Eternal Crusade: Resurrection
ECR is the resurrection of an online third-person shooter video game Eternal Crusade.
This project can be used as a template for creating a similar genre game, and ECRCommon module contains functionality that may be useful for a wide range of games.
Check out our Wiki for using this game code "core" and some useful UE dev tips!
Features
- C++ Unreal Engine 5 project
- Customization system for modular characters (material customization, mesh customization)
- Epic Online Services P2P matchmaking (users can create their own matches), including Linux Dedicated Servers
- Python Scripts for automation of restoring non-exportable or hardly-exportable data for an unpacked UE4 game (socket data, maps data, materials, references to materials within meshes)
- Enhanced Input Subsystem is used for input (borrowed from Lyra)
- 3rd person multiplayer shooter and melee combat system based on Lyra's GAS, including combat vehicles
- Plugin for HTTP requests
- Replay Subsystem with all needed functions for Blueprint replay setup
- Gameplay Analytics Subsystem in a separate plugin for collecting them and sending to API endpoint
- Cross-platform code (was built for Windows, Linux, Android)
GAS differences from Lyra (5.0)
Large changes
- Vehicles are supported as pawns (ECRWheeledVehiclePawn)
- Ability Queue System allows to grab input while another ability (like stun) is active
- PawnData elements are defined in GameState and on Character as a spawn option, so it can be customizable, unlike Lyra, where it's defined by experience and is the same for all players
Medium changes
- Several attributes are used to consume damage (First shield, then health, then bleeding health)
- QuickBar component has multiple channels (e.g. one for ranged weapons, one for melee), can make many "quick bars"
- ECREquipmentManagerComponent is capable of hiding equipment by visibility channels (e.g. LeftHand, RightHand for two-handed weapon)
- Gameplay Abilities can asynchronously load montages for different skeletons using cosmetic tags without having to create multiple ability instances for them
- Can temporarily limit yaw and pitch in Pawn Control Component (former Hero Component), Lyra always limits pitch in camera mode
- Advanced interaction system allows interaction options to be set by actors in blueprints, makes possible interactions via input tags and overriding input mappings
- Advanced melee combat prediction system
Fixes and small changes
- A better nested directory structure
- Fixed a bug with improper spread cooldown activation on ranged weapons
- Shooting uses advanced tracing to get a point on the camera vector where pawn should aim from weapon actor, unlike Lyra, where shooting is done from camera
- GAS debugger correctly works on 3rd page, checking costs on abilities CDOs without producing errors in the log
GIT policy
In both this repo and ECRContent (in private access) master branch is locked, all work should be done
after creating a new branch based on dev
