Blueprint Q key assignment shuts down Engine

LoN · October 15, 2014, 7:44pm

In My Character BT I press right click and then I press the “q” key to assign something, if I press enter node gets created end everything is fine but if I left click the “q” that i have typed (Instead of pressing enter) engines crushes and shuts down.

UE 4.5

This is error that i get when engine shuts down.

Assertion failed: StructPtrs.Num() != 0 [File:D:\BuildFarm\buildmachine_++depot+UE4-Releases+4.5\Engine\Source\Editor\DetailCustomizations\Private\KeyStructCustomization.cpp] [Line: 63]

Hey LoN,

I wasn’t able to reproduce this behavior. When you click Q you typed, do you mean you clicked Q Input inside menu after typing Q? Does this happen with any other inputs, or just Q? Have you attempted this in a new project, or does this only happen in your current project?

Please and attach crash log and dump file for your project after it crashes. You can read more about where to find that information here:

anonymous_user_33800a51 · October 21, 2014, 7:53pm

Hi LoN,

We haven’t heard back from you in a few days, so I am marking this post as resolved for tracking purposes. If you are still experiencing this crash, please provide information and logs requested above and we will continue investigating. Thanks!

LoN · October 25, 2014, 12:22pm

Sorry for late reply.

Now if i press left click the “Q” input gets created normaly but if i press “Enter” engine crashes.

It seems to happen both ways for some reason. It’s either this or other way around (Left click Or Enter)

This happens in every BP Graph i open and only in one project.

I couldn’t find the .log as there was nothing in directory specified but i could get my dump files.

Here are files: [link text][1]

And here is a picture of what i mean by “Q” input:

anonymous_user_33800a51 · October 31, 2014, 8:34pm

Hey LoN,

I discussed this with developers and they are aware of issue (UE-763 and UE-4443). There may be an additional cause for this bug and I will keep an eye on all of this. Once there’s an update, I will let you know. Thank you for your report!

LoN · November 1, 2014, 12:39pm

Thank you

WoefulMacabre · June 7, 2016, 12:57pm

Apologies for massive thread-necro I’m committing presently, but no “update” was ever posted here, so was this ever fixed and committed into a later engine?

assertion crashes relating purely to this issue are as present as ever in ARK’s modified 4.5.1 engine/editor and causing numerous headaches for myself as a modder and many others. If a fix was implemented, could I get commit to pass on to Developers(Wildcard)?

Thanks.

Sean_L · June 9, 2016, 2:00pm

Hello,

I’ll mark this topic as resolved, and move over to your new post to take a look at issue you’re having.

LoN · June 9, 2016, 2:13pm

I have no idea if it was fixed in 4.5 since I don’t use it anymore. I have never run into this problem again in latest versions.
