I’m 99% sure I followed the instructions correctly but here’s the error log

Building SimpleShooterEditor…

this float has red squiggles in shootercharacter.h

UPROPERTY(VisibleAnywhere)
float Health;

which means red squiggles under “Health” in shootercharacter.cpp

Super::BeginPlay();

Health = MaxHealth;

also attached an image for the other 2 errors

and last thing, at 8:02, the instructor uses a keyboard command to “build” without reminding us what keys he’s pressing. I picked back up after a week of vacation and didn’t remember the keys, so i did a couple of ctrl+shift+? before finding it. the build didn’t work anyway but in future courses, saying the shortcuts every time should be a thing. or at least adding them visually overlayed in the video.

idk how to copypaste bigger chunks of code neatly but can provide more screenshots if needed. thank you so much for your help

#2

Could you post the full header?

You can surround the code with 3 backticks

```
code goes here
```

Or highlight the text and press the </> button.

That would be Ctrl + Shift + B > ProjectNameEditor Development Build

This should end in a semicolon not a comma.

#5

ok I fixed that but now I can’t open the unreal project again
error2
neither option works.
did making that change without unreal open have negative consequences?
I tried reverting to the comma and opening the project again but got hit with the same failure.

#6

Then you might have more compilation errors. What’s the output after fixing that mistake?

#7

I think I fixed it. I had a semicolon on the end of line 51 of ShooterCharacter.cpp.

float AShooterCharacter::TakeDamage(float DamageAmount, struct FDamageEvent const &DamageEvent, class AController *EventInstigator, AActor *DamageCauser);

I deleted it and everything seems to be in order now.

Thank you so much for being active here, I really appreciate your help
