Hi folks This is quite embarrassing as I remember knowing how to do this and used it many many many times in the past, but I have not used flash is so many years I have forgotten what I am meant to do.

Ok my issue is I have thee most simplest animation you could think of , a square, moves from one side of the screen to the other.

All i want is the box to slow down as it gets to end then begin to speed up again as it moves back.. same with the other side.

No matter what ease settings i put the box never eases right, or just dose weird things

my animation is like this
200 frames

Frame1 ----------------------------Frame100------------------------Frame200
(Box to left Keyframe)            (Box to center keyframe)            (Box to right)


What ease setting must i put?
I have been at this for an hour trying combinations of 100 ease in on frame 1, or ease out ,, or on frame 100 all of them only 2 arg i cant do it.. can someone pleases help

Frame200  - Ease OUT 100%



etc.. etc I have quite literally lost count with the amount of combinations I have tried.


All I want is the box to slow down (ease) as its gets to both sides to the screen

If i have not explained what i am trying to do can you see this video here:
https://www.youtube.com/watch?v=lZTaX4u-Z_k

Notice how the pendulum slows down as it gets to the right of the scree, then speeds up as it starts its return, gets to a max speed point around center, then starts to slow down on the other said, then speed up as it begins its return..

My test is not on a pendulum so there is no swinging motion. its just a box moving from one side of the screen to the other and back again in a looped animation.

dose anyone know the correct ease settings i must put for frames 1, 100 and 200?

all my test the box either dose it right on one side, but the other side it suddenly turns back its motion, other times it dose weird jittering in the center, other settings it just dose no easing at all.. i am absolutely pulling my hair out with this at the moment.

I need to get this figured out as its part of a project due by next weekend

Unfortunately I cannot offer anyone money who can explain this to me, however this is related to a game project and whoever can explain what I am doing wrong will get their name in the game credits for sure.

I haven't used flash in a while so it's going to depend on what they call ease in and what they call ease out (both can mean either thing depending on context :blind:)

But either way you're going to want

Frame 0-ease in (or maybe out but probably in)
Frame 100- nothing
Frame 200- ease out (or in if it's the other way around)

You may want to try numbers less than 100%. You also theoretically don't even need a centre frame.

Take a look at the motion graph to see what's going on when you change each of the properties.

Good luck, someone who actually uses flash might pop in to help but hopefully that pushes you in the right direction :y:

Yo Tycho!
I'm using Flash pretty much everyday.
@32 is right, the meaning of EaseIn EaseOut is often reversed by animators and softwares.
No one agrees.

It can either mean:
Ease In to final position = slow to a stop
or
Ease Out of motion = slow to a stop

So try reverse you're idea of what you think it means and that might help you be in tune with Flash's definition.
Also check the help file, it probs defines how Flash uses the terms.

This doesn't answer your question, but personally I don't use the EaseIn EaseOut sliders.
I prefer to control easing manually with keyframes.
Here's how:



But do what works for you man.
Good luck!
