I'm new at coding and game developing uhm I have visual studio and unity 3d but when I open the script file I can't write codes, Let me show you with Image, as you can see visual studio won't verify the codes.

I wrote. What is wrong ? and another thing when I watch the education about unity programming, teacher opens a diffrent coding screen than mine. Like we're using same things I checked like 5 times but still Mine is opening with visual studio but teacher's coding screen opens with something else.,

I'm sorry maybe these kinda questions would be basic stuff but I don't know where else to ask. Thank you for reading so far.

I tried couple things from internet but still no result.

Also about the debug command uhm as you can see in the picture like uhm it won't verify the command I don't know why I tried writing something diffrent like "If Else" it verify them but not debug. Why ?alt text
