Actor Class doesn't update

actual_1 · March 22, 2014, 9:32pm

Not sure if I should’ve posted this on “getting started” or not. But here goes.

First time delving into C++. I followed the “programming quick start” and was successfully able to finish the “hello world” project. Then, just for the hell of it, I went back to the class and changed the values to see it updated in the editor, but it wouldn’t update. I tried building again, closed and opened up the editor, etc. It only shows the values I initially assigned to the variables. I even opened up the code through class viewer and Scene outlines, and it shows the updated values in the code, but the same values when running the game. Any ideas what I’m doing wrong? Thanks!

EDIT:

Thanks!

For some reason I was still on development, even though I remember following the tutorial and changing it… I changed it to development editor and now I’m getting lots of errors in visual studio, and I can’t compile in editor. here are the errors:

Also, just fyi, for 64bit, in the solutions platforms, I had to click on “configuration manage” and choose x64 there. Other than that I don’t see the actual 64bit there, only “windows”. this is 2013 express that was linked in the tutorial.

#Development Editor

Are you building for Development Editor, Win64 ?

#Expanding VS Window

“Also, just fyi, for 64bit, in the solutions platforms, I had to click on “configuration manage” and choose x64 there. Other than that I don’t see the actual 64bit there, only “windows”. this is 2013 express that was linked in the tutorial.”

there are detailed instructions on Epic’s Git Hub and even in the video linked on Git Hub explaining how to expand the build configuration bar

I just go to build->configuration personally

PS: for the rest of your errors, I am not sure, try logging off and back on and then post any updates on exactly what error you’re getting, it looks like it is not finding your project .dll, which might be your directory structure or your build cs or something! I dont know

Yep. I went through that tutorial and expanded the build configuration bar. It only has “windows” in solutions platforms. So I went to configuration manager and changed it to 64 there. odd.

Also, I don’t know how I did it, but I fixed the compile error and everything seems to work fine, although I’m still getting “Unable to delete old hot reload file:” errors, but no build fails

did you hid the non essential errors?

You should look through the git hub tutorial on formatting VS

you have to add the additional window to show 64

and you should be ignoring all non-essential errors

#Tutorial Link

For the rest check out the git hub video!

#Video

He shows how to add the Win64 bar toward the end

PS: if this resolves all your questions please check mark this thread so Epic knows all is well

Yep, watched that video about 4 times now and did those things exactly, and checked and rechecked them

-clicked “standard toolbar options”>add/remove>solution platform. open dropdown for solution platform and I see windows…go to configuration manager and set 64x there by default.
-went to tools>options>projects and solutions>unchecked “always show error list if build finishes with error”

still getting the “Unable to delete old hot reload file:” when compiling, but with successful builds now, so maybe I should ignore it?

btw, the new errors are multiple lines of this, each associated with a different dll file:

1>  Deleting old hot reload file: "C:\Users\xxuser\Documents\Unreal Projects\myProject\Binaries\Win64\UE4Editor-myProject-1747.dll".
