I think that Gammer001 misses the assets from assets.bin in the Hammerwatch folder.
To have them for editing i copied the assets.bin to my project/campaign folder inside the editor folder.
For example: ".../Hammerwatch/editor/myproject_campaign/assets/assets.bin"
Then i opened a new window with the editor folder where the ResourceExtractor.exe is, and drag dropped the copy of the assets.bin onto this .exe. After that you can/should delete the assets.bin copy.
Now you have all the assets as files and can work on em. Copy, edit, etc.
If im absolute right with that procedure i dont know. It seems not to overwrite the assets from the assets.bin cause i got some resource errors on refreshing the assets (ctrl+r) or loading a level of that specific project. "assets/tilemaps/file: Multiple tileset using the same level value (assets/tilemaps/file and tilemaps/file)"
Additionaly i get an "could not find file: path/to/file.png" when i try to make an own tilemap. it seems tha the editor is looking in the Hammerwatch root folder for the image instead of my project folder.
Could someone explain how to solve that? A tutorial how to create new own assets and make them available for all projects or just for a specific one would be very nice.
And to the devs: maybe you could think about a tool in the editor to add assets
Maybe after the project/campaign thingy is implemented
