Make Timer a component

[waynemwashuma]

Objective

Refactors the Timer to become a proper ECS component. It moves the Timer from a standalone type to a component that can be attached to entities and automatically updated by the engine's systems.

Solution

The solution involved restructuring the Timer implementation to follow ECS patterns:

• Moved Timer to components: Converted Timer to a component type
• Added system-based updates: Created system that automatically updates all Timer components
• Integrated with TimePlugin: Registered Timer as a component type and added the update system
• Maintained API compatibility: All existing Timer methods and functionality remain unchanged

Showcase

The Timer now works as a proper ECS component:

// Create entity with Timer component
commands
  .spawn()
  .insertPrefab([
    new Timer({
      mode: TimerMode.Repeat,
      duration: 10,
      speed: 1.0
    })
  ])
  .build()

// Timer is automatically updated by the engine
// No manual update calls needed
