    I just started with Unity a few weeks ago. This probably has a very simple solution, but I cannot find an answer I could understand on the web. I want to fade out an object. The answers I found so far mentions about shaders and alpha channels, but I don't understand what it means. Help is appreciated!

    A sprite or a mesh? You can face both via alpha tweening. Scripting is slightly different though.

    Yeah, I meant in script. And just a sprite/object.

    Simple code. Use the first line as a variable and then the second in some sort of controlled environment such as an if statement inside a the Update loop.

    Code (csharp):
    1. SpriteRenderer sprRenderer = GetComponent<SpriteRenderer>();
    2. spriteRenderer.color = Color.Lerp(spriteRenderer.color, Color.clear, 3f * Time.deltaTime);
    Just a simple base. Don't use this code exactly as it won't get what you are looking for. Modify it a bit to make it fade in both ways. Maybe optimize somehow by only allowing the color to shift under certain conditions. Obviously only use GetComponent once in your Awake function.
