How could I add dynamic FOV to my controller? I have a player setting that changes FOV at runtime and want to have the FOV increase a little when running. Is there a way to do this?
====EDIT====
This is the code I wrote. To change the FOV, you will need to do four things.
NOTE: Wherever you see YOUR_FOV_SETTING or YOUR_GAME_PAUSED, you will have to add your own values here. For YOUR_FOV_SETTING you will need to add whatever your setting variable is for FOV or a constant value if you don't allow the player to change the FOV in game. For YOUR_GAME_PAUSED, you can remove the if statement if you can't pause the game, and if you can pause the game just add in your way of checking to see if the game is paused.
You can also use this with any other controller or for whatever your needs are, not just this controller. Just remove the code for the Opsive Character Controller and make necessary changes and it should works.
VERSION 1.0.1
Added in crouching which lowers the FOV.

This is the code I wrote. To change the FOV, you will need to do four things.
- Add an enum value for the state you want.
- Create a state preset and set the PlayerMovementType enum to what you want.
- Add a property for your FOV.
- Add a case in the switch statement for the PlayerMovementType you added.
