Old Cartoon Effects

Hello Everyone,

a few days ago I asked myself if it's possible to make the old cartoon flickering "effect" like in the black and white cartoon movies back in the 30s. But I have no clue how to make such a "flickering".

Does anyone know if it is possible? And if, can you describe how I can make those effects?

Thank you in advance.

So... basically a coroutine that periodically enables and disables a (black) Image component stretched over the whole screen?

That sounds ... interesting. How would I make this courotine? I also meant those flickering effects like those at the beginning of this cartoon: https://www.youtube.com/watch?v=lAkg-qd1Bhk (00:00 - 00:20) + the juddering camera. Thanks for your help.

 using UnityEngine.UI;
 
 public Image image;
 public float flickerTime = 0.1f;
 
 public void Start() {
      StartCoroutine("Flicker");
 }
 
 private IEnumerator Flicker() {
      while(true) {
           yield return new WaitForSeconds(flickerTime) ;
           image.enabled = !image.enabled;
      }
 }

Thank you for your help. I tried your code but it doesn't work. How can I get this code work or how should I "use" it? To which gameobject should it be added? Sorry for my questions but I'm new to coroutine and UI elements. Thank you in advance.

Here is the full script:

 using UnityEngine;
 using UnityEngine.UI;
  
 public class FlickerScript : $$anonymous$$onoBehaviour {
  public Image image;
  public float flickerTime = 0.1f;
  
  public void Start() {
       StartCoroutine("Flicker");
  }
  
  private IEnumerator Flicker() {
       while(true) {
            yield return new WaitForSeconds(flickerTime) ;
            image.enabled = !image.enabled;
       }
  }
 }

You add that script to any gameobject, drag any gameobject which has an UI image component which in turn has a black texture into the image slot, and hit play.

I strongly suggest doing some basic Unity tutorials first, though.
