protected bool HasBuffer<T>(Entity entity) where T : struct, IBufferElementData
Parameters
The Entity object.
Returns
Type | Description |
|---|---|
| bool | True, if the specified entity has the component. |
Remarks
Always returns false for an entity that has been destroyed.
Use this method to check if another entity has a dynamic buffer of a given IBufferElementData type using its Entity object.
When iterating over entities coming from a query, avoid using this method with the current entity in the set. It is generally faster to change your query methods to avoid optional components.
When you call this method on the main thread, it invokes EntityManager.HasBuffer.
This lookup method results in a slower, indirect memory access. When possible, organize your data to minimize the need for indirect lookups.
