Animate fog color smoothly

Hello, I would like to animate the Render Settings fog color, ideally smoothly over a period of 5 seconds. I'd like it to happen automatically when I enter Play mode. I'm very new to scripting, so I'd appreciate any help directed at my beginner level. Also, I understand that you can attach scripts to objects in the scene, but I don't know where you would attach a script that was affecting the Render Settings.

PS I did find this http://forum.unity3d.com/threads/animate-fog-color.111353/ but all of the links point to a dead unifycommunity website.

Thanks in advance and apologies for my beginner-ness.

 

The concepts you will need for this are:

Color.Lerp
http://docs.unity3d.com/ScriptReference/Color.Lerp.html

This will allow you to adjust color over time. The example used transitions over one second - multiplying the time factor by 0.2f will make the transition occur over 5 seconds.

RenderSettings.fogColor
http://docs.unity3d.com/ScriptReference/RenderSettings-fogColor.html

This lets you change the fog color in your scripts. Combining this with Color.Lerp will tranistion FogColor over time.

Finally, where do you actually put this code, since you don't see an object that directly correlates with RenderSettings?
You can always create an Empty Gameobject to attach scripts such as this one too. Any object can access scene wide settings such as RenderSettings.

 

Thank you for the reply! I will experiment with these references.
