Updated my project from UE 4.7 to 4.8 and I am facing issues listed below.

A).Player character mostly won’t trigger on landed event.

After a jump my player character does get blocked by floor but won’t trigger ‘on landed’ event.(my floor is paper2d sprites having collision )

B). AI stopped moving

I have a simple AI controller that uses Event tick → Move to Actor. Both walking AI and Flying AI don’t move anymore.

C). All particle effects are messed and does not appear correctly.

To match effect same as 4.7 I need to increase Spawn rate by 4x.

D).Load Stream Level time has increase a lot.

Loading time to load a new level has increased to 4x/5x than what it was in 4.7.

Hi ,

Could you please create additional reports in Bug section for issues B, C, and D? This will allow us to better keep track and work with you on these issues.

As for issue A, I am investigating that now and will post back here with questions/comments soon.

I tested this by:

  • Creating a 4.7.6 ‘2DSideScroller’ template project

  • Added a ‘OnLanded’ event to ‘2DSideScrollerCharacter’ that Prints text on landing

  • Converted project to 4.8

However I couldn’t reproduce your results. on landed event fired and floor collision worked correctly.

Could you post a small test project that contains issues?

Sorry for late reply, I will do needful soon.
Adding info for issue A, my character is a 3d character having default Capsule component with collision set as Pawn.
Issue A occur 60% of time and not always.

I have inboxed you link to my project which includes all issues.

I sent you a private message as well, but I can’t access download that you sent me. You should be able to get a link that allows access.

I downloaded your test project and it opened in 4.8. While jumping around, On Landed Event prints almost every time. only time it doesn’t print is sometimes jumping on or near overlapping sections of a platform.

Is this what you are seeing as well or is On Landed Event not triggering at all?

Yes this is what i am experiencing. On landing Event do triggers but many times it won’t(jumping on or near overlapping sections of a platform), but it works fine on 4.7.6 and earlier versions.

Hi ,

I’m not exactly sure what root cause is but I believe I know how to fix issue. I noticed if player capsule is equal in size (yours is Half Height = 55 / Radius = 55) then sometimes OnLand event will not fire and player is caught in some sort of sliding loop until they reach an uneven surface.

To fix issue, change capsule to Half Height = 56 / Radius = 55.

Like I said, I’m not exactly sure what root cause is and I can’t seem to reproduce it outside of your projects. Which makes me think it’s maybe a combination of various things.

Let me know if it works for you.

Cheers,

TJ

Yes, changing capsule dimensions did worked for my character. But still rest of issues are affecting my development on 4.8

Hi ,

TJ is going to be out of office for a bit, and I’ll be looking into this for now. Could you please PM me link to project as well so I can test these issues?

I would also like to separate issues you’ve described into separate posts so we can get appropriate people to look into them. If you would, please create a new Bug Report post for each of issues you listed (except for first one, which we will address here) and post a link here as a response so I can track them properly. Thank you!
