Alright, to familiarize ourselves with the Tiled Editor, the teacher asked us to replicate a tile-based map of a 2D platformer.

He gave us pretty much these two things:

1.) A selection of maps to copy from (Choose one map to copy)

2.) A folder with subfolders that contains 16x16 images on each subfolder (tiles)

Naturally, I started by importing the images from the folders by clicking on each folder, and importing each collection, which takes a long amount of time..(also considering the tiles for the other maps are mixed in here as well)

I used the png image as a transparent backdrop to help me place the tiles, then started placing tiles, which again, took a lot of time...

More than halfway there, I realized the width I set the map when I created it wasn't enough and tried to change the option under properties but it was grayed out. I also tried creating a new map and copying and pasting from my original one but that one doesn't seem to work either.

Is there a way to speed up the process a little bit? or salvage the tmx file? Considering that he might ask us to create more maps later on, I'd like to be a bit informed...

I've also looked up the possibility of importing the image itself, slicing it to the desired tile size and removing duplicate tiles. This way I can simply import the map png and have the software only create tiles that are used in the level.

Can this be done?

    \$\begingroup\$ To re-size an existing map, don't use the property grid (as you've noticed you can't), use the re-size option under the Map menu. It will also allow you to pick an anchor point so that the "new" area of the map extends in the direction you want. \$\endgroup\$

  • \$\begingroup\$ @Philipp My comment doesn't really address the whole question, that's why I opted for a comment. Ideally the question would be split into two, one for re-sizing and one for how to handle tiles. \$\endgroup\$

About resizing, as @bornander commented, there's a menu action for resizing that you need to use rather than directly changing the size in the Properties view.

The following article is about automating the process of creating a tile map and a tileset based on an image of a map: https://github.com/bjorn/tiled/wiki/Import-from-Image

As of now, Tiled can't do this natively, but it's something I'd like to add support for eventually.
