Odin

A Multiplayer FPS Built From Scratch

Requirements

• Vulkan SDK
• Vulkan-compatible graphics hardware & up-to-date drivers
• Visual Studio 2017+

This is a fork of the code repo for this excellent series of articles on network programming. http://www.codersblock.org/blog/multiplayer-fps-part-1

Things done to get original repo working

Change project working directory to odin/data. Change Vulkan lib directories to "Lib32" for Win32 configs & "Lib" for x64 configs. Turn off warning treated as error for all configs. Not a long term fix, but it gets the app building.

Further Problems

Shader validation errors are triggering breakpoints:

[graphics::vulkan::Validation]  [ UNASSIGNED-CoreValidation-Shader-InconsistentSpirv ] Object: VK_NULL_HANDLE (Type = 0) | SPIR-V module not valid: Vulkan spec doesn't allow BuiltIn VertexId/InstanceId to be used.
  %gl_VertexID = OpVariable %_ptr_Input_int Input

odin.exe has triggered a breakpoint.

[graphics::vulkan::Validation]  [ UNASSIGNED-CoreValidation-Shader-InconsistentSpirv ] Object: VK_NULL_HANDLE (Type = 0) | SPIR-V module not valid: In the Vulkan environment, the OriginLowerLeft execution mode must not be used.
  OpExecutionMode %main OriginLowerLeft

odin.exe has triggered a breakpoint.

These can be "continued" through & the app will seemingly run just fine afterwards. Need to fix those validation errors at one point.
