The Horizontal Portals addon removes the restriction that portals must stand upright. With this addon installed, you can configure individual portal types to be built flat on the ground, flat against the ceiling, or in either orientation — opening up a whole new range of build styles and adventure map mechanics.
Horizontal portals do not support custom blocks as the portal frame.
The custom inside block (portal fill) and the lighter (ignition item) both
work correctly in horizontal mode, but the frame material must be a standard
Minecraft block.
Configuration
Add the HorizontalPortal key under the Addon section of the portal’s .yml configuration file:
Addon:
HorizontalPortal: '<input>'
Values
| Value | Behaviour |
|---|
false | Default behaviour — the portal can only be built vertically |
true | The portal can only be built horizontally |
both | The portal can be built vertically or horizontally, and a vertical instance can link to a horizontal instance of the same type |
Use both when you want players to be able to enter a portal from either
orientation and still arrive at the correct destination. Portals built in
different orientations but set to both will recognise and link with each
other normally.
