    Method RequireForUpdate

    RequireForUpdate(EntityQuery)

    Adds a query that must return entities for the system to run. You can add multiple required queries to a system; all of them must match at least one entity for the system to run.

    Declaration
    public void RequireForUpdate(EntityQuery query)
    Parameters
    Type Name Description
    EntityQuery query

    A query that must match entities this frame in order for this system to run.

    Remarks

    Any queries added through RequireforUpdate override all other queries cached by this system. In other words, if any required query does not find matching entities, the update is skipped even if another query created for the system (either explicitly or implicitly) does match entities and vice versa.
