Easy Pickable Weapon System Tutorial By Morais PGSI

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:

void CBaseCombatWeapon::DefaultTouch( CBaseEntity *pOther )
{

/*
#if !defined( CLIENT_DLL )
	// Can't pick up dissolving weapons
	if ( IsDissolving() )
		return;

	// if it's not a player, ignore
	CBasePlayer *pPlayer = ToBasePlayer(pOther);
	if ( !pPlayer )
		return;

	if( UTIL_ItemCanBeTouchedByPlayer(this, pPlayer) )
	{
		// This makes sure the player could potentially take the object
		// before firing the cache interaction output. That doesn't mean
		// the player WILL end up taking the object, but cache interactions
		// are fired as soon as you prove you have found the object, not
		// when you finally acquire it.
		m_OnCacheInteraction.FireOutput( pOther, this );
	}

	if( HasSpawnFlags(SF_WEAPON_NO_PLAYER_PICKUP) )
		return;

	if (pPlayer->BumpWeapon(this))
	{
		OnPickedUp( pPlayer );
	}
#endif 
	
*/
}

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

#if !defined( CLIENT_DLL )
	CBasePlayer *pPlayer = ToBasePlayer(pOther);
	if ( !pPlayer )
		return;


	UTIL_HudHintText( pPlayer, "Valve_Hint_PicKUp" );
	

#endif

Now it should look like:

void CBaseCombatWeapon::DefaultTouch( CBaseEntity *pOther )
{

//SIMPLE HUD IMPLEMENTATION
#if !defined( CLIENT_DLL )
	CBasePlayer *pPlayer = ToBasePlayer(pOther);
	if ( !pPlayer )
		return;


	UTIL_HudHintText( pPlayer, "Valve_Hint_PicKUp" );
	
#endif
	
	


/*

#if !defined( CLIENT_DLL )
	// Can't pick up dissolving weapons
	if ( IsDissolving() )
		return;

	// if it's not a player, ignore
	CBasePlayer *pPlayer = ToBasePlayer(pOther);
	if ( !pPlayer )
		return;

	if( UTIL_ItemCanBeTouchedByPlayer(this, pPlayer) )
	{
		// This makes sure the player could potentially take the object
		// before firing the cache interaction output. That doesn't mean
		// the player WILL end up taking the object, but cache interactions
		// are fired as soon as you prove you have found the object, not
		// when you finally acquire it.
		m_OnCacheInteraction.FireOutput( pOther, this );
	}

	if( HasSpawnFlags(SF_WEAPON_NO_PLAYER_PICKUP) )
		return;

	if (pPlayer->BumpWeapon(this))
	{
		OnPickedUp( pPlayer );
	}
#endif 
	
*/
}

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

void CBaseCombatWeapon::DefaultTouch( CBaseEntity *pOther )
{


#if !defined( CLIENT_DLL )
	CBasePlayer *pPlayer = ToBasePlayer(pOther);
	if ( !pPlayer )
		return;


	UTIL_HudHintText( pPlayer, "Valve_Hint_PicKUpWeapon" );//Valve_Hint_PickUpWeapon does not exists yet

#endif
	
/*

#if !defined( CLIENT_DLL )
	// Can't pick up dissolving weapons
	if ( IsDissolving() )
		return;

	// if it's not a player, ignore
	CBasePlayer *pPlayer = ToBasePlayer(pOther);
	if ( !pPlayer )
		return;

	if( UTIL_ItemCanBeTouchedByPlayer(this, pPlayer) )
	{
		// This makes sure the player could potentially take the object
		// before firing the cache interaction output. That doesn't mean
		// the player WILL end up taking the object, but cache interactions
		// are fired as soon as you prove you have found the object, not
		// when you finally acquire it.
		m_OnCacheInteraction.FireOutput( pOther, this );
	}

	if( HasSpawnFlags(SF_WEAPON_NO_PLAYER_PICKUP) )
		return;

	if (pPlayer->BumpWeapon(this))
	{
		OnPickedUp( pPlayer );
	}
#endif 
	
*/
}

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.
