DearImGui Vulkan backend adapted to work with VK_KHR_dynamic_rendering
// dear imgui: Renderer Backend for Vulkan
// This needs to be used along with a Platform Backend (e.g. GLFW, SDL, Win32, custom..)
// Implemented features:
// [X] Renderer: Large meshes support (64k+ vertices) with 16-bit indices.
// [x] Renderer: Multi-viewport / platform windows. With issues (flickering when creating a new viewport).
// [!] Renderer: User texture binding. Use 'VkDescriptorSet' as ImTextureID. Read the FAQ about ImTextureID! See https://github.com/ocornut/imgui/pull/914 for discussions.
// Important: on 32-bit systems, user texture binding is only supported if your imconfig file has '#define ImTextureID ImU64'.
// This is because we need ImTextureID to carry a 64-bit value and by default ImTextureID is defined as void*.

PipelineBuilder builder{};
builder.SetShader(someShader);
builder.SetRasterizer(vk::PolygonMode::eFill, vk::CullingModeFlagBits::eBack); // Specify filled polygons, with backface-culling
// other functions
// Create a pipeline from the builder
VulkanPipeline somePipeline = builder.BuildGraphics();
// Now we can re-use the builder, change some properties and create a new pipeline
builder.SetShader(someOtherShader);

This is a simple function that makes checking variables for null much easier. It can even log a simple message. (in this case to the Unity debug console)
public static class Utils
{
public static bool NullCheck(this object obj, string msg = "")
{
if (obj == null)
{
if (msg != "")
Debug.LogError(msg);
return true;
}

This is a simple script that creates a Unity Editor Window that shows the current state of the Editor. Useful for when you want to know if the Editor is still compiling your code.
// === EditorStateVisualizer By Seppe Dekeyser. ===
using UnityEngine;
using UnityEditor;
enum EditorState
{
Ready,
Compiling,
