Ability

Dec 15, 2016

An Ability is a discreet action (or series of actions) that are initiated due to some set of rules (user input, scripting, etc).

Abilities themselves are made up of actions called Tasks that are executed along a timeline and according to the rules of the Ability itself.

Abilities come in two flavors:

Active

Passive

Both

    • The time, in seconds, that it takes for the Ability to complete.

  • Cooldown (Optional)

    • How long, in seconds, before the Character can re-activate this Ability.

Passive Properties

    • The total number of "Stacks" allowed for this Ability.

    • Can be controlled / queried from Blueprints to allow Designers full control.

  • Refresh Duration On New Stack (optional)

    • If true, the Ability duration will be reset back to 0 every time a Stack is successfully applied.

  • Always Refresh Duration (optional)

    • if true, the Ability duration will always be reset to 0 every time a Stack is attempted to be added (whether successful, e.g. due to max stack limit, or not).

  • Only Refresh Loop Time (optional)

    • if true, instead of resetting the Ability duration to 0, it'll reset the duration to the Loop Start time.
