Animation Controllers

Everything you animate in Awakening is handled by a controller. Controllers handles the storage and interpolation of all animated values. Once you click the "Set Key" button in the Animation Panel to create a key, Awakening will assign controllers for every animation parameter. These controllers are listed in the Controller Box. Different data type parameter has different controller type. Below is a table of controllers in Awakening:

 

Data Type

Interpolation Class

Sample Use

Simple Controller

Float

Step, Linear, Spline, Spline (continuous ), Wave, Noise, Perlin Noise Width, Height

Complex Controller

Bool

Step Switch

ARGB

Linear Color

Vector3

Linear, Spline, Spline (continuous ) Position, Orientation, Scale

Complex Controllers have Sub-Controllers, you can change Sub-Controllers respectively. For example, you can assign a "Wave" float controller to "A(transparence)" element of color to produce swing between appear and disappear.

Interpolation Class Illustration:

Step
Linear
Spline
Spline (continuous)
Waveform
Noise
Perlin Noise

Horizontal axis is time, and vertical axis is value.

 

Amplifiers of Controller

Amplifier is a mechanism for amplifying controller input/output data. Every controller have two amplifiers: Time Amp and Value Amp. To understand amplifiers, let us first realize how controllers work in animation. A segment of animation consists of multiple frames, every frames have a time - called frame time. When the animation system renders a certain frame, it passes the frame time to the controller for every animated parameter, then the controller returns animation parameter values; so the animation system uses the input value to change object states, like position, color, etc. See illustration:


A amplifier include three variables: PreOffset, Zoom, PostOffset. The amplifying formula is: Output = ( Input + PreOffset ) X Zoom + PostOffset .
