2D Experimental Preview Release 4 Breaking Changes

2D
1

Hello, Thank you for all the work that you guys have done with the 2D Experimental Preview so far.

But I just updated a project from Experimental Preview Release 3 to Experimental Preview Release 4. I backed up the project first. But in the new version my tilemaps, tilesets, and tile palettes are all completely broken. I think the reason might because you changed the component ids, and names. Also in the scene the tilemap component has been replaced by a video player component, and I think the tile grid has been replaced by a sprite mask.

I was wondering if there is an easy way that I could fix this without remaking the tilemaps from scratch. Because this would be a lot of work.

Thanks alot,
Chris Johnson

One of the guys made some Python scripts to help “upgrade” the project files.

Update guide for serialization

  • Before updating to this preview, change the asset serialization method for your projects to Force Text and save your project. - Edit/EditorSettings/Asset Serialization
  • Make a backup of your project
  • Download the attached PythonScripts.zip
  • Install Python
  • Run classtm.py in your project’s assets folder to update the Ids for your Tilemap components
  • Run classtile.py in your project’s assets or tiles folder to update your Tile assets

I have not tried it myself. Hopefully this helps in some way.

Thanks, I’ll give it a try and tell you if it worked or not.

That python script fixed the tilemap, but in the editor palette tab one of my tile palettes is missing, and the other one doesn’t work. Here is an error that I get in editor.

GridPalette subasset not found from: Assets/Tile Palettes/Yellow.prefab
UnityEngine.GUIUtility: ProcessEvent(Int32, IntPtr)

I also keep getting this error when I click on the drop down menu where you can pick your tile palette in the editor.

Internal: JobTempAlloc has allocations that are more than 4 frames old - this is not allowed and likely a leak

I sort of fixed the tile palettes now. It looks like the tile palette prefabs needed this piece of code in them.

— !u!114 &114230327204373143
MonoBehaviour:
m_ObjectHideFlags: 0
m_PrefabParentObject: {fileID: 0}
m_PrefabInternal: {fileID: 0}
m_GameObject: {fileID: 0}
m_Enabled: 1
m_EditorHideFlags: 1
m_Script: {fileID: 12395, guid: 0000000000000000e000000000000000, type: 0}
m_Name: Palette Settings
m_EditorClassIdentifier:
cellSizing: 0

Also I think that this id should be different for every tile palette prefab “114230327204373143”

But I still keep getting this warning all the time in the editor.

Internal: JobTempAlloc has allocations that are more than 4 frames old - this is not allowed and likely a leak

Ok, I some how got rid of that Internal: JobTempAlloc warning now. I’m not really sure why it went away. All I did was change the Tilemap Renderer’s mode from individual to chunk, and saved the scene. It might of just been that the scene needed to be resaved I’m not sure. But it looks like everything is working now for the most part except a few minor bugs that should be easy to fix.

Thanks Johaness_Reuben for the help with that python script, hopefully there won’t be any more major issues.

Hi, I runned the two pys and they all got same error:

File “classtile.py”, line 8
if (str(file).endswith(“.asset”)):
^
TabError: inconsistent use of tabs and spaces in indentation

Maybe because I’m using python 3?

Yeah, if I remember correctly I think I had to use python 2.
