-You basically have to make your own findref function with SKSE, if you want to avoid certain references, but especially the player because it's so easy for it to be the return value. First of all you need to pass this keyword into the function:

-This will return the closest actor. It's not efficient, and on the slow side but it's the best I could come up with. --[[User:Rasikko|Rasikko]] ([[User talk:Rasikko|talk]]) 2017-12-15T14:47:39 (EST)
+This will return the closest actor. How fast this function returns, depends on how many actors are in the cell. --[[User:Rasikko|Rasikko]] ([[User talk:Rasikko|talk]]) 2017-12-15T14:47:39 (EST)
