Hi! I am trying to just find an int32 in a Tarray and its crashing the code.

UFUNCTION(BlueprintCallable)
	int32 ittemsAmmount()
	{
		return UKismetArrayLibrary::Array_Find(numbers,45);
	}

tried other UkismetArrayLibrary functions like Array_Lenght with same results.

The array is not empty (perhaps if it where should return -1 instead crashing, but the main problem is that even it is a valir array the program crashes.

the error:

this calls my attention…why D??? I have a D drive but not using it and D:/Build doesn’t exists.

That’s not going to work. Yu shouldn’t really ever need to use any functions from the Kismet libraries, these functions in particular use CustomThunk bodies which are special Blueprint code.

Just use the built-in functions within the array (i.e, MyArray.Find(value). It will return a pointer to a value IF it exists.
