drizzle3d's Issues

Hide and Show Functionality for Object Structs

Is your feature request related to a problem? Please describe.
Hide and Show functionality is essential for the performance and functionality of some games and while removing the object and then adding it back in as Hide and Show works, this complexity could be removed just by adding the Hide bool.

Describe the solution you'd like
I would like to have a Hide bool in the Object Struct. Then, when the Object's are rendered, the render function can block out Object's that have true in the hide bool.

Describe alternatives you've considered
I have considered removing the object and then adding it back in to act as Hide and Show but using a Hide bool would remove this complexity.

Migrate to Linux

Is your feature request related to a problem? Please describe.
N/A

Describe the solution you'd like
The Drizzle3D and ExampleProject projects should be able to run on Linux without any Windows Subsystem or Runtimes eg: Wine.

Describe alternatives you've considered
N/A

Custom Arguments for Custom Shaders

Is your feature request related to a problem? Please describe.
Custom Arguments for Custom Shaders would allow games made in Drizzle3D to be created easier and would lift a lot of limitations.

Describe the solution you'd like
I would like to have a vector that could hold parameters that are parsed to the custom shader in the Material class. The dev/user can then choose the limit of args that are parsed to the shader.

Describe alternatives you've considered
. -

Additional context
The modifications would need to be made in Material.h and Material.cpp

2D Renderer for Drizzle3D

Is your feature request related to a problem? Please describe.
This feature request is not related to a problem.

Describe the solution you'd like
The 2D Renderer should have a tiling based system where maps and characters are implemented to make a game. Furthermore, the 2D Renderer should also be able to have it's own customizable shaders.

Describe alternatives you've considered
I have considered making a completely different project for this, but the integration's of a 3D and a 2D Render would lessen the complexity of using 2 different repositories greatly.

Additional context
The 2D Renderer should use OpenGL, and should be located in the Renderer2D.cpp and Renderer2D.h files. The 2D Renderer should use a tiling based system where you have maps and tile maps and characters as images to make a 2D Game. It should also be able to have HUD (Head-up Display) Functionality.

Physics Support

Is your feature request related to a problem? Please describe.
Physics Support would improve the game engine and would support multiple games.

Describe the solution you'd like
I would like to use the Physics Class in each Object Struct.

Describe alternatives you've considered
N/A

Additional context
The physics class must be in namespace Drizzle3D and has to export public functions and has to be added to vs inside a filter called Physics. Remember to add the ENTIRE class into Drizzle3D.h in the Exampleproject/vendor/Drizzle3D.

Vulkan Support for Drizzle3D Renderer

Is your feature request related to a problem? Please describe.
Vulkan Support for Drizzle3D would allow Drizzle3D to be used for more modern devices and would allow for more advanced graphics.

Describe the solution you'd like
Drizzle3D should be able to use Vulkan when the code below is called.

Drizzle3D::App app = std::make_shared<Drizzle3D::App>(Drizzle3D::RenderingAPI::Vulkan);

Describe alternatives you've considered
I have considered DirectX but that is only supported for Windows and would complicate the porting of the project to Linux.

Additional context
Comments are included in the Vulkan.cpp file and will be the main thing to be modified.
The OpenGL.cpp file is an example of how it should look like, but except for OpenGL.
Another file that would need to modified is the RenderingLayer.h, specifically the RenderingLayer Class and the Object Struct.
Multiple Vulkan guides are avaliable online, such as vulkan-tutorial and the recommended vkguide.
It is recommended to use vkguide as a starting point and to use the Vulkan Bootstrap.

Thanks for all your help!

Possible Memory Leaks coming from STB Image.

Possible Memory Leaks coming from STB Image that crashes other programs after prolonged use.

Materials Support.

Add Materials Support (Custom Shaders for each Object).

Make GUI Layer on top of ImGui.

Make GUI Layer on top of ImGui using the ImGuiLayer code and rename ImGuiLayer as GuiLayer.

DirectX Support

DX11 Supported is being Experimented in the DirectX Branch. Do Not Merge The DirectX Branch With Master!
