 # helios::engine::mechanics::lifecycle::systems

 

 Systems for processing entity lifecycle transitions.

 

 ## Overview

 

 This module provides systems that process lifecycle-related components each frame. The primary system handles delayed component activation by decrementing timers and enabling components when their delay expires.

 

 ## Key Classes

 

 | Class | Purpose |

 |-------|---------|

 | `DelayedComponentEnablerSystem` | Processes delayed activations each frame |

 

 ## System Behavior

 

 Each frame, the system:

 1 Iterates all entities with `DelayedComponentEnabler`

 2 Decrements each deferred component's timer by `deltaTime`

 3 Enables components whose timers reach zero

 4 Removes activated entries from the deferred list

 

 ## Scheduling

 

 Schedule in the gameplay phase after spawn systems but before collision/physics:

 

 ```cpp

 gameLoop.addSystem<DelayedComponentEnablerSystem>(Phase::Gameplay);

 ```
