[Paper2D] Collision on isometric mode

Development World Creation

Hey there,
I encountered a bug on 4.13.0 regarding Paper2D and the isometric view mode.
It renders the tiles correctly in the isometric mode, but the collision is not generated in isometric mode, but in the standard orthogonal mode.
A picture to visualize this:

1211×297 135 KB

Left hand side shows the Player Collision visualization, and the right hand side the standard view.
To compare, heres the map rendered in orthogonal mode:

869×458 8.75 KB

You can see how the collision is the same like the orthogonal one, so the bug is that the collision doesn’t generate after the viewmode.
Thanks for feedback!

Sorry for the misunderstanding, basicially, every tile which you can see there has a simple collision which fits the -shaped tile. So to the right you see how the map is designed with the isometric viewmode. The problem I encountered is that If I walk with my character on the tile map (as I said, the right one is how it looks in the level), I can walk on the air, and I fall through the left part of the tile map, so I visualized the collision in the viewport, and you can see that the collision doesn’t match with the tile geometry, but with the orthographic viewmode => The collision doesn’t change on isometric viewmode, but it should. I hope that was clear :slight_smile:

Hi ,

I am a little confused as to what you mean specifically. The viewport viewmode does not directly alter the collision of actors within the world. Are you making specific changes to the collision of your sprites and a change made within them is not taking effect? What steps can I take to reproduce this error on my end?

Do you have a sample project this is occurring in or specific steps I can take to recreate this on my end?

Yup, here!

Hi ,

I wanted to update here and let you know we are still looking into this error. I will post back here once I have an update.

Hey !UltimateLP,

Thanks for the clear and precise repro steps. I was able to confirm what you are reporting and have gone ahead and entered a bug report for the issue. You can track the issue following the link below on our public issues tracker.

Once the issue has been addressed by our engineers either myself or another staff member will return with an update.

Let me know if you have further questions or need additional assistance.

Thanks for catching that error. The two bugs were similar in number which is where I got the two mixed up, but I went ahead and updated the post so it reflects the correct bug I entered regarding this issue.

This is still marked as unresolved as you have discovered in your test example project. It is marked to be fixed for 4.18, but that could change due to resources and priorities.

Thanks for your patience and keep an eye on the issues tracker for updates or changes to this bug.

Cheers,

I realise this is an old post, however I’m experiencing this issue within UE 4.16.1.

It’s very simple to re-create.

  1. Create new project (I used third person template)
  2. Create a tilemap from any tilesheet with tiles that have collision
  3. Set the tilemap to Isometric and fill it with any tiles that have collision
  4. Run game and show blocking volumes in-game (‘show Collision’ in console)

You can see my results of this simple test hereibb.co/dNc97v

The bug you list in this answer is not the one that is associated with this post. I assume that the old bug ID has been rolled around in this case. Please look into this further as it has been a very long awaited outstanding bug.

Still not solved in 4.18 sadly!

22.02.2018 STILL NO COLLISION FOR ISOMETRIC MAPS

PLEASE PLEASE EPIC PLEASE FIX THIS!

We need more votes on the ticket.
