Download + Build

Requirements

• Windows OS
• C++20
• (Suggested) Visual Studio 2022

Downloading

1. Download the repository with git clone --recursive https://github.com/dubtcs/Next.git

2. Run _GenerateSolutions.bat to create VS2022 solution and project files.

   • You can use this any time you make changes to the premake5.lua file or just want new solutions.

How To Use

NxtEngine comes with a built in viewer, but if you want to use the raw render api or your own app, you can.

Viewer Controls

Model Scale:

[+] Scale model up

[-] Scale model down

SSAO:

[B] Toggle SSAO

Animation:

[0 - 9] Play animations.

[P] Pause animation

[G] Stop animation

App Interface

An interface is provided to hook into the main loop of the engine.

Add NextEngine/src as an include directory.

#include <NextEngine.h>

class ExampleInterface : public nxt::AppInterface
{
public:
    virtual OnUpdate(float dt, bool isFocused) override;
    virtual OnEvent(nxt::events::Event& ev) override;
};

int main()
{

    nxt::app::Launch("Your App Name", 1920, 1080);

    // AddInterface takes an std::shared_pointer to an AppInterface
    nxt::app::AddInterface(nxt::NewShared<ExampleInterface>());
    
    nxt::app::Run();
}
