## Description

FixedUpdate Input System

A utility System for polling input in an Update loop to use in a FixedUpdate loop without missing inputs in-between FixedUpdate ticks.

How to use it:

namespace Sandbox;

public sealed class ExampleComponent : Component
{
 private FixedUpdateInputSystem \_fixedInput;

 protected override void OnStart()
 {
 // Get a reference to the system.
 \_fixedInput = Scene.GetSystem<FixedUpdateInputSystem>();

 base.OnStart();
 }

 protected override void OnFixedUpdate()
 {
 // Query for input like normal.
 if ( \_fixedInput.Pressed( "jump" ) )
 {
 Log.Info( "Jump" );
 }

 base.OnFixedUpdate();
 }
}
