I simply want to make game tools with Godot engine, so that my game and tool visually consistent.
If it is not possible, any other recommendations for making game tools?
Godot can’t be used as a subview on WinForms/WPF, which means you will have to use a libray that’s intended to be used as a pure rendering engine instead. I can’t make recommendations as I haven’t used any of them, though.
