Class WDTOcclusion

Namespace
WoWLib.Formats.WDT.Occlusion
Assembly
WoWLib.dll

A _occ.wdt occlusion satellite (WoD+), abstract over the client version: per-tile low-resolution heightmaps the renderer occludes against. Construct a concrete version with WDTOcclusion.for_version(expansion). See https://wowdev.wiki/WDT.

Constructors

WDTOcclusion()

public WDTOcclusion()

WDTOcclusion(WDTOcclusion)

Copy-construct: a deep copy of other (the C++ copy constructor).

public WDTOcclusion(WDTOcclusion other)

Parameters

other WDTOcclusion

Properties

Heights

The packed heightmap block (MAOH): the tiles' interleaved 17x17 + 16x16 int16 grids back to back, addressed by the index records' offsets (same layout as the WDL MARE payload). Empty for WMO-only maps.

public Vector<short> Heights { get; }

Property Value

Vector<short>

Indices

The tile index (MAOI): one record per tile with occlusion data, locating its heightmap inside heights. Empty for WMO-only maps.

public Vector<OcclusionIndex> Indices { get; }

Property Value

Vector<OcclusionIndex>

Mver

The file format version; 18 like the main WDT.

public uint Mver { get; set; }

Property Value

uint

Methods

Dispose()

Release the native object now. Optional: the finalizer releases it on collection anyway - dispose (or using) when you want native memory back promptly.

public virtual void Dispose()

EnsureValid()

Validate and raise on the first error instead of returning a report — the assert-style face of validate().

public void EnsureValid()

ForVersion(ClientVersion)

A fresh WDTOcclusion for an exact client version — the only axis that can name a Classic client, whose files follow the engine its build was cut on rather than its 1.15 / 4.4 version number.

public static WDTOcclusion ForVersion(ClientVersion version)

Parameters

version ClientVersion

Returns

WDTOcclusion

ForVersion(Expansion)

A fresh WDTOcclusion for the given era, as the family base — the dynamic twin of the typed Era factories.

public static WDTOcclusion ForVersion(Expansion era)

Parameters

era Expansion

Returns

WDTOcclusion

Read(byte[])

Deserialize file bytes into this entity, replacing its contents. Unmodeled chunks are preserved so an unmodified entity rewrites byte-for-byte.

public void Read(byte[] data)

Parameters

data byte[]

Validate()

Check the logical integrity contracts this file must satisfy to LOAD in the client — companion-chunk counts, index ranges, flag/presence coherence — which write() deliberately never enforces. Call it before writing when you want to know the result will load. A file read from a client and left unmodified reports no errors; warnings mark states real client files ship.

public ValidationReport Validate()

Returns

ValidationReport

Write()

Serialize this entity.

public byte[] Write()

Returns

byte[]
