Description of feature request

Instead of an AI doing it, make it so that a player can control it. If it is already implemented, please write how to do it.

If the player is in a multiplayer world, there should be arrows pointing to the other players.

Given how complex the Wither Storm is and how heavily code driven it is I don't think this is going to be something we do, but if Crackers wants to reopen this in the future I'm sure he will

Sad but understandable.

You can use commands to redirect where it's going: https://github.com/nonamecrackers2/crackers-wither-storm-mod/wiki/Commands-and-Technical

Was not expecting a reply. To be more precise, is there a way for to make the wither storm target only mobs (does not matter which ones) while ignoring players?

No that is currently not possible, I'd make a new suggestion if you're wanting to have that in the mod
