Drawing sprites/graphics on screen without the use of a window.

Question

I know this is a long shot, but would it be possible to create a game that doesn't use a system window? Or would I just have to learn how to do this in OpenGL or something?

I wanted to program something like a desktop companion. Would it all be possible to make a window transparent, or make the the boarder invisible?

OpenGL and other rendering apis render to a window. You can however create borderless windows and set transparency as well. I don't believe this is anything you can use Unity for though :/

$$anonymous$$e sad :P I might just have to draw it in a small window. Is there a way to get rid of the top bar of the program? (where the game of the application and the close/$$anonymous$$/max buttons are?)

You might be able to set such preferences though pinvoke. See http://pinvoke.net/ for more info. Basically you'd need to use native win32 calls. Find the window handle and set preferences for it. http://www.csharphelp.com/2006/08/get-current-window-handle-and-caption-with-windows-api-in-c/

I am afraid you'll have to do some google work. I don't have this fresh in $$anonymous$$d but you could look for "win32 api remove window borders" or something.

The win32 api are C/C++ dlls you use. Use interop to make wrappers for those functions from the native dlls in C#. It might be possible in JS as well, I am just not that accustomed to it.
