Playbacks
Playbacks decide how an effect gets applied through time (for example, playing an effect only once).
Built In Playbacks
You can use the following built-in playbacks to modify your effects, either assigning them from the inspector or setting them as modifier keywords:
For example, if you already have a "wave" effect that loops infinitely, but in one occasion you want to show it only once, you can write "<wave once>", where "once" is the ID of the playback.
Create Custom Playbacks
There are currently three different types of playback classes that you can instantiate:

Each playback has different parameters that you can modify (e.g. duration).
If any parameter is less or equal to 0, then it will be ignored and the animation engine will jump to the "next" important/related one.
Appearances and disapperances need at least one value to be greater than 0, or their duration will be invalid and they will be skipped
Simple
Delay before start
How much time the animation engine waits before starting to show the effect
Fade duration
How much time it takes for an effect to go from 0 to 1
Still duration
How much time an effect is displayed on screen.
Weighted
Intensity01
Lets you control externally how much intense should an effect be (e.g. 1 when near a game objective, 0 when too far)
Cycle
Delay before start
How much time the animation engine waits before starting to show the effect
Fade in duration
How much time it takes for an effect to go from 0 to 1
Still duration
How much time an effect is displayed on screen.
Fade out duration
How much time it takes for an effect to go from 1 to 0
Cycles
How many times this loop is repeated
Delay Between Cycles
How much time to wait before starting a new cycle
Playbacks Databases
As always, you can store playbacks inside a database and assign it to the Global Settings (p.s. there is already one built-in and already set up), like the following:

This way you can access all playbacks from all different Text Animator components, and modify your effects individually through Modifiers (example "<wave once>".
