Is there a way to change the field of view using a command in Minecraft, without changing the walk speed? I'm talking about the option that, at its max, is labeled "Quake Pro".
I'm working on a top-down adventure map where the player is placed above a world (20 blocks or so) with FOV=30. When you get into a fight every 10 block walks or so it'll teleport you into a battle field where ideally your FOV would be around 70 (normal).
I tried increasing the speed effect of the player inside of fights but it's uncomfortable to fight when you're walking much quicker than normal.
I could slow down the walking speed of the player outside of battles, but then you get the same problem - you end up walking too slowly on the world map, and that's no good either.
EDIT: PS The method should work in 1.10.
