Method GetSingletonBuffer
GetSingletonBuffer<T>(bool)
Gets the value of a singleton buffer component. Note that if querying a singleton buffer component from a system-associated entity, the query must include either EntityQueryOptions.IncludeSystems or the SystemInstance component.
Declaration
[GenerateTestsForBurstCompatibility(GenericTypeArguments = new Type[] { typeof(BurstCompatibleBufferElement) })]
public DynamicBuffer<T> GetSingletonBuffer<T>(bool isReadOnly = false) where T : unmanaged, IBufferElementDataParameters
| Type | Name | Description |
|---|---|---|
| bool | isReadOnly | If the caller does not need to modify the buffer contents, pass true here. |
Returns
| Type | Description |
|---|---|
| Dynamic |
The singleton buffer. |
Type Parameters
| Name | Description |
|---|---|
| T | The buffer element type. |
Remarks
A singleton buffer component is a component of which only one instance exists that satisfies this query. There is no SetSingletonBuffer(); to change the contents of a singleton buffer, pass isReadOnly=false to GetSingletonBuffer() and then modify the contents directly.
Exceptions
| Type | Condition |
|---|---|
| Invalid |
Thrown if the number of entities that match this query is not exactly one. |
