Description
Please note: EARLY RELEASE, Subject to changes for further improvements and features. All feedback is welcome to help improve this asset.
UltraGameCore is a modular, network-ready character, camera and gameplay foundation focused on high‑performance third person experiences. It combines client prediction, server reconciliation, adaptive latency compensation, extensible movement styles, inventory & ability systems, vehicles/seating (add-on purchased seperately), camera control, aim assistance, IK, spawning and UI monitors into a coherent, customizable package.
Key Systems
1. Locomotion & Prediction
-
Multiple movement styles (Adventure, Combat, Tank, TopDown) switchable per character.
-
Hybrid server authoritative + client prediction: circular state/input buffers, reconciliation, residual or direct smoothing strategies.
-
Adaptive latency bias (jitter-responsive) + extrapolation for remote clients.
2.Camera Framework
-
Orbit / follow camera with obstacle avoidance, shoulder swapping, pitch/yaw limits.
-
Vehicle / seat pivot handoff, shake modulation, distance & collision search tuning.
-
Aim assist & crosshair UI integration (dead‑zone, LOS, distance falloff).
3.Inventory & Weapons
-
Networked inventory with weapon banks, clip restore policies, pickups (units, health, items).
-
Distinct weapon ordering, primary weapon logic, removal on depletion, tracer & projectile support.
-
JSON persistence option for state (editor tooling provided).
4.Ability System
-
Modular ability base class (e.g. Jump, SpeedChange, InventoryInteract, ItemDropper).
-
Supports cast variants (ray/sphere/capsule), runtime force impulses, interaction gating.
5.Seating / Vehicle Addon (optional)
-
Board/Seat management (multi-seat vehicles, IK hand/feet link roots, camera overrides).
-
Moving platform attach/detach with grace period, yaw follow, wheel/physics sync.
-
Integration with car controllers (RCCP, predictive car demos).
6.Game Modes Addon (optional)
-
Deathmatch managers (teams, damage callbacks, scoring).
-
Spawning coordinators, match lifecycle, name tags, scoreboard UI.
7.Animation & IK
-
Network animator predicted layer.
-
IK controller for hands, feet, look targets; selective bone engagement when not facing target.
-
Ragdoll / model handler hooks and state presets.
8.UI Monitors
-
Crosshairs, health, inventory interaction, scoreboards, messages, damage direction indicators, chat.
-
Signal-driven updates via lightweight dispatcher (decoupled architecture).
9.Networking Backbone
-
Uses Unity Netcode for GameObjects (RPCs, NetworkVariables).
-
TickManager integration for deterministic timing.
-
Latency sampling, jitter statistics, adaptive smoothing.
10.Extensibility & Events
-
State system (StatePreset / blockers) enabling layered behavior & conditional overrides.
-
Inspector-driven tuning: movement speeds, gravity multipliers, fall behavior, prediction/extrapolation thresholds, reconciliation ratios, smoothing Tau, adaptive jitter bounds, camera collision search, aim angle gates, magnetism, LOS layers, push force modes.
-
Easily swap movement style or camera constraints per prefab or at runtime.
-
Extend abilities by inheriting AbilityBase (custom targeting, cast geometries).
-
Add new weapon types by deriving from ShooterBase / CharacterWeapon.
-
Replace or augment UI via existing monitors or your own signal listeners.
-
Vehicle seating can be expanded (custom seat camera pivots, IK link roots, per-seat restrictions).
-
Modular add-ons (Seating Controller, Game Modes, RPG/AI) can be included or omitted—Base stays lightweight.
-
Platform attachment logic can be reused for elevators, ships, trains with minimal code changes.
-
Latency handling parameters (bias ranges, sample capacity, smoothing time) adjustable for different net conditions or genre pacing.
Suitable Genres
-
Third-Person Shooter / Tactical Shooter
-
Action Adventure / Narrative
-
Vehicle Combat & Racing (with Seating add-on)
-
Survival / Extraction
-
Arena & Hero Shooter prototypes
-
Action RPG (extend abilities, inventory, stats)
-
Co‑op PvE or PvP Hybrids
-
Sandbox / Simulation with character & vehicle interplay
Why It Helps
-
Eliminates months of groundwork: prediction, smoothing, camera, inventory, abilities, seating, spawning, UI.
-
Scales from prototype to production: swap movement styles, add vehicles, enable game modes without refactoring core.
-
Clean separation via signals & state objects facilitates feature gating, testing, and modular packaging.
-
Robust handling of latency & jitter improves feel in real multiplayer sessions.
-
Integration Notes
-
Drop character prefab with locomotion + camera + inventory.
-
Enable or disable addons via scripting symbols or assembly definitions.
-
Adjust reconciliation strategy (DirectSmooth vs ResidualInject) to match gameplay tolerance for snap vs drift.
-
Use provided editor tooling (inspectors, windows) for bank definitions, inventory JSON, seat setup.
Asset Store Positioning
-
Positioned as a mid/high-level systems layer (not just a controller script).
-
Encourages extension rather than fork—APIs stable, signals reduce direct dependency.
-
Addons decouple niche features (vehicles, modes) from core runtime for performance/minimal footprint.
UltraGameCore is a flexible, deeply tunable multiplayer character & gameplay foundation suited for shooters, action, vehicle and hybrid genres, emphasizing prediction quality, modular extension, and rapid feature layering through clean event and state abstractions.
