SboxSuperuser/Engine/Bodies/Burning.cs
A small component in SboxSuperuser's host-side engine. Ticks every 0.2s and applies fire-tagged damage to a target GameObject's IDamageable listeners, then destroys itself when the target is gone. It exists because FireDamage can't run on a client-owned player body.
using Sandbox;
namespace SboxSuperuser.Engine.Bodies;
/// <summary>
/// Burns a player from a host-owned object outside their body. FireDamage can't be used on the body itself:
/// anything inside a client-owned player is a proxy on the host, and FireDamage only runs where it isn't one.
