I guess, that they test the things first in Tier 2 and it will slowly make its way into Tier 1.
It also maybe, that not all "Player" support these commands, because of the underlaying restrictions from hardware and or the OS.
Maybe some are only for Vulkan.
I am still trying to figure out, how I could integrate another texture format other than PNG or JPEG into this thing.
I also try, to not use other libs. So it could still be cross-platform.
But simple things as creating an Array with dynamic size or a Linked-List is not well documented.
So I have to mix up C++ help tutorials and AppGameKit Tier 1 Basic tutorials. Also the Template didn't work from the start.
I was using the Source of PONG and cut the rest out. I had to change directories for the AppGameKitWin.LIB, and some directory for Source and something in the C++ LINKER.
I am glad, I could get it to run in Visual Studio 2019. But I gave up for the moment to use it in Android Studio. I still can't compile it for Android. The setup is harder than it needed, I guess.
And for these Tier 2 questions, I would prefer, if we had a section for Tier 2 alone.
