Method SwapComponents

SwapComponents(ArchetypeChunk, Int32, ArchetypeChunk, Int32)

Swaps the components of two entities.

Declaration

public void SwapComponents(ArchetypeChunk leftChunk, int leftIndex, ArchetypeChunk rightChunk, int rightIndex)

Parameters

Type	Name	Description
ArchetypeChunk	leftChunk	A chunk containing one of the entities to swap.
Int32	leftIndex	The index within the leftChunk of the entity and components to swap. Must be in the range [0,leftChunk.Count).
ArchetypeChunk	rightChunk	The chunk containing the other entity to swap. This chunk can be the same as the leftChunk. It also does not need to be in the same World as leftChunk.
Int32	rightIndex	The index within the rightChunk of the entity and components to swap. Must be in the range [0,rightChunk.Count).

Remarks

The entities must have the same components. However, this function can swap the components of entities in different worlds, so they do not need to have identical archetype instances.

Important: This method creates a sync point, which means that the EntityManager waits for all currently running jobs to complete before swapping the component. No additional jobs can start before the method is finished. A sync point can cause a drop in performance because the ECS framework might not be able to use the processing power of all available cores.
