This is my Game Engine created by use of Vulkan API

VulkanEngine

I've created my own little Game/Rendering Engine using Vulkan API.

Getting Started

Visual Studio 2022 is recommended

1. Downloading the repository:

Start by cloning the repository with git clone --recursive https://github.com/PrakarshPanwar/VulkanEngine.git.

2. Setting up Project

1. Run the VkGenProjects.bat file found in main repository to generate Project Files.
2. Build Assimp submodule by typing below text in Command Prompt

cd Assimp 
cmake -DASSIMP_BUILD_ZLIB=ON CMakeLists.txt

3. Open Assimp.sln in Visual Studio and build solution.
4. One prerequisite is the Vulkan SDK. If it is not installed, then install VulkanSDK here.
5. After installation, create a folder VulkanSDK in vendor and copy all the folders of VulkanSDK in VulkanCore/vendor/VulkanSDK.
6. Again run VkGenProjects.bat to link debug libraries in shaderc.

Big Features to Come

• Advanced UI Features
• Cascaded Shadow Maps
• Integrated 3D Physics Engine like NVIDIA-PhysX, box2d

vulkanengine's Issues

Textures are absent when loading models through Assimp

Whenever models are loaded through Assimp Library then model is shown in black color not in a given texture.

Need to Add Submodules in Repository

Currently there are no submodules in repo, will be added soon in future.

Problem having Resizing Window

When resizing Application window sometimes it crashes but other than that Scene Image does not fit in with viewport at all.

Need of Viewports in ImGui and Dock Space

Viewports are required to render the Vulkan Scene to better manage Vulkan-Editor. Addition of separate VkFramebuffer and VkRenderPass for ImGui are required. Addition of DockSpace is also required to manage several ImGui Panels.

Add ImGui to Engine

ImGui is present in project dependencies but is not utilised in Engine.

Mouse flickering in ImGui Textboxes and Windows cause Engine to crash

Whenever, mouse hovers over borders of ImGui windows and textboxes, cursor flickers from normal to other states, after too much of flickering engine crashes, it is likely caused due to data race in GImGui.InputEventsQueue which is custom ImGui Vector ImVector.

Integrate VMA in Vulkan Buffers

Now issues regarding VMA are gone, so we need to start implementing it in Buffer classes.

Add Runtime Layer

This layer will only have the main scene with No Editor UI

Event Issues

When using keyboard events such as scrolling, it causes both ImGui scrolling and Zooming of Camera
