UE4 Crashes Every Time I Open it

Development Programming & Scripting
1

My project crashes every time I open it. I have tried to replace autosave files with suspected problem files but that hasn’t worked. It all happened when I compiled some new code in VS and it compiled successfully, so I go to compile from the UE4 editor and a minute later the engine crashes. When I attempt to launch my project the engine crash again.

Here is the message I get:

You do not have any debugging symbols required to display the callstack for this crash.

That doesn't really help I guess.
This is the message in the log file.

Hey -

The error says that the incorrect object initializer is being used which leads me to believe there may be an issue with a constructor somewhere. Can you try commenting out the code that was added prior to the crash and then compile from inside Visual Studio. If you are still unable to open the project please provide the code that was added, it is possible that though the code compiled correctly it is interacting with the editor in a strange way.

3

I tried commenting the code and it didn’t fix anything. So I then uncommented everything thing and start to us Visual Studios debugger to solve the problem. Now I get a completely new error. VS keeps saying the problem comes from code I wrote a long time a ago.

This is the code.

//Creating Mesh component
	MeshComp = CreateDefaultSubobject<UStaticMeshComponent>(TEXT("MeshComp"));
4

Are you still attempting to open the project or are you trying to package the project? The new log file below mentions cooked data, which is why I ask. Is this the code that you added recently or the code that Visual Studio is now saying is causing the compile error? Can you provide the exact error that Visual Studio is giving you?

5

I get no error when I compile, I only get an error when I attempt to build using the Start Debug Option in Visual Studio and when I launch the project. The error below is from the UE Log file for the project, It is the new error I am getting.

6

Sorry I am not explaining what is going on very well.

7

Okay then. That leads me back to believe that there is an issue with your constructor that, while it compiles successfully, is causing issues with the editor. Can you post the full constructor for the class(es) you were working in prior to the project failing to open.

8

Hey -

Can you add the ADrunkSimulatorCharacter::ADrunkSimulatorCharacter() and AItem::AItem() functions as well.

I am attempting to have the player raycast once they have entered a trigger. This is the code for that.

	FCollisionQueryParams* TraceParams = new FCollisionQueryParams();

	if (GetWorld()->LineTraceSingleByChannel(*HitResult, StartTrace, EndTrace, ECC_Visibility, *TraceParams))
	{

Looking at the header files provided, I cannot see a definite cause of the “Using incorrect object initializer.” error you’re getting. If these are the only classes you worked on prior to the project failing to open I’m not sure what could be causing this without looking at the code directly. If possible, could you provide a copy of the project to test? This can be done privately by uploading the project to google drive / dropbox and then sending me a PM on the forums with a download link.

Hey -

After looking at the code for the project, I found that in IntObject.cpp at line 22 you have MeshComponent->CreateDefaultSubobject. If you edit this line to MeshComponent = CreateDefaultSubobject with the equal rather than arrow operator, the project will compile and open successfully. In this case you are creating the StaticMeshComponent and then assigning it to the MeshComponent variable.

Cheers

Thank you so much can’t believe I didn’t see that before. I still have one problem thought… The project still crashes with the same error when I try and launch it. I should be using Build->Build Solution to build the project correct?

Build Solution should build everything that has not been built before or has changed since the last build. Another option you can use would be to select the project itself in the Solution Explorer and select Build from the right-click menu. This will build only the project module and its required files. This is the option I used when building the project on my end and was able to open it after the compile completed.

Even deleting IntObject.cpp and IntObject.h in both VS and the source folder doesn’t fix the issue. I don’t understand why you can launch successfully but I cannot. There must an issue some where else too. But I have been looking for hours and I can’t find anything.

It still doesn’t work. I tried replacing all the project files for the heck of it but still nothing. Well I’ll keep trying to figure it out. Thanks for the help

If you’ve deleted files from the source folder, you will need to right click the .uproject and select “Generate Visual Studio project files” to ensure that the .sln is updated with the removed files. If you still have a copy of the removed files, the only other change I can think of would be to move the public: line in IntObject.h above the UPROPERTY() line for your MeshComponent.
