🔥 Overview SimpleFireSpread.CS is a lightweight and pipeline-agnostic fire spread system designed for Unity 6. It enables objects to catch fire, propagate that fire to nearby objects, and optionally self-destruct after burning. This system does not rely on shaders or render pipeline features and works with any render pipeline (HDRP, URP, Built-in)

• Works across all render pipelines (HDRP, URP, Built-in)

• Uses only C# scripting and Particle Systems

• Supports animated or moving objects

• Fire spreads based on proximity and layer

• Optional destruction after burning

• Supports fire prefab VFX for visuals

• The script keeps track of burn state using isBurning

• When ignited, a fireEffectPrefab is instantiated

• After burnDuration elapses, it:

  • Spreads to other objects in spreadRadius

  • Optionally destroys itself

Fire only spreads to objects with simpleFireSpread.cs on the same burnableLayer.
