In the 19th lecture of “Developing 3D games with C# and Unity,” I did the same code written by the instructor, but I don’t think it’s possible in my Unity game. I think it’s because what’s shown in the image is not installed. Really? How do I solve this problem?
What error are you receiving?
Hi Su-Hyun,
Lines 1 and 2 refer to available namespaces that you have. However, they are darker than UnityEngine because you do not use anything from those namespaces in your code. Feel free to remove those two lines.
How do you know that the collision method does not work? Are the messages enabled in your console?

Do both objects have colliders?

Hey there is no “installation problem”: the first two using are greyed liked that because you’re not using them. You can even delete these first two lines and it won’t impact your code.
Issue is probably with your GameObject not having colliders in the scene editor…
