Hey
The medieval combat starter kit includes melee tracing without the use of the plugin, since its integrated in the project itself. In therms of differences they use the same tracing method. except that the medieval kit also has tracing against the world objects ( im adding this to the plugin very soon though ). and Blocking using your weapon or a shield Besides that the medieval kit is a much more robust package for melee combat ( has animations, example meshes, etc ) While the plugin is more for those interesed only in the tracing / hit detection
