Animate blur effects (Unity PRO)

Questions & Answers
1

I see some indie games has a cutscene in it. Like when he wakes up, the blur effect used in it and the blur increase and decrease. Is it possible to animate the blur? I want to make in-game cutscene.

Do I need a script to do this?

Here’s an example. In this C# example, you’ll adjust the blur amount by pressing +/- on the num key pad. When blur is at minimum, it will be disabled, otherwise, enabled.

using UnityEngine;
using System.Collections;

public class Example : MonoBehaviour 
{
	float min = 0;
	float max = 5;
	float blur;
	float increment = 0.1f;
	
	void Awake()
	{
		blur = GetComponent<BlurEffect>().blurSpread;	
	}
	
	void Update()
	{
		GetComponent<BlurEffect>().blurSpread = blur;
		if(Input.GetKey (KeyCode.KeypadPlus) && blur < max)
			blur += increment;
		if(Input.GetKey (KeyCode.KeypadMinus) && blur > min)
			blur -= increment;
		if(blur <= min)
			GetComponent<BlurEffect>().enabled = false;
		else
			GetComponent<BlurEffect>().enabled = true;
	}
}
