Is it possible, with the native gui, or any of the gui toolkits/system, to create a gui window that is dockable within the unity game engine(not the editor)? For example, dragging a window to the side of the screen and having it dock there.
This is kind of a second question, but if the first is possible, is it also possible to pull out a window from a tab(like pulling a tab out of chrome or firefox to make a new window)?
The answer is: Yes, it is possible with the native gui, or any of the gui toolkits/systems.
However you have to code it yourself. Don’t expect someone to post a ready-to-use solution here. Such a system requires a lot fiddling and has to be adapded to your exact needs.
Also “docking / dockable” is a wide term and there are tons of different behaviors out there.
If you want to get started with a window you can drag around, I made a blog post outlining how to do that here.
Basically, you add a Collider to the element you want the user to click to drag, add the UIDragObject script on to that object, and drag the object you want to move around to the UIDragObject’s “Target” parameter.
More complex behaviors and animations can be triggered with Colliders and Triggers, but as Bunny83 said, no-one’s going to write them for you.
