Abstraction of Brush "Moving Behavior"

[ulikk]

My idea for handling moving behavior is as follows:

• "Moving Behavior" is abstracted as the behavior for updating the brush's position over a period of time.
• The current Moving Behavior consists of a brush moving randomly along a randomly changing direction.
• Each Moving Behavior has an internal state and configuration variables that should be manipulatable via the GUI.
• A global Movement property is "respawn frequency min/max"

Examples:

• Random (the current Behavior, parameters: movement change frequency min/max )
• HalfCircle (parameters: half circle radius min/max )
• Spiral (parameters: spiral radius min/max, spiral windings min/max)

I can imagine a GUI with a "movement parameter" area, that changes accordingly when a new Movement is selected. I see two options for implementing this: either all GUI elements are defined in the html and only one is made visible at one point in time, or the GUI elements are instanced at runtime, according to the selected behavior. I guess the second variant is more difficult to implement. I'm not sure if it can easily be done with angular as well.
