Panels are a Portal element in Mari0: SE. They can be used to make non-portalable tiles toggle portalability on an input. For whatever reason, they can not be used to make portalable tiles non-portalable.
They were obviously an afterthought, having very basic graphics and a tooltip suggesting they would have been removed later. Additionally, their behavior is somewhat buggy, as blue portals will not be erased if the tile becomes non-portalable, yet orange portals will.
Other Uses Edit
- As they only affect one side of a block, they can be used to create a tile that is only portalable in one direction, simply by having it start white and never triggering it.
- They can be combined with pre-placed Portals to create portal doors immune to player interference.
