you rewrite it yourself.

I wanted to add that my example used a button component for the example. In an empty movie with a flash 6 button component it would add 23k to the file size....if a flash 8 button component about 13k. Now you Swishers may find that unreasonable but you must remember that Swishmax has NO button components (buttons that accept scripted button commands with standard AS1) which I find equally unreasonable

At the time I made the example I was more concerned with showing that Koolmoves can do anything Swish can and did not realize it was also a size competition. Had I known I would have possibly chosen a different style of example. Being a previous Swisher myself (2+ years) I don't want any Swisher who may be coming over to our platform to think that they would be downgrading their toolbox but would actually be miles ahead of what they are using now (Koolmoves acts and scripts like big red) if they do. If a few "k" make the world of difference and is worth sacrificing power for sheer size...you should remain a Swisher. If power is your primary goal...then run...don't walk here....from Swish

Chris, when you got that 23k example, are you sure you unchecked the flash 6 components checkbox otherwise both are included. Normally the flash 8 components also take about 13k.

If it was a motion script effect, that also adds a few extra kb since KM effects are scripted and (most ?) Swish effects are precalculated if I'm correct.

[Chris_Seahorn]

I had it backwards...was just about to update the post.

F8=13k
F6=23k

Sorry

Had I not used the F6 button I did in the example it would have smoked his Swish example but like I mentioned he did not mention exported size was also being checked. I was a bit irritated so I removed the example and will let him decide what platform he prefers based on their own merits. If he converts...great...if not...oh well

Yes..Swish precalculates and divides over the span of frames. A shorter span speeds up a longer span slows down.
