Area effect weapons attacks

[Itxi]

Firstly, hello everyone :) This is my first post in a while.

 

I've recently started modding Skyrim and I'm struggling to get it to do what I want.

 

Essentially for my first mod I want to create a warhammer that allows you to strike the ground with a power attack and knock everyone around you backwards.

 

I have a magic effect that checks if the player is power-attacking and has more than 0 stamina, it then mimics the unrelenting force shout within an area of 20 of the player.

 

It mostly works as I want it to, however I can only apply the effect to weapons if it's activated through contact, which means that in order to take effect a character has to be targeted. Ideally I'd like it so I could use the ability anywhere to strike down multiple people pursuing me or just knock items around :P

 

Oh and it also doesn't affect items :/

 

Does anyone know of a way that I can get this to:

1. Not require striking an actor
   
2. Affect items
   

 

Thanks for reading :)
