Photon 2: Emergency Systems Platform

Photon 2 is a new platform for Garry's Mod police cars, fire trucks, ambulances, and all other types of emergency vehicles. It provides high-quality emergency lighting, sirens, scene lighting, standard vehicle lighting, and more – all with unparalleled realism.

Create your very own emergency vehicles in single player, or use it in multiplayer as the best emergency lighting system (ELS) available in Garry's Mod.

Photon 2 is an all new version of the original Photon and was rewritten from the ground up.

CLICK HERE to download the Starter Package

As Photon 2 is merely a platform, the Starter Pack is required for all of Photon 2's demonstrator vehicles to work correctly. If you continue to see error models, verify that you don't have any of the addons disabled.


To showcase Photon 2's features and capabilities, several demonstrator vehicles are included and available when the Starter Package collection is subscribed to. Most demonstrators are highly-detailed recreations of real-world emergency vehicles. They feature 4K liveries (skins) and use accurate equipment, sirens, and flash patterns as much as possible. Each demonstrator is also equipped with normal vehicle lighting.

The code for each vehicle is easily browsable[github.com] on the Photon 2 Github repository. You are free to reuse and implement any code included in these demonstrators.

Current Demonstrator Vehicles:

• Arvada, CO Police Department - 1991 Chevrolet Caprice
  
• Boulder Police Department - 2020 Ford Police Interceptor Utility
  
• Boulder County Sheriff's Office - 2020 Ford Police Interceptor Utility
  
• Colorado State Patrol - 2021 Dodge Durango Pursuit

• Do I need delete/uninstall Photon LE (Legacy)?
  No, Photon 2 is fully independent and can be safely run alongside Photon LE.
  
  
• Will old components/vehicles/sirens work in Photon 2?
  While this was initially planned, it is now very unlikely. Photon 2's core assets are almost universally brand new, so using them as 1:1 replacements for their Photon LE counterparts is not possible.
  
  Developer utilities are being made to make the conversion process smoother, however.
  
  
• Why am I seeing ERROR models on cars?
  You're missing required content or you have one or more required addons disabled. Because it is not possible for addons to automatically subscribe to other required addons, it is important to read addon descriptions so you know the prerequisites.

• Offers emergency warning lights, scene illumination, traffic direction, cruise lighting, sirens, and more for police cars, fire engines, service vehicles, and all varaties of emergency vehicles.
  
  
• Supports normal vehicle lighting, including headlights, parking lights and turn signals. Modern vehicles equipped with realistic daytime-running lights with automatic headlights that activate in dark environments.
  
  
• Support for player-swappable equipment.
  
  
• Written from the ground-up to resolve Photon LE's problematic structure and code patterns.
  
  
• Incredibly modular framework unifies functionality of all different lighting types (primary, auxiliary, traffic, basic lighting, etc.)
  
  
• Dedicated Photon entities are now used instead of actual vehicle entities, allowing Photon to be used on any type of entity when configured, and drastically reducing the chance of conflict with other addons.
  
  
• Robust component inheritance support allows you to easily construct new components based on existing ones without redundant copying and pasting.
  
  
• Edit nearly every aspect of any component when adding it to a vehicle in the vehicle file itself, including flash patterns and inputs. No more needing to create dedicated component files every time you want custom behavior.
  
  
• User-friendly menus and windows make the addon much more approachable for non-enthusiast users.
  
  
• Highly responsive developer workflow allows for vehicle and component creation/editing with minimal need to ever respawn or restart. Simply save the file and immediately see changes take effect.
  
  
• Support for different types of engine lighting (2D sprites, 3D meshes, dynamic lights, projected textures and sub-materials)
  
  
• Support for model animations (via bones, poses, and animations, and more)
  
  
• Extremely customizable control configuration, allowing for any type of hardware button to be bound (as long as the game itself recognizes it), the ability to have multi-button combination commands, and even multiple input profiles that can be created, swapped, and assigned to individual vehicles as desired.
  
  
• New, high-fidelity siren sounds (made by me for Photon 2) including modern tones from SoundOff Signal, Federal Signal, Whelen and Code 3. Many new sirens are planned and in progress.
  
  
• Customizable HUD that can be easily moved around the screen by simply clicking and dragging.
  
  
• Component and siren library browsers allow for inspecting and previewing all installed Photon 2 content.
