The Source Engine is a 3D game engine developed by Valve Corporation. Its unique features include a large degree of modularity and flexibility, an artist-driven, shader-based renderer, accurate lip sync and facial expression technology, and a powerful, efficient and completely network-enabled physics system.

The Source engine was first shown to the world by being the power-horse behind the hugely anticipated Half-Life 2 which was released in late 2004. Since then the Source Engine has been upgraded with the release of such titles as Half-Life 2: Lost Coast, Team Fortress 2 and the Left 4 Dead series to name a few.

Whilst it has been years since the release of the Source Engine they haven't yet unveiled a 'next-generation engine' as the Source engine is always updating and is just as relevant in the gaming world today if not more than when it debuted in 2004. It has been aided by the release of the free Source Development Kit (SDK) which include such features as HDR for developers to use in their projects. Hence the reasons stated we have yet to see 'Source Engine 2'.

On July 10th 2012, Valve released the 'Source Filmmaker' - a freeware client to allowed anyone to make movies inside the Source Engine. More information on the Source Filmmaker can be found here.

Below you can find a list of amazing features that the Source Engine boasts:

Renderer

  • Version 2.0 (and below) shaders, bump mapping, LOD on models and world
  • Author shaders with HLSL
  • Cube and environment mapping
  • Dynamic lights, vertex lighting and light maps, many light types including flickering, pulsing etc.
  • High-Dynamic Range lighting
  • Water with refraction and fresnel effects
  • Advanced particle system that can emit sprites or models
  • Projected shadows allow for a large number of characters per scene
  • Occluder entities for visibility blocking
  • Indoor/Outdoor environments
  • Deformable terrain
  • 3D skyboxes extend the horizon and add parallax on distant objects
  • Dynamically rendered organics (grass, trees etc)
  • Subdivision surfaces, diffuse & specular bump maps
  • Real-time radiosity lighting
  • Effects include but are not limited to: particles, beams, volumetric smoke, sparks, blood, environmental effects like fog and rain
  • Scalability
  • Dx6-Dx9 hardware supported

Materials System

  • Instead of traditional textures, Source defines sets of materials that specify what the object is made from and the texture used for that object. A material specifies how an object will fracture when broken, what it will sound like when broken or dragged across another surface, and what that object’s mass and buoyancy are. This system is much more flexible than other texture only based systems.
  • Materials can interact with objects or NPCs such as mud or ice for vehicles to slide/lose traction on.

Multiplayer Network Code

  • Time and gamer tested by millions of gamers around the world
  • Support for both LAN based multiplayer and Internet based multiplayer games
  • Prediction analysis for interpolating collision/hit detection
  • Optimizations for high-latency, high-packet loss 56k connections

Advanced Characters

  • Detailed and believable characters
  • Realistic eyes
  • Focus on player/object, not simply parallel views
  • Proper eye “bulge” for realistic eye reflections
  • Simulated musculature provides outstanding emotions, speech and body language
  • Language independent speech, characters can naturally speak in many languages
  • Skeletal/bone system for animation
  • Layered animation system can synthesize complex animations out of several pieces

It's been almost a year since our game entered beta, and 9 months since Day of Infamy's launch. Since that time we've been hard at work developing free content updates and new features for the game. We've released a large number of new maps, revamped our rank systems, added new units, developed a new foliage system and were lucky enough to be featured on our own Steam free weekend!

It's important to us to continue to support the community and our games by releasing with free content updates. In that spirit, it's time to take a look at what's coming in our last free update this year!

New Map: Flakturm

Our new map, Flakturm is based on a series of German anti-aircraft towers (otherwise know as flak towers) built during WWII. Our tower is modeled after the Flakturm VII G-Tower in Augarten, Vienna.

The area outside the flak tower is inspired by the urban area surrounding Flakturm V in Stiftkaserne, Vienna. Flakturm VII was the 3rd generation of flak tower design. It was originally equipped with eight 128mm guns and thirty-two 20mm guns. This generation of flak tower could double as a bunker that could hold 20,000 people. The tower is now home to thousands of pigeons that make their nest inside the structure.

Our development team was inspired by these ominous structures and wanted to use the setting to try a different style of map than would focus on indoor combat.

"I was searching for a unique setting at the time to build a map around," says Day of Infamy's lead developer Christiaan Bakker. "We've had many maps that involve the traversal of urban areas, plains, hills and forests. I was hoping to find a location that would offer something new. In one of the fan-managed DOI Discords I spotted people posting some images of the flak tower in Augarten and it caught my eye. A level that involves mostly the interiors of a cylindrical tower? Moving up a massive building instead of crossing the farmlands. The gameplay contrast is huge when compared to our existing collection of maps. And it's technically a night map, the first one in Day of Infamy's official lineup so far."

Instead of our traditional maps that feature an outdoor environment, Flakturm requires teams to coordinate and push together through small indoor choke-points. Engineers may be necessary to blow up certain doors, creating new points of entry for the rest of the team.

"We expect the map will probably be a pretty polarizing," says Bakker "Some people will love the high intensity confrontations they have to deal with in the tower while others may feel lost trying to cope with all the chaos."

We highly encourage teams to use in-game voice to communicate which choke point they are defending or pushing. Also be sure to use the areas outside the more obvious center stairwell if you want to use flanks to breach the upper levels of the structure.

New Feature: Droppable Items


While we're big fans of Day of Infamy's Officer/Radioman mechanic, we felt it was important to provide that teams weren't just reliant on a couple players for support. That's why we're implementing droppable items such as the ammo pouch. Support players can drop ammo pouches for teammates, making it easier to refill ammo, especially in indoor areas. We suggest coordinating with your team and let other team members know when you need ammo!

New Feature: 64-Bit Support


In order to improve capability and performance, we've upgraded Day of Infamy's engine to support 64-bit for Windows and OSX users (Linux users may get a 64-bit update in future revisions of the game). 64-bit allows us to access more than 2GB of ram which should improve performance and stability. Modders should also see a benefit, as mods loaded on top of our current ram footprint, and 64-bit should allow users to push past the memory limit.

Update coming Soon!


We'll be talking more about the changes to the game with our development team on our upcoming weekly Twitch stream Thursday December 14th @ Noon EST, so please join in for that! We'll be launching soon, so pay attention to our social media accounts for new info about the update and its release!

That is a stupid question because no one can know what engine is the best for "your game", all we can do is suggest the engine we like the most, but sometimes what we like is not "the best".
The only way for you to know, what is the best engine for your game, is for you to experiment with them, and imo the best engine for any game, is the engine we as a developer/moder know the best, trying to find a engine perfect for your game is stupid and is the reason that many wannabe game developers never release anything.

Even tho it is aging and it is beginning to show its weakness comparred to other more modern engines, it is still my most preferred engine and the only one I was able to get into succesfully. And with all of the updates Valve is giving it, I think the source engine will be with us for a long time. I wouldn't really recommend this for a commerical product, just because there are so many more modern engines out there that will be a lot easier in the long run (like UDK), but all of the commercial games…
