Joysticks in Synfig (Controller Plugin)

Slider demo with Controller Plugin
Sliders are useful to interpolate between poses or 2 values.

Here’s the plugin (please use it and report any problem, this will help improve the plugin faster and have fewer issues)

sliderPlugin.zip (5.5 KB)

To create a slider:

1. Create keyframes.

2. Add waypoints on the keyframes.
   a. If a parameter has waypoints on all the keyframes then it will be connected to the slider.
   b. Extra waypoints (in between keyframes) are ignored and if a parameter doesn’t have waypoints on all keyframes that parameter is ignored.(This might change in future)

3. Considering each keyframe as a pose, sliders are created based on the number of keyframes. (If you have 5 keyframes 4 sliders would be created, the first is considered as initial pose)

4. Slider’s have the name sliderController{numb}_keyframeNum where numb is a random number in 1000-9999 and keyframeNum is the frame at which the keyframe was located.(Keyframes aren’t deleted)

(Works with vector, real, angle, color I haven't implemented rest (same goes for joystick controller), I don't think they are important. If required we can implement that later )

ToDo:

1. Create switch template (to switch images or shapes in switch layer with controller)
2. Create slider
3. Create multiple controller/slider without requirement to re-run the plugin again and again
4. Feature to Unbind the controller and get the waypoints again (so that mistakes can be fixed)
5. Bind multiple layer or group to existing/new controller (by providing a ID for controller)
6. Controller for exported values

I will merge them and move to the next steps.
When merged you can create joystick, switchTemplate, slider by giving prefix to the group layer (for example, joystick_myjoystickController, switchTemplate_demoName, slider_colorSlider, etc)

Hopefully, the next remaining steps would be easy and I would complete them soon.
