This feature is by default not enabled and must be enabled via an INI option.
Unstuck allows you to well get Unstuck. Simply hold "R" to bring up the radial menu and choose Unstuck.
To combat abuse it has a long activation timer (adjustable) and a cooldown timer. (adjustable)
Climb mode:(default mode)
The climb mode will pop you up if your stuck in a floor and such. If you are in a mesh hole where you are stuck in the falling animation it will allow you to walk on nearly vertical surfaces (Will not be able to climb a castle wall for example) for a short period of time so you can just walk out of that hole.
Teleport Mode: This mode is to be considered as a WIP. This mode must be enabled Via an INI setting. This will replace the default climb mode. It is highly recommended to make sure undermeshing is turned off for this mode.
This mode will teleport your character forward 4 foundations and up or down if need be to the highest, or lowest if say your on a mountain side and looking down, place at that forward location. Example: You are in a locked building and can't get out and you use unstuck and 4 foundations forward you would still be in the same building or in another one it will put you on top of the building instead.
Cautions for this mode:
It may not work correctly in Very deep caves and put you under the mesh.
This mode will get you out of most all stuck situations but I caution admins on this mode as it can allow you to get to places you shouldn't be able to get to, like under the mesh.
This mode is highly recommended to NOT be used on Aberation as the map construction doesn't work well with how this mode functions.
