View 3d files: If my memory serves me correctly, you just double click a 3d file within the Solution Explorer, same as with png images or txt files, they also open on a seperate tab. -I dont know about animation though, as my animations were done through code, in-game.
For your own framework… I wouldnt know where to start besides online archives, tutorials, and asking people who have themselves made a framework.
-There hasn’t been one thing I have imagined, but couldn’t do with mono-game, so I dont even know why anyone would do something like that ![:slightly_smiling: :slightly_smiling:](https://community.monogame.net/images/emoji/twitter/slightly_smiling.png?v=9)
If you are actually talking about libraries, to save time coding, that seems more manageable, and there already some good ones out there, I gather. Monogame extended has its own section on the forums. -Again, I dont use anything besides monogame vanilla… When I need the same method or class in different projects, I just copy paste them. Its not usually more than a handfull…
Collision is no problem, because there so many ways to do it, you can just make up whatever you want… Even a mouse click in the menu is collision detection, so you will probably learn collision detection in your first monogame tutorial.
-Networking is something I know nothing about, other than my own thoughts:
There are so many things to do with connections, you would need to know what you are looking for, before you start to build it…
I guess you could easily write some code to ping some things, if you want to do have an immediate impact on your surroundings. -But something like a high score server for your game potentially entails all sorts of hardware choices, maybe even bills, etc…
