Background issues.

A single change in a tileset resulted in something problematic.

As you can see here: , this what it used to look like. No problems with the tileset there, but then...

A quick switch to another tileset, and BOOM! This is what we've got.

I can't find a way to erase it, which is my problem; trying to use the B layer solution presented in the Help menu is no good.

Any help, please?

Each map can have only a single tileset, and if you change that tileset you change all tiles on the map to the new tileset.


If you want to have the old look back, then you have to change back to the old tileset.


If you want to add tiles from another tileset to the map, you have to add those tiles into the tileset, not change the tileset.


That is easy if there is a fitting empty slot in the tileset (you cannot place a tilesheet into the wrong slot, for example A2 tilesheets will not work in the A1 slot, only the B to E slots have the same format).


If all slots of the tileset are already filled, then you need to export a tilesheet with unused tiles and replace those tiles with the wanted new tiles with a program like GIMP or Photoshop.

...I'll accept being at fault for not stating everything. I *thought* I did, but then again I'm currently suffering from post-wisdom tooth-removal shock or something... I keep not writing everything.

You'll notice there's stuff at the background where there wasn't. I don't know how to erase it. Yes, I know it says 'use layer B to erase', but for some reason it doesn't work with mine.

The system only provide one tileset type, one tileset can consist of 5 tabs from A until E, you can look at Database Tileset, there's nothing you can do except what Andar has been recommended =).

The background you mean is the brown tile in behind the actual map(at the second image)? Perhaps that is a tile that is not exist in your former tileset palette. But I don;t know, it's to risky for changing tileset when your map is already took a form. And what do you mean with 'use layer B to erase'? I don't get it. :unsure:

No, it can't - because the B1 tile doesn't erase, it replaces the upper layer tile at that position with itself. That is the reason why the B1 tile always have to be transparent and set to star - because it's placed on every position as the upper layer by default.
And for the bottom layer this is similiar - there is no function to erase anything, you can only place a transparent tile on those positions where you want the tile to disappear. OK, the bottom layer starts as transparent on a new map - but once you place something, you can only replace it - never erase it.


What happened here is that in the original tileset, there was a transparent tile - and you use that sometime in the past to erase wrong tiles in the bottom part of your map. But with the new tileset, there was no transparent tile at the same ID, so the transparent tile turned into the background you see.


As a result, you have only two options to solve your problem:


1) Use GIMP or Photoshop to place a transparent tile in the new tileset (preferably replacing the unwanted tile that is currently used on the map). If you replace another tile, you'll have to repaint that part of your map with the transparent tile.


2) make a new map and copy only the wanted parts of the old map to that one


And for the future just always remember: there is no erase in the RM map editor, you can only repaint with a transparent tile.

Actually, there IS a way to "erase" A tiles (Andar, this may just be semantics. You're right that you can only replace, but you didn't mention this option). Assuming the "bad" tiles are on the background (A) layer, all you need to do is RIGHT-CLICK on any empty space in your map to copy the non-tile. Then you can "paint" the non-tile anywhere you want, effectively erasing A tiles. (If you don't have any empty spaces, you can copy from a new blank map and it'll still work.)

I just tested this to make sure.

Thank you. That helped out.
