Unreal Engine 4.25.3 crushes when it is compiled and clicked play

Physics_Engineer · September 10, 2020, 4:09am

I am using VS CODE. I am studying Udemy lessons of UNREAL C++. at 45th lesson(making a “Bull Cow Game”), I did as they say and tried to make unreal print “Hİ THERE” by using VS CODE. But UNREAL crushed. Error:

How can I fix this?

I tried: adding in the terminal

cl BullCowCartridge.cpp/EHsc/Zi

Doing this gave this error:

C:\UnrealBullCow\BullCowGame-starter-kit\Source\BullCowGame>

Press F5 in the Terminal gave this error:

Terminal will be reused by tasks, press any key to close it.

What can I do?

SOLUTION

Assertion failed: Terminal [File:C:\UnrealBullCow\BullCowGame-starter-kit\Source\BullCowGame\Console\Cartridge.cpp] [Line: 12] [BullCowCartridge]: No Terminal found

That means you attached the component to an actor without a Terminal component or you removed the Terminal component already on the actor.

If you go into Console > Cartridge and change this on line 12

*GetName()

to

*GetOwner()->GetName()

The crash should tell you what actor is missing it.

One of the cows occurred as “terminal” in the “world outliner” tab, and one of the other cow has already had a Cartridge attached to it. After I deleted the terminal cow and delete the Cartridge from other cow, it worked!

Thank you for finding the solution! I made the mistake of adding the BullCowCartrige to the cow actor instead of the terminal actor, which caused it to crash like this.
