Method HasBuffer
HasBuffer<T>(Entity)
Checks whether an entity has a dynamic buffer of a specific IBufferElementData type.
Declaration
public static bool HasBuffer<T>(Entity entity) where T : unmanaged, IBufferElementDataParameters
| Type | Name | Description |
|---|---|---|
| Entity | entity | The Entity object. |
Returns
| Type | Description |
|---|---|
| bool | True, if the specified entity has the component. |
Type Parameters
| Name | Description |
|---|---|
| T | The IBufferElementData type. |
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 a set of entities via IJobEntity or Query<T1>(), avoid using this method with the current entity in the set. It is generally faster to change your entity query methods to avoid optional components; this may require a different iteration construction to handle each combination of optional and non-optional components.
this method gets replaced with component access methods through BufferLookup<T>.
In both cases, this lookup method results in a slower, indirect memory access. When possible, organize your data to minimize the need for indirect lookups.
