Method WithPresentRW

WithPresentRW<T1>()

Add required component types to the query with ReadWrite mode, whether they are enabled or disabled.

Declaration

[GenerateTestsForBurstCompatibility(GenericTypeArguments = new Type[] { typeof(BurstCompatibleComponentData) })]
public EntityQueryBuilder WithPresentRW<T1>()

Returns

Type	Description
EntityQueryBuilder	The builder object that invoked this method.

Type Parameters

Name	Description
T1	A required ReadWrite component type

Remarks

If a query uses the FilterWriteGroup option, you must use WithPresentRW to specify the query's writeable required components. Refer to the write groups guide for more information.

To match the resulting query, an Entity must have all of the query's required component types, regardless of whether they are enabled or disabled. To match required types only if they're enabled, use WithAllRW<T1>(). To match required types only if they're disabled, use WithDisabledRW<T1>().

WithPresentRW accepts up to two type arguments. You can add more component types by chaining calls together.

var query = new EntityQueryBuilder(Allocator.Temp)
    .WithAll<Friction>()
    .WithAllRW<ObjectPosition, ObjectVelocity>()
    .WithAllRW<ObjectRotation, ObjectRotationSpeed>()
    .Build(this);

To request read-only access to the reference component(s), use WithPresent<T>(ref T)

WithPresentRW<T1, T2>()
