Source Modding - Parte 2 - Everything Is Essence

Na parte anterior do tutorial, aprendemos o trabalho básico com o VPC e a impressão de mensagens no console do desenvolvedor.



Nesta parte do tutorial, vamos dividir o sistema de entidades, aprender como criar classes e criar nossa primeira entidade lógica.





Novamente termos

  2. :



    // cbase.h -  .
//           .
#include "cbase.h"
// memdbgon.h -     new  delete
// memdbgon must be the last include file in a .cpp file!!!
#include "tier0/memdbgon.h"


  3. CLogicFive CLogicEntity:



    class CLogicFive : public CLogicEntity {
    DECLARE_CLASS( CLogicFive, CLogicEntity );
public:
    // ...
private:
    // ...
};


    -! DECLARE_CLASS()? , . — ThisClass BaseClass ( ...).



  4. public:



    public:
    DECLARE_DATADESC();
    void Input_Tick( inputdata_t &id );


    ?



    • DECLARE_DATADESC() , .
    • void Input_Tick( inputdata_t &id ) , tick.


  5. private:



    private:
    int m_iTicks = 0;


  6. " " logic_5.

    ( !) — LINK_ENTITY_TO_CLASS()!

    :



        // ...
    int m_iTicks = 0;
};
LINK_ENTITY_TO_CLASS( logic_5, CLogicFive );


  7. , 4:



    BEGIN_DATADESC( CLogicFive )
    DEFINE_FIELD( m_iTicks, FIELD_INTEGER ), //   
    DEFINE_INPUTFUNC( FIELD_VOID, "tick", Input_Tick ), //

    • BEGIN_DATADESC() — , .
    • DEFINE_FIELD() — , . , !
    • DEFINE_INPUTFUNC() — , . (FIELD_VOID), tick Input_Tick.
    • END_DATADESC() — , .


  8. Input_Tick:



    //   tick()
void CLogicFive::Input_Tick( inputdata_t &id )
{
    m_iTicks++;
    if( m_iTicks % 5 == 0 )
        //       ,   !
        ConColorMsg( Color( 255, 255, 0 ), "logic_five: Another fifth tick!\n" );
}


  9. [] VPC :

logic_5 —
