Since 4.17 the Blueprint Compilation Manager broke the custom compiler by not using the interface meant for compilers even when they are available.
YOU HAVE TO DISABLE “Blueprint Compilation Manager” on 4.17 and 4.18.
A character that inherits from Paper2D and automatically manages the animation instance and notifies.
A fully functional blueprint class that allows the user to manage their own state machine, create transition rules and assign notifies to each state, will be compiled into a runtime class that can be used by the character (inherits from PaperZDAnimInstance)
The class that is constructed via the AnimBP and will be used by the character to drive the animation and notifies.
PaperZD also comes with special notifies, called PaperZDAnimNotify and PaperZDAnimNotifyState, they work just as their 3D counterpart and have the following properties
Allow the user to create “CustomNotifies” that are implemented by the PaperZDAnimBP, creating a special function that the user can complete. This way the user can avoid having to create a new Blueprint or NativeNotify for functionalities that will not be replicated on other blueprints.
-Can be derived via Blueprint.
-Can be derived natively, creating native notifies.
-Includes basic notifies (play sound, etc).
