Godot: Automatic conversion of TileSet source scene to TileSet resource on save

[Bladum]

Godot version:
3,0 Beta 2

Issue description:
Auto export tileSet to tres file on tileset save would be nice feature.

Steps to reproduce:
Create tileset as usual. Export it to Tres file using menu. New Tres file is created but its manual process. Automatic export on Save of tileset would be nice.

I guess you mean the engine to remember the tscn was exported to a tileset, but what if the changes you made were for another new tileset?
Or what if you do not want to merge but overwrite?

[Zylann]

Tbh this would be a non-issue if we had a dedicated tileset editor (getting there with the autotile dock though)

[vnen]

Another option is to accept Scenes as TileSets with the new import system.

[blurymind]

@vnen I though about the same thing - it would definitely simplify the process

@MarianoGnu mentioned in another issue that there is a plan to allow the new tile editor to directly load atlas image files - that would be even better to have..
Since the autotile editor can be used to set collision, occlusion, pathfinding and everything else that we would use in 99% of the cases - there will be no need to even create a new tileset scene in most cases. Just load the tileset image file straight into the new tile editor. Of course we still keep the option to use custom tileset scenes

[MarianoGnu]

@blurymind i'm not sure about what do you mean with "directly load atlas image files", TileSet loads textures and then you select a region, that's exactly what an atlas is...

There's an open PR for allowing edit every tile on the new Autotile/Tileset Dock ( #15262 ) but it has been kicked to 3.1, maybe you can convince @akien-mga to merge it in 3.0 if finished (since it's an usability improvement rather than a new API feature)

[blurymind]

@MarianoGnu I am referring to the ability to load an image file as a resource straight into the TileMap node - without the requirement to create a new scene file in godot, set nodes in it to be tiles and then export from it another file - the tileset.
The current workflow makes it a pain to setup and update tilesets - even with the new autotile editor

You noted in another comment that it is a planned feature:
https://github.com/godotengine/godot/pull/15262#issuecomment-354762925

You can currently create a tileset resource in godot editor's tilemap node inspector. However you can not load into it the image file you would like the autotile editor to use as an atlas. In fact you can't do anything with it:

@damarindra probably knows about this too

[eon-s]

That "path" entry never worked for me on any node, even on 2.
New tileset should have an entry like Arrays to add tiles manually to the resource, can be faster for prototyping (but that is for another issue I guess).

[MarianoGnu]

@blurymind you can already do this from TileSetEditorPlugin's toolbar button, adding a Tile will add an empty tile to the tileset, you can also merge from scene using this menu instead of selecting the file to merge, this is better since you can can reload the file without saving it. Only missing feature is displaying on inspector only current tile instead of all (maybe hundreds) of them

[MarianoGnu]

none of these improvements are being worked on right now because feature freeze, they wonr make it in 3.0 no matter how many PR we make, that's we we try to focus on bugfixes

[phil123456]

"create from scene is the dumbest thing ever" you have to create scene and every tile so this is bloody useless
is it so hard to have a built in function that slices a bloody images grid like and create the tile set automaticaly ?

[MarianoGnu]

@phil123456 now that autotile editor is kind of functional this can be done much more easily, Damar Indra have plans to make an sliced tile to work this case out

[blurymind]

@MarianoGnu we need a "Create from Image file" function. And when the artist updates the image file, so should the tileset

The intermediate scene should be optional, not required imo- it creates extra effort to set up a tileset and keep updating it

[akien-mga]

What's the status on this @MarianoGnu? Is it addressed by recent changes, or should it be moved to the 3.2 milestone?

[MarianoGnu]

Well, importing tilesets from scenes makes no sense anymore imho, making tiles is much faster with the new editor than creating thousands of sprites in an scene, also the scene converter doesn't support TILE_ATLAS or AUTOTILE by default, the only thing that this can do and the tileser editor can't is setting the pivot.

@reduz have mentioned that he wanted to rework the TileSet/TileMap completely to make it more straightforward (maybe making different kinds of resources and nodes for every kind of cell/isometric/hex maps)
So i dont know. At least i dont import TileSets from scenes myself anymore...

[akien-mga]

Indeed, this is no longer so relevant now that we have the new TileSet editor, so closing.
