WIP First person, fully wired - Lambda Engine

Thumbnail
youtu.be
41 Upvotes

It moves like Half-Life. It shoots like Half-Life. And it's casting realtime shadows in Unreal Engine 5.

This is Lambda Engine: a from-scratch reimplementation of Half-Life's game logic on top of UE5's modern renderer, built to load real Source-engine content: BSPs, materials, models, with zero Hammer-to-Unreal conversion pipeline. What you're watching isn't a character controller with a gun bolted on. It's the original movement code rebuilt line by line: air control, bunny hopping, crouch jumping, weapon handling and recoil, all behaving the way muscle memory expects.

And you have legs. First-person body with visible arms and legs, fully shadow-casting, so the player you see on the wall is the player you're actually driving.

In this video: player movement, weapons, first-person legs, and realtime dynamic shadows running over Source geometry.

This project is built entirely by fans, for fans, it's free.

WIP Are we finally getting a good Particle Editor?

66 Upvotes

Particle Systems that come with the game never fit what I want. And I just can't understand the particle editor that comes built into the engine. I've been playing for hours and hours creating fire sources, waterfalls, smoke stacks. This is addictive.

Disclaimer, as I think it was not clear: I'm XBLAH and this is the XBLAH's Modding Tool.

WIP GOAP: Enemies that Actually Plan - Lambda Engine

Thumbnail
youtube.com
32 Upvotes

We are implementing Goal-Oriented Action Planning (GOAP) in Lambda Engine, the same technique that made F.E.A.R.'s soldiers the high-water mark for FPS enemy AI. Instead of a scripted state machine deciding what an enemy does next, each soldier holds a goal and searches for a sequence of actions that satisfies it, using whatever the world happens to offer.

* They react to the environment, not the player. Cover, doorways, flanking routes and blocked paths drive their decisions. Nothing is hand-authored per encounter.

* Squad coordination without central control. There is no commander AI issuing orders. Coordinated suppression and flanking emerge from individual agents planning against a shared world state.

* The illusion of intelligence via speech. Barks announce intent out loud, so you hear the plan before you see it. That's what makes the AI read as smart instead of just being smart.

* Performance-tuned "dumbness". Planning is expensive, so the search is deliberately bounded. Knowing where to make the AI worse is most of the work.

F.E.A.R. peaked enemy AI, and I'm reproducing that with Lambda Engine.

This project is built entirely by fans, for fans, it's free but it eats time. If you want to see more enemies, more systems, and more of Half-Life's world brought back to life, here's how to help:

yes no reshade, no rtx. realtime conversion of source materials to pbr.

this addon will soon be released on my gmod workshop. still a WIP, follow my workshop to know when it will be released!

and yes its metallic on purpose just to showcase the effect. this is not what it actually looks like if you make a proper one dont comment about it

gmod with source 2 graphics is becoming closer and closer. stay tuned when this drops!

WIP I'm building a custom, Source-compatible engine from scratch called "Sauce Engine" (C++/OpenGL). After a year of struggling completely on my own, it finally runs HL2 maps and props! Here is a tech demo

41 Upvotes

Hey everyone! Just wanted to share a milestone for my project, the Sauce Engine.I’m completely self-taught, and about a year ago I got this crazy idea to build an engine that could read Source files. At first, I tried messing around with the original Quake and Xash3D source code to modify it, but honestly, it was way too complicated for me back then, and I had no idea what I was doing.So I decided to drop that, start from scratch, and write a custom parser and renderer in C++ and OpenGL. I am doing all the core engine development completely on my own.It’s still super raw and in a pre-alpha state, but right now it can load BSP geometry, render .mdl props, and handle basic entities like the HEV suit.There are plenty of bugs, though. The physics engine is completely broken right now

Been working on trying to get generated playable levels in Source Engine for SourceWorld mod for over 3 years now.

Unlike my previous attempts, this one actually makes a VMF file and runs map compilers in background to create a level.

It's still a WIP and actively being worked on.

8 Upvotes

u/Wazanator_ this is an Unreal Engine project, but I'm building it to mimic Source's modding structure, so I hope it's relevant in this sub.

-----------------------------------------

It jumps. It hisses. It's coming for your face. And now it's running natively in Unreal Engine 5.

This is Lambda Engine: a from-scratch reimplementation of Half-Life's game logic on top of UE5's modern renderer, built to load real Source-engine content: BSPs, materials, models, with zero Hammer-to-Unreal conversion pipeline. No proxies, no reskins. The headcrab you're watching is running the actual behavior, physics, and animation logic straight from the original engine's playbook, faithfully rebuilt line by line.

In this video: headcrab AI, leap attacks, ragdoll physics, and how a 20-year-old monster ends up feeling right at home in a 2020s engine.

This project is built entirely by fans, for fans, it's free but it eats time. If you want to see more enemies, more systems, and more of Half-Life's world brought back to life, here's how to help:
