Basic Server Side Coding.

[page=The Tutorial]
This tutorial explains how to add headlights to the Jeep. It requires basic understanding of C++
The actual code is very simple

First open vehicle_jeep.h. Find:

  1. code:
  1. bool HeadlightIsOn( void ) { return m_bHeadlightIsOn; }
  2. void HeadlightTurnOn( void ) { m_bHeadlightIsOn = true; }
  3. void HeadlightTurnOff( void ) { m_bHeadlightIsOn = false; }
  4.  

and replace them with

  1. code:
  1. bool HeadlightIsOn( void ) { return m_bHeadlightIsOn; }
  2. void HeadlightTurnOn( void );
  3. void HeadlightTurnOff( void );
  4.  

Now for vehicle_jeep.cpp. Go to void CPropJeep::Precache( void ) and add these

  1. code:
  1. PrecachescriptSound( "Airboat_headlight_on" );
  2. PrecachescriptSound( "Airboat_headlight_off" );
  3.  

Then in void CPropJeep::DriveVehicle( ... ) uncomment

  1. code:
  1. /* if ( ucmd->impulse == 100 )
  2.  {
  3.   if (HeadlightIsOn())
  4.   {
  5.    HeadlightTurnOff();
  6.   }
  7.         else
  8.   {
  9.    HeadlightTurnOn();
  10.   }
  11.  }*/
  12.  

At the end of the file add:

  1. code:
  1. //-----------------------------------------------------------------------------
  2. // Purpose:
  3. //-----------------------------------------------------------------------------
  4. void CPropJeep::HeadlightTurnOn( void )
  5. {
  6.  EmitSound( "Airboat_headlight_on" );
  7.  m_bHeadlightIsOn = true;
  8. }
  9.  
  10. //-----------------------------------------------------------------------------
  11. // Purpose:
  12. //-----------------------------------------------------------------------------
  13. void CPropJeep::HeadlightTurnOff( void )
  14. {
  15.  EmitSound( "Airboat_headlight_off" );
  16.  m_bHeadlightIsOn = false;
  17. }
  18.  

Next in void CPropJeep::ExitVehicle( int nRole ) replace

  1. code:
  1. HeadlightTurnOff();
  2.  

with

  1. code:
  1. if (HeadlightIsOn())
  2.   {
  3.    HeadlightTurnOff();
  4.   }
  5.  

And we're done! All we needed to do was uncomment some code and add a sound to play.

the
PrecachescriptSound( "Airboat_headlight_on" );
PrecachescriptSound( "Airboat_headlight_off" );

should be notice the capitals.
PrecacheScriptSound( "Airboat_headlight_on" );
PrecacheScriptSound( "Airboat_headlight_off" );
