1) Direct12, so, Windows 10 or 11, (64bit) but, since Windows 10 is now defunct by MS... Support for it in regards to questions etc etc will be Windows 11 only.
Here is the Steam survey on Windows OS's:
Windows - 92.33% (-4.28%)
Windows 11 64 bit - 66.85% (+10.57%)
Windows 10 64 bit - 25.36% (-14.89%)
Windows 7 64 bit - 0.08% (+0.03%)
So as you can see, on Steam... Windows 11 has the lions share amongst Steam gamers. There is no plans for multi-platform, but, Linux may be a path one day... MacOS, no, definitely not... Too much Apple fannying on.
The reason being is that it's currently just Windows only is pretty much time... I have no time to support other platforms such as Android etc etc I'm just one bloke, this is the delimiter factor, and the amount of languages that target multiple platform support fall by the way side... BlitzMax had it, GLBasic had it, AGP now has it (But some of it has been patched up by a user)
I'm planning to make BambooBasic the best it could be, and multiple platform targets isnt the way I can get it there... Like I said up top... I'm ultimately making it for myself, and all I want is Windows!
2) The manual I have no real stats on... All the functions are covered and documented, there is various things I've covered too... But all in all, any "guides" and stuff will be implemented when I'm close to finishing the beta test stuff, like, how you how to make a game, maybe a few youTube videos, stuff like that... But yeah, actual function reference wise, they are done... 100% on that part! :) <--- Which was a relief! :D lol
