Method AddSharedComponentForEntityQuery

AddSharedComponentForEntityQuery<T>(EntityQuery, T)

Records a command to add a shared component to all entities matching a query.

Declaration

public void AddSharedComponentForEntityQuery<T>(EntityQuery entityQuery, T component)
    where T : struct, ISharedComponentData

Parameters

Type	Name	Description
EntityQuery	entityQuery	The query specifying which entities to add the component value to.
T	component	The component value to add.

Type Parameters

Name	Description
T	The type of shared component to set.

Remarks

The set of entities matching the query is 'captured' in the method call, and the recorded command stores an array of all these entities.

Entities which already have the component type will have the component set to the value.

Behavior at Playback: Will throw an error if one of these entities is destroyed before playback. (With safety checks enabled, an exception is thrown. Without safety checks, playback will perform invalid and unsafe memory access.)

Exceptions
