For example in the weapon_shotgun.cpp it has an override of ItemPostFrame which means that the lowering weapon code will not be called for this weapon unless you add a call to it! Remember to put the Basecombatweapon_Shared.h declarations under public or protected so that you can make use of these variables in classes which inherit basecombatweapon_shared, like the weapon_shotgun.cpp's ItemPostFrame.

This article provides a basic implementation of weapon lowering while sprinting, and preventing weapon fire while doing so.
Note:This will not work if your viewmodel doesn't have ACT_VM_IDLE_LOWERED animation declared somewhere in the .qc file.
Note:If your weapon_yourweaponname.cpp is overriding ItemPostFrame then you have to place BaseClass::ProcessAnimationEvents(); in the ItemPostFrame of that class but only if you aren't calling BaseClass::ItemPostFrame();. For example in the weapon_shotgun.cpp it has an override of ItemPostFrame which means that the lowering weapon code will not be called for this weapon unless you add a call to it! Remember to put the Basecombatweapon_Shared.h declarations under public or protected so that you can make use of these variables in classes which inherit basecombatweapon_shared, like the weapon_shotgun.cpp's ItemPostFrame. If you don't do this you will get undeclared identifier errorsThe Code
Note:This has been tested with HL2MP, 2013 and Alien Swarm SDKS.BASECOMBATWEAPON_SHARED.CPP
Hit CTRL+F and search for this code:
void CBaseCombatWeapon::ItemPostFrame( void )
Then copy and paste this above it:
void CBaseCombatWeapon::ProcessAnimationEvents(void)
{
CBasePlayer *pOwner = ToBasePlayer( GetOwner() );
if (!pOwner)
return;
if ( !m_bWeaponIsLowered && (pOwner->m_nButtons & IN_SPEED ) )
{
m_bWeaponIsLowered = true;
SendWeaponAnim( ACT_VM_IDLE_LOWERED );
m_flNextPrimaryAttack = gpGlobals->curtime + GetViewModelSequenceDuration();
m_flNextSecondaryAttack = m_flNextPrimaryAttack;
}
else if ( m_bWeaponIsLowered && !(pOwner->m_nButtons & IN_SPEED ) )
{
m_bWeaponIsLowered = false;
SendWeaponAnim( ACT_VM_IDLE );
m_flNextPrimaryAttack = gpGlobals->curtime + GetViewModelSequenceDuration();
m_flNextSecondaryAttack = m_flNextPrimaryAttack;
}
if ( m_bWeaponIsLowered )
{
if ( gpGlobals->curtime > m_flNextPrimaryAttack )
{
SendWeaponAnim( ACT_VM_IDLE_LOWERED );
m_flNextPrimaryAttack = gpGlobals->curtime + GetViewModelSequenceDuration();
m_flNextSecondaryAttack = m_flNextPrimaryAttack;
}
}
}
Now to make sure our code gets called we add ProcessAnimationEvents(); here:
void CBaseCombatWeapon::ItemPostFrame( void )
{
//Add this underneath the pOwner accessor check.
ProcessAnimationEvents();
}
BASECOMBATWEAPON_SHARED.H
Add these declarations under public at line 211 below bool IsViewModelSequenceFinished( void ); // Returns if the viewmodel's current animation is finished:
Note:We make ProcessAnimationEvents virtual so that we can override it in classes which inherit this class. virtual void ProcessAnimationEvents(void);
bool m_bWeaponIsLowered;
Finish
Now your weapon should be lowered when you hit the sprint button and you will not be able to shoot until you release the button!
