Noob Question, Should I Build UE4 from Github?

Community Community & Industry Discussion

Hi all, I have recently joined the UE4 community. And am checking out the programming aspect to UE4.

The first tutorial I have followed is “Intro To Programming”

And the first line of code I had the pleasure to copy paste produced 25 Red Errors in my Visual Studio.

UPPROPERTY(VisibleDefaultsOnly, Category = Powerup)
TSubobjectPtr<USphereComponent> TouchSphere;

This is not what “getting off on the right foot should feel like”. Have I set up my envirotnment improperly?
Should I actually erase the current EU4 installation and build it from github? That seems like a hassle, I just
want to write code :frowning:

When I scroll over the UPPROPERTY VS tells me “Error: explicit type missing(‘int’ assumed)”

When I try to build.

And btw, I am getting no intellisence help about the UPROPERTY() thingy.
and the tutorial itself didn’t explain anything code related.

Can you please paste the errors you got from VS here?

4

you are completely right.

5

OK, lets see what we can find…

First change UPPROPERTY to UPROPERTY and try compiling again.

6

Shall I interpret that as everything is working now, after fixing that little typo?

7

(head slap) how embarassing, I am unworthy. I even double checked for typos before posting here.

8

I don’t see how this question can benefit mankind by being stored in here. so I will erase it in an hour or two, thank you for the help

9

Hey, no problem! I’ve made millions of typos myself the last 40 years or so. It happens to all of us.

apparently I can’t erase questions with answers on them, its not that I am embrassed of this question or anything (I really dont care). I just dont think that anyone can ever benefit it by looking at it. So if you agree then remove your answer, but if you rather have extra points, then whatever.
