Getting Started

The CMIL interface is composed of three main parts:

• 1. The InputAction class heirarchy, used to specify actions:

        class helpAction: public ModAction, CoordAction {
          public:
            helpAction(const std::string& name) : InputAction(name), ModAction(name), CoordAction(name) {}
  
            void doPress() { 
              std::cout << "help action pressed " << std::endl;
              std::cout << std::endl;
            }
            void doRelease() { 
              std::cout << "help action released " << std::endl;
              std::cout << std::endl;
            }
  
            void runCoord(unsigned long int x, unsigned long int y, int xrel, int yrel) {
              std::cout << "help x: " << x << " y: " << y << " xrel: " << xrel <<" yrel: " << yrel << std::endl;
            }; 
        };
  

• 2. The System, which provides valid events to InputActors. The derived SDLSystem for example, is configured to provide translated SDL events exclusively:
  
  

            system_ptr = new cmil::SDL::SDLSystem();
  

  
  

• 3. The InputActor , which receives events from the CMIL system. The provided ContextActor for example, then triggers the necessary actions through the use of a InputContext member:
  
  

          m_actor  = new cmil::ContextActor(system_ptr);
  
          using cmil::Ev;
  
          m_actor->addNormal( Ev("F1") << helpAction));
          m_actor->addCombo( Ev("A") << Ev("B") << Ev("Up") << Ev("Down")  << specialKick);
  
          system_ptr -> attach(m_actor);
