Got caught up with something almost immediately after running that script, but finally got to try running Terraria... and it crashes after a couple seconds with a black screen. Any ideas?

@MyNameIsKeegan been getting the same error, seems to this:
Exception: System.TypeLoadException: Could not resolve type with token 01000203 from typeref (expected class 'SDL2.SDL_image' in assembly 'FNA, Version=22.2.0.0, Culture=neutral, PublicKeyToken=null') at (wrapper managed-to-native) System.RuntimeMethodHandle.GetFunctionPointer(intptr) at System.RuntimeMethodHandle.GetFunctionPointer () [0x00000] in <d1664be62cd44600bbd25f7afa292479>:0 at Terraria.Program.ForceJITOnAssembly (System.Reflection.Assembly assembly) [0x00060] in <2587bb223ae24a7fa015a01bdfbc78b9>:0 at Terraria.Program.ForceLoadAssembly (System.Reflection.Assembly assembly, System.Boolean initializeStaticMembers) [0x0000d] in <2587bb223ae24a7fa015a01bdfbc78b9>:0 at Terraria.Program.ForceLoadThread (System.Object threadContext) [0x00005] in <2587bb223ae24a7fa015a01bdfbc78b9>:0 at System.Threading.ThreadHelper.ThreadStart_Context (System.Object state) [0x00025] in <d1664be62cd44600bbd25f7afa292479>:0 at System.Threading.ExecutionContext.RunInternal (System.Threading.ExecutionContext executionContext, System.Threading.ContextCallback callback, System.Object state, System.Boolean preserveSyncCtx) [0x00071] in <d1664be62cd44600bbd25f7afa292479>:0 at System.Threading.ExecutionContext.Run (System.Threading.ExecutionContext executionContext, System.Threading.ContextCallback callback, System.Object state, System.Boolean preserveSyncCtx) [0x00000] in <d1664be62cd44600bbd25f7afa292479>:0 at System.Threading.ExecutionContext.Run (System.Threading.ExecutionContext executionContext, System.Threading.ContextCallback callback, System.Object state) [0x0002b] in <d1664be62cd44600bbd25f7afa292479>:0 at System.Threading.ThreadHelper.ThreadStart (System.Object obj) [0x0000f] in <d1664be62cd44600bbd25f7afa292479>:0

For anyone in the future, I fixed this by downloading FNA myself and changing the Makefile to have
lib/SDL2-CS/src/SDL2_gfx.cs \ lib/SDL2-CS/src/SDL2_image.cs \ lib/SDL2-CS/src/SDL2_mixer.cs \ lib/SDL2-CS/src/SDL2_ttf.cs \
at the bottom of the sources list, game runs significantly better now

It runs now! And of course much better performance, thank you for your help! Audio is a bit crunchy and crackly now which is annoying but a big step forward from black screen.

msbuild can be installed on arch linux with the mono-msbuild package

Msbuild doesn't seem to work for me, so instead I just used xbuild and it worked flawlessly

Could someone be kind enough to help me with using this with other Renderers than OpenGL on Arch Linux? I updated the Kickstarter and ran this Script, but /gldevice:Vulkan freezes right after starting the game, something about VK_DEVICE_LOST. Trying to start with /gldevice:D3D11 complains about no valid driver being found

Edit: Solved it by installing libdxvk and lib32-libdxvk from AUR. And also vkd3d and lib32-vkd3d from Extra and Multilib Repo
