Question by Faiz_Abdullah · Feb 20, 2020 at 12:32 PM · c#coroutineienumerator

Make a laser flickering.

Is this a good way to do it? I just set the laser on and off less than 100. I mean it is working, but it will stop once it reach 100. So yeah..

 void Start()
 {
     StartCoroutine(LaserFlickering());
 }
 
 IEnumerator LaserFlickering()
 {
     while (laserOnOff < 100)
     {
         yield return new WaitForSeconds(2);
         laser.SetActive(false);
         yield return new WaitForSeconds(2);
         laser.SetActive(true);
         laserOnOff += 1;
     }
 }

}

You could use a delay and a toggle for the activation

Something like this should do

 if (m_Delay < m_MaxDelay)
         {
             m_Delay += Time.deltaTime;
         }
 
         else
         {
             m_Delay = 0;
             m_Object.SetActive(!m_Object.activeSelf); //Toggles activation
         }

can you help me with a little bit more? I'm trying to make player health lose whenever player collide with the laser. This is my code:

public class Flickering : $$anonymous$$onoBehaviour { public GameObject laser; public float delay; public float maxDelay;

 void Update()
 {
     if (delay < maxDelay)
     {
         delay += Time.deltaTime;
     }

     else
     {
         delay = 0;
         laser.SetActive(!laser.activeSelf);
     }
 }

 public void OnTriggerEnter2D(Collider2D col)
 {
     HealthControl.health -= 1;
 }

}
