Operation Manual

Creating Animations 231
Once keyframes are created, the animator has a great deal of control over how
objects are run forward (or even backwards). You can introduce objects
anywhere on the storyboard (so they appear for a limited time), and either run
them forward or backwards by a specific number of keyframes (or right to the
start or end of the storyboard). The "Buzzzz" text in the above example will only
show from keyframes 3 onwards (i.e., from 4 seconds).
Supporting tabs
Keyframe animation mode also presents other tabs that support the Storyboard
tab. These are exclusively used within keyframe animation (and do not show in
normal or stopframe animation mode), i.e.
• The Easing tab is used for applying linear or non-linear changes
between key objects with use of editable envelopes (e.g., to change
object position, morph, scale, rotation, skew, colour, and
transparency).
• The Actions tab allows objects and keyframes to be attributed actions
which will run (e.g., go to a URL or designated marker) when an event
is triggered (e.g., MouseOver, Rollovers, etc.).
Advanced keyframe animation
DrawPlus provides a range of features for the more experienced user, i.e.
• Apply actions in response to object events or at a specific keyframe
either via an easy-to-use dialog or develop ActionScript™ code directly.
Actions are great when developing interactive applications or games.
• Use the Keyframe camera for panning, zooming and rotation effects
over keyframes.
• Masking lets you produce cutaways, i.e. punching through a layer(s) to
reveal underlying objects.
• Add and manage sound and movies to enhance your animation.
Manage files from one central location with the Media tab, which also
allows viewing and direct replacement of media.
