this[Entity]
Gets the IComponentData instance of type T for the specified entity.
public T this[Entity entity] { get; set; }
Parameters
The entity.
Returns
Type | Description |
|---|---|
| T | An IComponentData type. |
Remarks
Normally, you cannot write to components accessed using a ComponentLookup instance in a parallel Job. This restriction is in place because multiple threads could write to the same component, leading to a race condition and nondeterministic results. However, when you are certain that your algorithm cannot write to the same component from different threads, you can manually disable this safety check by putting the [NativeDisableParallelForRestriction] attribute on the ComponentLookup field in the Job.
this[SystemHandle]
Gets the IComponentData instance of type T for the specified system's associated entity.
public T this[SystemHandle system] { get; set; }
Parameters
The system handle.
Returns
Type | Description |
|---|---|
| T | An IComponentData type. |
