Sudden compilation errors

Development Programming & Scripting C++
1

Hello

My project was running fine. I opened the editor through VS2013 using Debug>Start New Instance. In the content browser I added a C++ Level Class called MyLevel. I closed the editor and reloaded the project as prompted and now I cannot build.

I have tried removing the level class and cleaning and resetting and other random stuff. I have tried removing substance and also putting it in my project plugins folder.

Any thoughts?

These are my errors:

Which Engine version are u using and is it the installer or source version.

U can try right click your project and choose “select Engine version” and “generate visual studio solution”

It seems the paths to the SDK are incorrect somehow

I’m running from source and I tried rebuilding the project files. I also tried to rebuild the engine but I’m getting pclaunch.rc.res is corrupt errors for that now. What happened to everything?!

This isn’t happening on the other projects and I am using a different engine install for them. I’m going to try and change the engine to a non source one.

I got it to work. I think I wasn’t deleting my Binaries and Source Files and Intermediate folder at the same time so the level class had some reference and for some reason it was breaking everything else. Very odd, I need more level class knowledge.
