Falling Sand Game Template - Pixel Simulation v1.1.6 (03 Nov 2025) is a foundational template for building falling sand simulations in Unity. It leverages DOTS (Data-Oriented Technology Stack) to simulate thousands of pixels simultaneously, enabling high-performance, multi-threaded execution. Each pixel has individual properties and supports a range of predefined materials including Lava, Oil, Sand, Water, Rock, Wood, and Acid. The template features smooth sub-pixel camera movement, eliminating jumpy transitions for a more natural user experience.
The simulation is optimized for speed through DOTS, though extending the template requires familiarity with the Jobs system and BURST. Users can easily generate levels by drawing them in PNG format and configuring them via scriptable objects in the Unity Editor. The pixel-based world is rendered onto a simple quad, allowing seamless integration with scene objects and post-processing effects. Pixel-based collider generation enables characters to walk naturally on surfaces like sand or water.
A demo level is included in the package, accessible via Kamgam/SandGame/Addressables/Level1. The template comes with full source code, promoting transparency and developer accessibility. It supports Unity 2021.3 and later versions, including Unity 6, and is compatible with LTS releases. While it may work on earlier versions, those are not officially tested. The template is cross-platform, supporting PC, mobile, and WebGL, with performance optimized for modern devices—achieving 30 fps on older phones and 60 fps on mid-level devices. It works with all major render pipelines, including Built-in, URP, and HDRP.
