Hello Rick,

I just wondering what is the function of ‘as GameObject’? Cuz I tried not to use it and it still works. Thank you

Usually we “cast” something using “as GameObject” so that we can then later use that game object to do something else with. If you want to dig deeper into this, google around for “casting” in Unity and C#.

Thank you for the answer Rick. Actually I’ve been searched it on Google before you answer the question lol and it took me hard to find the keyword, but I finally knew it as a “Cast”. There are a lot of type of Cast in C#, are they all used in Unity?

I cant comment if they are all used in Unity, but I do know that casting is a pretty common approach.
