Unreal becomes "not responding" always after building?

I think this also comes with the question I had on why unreal is so slow.
I was following the tutorial about programming c++ on unreal website(the pawn). Everytime I tried to build and run the editor I always get “not responding” on my task manager. Like really I have to force close it.

Anyone had this before?

EDIT: Yup I keep having this issue now. If Ive waited for too long it will just say “unreal engine stops working”

This happens whenever I try to remove some part of code to see what happens. I wonder why. It doesnt show any errors at build time at all. But why does it keeps hanging. That is so annoying.

Okay so everytime I add a component on editor and change its code on VS, unreal stops responding. I have no idea why it affects the editor itself. My build doesnt show any errors at all.

This is the error shown by the editor when it stops working

Perhaps you’ve created a pointer and tried to access it without initializing. A common example would be:

.h
UStaticMeshComponent* StaticMesh;

.cpp
(in constructor)
StaticMesh->SetActorLocation(…);

In the above example you would need to first call StaticMesh = CreateDefaultSubobject<UStaticMeshComponent>(“Static Mesh”);

So in short I recommend double checking your pointers.

Hi, Thanks for the answer. I actually check the pointer. and it was in fact being use on other function that would be called every frame I think. I remove the definition on the constructor but I cant believe that VS cant detect that. I should be better be carefull about pointer. Nevertheless shouldnt that be that VS will show some errors or the editor show an error message instead of becoming unresponsive?

Hello ,

I would suggest surrounding anything that refers to these pointers with:



if(pointer)
{
...
}
else
{
*print string here saying that pointer is null*
}

This will avoid problems with referencing a null pointer, as it will fail the if statement if the pointer is null.
