CookieCutter is used to create advanced operators very quickly!
|
|
|
|
To use:
|
|
|
|
- specify CookieCutter as a subclass
|
|
- provide appropriate values for Blender class attributes: bl_idname, bl_label, etc.
|
|
- provide appropriate dictionary that maps user action labels to keyboard and mouse actions
|
|
- override the start function
|
|
- register finite state machine state callbacks with the FSM.on_state(state) function decorator
|
|
- state can be any string that is a state in your FSM
|
|
- Must provide at least a 'main' state
|
|
- return values of each on_state decorated function tell FSM which state to switch into
|
|
- None, '', or no return: stay in same state
|
|
- register drawing callbacks with the CookieCutter.Draw(mode) function decorator
|
|
- mode: 'pre3d', 'post3d', 'post2d'
