A way to easily pause the action while dialogs are up

StopTheAction.cs

using UnityEngine;

// @kurtdekker
//
// For stopping your game during instantiated / enabled dialogs.
//
// To use: put this script on things that you want to
// stop your game action when they appear, like dialogs.
//
// You only need one instance of this script per dialog.
//
// Then in your actual game move code, check it like so:
//
//	if (StopTheAction.IsPaused())
//	{
//		return;  // early return; we are paused
//	}
//
// or:
//	if (StopTheAction.IsRunning())
//	{
//		DoPlayerMovement();
//	}

public class StopTheAction : MonoBehaviour
{
	static int stopCount;

	public static bool IsPaused()
	{
		return stopCount > 0;
	}

	public static bool IsRunning()
	{
		return stopCount <= 0;
	}

	void OnEnable()
	{
		stopCount++;
	}
	void OnDisable()
	{
		stopCount--;
	}
