Increase Light Intensity in Coroutine

Questions & Answers
1

I am trying to increase a light to get a camera flash effect with a coroutine, but for some reason I cannot increment the light’s intensity. This is what I have so far:

  IEnumerator CameraFlash( tk2dAnimatedSprite sprite ){	
    		GameObject flare = GameObject.Find( "CameraFlare" );
    		flare.light.intensity = 0;
    		float steps = (float) (3 / 9);
    		while(flare.light.intensity < 3){
    			yield return null;
    			flare.light.intensity =  steps;
    			steps+=steps;
    		}
    }

enter code hereThe problem is with this line:

float steps = (float) (3 / 9);

You don’t cast your values to a float until after the integer division, so 3 / 9 will be 0 and your loop will never complete.

Change the line to :

float steps = 3.0f / 9.0f;
