it comes to animation, nothing beats Flash. Flash has an arsenal of
powerful tools that help to make animations easily. If you have done
some animation in flash then you know that frame by frame animation gets
a little hectic sometimes. There is tweening ; but it is only
helpful when the change in position of a body is in the same direction.
If you want your object to follow a specific path which is not in one
direction then that's where guide layers come in. Guide layers are
exactly what their name suggests, they guide the object to maintain
their path of motion. In this tutorial I am going to show you how to use
guide layers. You have to know the basics of animation in Flash before
you can take this tutorial, If you want to start on that then please see
my previous tutorial about animation.
by creating a new document in flash. First of all we will make the
object which we need to move. I am making a simple circle. The object
needs to be a movieClip otherwise it would not work with the guide
make a new layer and draw a line on it, this line is the path that the
ball will follow. I have drawn a wavy line with a green color. The color
is not important here because it would not be visible in the output.
right click on the layer with the path and select the guide option from
the context menu. This will transform the layer into a guide layer.
You will know that it has successfully transformed when you see the icon of the layer change.
the ball is not bound to the guide yet, to do that drag the ball layer
with your mouse and move place it on the lower side of the guide layer.
When the ball layer becomes a part of the guide you will see it like the
make the ball move with the line, the ball needs to be on the line
first, drag the ball on the line such the circle showing the center of
the ball is on the line.
press F6 on any other frame in the ball layer to insert a new frame
there. Press F5 on the same frame in the guide layer to extend the
guide layer upto that frame. Now in this frame change the position of
the ball but you have to make sure that the center of the ball is still
touching the line.
last right click on the middle of ball layer and choose classic tween
to tween the ball. Press Ctrl+ENTER to test the movie and you will see
the ball move along the line of the guide layer.
can use this method to dramatically decrease the time of making an
animation. I hope this helps you become a better animator.
