I have 2 tiles on my tilemap that i cannot remove/erase

See the attached image.
They're part of the "MainGround" tilemap in the hierarchy, I know this because they're using the same tilemap collision and they disappear when I hide the gameobject.
However I cannot erase them, I have tried everything.
Found one post saying I should try reimporting assets, I tried that but didn't work.
The only other thing I could think is causing it is the "Can change Z position" which is currently unchecked and at 0, and I can't remember if I adjusted that in the past or not.
It's really frustrating as I don't want to delete the tilemap and redo the level if possible.
Any help is greatly appreciated.

 

The delete tool in the tile palette will work only if you have selected the palette that was used to paint the tiles on the tilemap.

 

Yes I know, thanks though.
Have tried all the usual stuff.

 

would duplicating the tilemap do anything (trying to edit that) ?
next thing i'd probably try using script to clone tilemap or clear using script..

 

No luck with duplicating either, same problem.
I guess ill just use this as an excuse to get some rule tiles finally sorted out so I can quickly repaint the level.
Thanks for the replies guys.

 

Are you sure you have done it properly, that you had the right palette selected in the tilemap palette?

https://docs.unity3d.com/Manual/Tilemap-Painting.html#Eraser

Or, maybe you had the right palette selected but you were trying to delete the tile on a tilemap that was not the tilemap on which the tile was painted.

 

Yes have tried selecting all pallets and each tilemap individually, the only palette with that tile on is the Main one I use.

 

What version of Unity are you using? You should report a bug.

 

Just updated yesterday to latest 2019.3.0f6 , although i honestly can't remember if i had this problem on the last version too because it's been there a while. I'll report it for both after i eat but have no way to reproduce at this time.

 

I haven't read every post. Did someome suggested the following:

1. select the tilemap,
2. in the palete select the erase tool,
3. press the Ctrl key and drag a rectangle around the tiles to be deleted,
4. left click do erase the tiles.

Press Ctrl + left click to get rid of the selection rectangle afterwards.

 

Yep, tried that too, tried selecting, moving, etc but it doesn't budge
If I move the entire tilemap with the selection tool it still doesn't move however if I move the entire tilemap with just the standard engine/object transform tools it does move.
It would honestly take me less than 5 mins to redo it with rule tiles, but would be nice to understand what's causing it still. I'll get it reported as a bug.

 

Could you post your project somewhere? I'm curious, I'd like to take a look at it, if you don't mind, of course.

 

Ah sorry would have loved to but i already corrected the issue now by just deleting the tilemap and re-doing it all.

 

That's an interesting question; I didn't know we could paint tiles on a tilemap at a z position that would be not the tilemap z position.

 

Well well, thank you for the tip. I'm going to do that in my game, just to make sure nothing of the kind happened on my tilemaps.

 

Thanks for the reply, If it happens again ill look at that. I tried uploading it as a bug but the upload progress got stuck on 65% for a good hour+ and it shouldn't have been related to my internet speed so i had no choice but to cancel it.
But hopefully, by the sounds of this reply, it wasn't a bug after all and maybe just a mistake i made with the Z positions.

Thanks

 

It's possible to remove the tiles with the eraser if you know what the z value of the tile is. Is there a way to know what the specific z value is for the tile?

 

if you change your scene view to 3d you will see the tiles sticking out if you rotate the camera

 

Hi, we're having the same or at least a similar problem in a game my team and I making for university. Of course the Problem occured only days before the deadline. Some tiles on different tilemaps are not erasable and they get randered weirdly in the game. compare:

Would be great if a solution could be found. We already started repainting the whole map, but thats a whole bunch of work.

 

Just figured it out... it was the z pane problem! Thank you

 

Click edit in tile palette!

 

Very old post, but in case someone has this error in the future as well: my problem was that I had a prefab brush selected, when i changed it back to default brush it did remove the tiles from my map

 

i found the reason why some tile do not get deleted. if you move them then you are not able to delete it anymore. you need to select the old position. i think this is a bug.

unity 2021.3.1

 

Unity 2020.3.41f1 Solution:

1. Select TileMap
2. Go to Tile Platte Menu
3. Select "Select an area of the grid(S)"
4. In scene view hover to tile you want to delete, select the tile
   
5. Grid Selection menu should've popped up in your inspector
6. Modify Tilemap section, select "Delete Row", enter # of rows(ie 1), Click Modify

Caused by: Z Position change while painting tiles.

 

I've got this exact same problem in Unity 2021.3.27f1

I ended up just recreating the tilemaps to solve this bug.
