Midnight-Engine

Midnight

Midnight is a in development minimal game engine.

Basic usage

Graphics

   //Create a camera on the start
   auto camera = std::make_shared<MN::OrthographicCamera>( -16.0f,16.0f,9.0f,-9.0f,0.1f,20.0f);

   //create a texture from a image at a path
   auto texture = MN::Texture2D::create("Assets/Textures/midnightLogo.png");


   .
   .
   .

   //On run


   camera->setPosition({0,0,2.0f});
   //BeginScene
   MN::Renderer2D::beginScene(camera);

   //Clear buffer
   MN::Renderer2D::setClearColor({0.8f,0.8f,0.8f});
   MN::Renderer2D::clear();

   MN::Transform2D simpleObjectTransform;
   simpleObjectTransform.Position = { posx,posy};
   simpleObjectTransform.Scale = { scalex,scaley};
   simpleObjectTransform.Rotation = -30;

   vec4 simpleObjectcolor = 1.0f;

   //Render a white quad at position posx,posy. Scaled by scalex and scaley. Rotated by -30.
   MN::Renderer2D::drawQuad(simpleObjectTransform, simpleObjectcolor);

   //Render a textured quad.
   MN::Renderer2D::drawQuad(simpleObjectTransform, texture);

   simpleObjectcolor = {1.0f,0,0,1.0f};
   //Render a red tinted textured quad
   MN::Renderer2D::drawQuad(simpleObjectTransform, texture, simpleObjectcolor);

   MN::Renderer2D::endScene();

Sound

   //On load
   auto effect = MN::Sound::createFromFile("Assets/Audio/effect.wav");
   auto music = MN::Sound::createFromFile("Midnight/Assets/Audio/music.wav");

   //half the original volume
   music->setVolume(0.5f);
   .
   .
   .

   //On run loop

   //Play looped
   MN::AudioEngine::playSoundLooped(music);

   if (MN::Input::isKeyPressed(MN_KEY_P)) {
       //Play a sound one time
   	MN::AudioEngine::playSound(effect);
   }

   //Stop and reset the sound
   if (MN::Input::isKeyPressed(MN_KEY_S)) {
   	AudioEngine::stopSound(effect);
   }

   //Pause, if played return in the point paused
   if (MN::Input::isKeyPressed(MN_KEY_P)) {
   	AudioEngine::pauseSound(effect);
   }

Input

   //If the user hold 'P' the sound will be played in loop
   if (MN::Input::isKeyPressed(MN_KEY_P)) {
       //Play a sound one time
   	MN::AudioEngine::playSound(effect);
   }

   //Mouse
   int mouseX = MN::Input::getMouseX();
   int mouseY = MN::Input::getMouseY();	

   //Mouse Click
   if (MN::Input::isMousePressed(MN_MOUSE_BUTTON_1)) {
   	...
   }


   //----Input events
   
   //The argument is a function or lambda.
   SubscribeKeyPress(MN_KEY_M, []() {
       TERMINAL_DEBUG("M was pressed"); 
   });

   SubscribeLeftMouseClick([]() {TERMINAL_DEBUG("Left mouse was pressed"); } );


   //-------Timers

   static MN::CountDownTimer timer = 4.0;

   //Activate for one frame every 4 seconds.
   if (timer.countTime(deltaTime) == true) {
   	//AudioEngine::playSoundLooped(testSound);
   }
