Spatial Transformation

A portal is a window linking to a transformed space. The spacial transformation can be translation, rotation, scale and mirroring.

This mod's teleportation is eye-based. If an entity goes through a portal, it will calculate the entity's eye position transformed by the portal and then place the entity by the transformed eye position.

Rotation Transformation

Commands related to rotation

Teleportation

After crossing a portal with rotation transformation, the player's camera may be tilted. Then the camera rotation will smoothly turn into a valid state.

This mod has special compatibility with Gravity Changer mod. With Gravity Changer mod, if you enable teleportChangesGravity to a portal, then your gravity direction will be automatically changed when crossing the portal. (teleportChangesGravity is disabled by default.)

About Gravity Changer Mod

The original Gravity Changer mod by Gaider10 (Andrew). Gaider10 (Andrew) stopped maintaining it.

In 1.18.2 you can use my fork of Gravity Changer .

In 1.19.2, ImmPtl is compatible with Gravity API .

In 1.19.3, use my fork of Gravity API .

Scale Transformation

Commands related to scaling

Teleportation

This mod has special compatibility with Pehkui mod. With Pehkui mod, if a player or an entity goes through a portal with scale transformation, it will be scaled. This is controlled by the portal property teleportationChangesScale. (teleportationChangesScale is enabled by default)

Mirror Transformation

Mirrors.

Teleportation

Mirrors do not allow teleportation. Because when the player goes into a mirror, the player itself should get mirrored. Currently there is no mod that provides the functionality of mirroring the player (imagine that the right hand appear on the left and turning right actually turns left).

However, you can create a fake-enterable mirror, by using command /portal turn_into_fake_enterable_mirror on a normal portal. Details about that command.
