Hi there,
Recently I caused a crash with a delegate’s stack.
The following code has one safe guard, it checks if there is a typo in the function provided to BindUFunction.
Q: Is there a way to not only test if a bind found a function, but also if the signature is correct?
I am asking since execution of the delegate can cause a crash of the editor after a call of a bound function with a wrong signature, for example if it has a return value and the delegate’s signature doesn’t.
FTestIfHitByClickDelegate Delegate;
Delegate.BindUFunction(this, "SingleClick_TestIfHitByClick");
// Added this as a first guard
if (!Delegate.IsBound())
{
UE_LOG(LogTemp, Warning, TEXT("EnableSingleClickFunctions - Delegate not bound!"));
}
