I was surprised to notice tileset / tilemap support seems to be a bit unclear and labeled as a new experimental feature. Apparently it exists but there’s no ability to edit tiles internally: I worked with Tiled before and am always happy to use it, but was still curious if an editor inside GDevelop itself will ever exist. Also if things like map format may change and break later thus I should wait, though I presume the Tiled JSON format will never be deprecated, ideally used by the engine’s own editor in the future.
The page I looked at also suggested you need to do collisions separately in GDevelop after exporting a map from Tiled. That part has me tempted to wait: I might make quite a few maps then edit them in the future, not sure if I should go for doing the extra work of drawing collisions separately, especially if their format may later change to allow defining them in tilesets.
Strangely enough this video from 2017 shows a tileset editor but I can’t find it in recent versions. They don’t mention it being an addon, seems to have been a core feature at the time. Was that removed at some point, or am I just silly and not able to find it in the new menus?
