Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Packaged game TileMap collisions not working when "Make Tile Map Editable"


We have a project where we modify the tiles of a Tile Map inside a Paper Tile Map Component at runtime (only at level start).

As you can see in the image we instantiate the tilemap and we rebuild the collision to be able to modify it.

alt text

ONLY making this operation in PIE ALL the collisions work OK. BUT if we execute the packaged windows game, there are collisions that doesn't work (for example an slope (three collision vertex))

We are targetting Windows, not mobiles

In PIE ALL the collisions work. BUT when we package the game and execute it, some tile collisions doesn't work!

Tested on 4.18.0



This is a showstopper for us :s, is this a known issue? Or are we doing something wrong? Thank you :)

I was unable to reproduce the issue you are experiencing. I have a couple of questions to help narrow down the issue you are experiencing.

  1. Can you reproduce this issue in a clean project?

  2. If so could you provide a detailed list of steps so that I can reproduce this issue on our end?

  3. What part of the collision does not work in the packaged build?

Hello Thomas!

I added a video (attachment bug-1.zip) showing the bug on a clean project.

Thank you!!!

avatar image Roig Nov 29 '17 at 02:42 PM

Hello again Thomas, did you see the video? I just want to confirm that this is a bug and if it will be fixed or we should workaround it.


avatar image Roig Nov 24 '17 at 08:53 AM

I tried with 4.18.1 with the same results..

You say that it may not be fixed anytime soon, is there any workaround to this then? Because this makes Tilemaps pretty much unusable for any dynamic maps.

avatar image Roig Jan 15 '18 at 10:43 AM

Yes.. without it, dynamic Tilemaps are useless.. don't know why Epic doesn't set critical priority to this.. I suppose it's because the Paper2D is not in their roadmap.. Other engines have more love to their 2D parts..

Hey Roig, I'm sorry to post here on this post, but have you solved the [Yellow] Paper2D Tilemap problem or did you just live with it? I am wondering if you have a solution that I am not aware of. I am referring too: https://answers.unrealengine.com/questions/715782/paper-2d-yellow-tinted-textures-in-tilemap-viewpor.html?childToView=746738#answer-746738

avatar image Roig Jan 15 '18 at 04:38 PM

We just live with it.. till now that we will try to use your solution.. thank you!! And again, don't know why those simple issues are not addressed quickly in the Paper2D plugin.

+1 Epic should fix this.

In my case I cannot get collision to rebuild for Polygons or Circles. I have wasted a lot of time trying to get this to work.

avatar image Roig May 04 '18 at 03:11 PM

Sorry but, sarcasm? xDD The bug is not fixed..

avatar image jeremythuff May 31 '18 at 07:12 PM

Yeah, sorry, that was worded ambiguously, I only meant +1 for the idea that Epic SHOULD fix it, not that it had been fixed. Changed it.
