USING MOTION GUIDES IN FLASH CS3
- THE ANTS NEST TUTORIAL
A motion guide is a line you have drawn with the pencil tool on a guide layer.
You can attach your object or character to the line to make it follow that path.
This can save time, particularly when doing an animation sequence that involves
substantial movement.
In this tutorial, you will learn how to create a motion guide by designing your own
ant’s nest. You will create the different tunnels and then make a guide to show
your ant where to move within the nest.
1. Start by selecting a light brown colour for the background in the properties
section.
2. Rename Layer 1 with the name Background by double-clicking on the text
Layer 1 and typing in Background.
3. Using your rectangle tool, draw a large dark brown rectangle over the whole
stage area. To make the tunnels in your nest, set your eraser to the largest
size in the tool modifiers and rub out parts of the rectangle. This will create a
tunnel-like look similar to the image below.

4. Make a new layer on the timeline using the add layer button ( )
or by selecting Insert > Timeline > Layer.
Name the new layer ant.
5. On the ant layer draw an ant. You can do this
simply by drawing three overlapping circles and
adding small lines to make antennae and legs.
6. Select the ant and make it into a symbol in the
library by choosing Modify> Convert to Symbol.
7. Name the symbol ant and select the graphic option from the type
options. Select the centre square in the Registration option.
8. Your ant is now ready to be given a guide. To create a guide layer, select
the ant layer on your timeline and then click on the following symbol to add
the guide layer.
9. Your timeline should look like this.
Note: Your guide will only work if
the guide layer is directly above the
layer containing the object using
the guide. For example, if you
dragged the ant layer below the
background layer, the guide
would not work.

10. Click on the first keyframe of the Guide: ant layer and ensure it is
highlighted as in the above picture.
Using the pencil tool, draw the path you would like your ant to follow
through the ant nest. An example is showed below.
10. It is now time to snap the ant to the guide. To do this, we need to follow
these steps:
a) Ensure that the magnet icon in the tools options is
pressed on.
b) Select the ant on frame 1 of the ant layer. Position
your mouse on the centre of the ant where you will
see a crosshair. Move the ant using the crosshair
to the starting point of the guide.
c) You will be able to tell your object has ‘snapped’ to the guide, because
you will see an outline of a circle just behind the crosshair when
you attach it to the guide.
d) You have just positioned the ant at the start
of the guide. It is now time to position the
ant at the end of the guide. To do this you
will need to Insert a Keyframe further
down the timeline.
I will position mine at frame 50 by clicking on this frame and selecting
Insert > Timeline > Keyframe (or F6).To be able to see the
background and guide at frame 50, I will need to add a keyframe at frame
50 to their layers too. At this point your timeline should look like this.

The black line is the
guide for the ant to
follow. This line is
sometimes referred to
as the motion path.

e) Click on frame 50 of the ant layer and drag the ant to the end of the
guide. Ensure the ant snaps to the guide by watching for the blue
circle.
f) You have now positioned the ant at the start and end of the guide.
To make him move along the line, we will need to add a motion
tween.
To do this we need to click
between the two keyframes on
the ant layer and select motion
from the tween dropdown menu.
Congratulations, your ant should now move along the pencil guide you
have drawn on the guide layer. If it is not doing this, delete the guide
layer and begin the process again.
