The Ranvier engine itself doesn't prescribe or prefer any certain type of combat, it simply has tools in place to allow you to implement which ever type of combat you prefer. This bundle is an example implementation of Diku-style autoattack combat. While it is an example implementation it is stable enough to be used in your game should you choose not to replace it.
This bundle works by listening on the updateTick event for players and NPCs and then using a
custom Combat class (lib/Combat.js) to handle round timing, finding a target, doing damage, and
death. The player-events.js file binds to the events that Damage and Heal emit as well as
some custom events that the Combat class emits (deathblow, and killed).
NOTE: When using this bundle NPCs will not fight back if they are not given the combat behavior.
They will simply sit there as the player kills them.
