# Triggering the screens

#### Triggering a Blood Screen from Your Scripts

Activating a blood screen effect from your own scripts is straightforward and highly modular. First, retrieve a reference to the **`BSP_Manager`** component in your script:

```csharp
public BSP_Manager bspManager;
```

Once you have the reference, you can trigger the screen effect using the following methods:

| Method                       | Description                                         |
| ---------------------------- | --------------------------------------------------- |
| `ShowEffect()`               | Triggers a screen effect with optional flash.       |
| `StartEffectCycle()`         | Begins continuous effect cycles (e.g., low health). |
| `StopEffectCycle()`          | Ends continuous effect cycles.                      |
| `ActivateFlash(float alpha)` | Manually activates flash overlay.                   |
| `DeactivateFlash()`          | Manually deactivates flash overlay.                 |

This allows you to integrate BSP seamlessly into your gameplay logic—whether you're responding to damage, environmental hazards, or any custom event.

> 💡 **Tip:** You can easily integrate this logic into your existing game scripts for full control over visual feedback based on gameplay events.
