Subject: [IML] QUEST: Follow path info
How do you get an object that is following a path to ease out slowly and
smoothly. I cannot seem to be able to figure it out. None of the manuals
tell you. I have a letter following a curved path with two knots, (first,
last). I want the letter to gently come into its final resting place, (last
knot). I have tried many, many different combinations of numbers but to no
avail. the effect is so weak that it makes little difference. I get the
path length in the stage editor, divide that by the number of frames to get
the units/frame. I then use 1 as the De/Ac frame, 2, 3, 4, .. times the
unites/frame as the start unites/frame, 20 as the De/Ac end frame count,
and 0 as the end units per frame. The results are puney at best and not
really useful. Any Ideas???
Thanks in advance.

Assuming you have gone to the action dialog and deleted the POSN bar. Then
adding it you have an option for TWEEN or Follow Path. Once you select
follow path, you have acceleration and deceleration options.

Yes that is what I have done. It is that, "Follow path info" that I cannot
seem to figure out. I thought it is for creating ease in/out function. Thanks

Then try the Velocity scaling on the objects options under the action
dialog. I know one of them does what you want.

Velocity has no effect on objects following a path. It does however have
definate effect on object movement that is not following a path.

What you might want to do then is to break the action bar into two bars.
Have the first one take x amount of frames to get where you want and then
have the second speed it up to finish off the frames.

Clifton,
Here are the settings I used in a test:
(De)Acceleration Frames 0
Starting Speed 0
(Ac)Deceleration frames 30
Ending Speed 0
The test featured a 30-frame "Follow Path" Action Dialog bar. The
numbers I entered specify maximum deceleration (100% of the path travel
time), for the smoothest deceleration possible. In this case, the object
will come to a stop over 30 frames, or one second, When played back, the
test anim still doesn't look that great; that's not Imagine's fault,
it's simply that a one-second deceleration really can't look smooth to
the eye. Look at it this way: if you were in a car and your speed
dropped to zero in one second flat, I'll bet you wouldn't find the ride
smooth!
