Parameters
The World
Returns
Type | Description |
|---|---|
| SystemHandle | The instance's handle of system type |
Remarks
Important: This function creates a sync point if a system is created, which means that the EntityManager waits for all currently running Jobs to complete before creating the system, and no additional Jobs can start before the function is finished. A sync point can cause a drop in performance because the ECS framework may not be able to make use of the processing power of all available cores.
