UE4/5: C2440 error in Array.h prevents compiling

[irdc]

Hi. This is in UE5 but it seems this error in UE4.

I changed some variables in a USTRUCTURE in C++. One variable was renamed, one was reclassed and a few others were deleted. I compiled and got the usual GENERATED_USTRUCT_BODY error that required me to delete my binaries folder and recompile as outlined here:

GENERATED_BODY macro causes error "this declaration has no storage class or type specifier"

Hey guys, I’m fairly new to UE and am currently busy (or at least trying to) with the 3rd Person Power-Up Game with C++ video tutorial. Already in the third assignment, after creating my first class, I’m running into problems. First, I know that the tutorial has been made using ver. 4.2, but I downloaded the 4.7 source code to accomodate for that. But now, Visual Studio/Intellisense is underlining the GENERATED_BODY macro in red, telling me that “this declaration has no storage class or type sp…

This has worked before in the past and it worked again today. The only problem was that I am now getting the following error:

Error C2440 ‘initializing’: cannot convert from ‘T’ to ‘int’ … C:\Program Files\Epic Games\UE_5.0EA\Engine\Source\Runtime\Core\Public\Containers\Array.h 1973

As this is referencing the Engine, I am not sure what to do. I have gone back and changed a few variables, switched Solution Configurations and done a few other things, and this error still persists. I cannot compile by project nor can I load it in UE as it needs to build the project again but cannot.

Does anyone have any experience with this? I am thinking that it is associated with changing a TArray of FIntVectors to int32s. Any help is appreciated. Thanks

Was a user error. It did have to do with changing a TArray from holding int32s instead of an FIntvector. I had some other code buried that was adding a vector to the TArray but didn’t generate a compilation error. Don’t rely on just the error list; look in the Output as well.
