Given an entity in the target chunk, you can add a chunk component to the chunk using the EntityManager.AddChunkComponentData() function: EntityManager.AddChunkComponentData(entity) Otherwise, the component is treated as a general-purpose component instead of a chunk component. Use ComponentType.ChunkComponent or ComponentType.ChunkComponentReadOnly with these methods. You can also include chunk components as part of the EntityArchetype or list of ComponentType objects used to create entities and the chunk components are created for each chunk storing entities with that archetype. Chunk components cannot be added inside a Job, nor can they be added with an Entit圜ommandBuffer. You can add a chunk component directly, using an entity in the target chunk or using an entity query that selects a group of target chunks. public struct ChunkComponentA : IComponentData SetChunkComponentData (ArchetypeChunkComponentType, T)ĮntityManager.SetChunkComponentData (ArchetypeChunk, T)Ĭhunk components use the interface type IComponentData. HasChunkComponent (ArchetypeChunkComponentType ) GetChunkComponentData (ArchetypeChunkComponentType ) Chunk components also have their own ComponentType functions for use in defining entity archetypes and queries. The main differences between working with chunk components and general-purpose components is that you use different functions to add, set, and remove them. (If the entity is moved to a newly created chunk, then the value of the chunk component is copied from the entity's source chunk.) If you change the archetype of an entity such that it moves into a new chunk that happens to have the same type of chunk component, then the existing value in the destination chunk is retained. If you change the value of a chunk component using an entity in that chunk, it changes the value of the chunk component common to all the entities in that chunk.
Likewise, if you add a chunk component to an entity, that entity moves to a different chunk since its archetype changes the addition of the chunk component does not affect the remaining entities in the original chunk. Thus if you remove a chunk component from an entity, that entity is moved to a different chunk (possibly a new one). Chunk components use the interface types IComponentData.Īlthough chunk components can have values unique to an individual chunk, they are still part of the archetype of the entities in the chunk. For example, if you had chunks of entities representing 3D objects that are organized by proximity, you could store a collective bounding box for the entities in a chunk using a chunk component.

Adding a chunk of rcode code#
Within the code chunk, type the names of the investment_annual_summary and investment services_projects datasets to print them in the report.Add a new code chunk to the Markdown file, starting at line 14.In this exercise, let's take a look at the annual summary dataset as well as the other dataset we'll be using, investment services_projects. Previously, we looked at the investment annual_summary dataset we'll be using throughout the course. Transcribed image text: Adding code chunks to your file When creating your own reports, one of the first things you'll want to do is add some code! In the video, we discussed how you can add your own code by adding code chunks.
