Posted - Apr 13 2022 : 10:04:36 AM Hi! Using UE4 with Visual Studio, it looks like "auto" keywords aren't being recognized in things like for loops, e.g.:
TArray<Activity*> Activities;
for (auto activity : Activities)
{
if (activity->)
{
;
}
}
i.e. not getting any suggestion after the "->"
I only recently started using "auto" and was wondering if this is expected or an issue. Thanks!

Posted - Apr 15 2022 : 09:39:23 AM I have found a work around, but it does require editing the Unreal Engine TArray header file, so if you want to try this you will need to make the same edit after updating to a new version of UE. I edited the file:
it is wrapped in the #ifdef to make sure the compiler removes it, but VA will still parse it. You need to add this near the top of the class, before the actual declaration of begin(), I put it in after line 314, and then triggered a VA symbol database rebuild with:
VA Options -> Performance -> Rebuild symbol databases
so VA would see the edit, which requires an IDE restart to take effect.

Posted - Apr 14 2022 : 06:20:52 AM IDE intellisense vs VA intellisense is an option in our options dialog since some situations work better with one, and other situations work better with the other. It's not something we can easily predict.
Generally VA does a better job with Unreal Engine than the IDE, and the IDE intellisense parser can be a significant overhead, given the size of Unreal Engine, which is why quite a few of our users report disabling IDE intellisense with Visual Studio. In this situation IDE intellisense understands the loop across TArray while VA doesn't, so enabling IDE intellisense will help, if you don't mind the performance impact.
I hope this makes sense and helps to explain the situation a bit better.

I will see if I can find a work around, to try and get VA to understand TArray a bit better. For now, you might find setting:
VA Options -> Enhanced Listboxes -> Source of C/C++ content: Default Intellisense
assuming you have not disabled the IDE intellisense parser, which quite a few of our users do when working with Unreal Engine.
