The document introduces the Deco Tool in Adobe CS5 which can be used to add drawing effects. It also discusses how Flash can use inverse kinematics to create marionette-style movement by using the Bone Tool to create joints that can be manipulated to form links and create an armature layer. The document provides an example of using inverse kinematics to make a snake symbol slither around the screen by connecting circles with bones.

1. PAL #4: Deco Tool & Inverse Kinematics

2.  Newly introduced in Adobe CS5 is the Deco
Tool (Keyboard shortcut ‘U’)
 It can be used to add quick drawing effects to
your multimedia productions.

4.  Flash can use a process called
inverse kinematics to create a
‘marionette’ style of
movement.
 Using the ‘Bone’ Tool you can
create joints that can be
manipulated.
 Use the tool to draw multiple
‘links’ as necessary.

5.  Flash will automatically
create an ‘Armature’ layer
for you.
 Right click on a timeline
frame and select the
option ‘Insert Pose’ to
alter the positioning of
your bone structure.

6.  Create a simple ‘snake’ from filled circles
converted into symbols.
 Use Inverse Kinematics to make the snake
slither around the screen.
