tick

public void tick(float dt,
 int index,
 @Nonnull
 ArchetypeChunk<EntityStore> archetypeChunk,
 @Nonnull
 Store<EntityStore> store,
 @Nonnull
 CommandBuffer<EntityStore> commandBuffer)

Description copied from class: EntityTickingSystem

Required reading: CommandBuffer

Called once per world tick for each 'entity' inside of an ArchetypeChunk with an Archetype that fulfills the Query provided by QuerySystem.getQuery()}.

If EntityTickingSystem.isParallel(int, int) returns true then this is called from a worker thread in the thread pool NOT from the world thread. When working with a parallel system special care must be taken to ensure data that is accessed is done so in a thead safe manor and that all components that have data that is modified are present in the ReadWriteArchetypeQuery.getWriteArchetype(). TODO: Expand docs to talk more about how other query types tie into this.

To access component data when using this method you should use the following:

var component = archetypeChunk.getComponent(index, componentType);

Specified by:

tick in class EntityTickingSystem<EntityStore>

Parameters:

dt - The delta time in seconds.

index - The index of the entity in the ArchetypeChunk.
