Limited Spectator Mode
is a datapack for Minecraft 1.14+ that enables all players to enter Spectator Mode whenever they want, with a few restrictions.

Restrictions:

1) The player can not travel more than 64 blocks away from where they enabled the spectator mode. If they try to fly further, they will be teleported back to their point of origin.

2) Upon leaving spectator mode, they will be teleported to the point they started, to prevent using the mode as a means of transportation.

How it works:

- Upon joining the server, every player is given a unique ID, stored in the scoreboard value sp_id.

- When they use the command "/trigger sp_on" they will go in to spectator mode, and an armorstand will be summoned at their location, with the same ID as the player.
(The location is shown by a floating golden helmet for players that are not in spectator mode)

- The armorstand will constantly check if the player is within a 64 block radius, and teleport them back if they go to far.

- To leave spectator mode, they player will have to use "/trigger sp_off" this will teleport the player back to the armorstand, and disable spectator mode.

Known "bugs":

1) Unloaded Chunks. (FIXED in latest version)
- If a player teleports away from their armorstand while in spectator mode, and the chunks they were in gets unloaded before the player gets properly teleported, they can move freely in spectator mode. This is only until the chunk with their armorstand gets loaded again. This is unfixable until mojang implements a stable way of keeping a chunk loaded. (the /forceload command can not be used by a datapack, sadly...)

I have implemented a function so that they can not use /trigger sp_off until the chunk with their armorstand is loaded, to prevent using the spectator mode as a mode of teleportation.

Status: Unfixable.

2) Bad admin...

- If an administrator uses /kill @e to kill the armorstand, spectators are stuck in spectator limbo, until an administrator saves them. This is done by using the following commands:

- /scoreboard players <playername> set sp_status 0
- /gamemode <playername> survival.

This should allow them to use the command again freely.

Status: User error...
