Detailed Description

[AI] Represents a "geometry edge" in the LEGO Island world polygon/path system.

Extends LegoWEEdge. It contains extra geometry information such as edge normals, flags, triggers, and other geometry metrics. [AI] The class is used in path/boundary computations, LOD edge logic, physics, and geometry-based triggering. [AI] SIZE: 0x54 [AI] VTABLE: LEGO1 0x100db7f8 [AI]

Constructor & Destructor Documentation

◆ LegoWEGEdge()

LegoWEGEdge::LegoWEGEdge ( )

[AI] Constructs a LegoWEGEdge and initializes its member variables.

[AI]

Definition at line 12 of file legowegedge.cpp.

◆ ~LegoWEGEdge()

LegoWEGEdge::~LegoWEGEdge ( )

override

[AI] Destroys this edge instance and properly deallocates memory for associated dynamic members.

Definition at line 25 of file legowegedge.cpp.

Member Function Documentation

◆ FUN_1009aea0()

LegoS32 LegoWEGEdge::FUN_1009aea0 ( )

protected

[AI] Internal routine called by VTable0x04 for validity checking of polygon vertices and normal consistency.

Returns 0 for OK, negative for degenerate or nonplanar geometry. [AI]

Returns: Result code (0 OK, negative if error on geometry consistency) [AI]

Definition at line 221 of file legowegedge.cpp.

◆ GetEdgeNormal()

Mx4DPointFloat * LegoWEGEdge::GetEdgeNormal ( int index )

inline

[AI] Returns a pointer to the 4D edge normal at the given sub-edge index.

Used for plane intersection/testing. [AI]

Parameters

index Index of the edge normal in the edge's polygonal set [AI]

Returns: Pointer to the normal at the requested index. [AI]

Definition at line 75 of file legowegedge.h.

◆ GetFlag0x10()

LegoU32 LegoWEGEdge::GetFlag0x10 ( )

inline

Returns TRUE if the 'disabled' flag is not set, otherwise FALSE.

Used as a quick status/activation check for edge-flags. [AI]

Returns: TRUE if enabled, FALSE if disabled (bit5 cleared). [AI]

Definition at line 57 of file legowegedge.h.

◆ GetMask0x03()

LegoU8 LegoWEGEdge::GetMask0x03 ( )

inline

[AI] Returns a two-bit mask of the first two edge state flags (bit1, bit2).

Useful for quickly getting the basic state/type of this edge (e.g., path eligibility/state flags). [AI]

Returns: Bitwise OR of c_bit1 and c_bit2 flags. [AI]

Definition at line 98 of file legowegedge.h.

◆ GetName()

const LegoChar * LegoWEGEdge::GetName ( )

inline

[AI] Returns the name string of this edge, typically used for debugging and lookup.

[AI]

Returns: Pointer to a null-terminated string holding the edge name. [AI]

Definition at line 79 of file legowegedge.h.

◆ GetUnknown0x14()

Mx4DPointFloat * LegoWEGEdge::GetUnknown0x14 ( )

inline

[AI] Returns a pointer to the cached 4D normal or reference plane for the edge.

This vector is central for many operations like side detection, collision, and physics. [AI]

Returns: Pointer to m_unk0x14. [AI]

Definition at line 70 of file legowegedge.h.

◆ SetFlag0x10()

void LegoWEGEdge::SetFlag0x10 ( LegoU32 p_disable )

inline

[AI] Sets the enabled/disabled flag for this edge.

If p_disable is TRUE (nonzero), disables the edge (clears bit5). If FALSE, enables it (sets bit5). Used by path logic to dynamically disable/enable edges at runtime. [AI]

Parameters

p_disable Whether to disable (TRUE) or enable (FALSE) this edge. [AI]

Definition at line 85 of file legowegedge.h.

◆ VTable0x04()

LegoS32 LegoWEGEdge::VTable0x04 ( )

overridevirtual

[AI] Performs geometry calculations for the edge, sets up normals, center point, and trigger vectors.

Returns 0 for success, negative values for various errors. See implementation for details on error codes. [AI]

Returns: Result code (0 = OK, negatives = error). [AI]

Reimplemented from LegoWEEdge.
