| Note: This feature is for ZScript only. |
The LinePortal struct stores information pertaining to a specific portal linedef. Such as its' alignment, rotation, and attributes.
Fields
- Line mOrigin: The linedef that created the portal.
- Line mDestination: The other linedef which the portal leads to.
- Vector2 mDisplacement: The difference between the mDestination and mOrigin lines' XY positions. This is only relevant for static/PORTT_LINKED portals.
- UInt8 mType: The type of portal that this line portal is. Possible values include:
- PORTT_VISUAL: The portal is purely visual and not traversable at all. Such as a portal used as window.
- PORTT_TELEPORT: The portal is a teleport only portal. This is the most basic type of traversable portal. Not allowing for sound or light traversal, being detectable by the automap etcetera.
- PORTT_INTERACTIVE: More or less the same as above. But can also be recognized as a portal by portal aware functions like Vec3Offset and Vec2Angle.
- PORTT_LINKED: The two portals are statically linked with each other. Meaning that they cannot be changed or have any automatic plane alignments.
- PORTT_LINKEDEE: Eternity-compatible version of PORTT_LINKED, used for Eternity portal specials translated by XLAT. For more information, check Line_SetPortal.
- UInt8 mFlags: The line portals' flags. Possible values include:
- PORTF_VISIBLE: The portal is a visible-type one. (Verification needed)
- PORTF_PASSABLE: The portal is passable by actors and hitscans.
- PORTF_SOUNDTRAVERSE: Monster hearing can traverse through this portal.
- PORTF_INTERACTIVE: The portal is an interactive-type portal.
- PORTF_POLYOBJ: The portal is attached to a polyobject.
- PORTF_TYPETELEPORT: Implies PORTF_VISIBLE, PORTF_PASSABLE, and PORTF_SOUNDTRAVERSE.
- PORTF_TYPEINTERACTIVE: Implies PORTF_VISIBLE, PORTF_PASSABLE, PORTF_SOUNDTRAVERSE, and PORTF_INTERACTIVE.
- UInt8 mDefFlags: The flags the portal spawned with. Since non-static portals can have their flags changed at runtime. This field can be used to check the portals' original attributes.
- UInt8 mAlign: What sector plane the line portal is automatically aligned to. Only PORTT_VISUAL and PORTT_TELEPORT portals support this. Possible values include:
- PORG_ABSOLUTE: The portal has no alignment. This is always the default for non visual and teleporter portals.
- PORG_FLOOR: The portal is aligned to the floor plane.
- PORG_CEILING: The portal is aligned to the ceiling plane.
- double mAngleDiff: The angle difference between mDestination and mOrigin. This is always zero for linked/static portals.
- double mSinRot: The sine rotation of the portal, based on mAngleDiff. Used by non-static portals to position raycasts and actors properly on the other side of the portal. This is always zero for linked/static portals.
- double mCosRot: The cosine rotation of the portal, based on mAngleDiff. Used by non-static portals to position raycasts and actors properly on the other side of the portal. This is always 1.0 for linked/static portals.
