详细描述

Incremental static collision projection of authoritative PixelWorld chunks.

The cache owns only process-local PhysicsLinks and revision metadata. Physics World owns all bodies/fixtures and PixelWorld owns all material cells. Sync is owner-thread affine, invokes no callbacks, and stages every replacement body before committing.

在文件 PixelWorldPhysics.h 第 173 行定义.

构造及析构函数说明

eve::pixelworld_physics::PixelTerrainCollisionCache::PixelTerrainCollisionCache ( const PixelTerrainCollisionCache &  )

delete

成员函数说明

bodyCount()

std::size_t eve::pixelworld_physics::PixelTerrainCollisionCache::bodyCount ( ) const

noexcept

Number of chunks currently owning a non-empty static collision body.

在文件 PixelWorldPhysics.cpp 第 638 行定义.

clearPhysics()

eve::Result< void > eve::pixelworld_physics::PixelTerrainCollisionCache::clearPhysics

(

eve::physics::World &

physicsWorld

)

Explicitly destroy every resolvable projected body and reset revision tracking.

在文件 PixelWorldPhysics.cpp 第 619 行定义.

引用了 eve::Diagnostic::error(), eve::Result< T >::failure(), eve::RuntimeHandle< PhysicsWorldHandleTag >::invalid(), eve::physics::World::runtimeHandle(), eve::StaleHandle , 以及 eve::Result< T >::success().

operator=() [1/2]

PixelTerrainCollisionCache & eve::pixelworld_physics::PixelTerrainCollisionCache::operator= ( const PixelTerrainCollisionCache &  )

delete

operator=() [2/2]

PixelTerrainCollisionCache & eve::pixelworld_physics::PixelTerrainCollisionCache::operator= ( PixelTerrainCollisionCache &&  )

defaultnoexcept

Operator =.

sourceRevision()

std::uint64_t eve::pixelworld_physics::PixelTerrainCollisionCache::sourceRevision ( ) const

noexcept

Last authoritative revision fully represented by this cache.

在文件 PixelWorldPhysics.cpp 第 637 行定义.

sync()

eve::Result< TerrainCollisionSyncReceipt > eve::pixelworld_physics::PixelTerrainCollisionCache::sync	(	eve::physics::World &	physicsWorld,
		const eve::pixelworld::PixelWorld &	pixelWorld,
		std::uint32_t	maximumFixturesPerChunk = 256
	)

Rebuild only chunks newer than the cached source revision.

参数

physicsWorld	Borrowed owner of static bodies.
pixelWorld	Borrowed authoritative material world.
maximumFixturesPerChunk	Positive deterministic complexity budget.

返回

Applied counters; failure destroys staged candidates and preserves prior cache entries.

备注

A live physics-world binding must be cleared explicitly before rebinding. If the old world has already expired, synchronization may safely discard its stale links and bind the replacement world.
