Mass Battle Framework - GPU Crowd Combat & Animation

MASS BATTLE FRAMEWORK

Build large two-team battles in Unity 6 URP without turning every soldier into a GameObject, Animator, Rigidbody or Canvas.

Mass Battle Framework is a source-included toolkit for solo developers and small teams creating strategy games, battle sandboxes, bullet-heaven encounters or other projects that need animated armies. It provides a reusable foundation for crowd movement, targeting, combat, animation, projectiles, LOD, hit presentation and visual effects, while leaving the characters, rules and game around it in your hands.

BRING YOUR OWN ARMIES

Use the included Model Baker to bring compatible character models and animation clips into the framework. Configure one to eight variants for Idle, Move, Attack and Death, plus up to eight named special-action pools. Build units from reusable Model, Animation, Behavior and Ability profiles so art, stats, traits, skills and presentation can be changed independently.

This modular workflow makes it practical to create infantry, ranged units, cavalry, monsters, flying units, siege units and heroes without rebuilding every new unit as a separate framework subsystem.

BUILT-IN GPU EFFECTS

The package includes 40 first-party GPU effects covering the 20-unit sample roster. GPU Effect Studio lets you preview, play, pause, scrub, fork, edit and create effects directly in the Unity Editor without entering Play Mode. The supplied generated effects can be previewed as-is and forked into editable copies before customization.

WHAT IS INCLUDED

• 20 ready-made Human Alliance vs Monster Horde unit definitions

• 40 first-party GPU effects and GPU Effect Studio

• Direct Battle and Castle Siege demonstration scenes

• Melee, ranged, cavalry, siege, aerial and special-action examples

• Configurable animation variants and named special-action pools

• Model-baking and modular authoring tools

• Readable C#, Compute Shader and URP shader source

• Public APIs, Quickstart, model/VFX documentation, performance guidance and current limitations

LARGE-BATTLE DEMONSTRATION

The Castle Siege demo opens with more than 400,000 units across 20 unit types in the supplied configuration. World capacity is configurable up to 1,000,000 entity slots. These figures describe a demo configuration and capacity ceiling, not a universal frame-rate guarantee. Practical results depend on hardware, models, effects, projectiles, resolution, camera coverage, battle composition and project settings.

VERIFIED BASELINE

• Unity 6000.1.4f1

• Universal Render Pipeline 17.1.0

• Windows x64 with DirectX 11

• Compute Shader and indirect drawing support required

• AsyncGPUReadback required for requested snapshots

Mass Battle Framework is a focused battle foundation, not a complete RTS template. Bring your own world, armies and gameplay ideas; use the included examples as a practical starting point. I will continue refining, documenting and expanding the same product as my own large-scale battle game evolves.
