Velocity, or acceleration can be added to an objects motion along a path.
In this demo, an object will ease out (accelerate) then ease in (decelerate).
We start by setting the number of animation frames in the Action Script.
In the Stage Editor, a default, OPEN PATH is added & saved to disk.
`SHOW PATH LENGTH is used to get the size of the path in pik cel units.
SHOW PATH LENGTH is used to get the size of the path in pixel units.
`This information will be used to cal q late the necessary velocity values.
This information will be used to calculate the necessary velocity values.
`To make things simple, this value will be rounded off to an even 1 hun dred.
To make things simple, this value will be rounded off to an even (100).
This value is used to find out what the Object's normal speed would be.
`For example, with this twenty frame animation & 1 hun dred unit long path,
For example, with this 20 frame animation & 100 unit long path,
`The objects normalspeed is 1hun dred divided by twenty,or,ten units perframe.
The object's normal speed is 100 divided by 20, or, 10 units per frame.
In the Action Script, we can now add the object that will follow the path.
A new Position time-line will replace the default. It is set to FOLLOW PATH.
These fields let you enter values to affect velocity:
ACCELERATION FRAMES sets the beginning frames where acceleration will occur.
STARTING SPEED sets the speed at the path's start. 0 means stopped, no speed.
DECELERATION FRAMES sets the ending frames where deceleration will occur.
ENDING SPEED sets the objects speed at the end of the path. 0 means stopped.
With the values entered, our object will accelerate from a stopped position,
`for 5 frames, up to its normal speed of ten units per frame,
for 5 frames, up to its normal speed of 10 units per frame,
`It maintains this speed for ten frames, 
It maintains this speed for 10 frames, 
then decelerates, over the last 5 frames to a complete stop.
`MAKE will be used to build the animation pre view.
MAKE will be used to build the animation preview.
PAUSED: Press Space after the animation has completed.
