Strobe light like airplanes do

Unity Engine
1

Hi, is it possible to make a script for a light to make it look like an aircraft blinking light?

thank you

Yeah, look up WaitForSeconds in a coroutine, and use a bool to command the lights

hmmm, i don’t know how to do that, i pretty young at unity scripting, can you help me please?

thank you

A script would definitely work but why not just a simple looping animation on your light object? Even simpler imo.

i have this simple code and it works:

function Start() {
 
flickerLight();

}
 
function Update () {
}
 
function flickerLight() {
 
for (var x = 1; x > 0; x++) {
    
yield WaitForSeconds(2);
 
 
gameObject.light.intensity += 10; 
 
yield WaitForSeconds(0.02); 
 
 
gameObject.light.intensity = 0;

}
    
}

but i want the light to be off when i press play and then starts to blink

Oop, somebody beat me to it. Oh well, here’s another option that allows for falloff time.

using UnityEngine;
using System.Collections;

public class BlinkingLight : MonoBehaviour {
	
	public float blinkSpeed = 1;
	
	float timer = 0;
	
	float mIntensity;
	
	//Keep this in the 0-1 range in your inspector as the timer only goes from 0-1
	public AnimationCurve lightCurve;
	
	void Start () {
		mIntensity = light.intensity;
	}
	
	void Update () {
		timer += Time.deltaTime * blinkSpeed;
		if(timer > 1)
			timer = 0;
		
		light.intensity = lightCurve.Evaluate(timer);
	}
}

Light _light;
public float onTime = 2;
public float offTime = 0.5f;

void Start()
{
  _light = transform.light;
  Toggle();
}

void Toggle()
{
  if(!_light) return;
  
  _light.enabled = !_light.enabled;

  if(_light.enabled)
    Invoke("Toggle", onTime);
  else Invoke("Toggle", offTime);
 
}
