One Way Glider

Description

With this mod/datapack you can place a marker at the middle of your spawn island and every player in the defined radius of the spawn island will receive a one way glider.
Players with no chestplate equipped receive an equipped barrier block that serves as a glider (not an elytra so that they don't get the advancement).
When a player has a chestplate equipped (or the player equips a chestplate in the spawn radius), the chestplate will become an unbreakable glider to.
When a player has an elytra equipped, nothing happens.

As soon as the player touches the ground while not being in the spawn radius, the one way glider or the unbreakable glider attributes get removed.

Setup and config

Open config menu

You can open the config menu in 2 different ways. Either you open it through the pause screen (button marked in red):

or if this doesn't work, you can run the following command:

/function owg:config

Config

In the config menu, you can:

1. Set the glider spawn at your current location. The glider could for example the middle of your spawn island. Every player in a set range around this glider spawn will receive the one way glider. If you've already set a glider spawn, this button will remove the old glider spawn and create a new one at your current location. It is currently not possible to have multiple glider spawns.
2. Set the range. The range defines the radius, starting at the glider spawn, in which a player is given thhe one way glider and in which the one way glider will not be removed. It is recommended that the rang is set slightly larger than for example your spawn island, so that players can easily leave the spawn island with the one way glider equipped. Any player on the ground that is not in the range you've set, will loose their one way glider. When configuring the range, don't forget to click the save range button!

Known issues:

1. The slider in the config menu does not show the current range.

Anti exploit

The barrier glider will always get removed when in any inventory slot except the chestplate slot and if it is dropped. As soon as the player touches the ground, the barrier will also get removed from the chestplate slot.
The same thing applies to the unbreakable and glider attributes.
That way, this feature should not be exploitable.
