Method CalculateBaseEntityIndexArrayAsync

CalculateBaseEntityIndexArrayAsync(AllocatorManager.AllocatorHandle, JobHandle, out JobHandle)

Asynchronously generates an array containing the index of the first entity within each chunk, relative to the list of entities that match this query.

Declaration

public NativeArray<int> CalculateBaseEntityIndexArrayAsync(AllocatorManager.AllocatorHandle allocator, JobHandle additionalInputDep, out JobHandle outJobHandle)

Parameters

Type	Name	Description
AllocatorManager.AllocatorHandle	allocator	The allocator used to allocate the output array.
JobHandle	additionalInputDep	A job handle which the newly scheduled job will depend upon, in addition to the dependencies automatically determined by the component safety system.
JobHandle	outJobHandle	An out parameter assigned the handle to the internal job that populates the output array.

Returns

Type	Description
NativeArray<Int32>	An array of integers, where array[N] is the index of the first entity in chunk N among the list of entities that match this query. The size of this array is given by CalculateChunkCountWithoutFiltering(). This array's contents must not be accessed until outJobHandle has been completed.

Remarks

Note that the chunk index used to access the output array's elements should be relative to the full, unfiltered list of chunks matched by this query. Most commonly, this is the chunkIndex parameter available within Execute(in ArchetypeChunk, Int32, Boolean, in v128).

This function will automatically insert dependencies any running jobs which could affect its output. For a blocking implementation, use CalculateBaseEntityIndexArray(AllocatorManager.AllocatorHandle).
