I spoke of that open-source level editor yesterday in an other thread about Stendhal, but I guess it will be easier for people to find this information here.
The main features in a nutshell:
•General purpose tile map editor with XML-based map format
•Supports orthogonal and isometric maps
•Custom objects can be placed with pixel precision
•Full undo/redo and copy/paste support
•Add custom properties to tiles, layers, objects or the map
•Automatically reloads tilesets when changed externally
•Resize or offset your tile map later as needed
•Efficient tile editing tools like stamp and fill brushes
•Supports input/output plugins to open and save files in custom formats
Probably trying to make the project go from the state where the GServer and NPC server are locked to a closed-source client [and editor] that we don’t have access, to a state where we have our own [oh well, BSD and GPL are all our own, no?] client, making us free to make the changes we want to either the client or the server.
I have the feeling that a plugin to Tiled could be written to write (export) to .nw file.
But I guess that scripts could not be written directly with Tiled.
Yes, it should be easy to. I made a program that reads a .xml Tiled level and converts it to Torque X tilemaps. It isn’t that hard to convert the level data.
