2.0 Add Character Animation support

[Jowan-Spooner]

Animations for portraits

Animations are a script file that extends the new DialogicAnimation class.
There are currently X animations:

• fade_in_up
• fade_out_down
• bounce_in
• bounce_out
• instant_in_out
• tada
• heartbeat

These scripts have to have an animate() function. The class has a couple of variables that you can use, most importantly the .node which is a reference to the node that should be animated.

The animations should emit finished_once once finished. The animations above use the SceneTreeTweener for animating (except for the instant animation).

Animations on character event

The Character event has a couple of more settings, that show under different circumstances:

• AnimationName (the path to the animation)
• AnimationLength
• AnimationRepeats
• AnimationWait

In the text version they are stored as an additional shortcode.
E.g.: Join Emilio (sad) 3 [animation="Bounce In" length="2.0" wait="True"]

Animation settings

There is a settings page for animations where you can specify a custom animations folder as well as default settings for join and leave mode.
They default to:

• Custom Animations: 'res://addons/dialogic_additions/Animations'
• Join Animation: ['Fade In Up', length = 0.5, wait = true]
• Leave Animation: ['Fade Out Down', length = 0.5, wait = true]

Additional changes

Resource picker

I've decided to make the resource picker more adaptable (to use it for the animations).
You can now specify a method for listing suggestions. If you give a file_extension it will default to listing all of those files.
