This plugin adds a range of useful new state tree utility tasks and property functions.
Trigger a GameplayEvent on target actor(s), via AbilitySystemComponent. Fire on a single actor, or an array of actors, both of which can be bound to data.
Can fire different (or no) events on Enter and Exit state.
Any GameplayEvents received on the target actor, matching the specified tag, will be re-emitted as StateTree events. Allows using normal state tree transitions to respond to Gameplay Events e.g. on Actor.Died event transition to Dead state.
Useful as a global task, bound to the tree owner. Combined with "Trigger GameplayEvent" this allows bidirectional communication between the state tree and actors.
Options for bOnlyTriggerOnce and bOnlyMatchExact, like the WaitGameplayEvent Blueprint node.
Change input config (e.g. Game Only, Game & UI, UI Only) & associated options (e.g. mouse capture, cursor, input flush) on target player controller. Reverts on exit. Changes are debounced and applied on next tick to prevent flickering. Uses a stack of configs, so when you exit a state, the next config in the stack will be used. You may want to put a default config in your root state to prevent flickering.
Activates/deactivates a target UCommonActivatableWidget. Optionally performs the inverse on exit.
Sets the visibility of the target component to the target value. Unsets the visibility on exit.
Same as "Set Component Visibility" but calls the appropriate SetHiddenInGame on the target component.
Log a message to the output console and/or screen on enter/exit state. Same general options as regular Print Text Blueprint Node.
Useful for binding text properties to string data.
Useful for logging.

The plugin was developed for Unreal Engine 5.5.1+. It is unlikely to work in versions of Unreal Engine <5.5.0 due to heavy changes in the StateTree plugin. Please let me know if you get it working outside 5.5.1+.
