Detailed Description

[AI] Represents an advanced edge in the LEGO Island geometry system, with direction, flags, and geometric query utilities.

[AI] This is an extension of LegoEdge, featuring enhanced geometric capabilities. This structure associates an edge with additional information such as directionality (normal vector), flags indicating properties per-face, and several helper functions for geometry intersection and metric queries. Seen in the path- and world-edge system of LEGO Island.

Constructor & Destructor Documentation

◆ LegoUnknown100db7f4()

LegoUnknown100db7f4::LegoUnknown100db7f4 ( )

[AI] Constructs a new edge object with zero-initialized per-face flags and direction/normal vector.

Definition at line 7 of file legounkown100db7f4.cpp.

Member Function Documentation

◆ BETA_1004a830()

LegoU32 LegoUnknown100db7f4::BETA_1004a830	(	LegoWEGEdge &	p_face,
		LegoU8	p_mask
	)

[AI] Tests whether a WEG-edge meets complex mask and flag criteria for this edge, depending on mask and which face is referenced.

Parameters

p_face	[AI] The WEG-edge being queried.
p_mask	[AI] Bitmask to match against the face's mask.

Returns: TRUE if edge matches mask and flags conditions; otherwise FALSE. [AI]

◆ BETA_100b53b0()

LegoU32 LegoUnknown100db7f4::BETA_100b53b0 ( LegoWEGEdge & p_face )

[AI] Checks if a WEG-edge is connected to this edge with proper flagging for its side.

[AI] Used to quickly determine face-edge-side relations.

Parameters

p_face [AI] The WEG-edge to check.

Returns: TRUE if present according to correct flag (c_bit1/c_bit2), otherwise FALSE. [AI]

◆ DistanceBetweenMidpoints()

LegoFloat LegoUnknown100db7f4::DistanceBetweenMidpoints ( const LegoUnknown100db7f4 & p_other )

[AI] Returns the Euclidean distance between the midpoints of this edge and another edge.

[AI] Both midpoints are computed and then their distance measured, for geometry LOD or region grouping.

Parameters

p_other [AI] The other edge.

Returns: Distance between midpoints. [AI]

◆ DistanceToMidpoint()

LegoFloat LegoUnknown100db7f4::DistanceToMidpoint ( const Vector3 & p_vec )

[AI] Calculates linear distance from a vector position to the 3D midpoint of the edge.

[AI] Used for proximity/metric queries.

Parameters

p_vec [AI] Position to compare against midpoint.

Returns: Euclidean distance from input point to the midpoint of this edge. [AI]

◆ FUN_1002ddc0()

LegoResult LegoUnknown100db7f4::FUN_1002ddc0	(	LegoWEEdge &	p_f,
		Vector3 &	p_point
	)		const

[AI] Calculates the edge normal for use from the given face, negating it if called from faceA.

[AI] Provides outward-facing edge normal as a vector for the specified edge; reversed for one side, used for collision, lighting, or traversal logic.

Parameters

p_f	[AI] The face from which the query is made.
p_point	[AI] Output vector for the face's normal.

Returns: Returns SUCCESS on completion. [AI]

◆ FUN_10048c40()

LegoU32 LegoUnknown100db7f4::FUN_10048c40 ( const Vector3 & p_position )

inline

[AI] Tests if a position is on this edge based on its direction and points, within a precision threshold.

[AI] Tests for geometric containment: whether the given position is on/along this edge segment (using direction/normal and tolerance).

Parameters

p_position [AI] The position to test.

Returns: TRUE if the point lies on the edge (within a tolerance), else FALSE. [AI]

◆ GetMask0x03()

LegoU32 LegoUnknown100db7f4::GetMask0x03 ( )

[AI] Returns a mask of flags relevant to the two faces (bits 0 and 1: c_bit1, c_bit2).

Returns: The flag mask for face assignment. [AI]

◆ OtherFace()

LegoWEEdge * LegoUnknown100db7f4::OtherFace ( LegoWEEdge * p_other )

[AI] Returns the opposite face pointer to the one passed in.

[AI] Call with a face pointer: gets the "other" face at the edge for traversal/type queries.

Parameters

p_other [AI] Known face.

Returns: Returns pointer to the other (not passed-in) face. [AI]

◆ SetFlags()

void LegoUnknown100db7f4::SetFlags ( LegoU16 p_flags )

[AI] Directly sets the internal flags value.

Parameters

p_flags [AI] Value to assign to m_flags.

LegoUnknown100db7f4::m_unk0x28

[AI] Represents the edge's direction/normal vector or outward face normal.

[AI] Used repeatedly for face-based normal queries and edge positioning.
