Half-Life 2

Valve | Released Nov 16, 2004

Pick up the crowbar of research scientist Gordon Freeman, who finds himself on an alien-infested Earth being picked to the bone, its resources depleted, its populace dwindling. Freeman is thrust into the unenviable role of rescuing the world from the wrong he unleashed back at Black Mesa. And a lot of people, people he cares about, are counting on him.

Report article Easy Pickable Weapon System Tutorial By Morais PGSI

This is a really easy tutorial on how to make the E key in half life 2 ep 2 pick up weapons.

Posted by MoraisPGSI on Aug 16th, 2009 digg this super bookmark
Basic Client Side Coding.

 This is a tutorial that i wanted to share with peaple who dont know how to do a easy pickable weapon system.

Just open your solution and search for basecombatweapon_shared.cpp in Client episodic - Source Files.

In the file you will find this class function :
   void CBaseCombatWeapon::DefaultTouch( CBaseEntity *pOther )

All you need to do is comment everything inside this function:   /*   Everything inside    */

Heres how it should look like:    

  1. C++ code:
  1. void CBaseCombatWeapon::DefaultTouch( CBaseEntity *pOther )
  2. {
  3.  
  4. /*
  5. #if !defined( CLIENT_DLL )
  6.   // Can't pick up dissolving weapons
  7.   if ( IsDissolving() )
  8.     return;
  9.  
  10.   // if it's not a player, ignore
  11.   CBasePlayer *pPlayer = ToBasePlayer(pOther);
  12.   if ( !pPlayer )
  13.     return;
  14.  
  15.   if( UTIL_ItemCanBeTouchedByPlayer(this, pPlayer) )
  16.   {
  17.     // This makes sure the player could potentially take the object
  18.     // before firing the cache interaction output. That doesn't mean
  19.     // the player WILL end up taking the object, but cache interactions
  20.     // are fired as soon as you prove you have found the object, not
  21.     // when you finally acquire it.
  22.     m_OnCacheInteraction.FireOutput( pOther, this );
  23.   }
  24.  
  25.   if( HasSpawnFlags(SF_WEAPON_NO_PLAYER_PICKUP) )
  26.     return;
  27.  
  28.   if (pPlayer->BumpWeapon(this))
  29.   {
  30.     OnPickedUp( pPlayer );
  31.   }
  32. #endif
  33.  
  34. */
  35. }

 


If you want a simple hint hud just add the following code:
 

  1. C++ code:
  1. #if !defined( CLIENT_DLL )
  2.   CBasePlayer *pPlayer = ToBasePlayer(pOther);
  3.   if ( !pPlayer )
  4.     return;
  5.  
  6.  
  7.   UTIL_HudHintText( pPlayer, "Valve_Hint_PicKUp" );
  8.  
  9.  
  10. #endif

Now it should look like:

  1. C++ code:
  1. void CBaseCombatWeapon::DefaultTouch( CBaseEntity *pOther )
  2. {
  3.  
  4. //SIMPLE HUD IMPLEMENTATION
  5. #if !defined( CLIENT_DLL )
  6.   CBasePlayer *pPlayer = ToBasePlayer(pOther);
  7.   if ( !pPlayer )
  8.     return;
  9.  
  10.  
  11.   UTIL_HudHintText( pPlayer, "Valve_Hint_PicKUp" );
  12.  
  13. #endif
  14.  
  15.  
  16.  
  17.  
  18. /*
  19.  
  20. #if !defined( CLIENT_DLL )
  21.   // Can't pick up dissolving weapons
  22.   if ( IsDissolving() )
  23.     return;
  24.  
  25.   // if it's not a player, ignore
  26.   CBasePlayer *pPlayer = ToBasePlayer(pOther);
  27.   if ( !pPlayer )
  28.     return;
  29.  
  30.   if( UTIL_ItemCanBeTouchedByPlayer(this, pPlayer) )
  31.   {
  32.     // This makes sure the player could potentially take the object
  33.     // before firing the cache interaction output. That doesn't mean
  34.     // the player WILL end up taking the object, but cache interactions
  35.     // are fired as soon as you prove you have found the object, not
  36.     // when you finally acquire it.
  37.     m_OnCacheInteraction.FireOutput( pOther, this );
  38.   }
  39.  
  40.   if( HasSpawnFlags(SF_WEAPON_NO_PLAYER_PICKUP) )
  41.     return;
  42.  
  43.   if (pPlayer->BumpWeapon(this))
  44.   {
  45.     OnPickedUp( pPlayer );
  46.   }
  47. #endif
  48.  
  49. */
  50. }

And if you wanna add a custom hint hud use the following code:

  1. C++ code:
  1. void CBaseCombatWeapon::DefaultTouch( CBaseEntity *pOther )
  2. {
  3.  
  4.  
  5. #if !defined( CLIENT_DLL )
  6.   CBasePlayer *pPlayer = ToBasePlayer(pOther);
  7.   if ( !pPlayer )
  8.     return;
  9.  
  10.  
  11.   UTIL_HudHintText( pPlayer, "Valve_Hint_PicKUpWeapon" );//Valve_Hint_PickUpWeapon does not exists yet
  12.  
  13. #endif
  14.  
  15. /*
  16.  
  17. #if !defined( CLIENT_DLL )
  18.   // Can't pick up dissolving weapons
  19.   if ( IsDissolving() )
  20.     return;
  21.  
  22.   // if it's not a player, ignore
  23.   CBasePlayer *pPlayer = ToBasePlayer(pOther);
  24.   if ( !pPlayer )
  25.     return;
  26.  
  27.   if( UTIL_ItemCanBeTouchedByPlayer(this, pPlayer) )
  28.   {
  29.     // This makes sure the player could potentially take the object
  30.     // before firing the cache interaction output. That doesn't mean
  31.     // the player WILL end up taking the object, but cache interactions
  32.     // are fired as soon as you prove you have found the object, not
  33.     // when you finally acquire it.
  34.     m_OnCacheInteraction.FireOutput( pOther, this );
  35.   }
  36.  
  37.   if( HasSpawnFlags(SF_WEAPON_NO_PLAYER_PICKUP) )
  38.     return;
  39.  
  40.   if (pPlayer->BumpWeapon(this))
  41.   {
  42.     OnPickedUp( pPlayer );
  43.   }
  44. #endif
  45.  
  46. */
  47. }

  273.  
  274. }
  275. }
  276.  

If you have it search for "Valve_Hint_SqueezeBait"  "%+attack2% CALL ANTLIONS" and add bellow that:
"Valve_Hint_PicKUpWeapon" "%+use% TO PICK UP WEAPON"

And your done. If you want to edit the hint text consider that the "%+use%" have to be in one of the sides for exemple:
   "%+use% TO DO SOMETHING"
      or
    "DO SOMETHING: %+use%"


Hope you guys like it.

Use E key to pick them up and have fun :)

-This only Apply for weapons not for items.

Use point_message entity or env_message entity. If you don'T know how to use them go to Valve Developer Community.
