Godot Editor with several additions specifically for adventure games. There's a tree on the left (a tab next to Scene and Import tabs) with TreeItems for the positions and directions, a "folder" for Hotspots and each hotspot within. In the middle is the Hotspot Editor where you can define a cursor per hotspot and the polygon itself with basic functionality (add, move, erase points and a clear button that deletes the whole polygon)
The graph view where you can add Positions, define textures for each direction, set a start point via a toggle and you can define transitions between Positions by connecting the GraphNodes with each other :)
Working on an #AdventureEngine (I'll probably call it #ANgin) in #Godot :). I can define Hotspots per Position/Direction and I have a Graph where I can define the textures and connections between Positions. A basic requirements/effects system is already implemented. I still need dynamic overlays :D.
