Opportunity Attack Ability
The Opportunity Attack Ability manages Actor and Camera animations to perform an attack with a cinematic flair.
Contextual Animations
The Opportunity Attack uses a Contextual Animation Asset to manage the animations and motion warping between an attacker and a victim. The roles are not strict, but you need a primary and secondary role in your scene.
The primary role is always meant to be the victim, which is collected via the Target Preset assigned to the ability. The secondary role is always meant to be the attacker, which is the Ability Avatar.
Additional Roles
If you need additional roles in your scene, such as a third actor, or an environment "prop", then you can override the CollectAdditionalSceneActors function, from the Opportunity Attack Ability.
This function returns a map of Role Names and Actors that should be provided to the Scene Asset.
Camera Animations
You can optionally add a Camera Animation, usually created using the Level Sequencer, to add a cinematic flair to your opportunity attacks.
Camera Anchor
This actor provides the camera that will be used to play the animation. You can extend this actor to adjust how you want your camera to behave or even to use a different kind of camera, such as the Cine Camera.
For camera transitions, you don't need to extend the Camera Anchor. Instead, you can override the BuildCameraAnimationParameters function, from the Opportunity Attack Ability
