How do I handle errors in C++ for Unreal Engine?

In Unreal Engine, you can handle errors using try-catch blocks, assertions, and logging. Would you like examples?

Yes, please provide an example of using try-catch.

Sure! Here's a simple example:

try {
    // Code that may throw an exception
} catch (const std::exception& e) {
    UE_LOG(LogTemp, Error, TEXT("Error: %s"), *FString(e.what()));
}
``` This logs the error message to the output log.

What about using assertions?

Assertions can be used to catch errors during development. You can use check(condition) to ensure a condition is true. If it's false, the game will crash with an error message.

How can I log errors for later analysis?

You can use UE_LOG to log errors to the output log. For example:

UE_LOG(LogTemp, Error, TEXT("An error occurred: %s"), *FString(errorMessage));
``` This helps in tracking issues during development.
