EntityQueryBuilder The builder object that invoked this method.
Add absent component types to the query.
To match the resulting query, an archetype must not have any of the absent components (whether they are disabled or enabled).
There are several ways to exclude components from a query:
- WithAbsent<T>() matches all entities in chunks that do not have T at all.
- WithDisabled<T>() matches chunks that must have T, but only matches entities where T is disabled.
- WithNone<T>() matches both of the above cases: either the component isn't present at all, or it is present but disabled.
WithAbsent accepts up to seven type arguments. You can add more component types by chaining calls together.
To add component types that are not known at compile time, use M:Unity.Entities.EntityQueryBuilder.WithAbsent@@@@1(@@@@0@)
Component types added using WithAbsent are never written to. If the AccessMode field of the
provided component type is ComponentType.AccessMode.ReadWrite, it will be forced to
ComponentType.AccessMode.ReadOnly in the final query.
| Parameter | Description |

| componentTypes | A list of component types that implements T:Unity.Collections.INativeList@@1. For example, T:Unity.Collections.NativeList@@1 or T:Unity.Collections.FixedList64Bytes`1 |
