Error in C

lazer21 · October 4, 2023, 1:28pm

I have this strange error in C. What can it be?

DanM · October 5, 2023, 7:31am

Do you have the workspace open? Did you do Tools > Refresh VS Code Project after creating the class?

lazer21 · October 5, 2023, 8:43am

No I didn’t. Whats this and where is it?

DanM · October 5, 2023, 8:58am

In Unreal

lazer21 · October 5, 2023, 9:09am

No result. But I’ve noticed these messages in vscode. By the way Im on mac

lazer21 · October 5, 2023, 9:22am

maybe I supposed to use Xcode? But if so, the lecturer messed up at this point. Since paying attention on Mac by telling how to download, he forgot to assist people on Mac to how to connect the project with Xcode

DanM · October 5, 2023, 10:21am

You only need to install Xcode to install the compiler, VS Code can be used on macOS with Unreal.

What does More Info tell you from the bottom prompt? You can probably ignore the first one as that is for debugging specifically.

lazer21 · October 5, 2023, 10:35am

I downloaded something from their website and nothing particular has changed

lazer21 · October 5, 2023, 10:41am

one my friend says that it can be circular dependency

DanM · October 5, 2023, 10:44am

I’m a little confused, clicking “More Info” in the screenshot made you download something?

I don’t see how that would have anything to do the dialogue boxes you have.

lazer21 · October 5, 2023, 11:15am

yea, something like ‘download the most suitable’ something. It was vscode 3 for some reason, but I didn’t notice that anything changed

lazer21 · October 5, 2023, 11:20am

anyway, do you have any idea about what can it be? I’m kinda furious that I can’t keep going for that long

DanM · October 5, 2023, 1:05pm

Could you show the problems window?

You have misspelled UPROPERTY

Also note this wouldn’t have anything to do with IntelliSense error in your original post.

Oh yeah, I see, but look what I get after compilation now

I just noticed that there is an error with typing f in the end of the float number. what a heck? I thought it is literate to do that or its only in c#?

DanM · October 6, 2023, 8:52am

There needs to be a . between the 0 and f. 0 is the start of an octal number which is what the error is talking about i.e. 010 should be 8

lazer21 · October 6, 2023, 8:53am

it is done now, all good. you helped me with uproperty, thank you!
