FloatingDamageNumber.cs
A simple game Component that tracks time since creation and destroys its GameObject after one second. It stores a RealTimeSince and checks it each update, calling GameObject.Destroy() when the timer exceeds 1 second.
using Sandbox;
public class FloatingDamageNumber : Component
{
private RealTimeSince _timeSince;
protected override void OnAwake()
{
base.OnAwake();
_timeSince = 0f;
}
protected override void OnUpdate()
{
base.OnUpdate();
if ( _timeSince > 1f )
GameObject.Destroy();
}
}
