flWpnRecoil
As we can see, we have a neat way out, hooking the prediction code. So useful of an interface, could return false and call it a day. Alternatively, we can 0 m_pWeaponInfo->m_flRecoil and just be done with it.
You can also hook the pointer to the CDODPlayerShared vtable on the Heap to get access to IsInMGDeploy and forge a return true.
I reversed all of this by hand years ago, but having the leaked SDK is much nicer. So we see several interesting things. We could hook the RandomFloat and return zero and kill the YAW recoil here.
RECOIL_DURATION is 0.1. Useful to know since you can 0 that as well, and the recoil will be multiplied by zero removing it entirely. Notwithstanding you can hook the C_DODPlayer, and go that route if you care to.
Notice the m_flRecoilTimeRemaining, as I told you above, just zero it and be done with it.
Good old ClientThink, this is called during Simulation. No surprise how easy it is to do with FrameStageNotify ( FRAME_RENDER_START ) if that's your poison. Zero before and be done with it. Or hook GetViewAngles or SetViewAngles. On and on. The leebest way is to manually calculate the next frame's recoil yourself and set your viewangles before hand to remove it entirely. Think CreateMove here.

Colt: 1.4f Garand: 6.0f Thompson: 2.15f BAR: 5.0f Springfield: 5.6f 30cal: 20.0f Bazooka: 10.0f M1carbine: 1.4f P38: 1.4f K98: 8.0f MP40: 2.2f StG44: 5.0f Scoped98K: 6.0f Mg42: 20.0f Panzerschreck: 10.0f MauserM1932: 3.0f
Code:
if( !p->m_Shared.IsInMGDeploy() )
{
if ( prediction->IsFirstTimePredicted() )
p->DoRecoil( GetWeaponID(), m_pWeaponInfo->m_flRecoil );
}
You can also hook the pointer to the CDODPlayerShared vtable on the Heap to get access to IsInMGDeploy and forge a return true.
Code:
void C_DODPlayer::DoRecoil( int iWpnID, float flWpnRecoil )
{
float flPitchRecoil = flWpnRecoil;
float flYawRecoil = flPitchRecoil / 4;
if( iWpnID == WEAPON_BAR )
flYawRecoil = min( flYawRecoil, 1.3 );
if ( m_Shared.IsInMGDeploy() )
{
flPitchRecoil = 0.0;
flYawRecoil = 0.0;
}
else if ( m_Shared.IsProne() &&
iWpnID != WEAPON_30CAL &&
iWpnID != WEAPON_MG42 ) //minor hackage
{
flPitchRecoil = flPitchRecoil / 4;
flYawRecoil = flYawRecoil / 4;
}
else if ( m_Shared.IsDucking() )
{
flPitchRecoil = flPitchRecoil / 2;
flYawRecoil = flYawRecoil / 2;
}
SetRecoilAmount( flPitchRecoil, flYawRecoil );
}
void C_DODPlayer::SetRecoilAmount( float flPitchRecoil, float flYawRecoil )
{
//Slam the values, abandon previous recoils
m_flPitchRecoilAccumulator = flPitchRecoil;
flYawRecoil = flYawRecoil * random->RandomFloat( 0.8, 1.1 );
if( random->RandomInt( 0,1 ) <= 0 )
m_flYawRecoilAccumulator = flYawRecoil;
else
m_flYawRecoilAccumulator = -flYawRecoil;
m_flRecoilTimeRemaining = RECOIL_DURATION;
}
RECOIL_DURATION is 0.1. Useful to know since you can 0 that as well, and the recoil will be multiplied by zero removing it entirely. Notwithstanding you can hook the C_DODPlayer, and go that route if you care to.
Code:
void C_DODPlayer::GetRecoilToAddThisFrame( float &flPitchRecoil, float &flYawRecoil )
{
if( m_flRecoilTimeRemaining <= 0 )
{
flPitchRecoil = 0.0;
flYawRecoil = 0.0;
return;
}
float flRemaining = min( m_flRecoilTimeRemaining, gpGlobals->frametime );
float flRecoilProportion = ( flRemaining / RECOIL_DURATION );
flPitchRecoil = m_flPitchRecoilAccumulator * flRecoilProportion;
flYawRecoil = m_flYawRecoilAccumulator * flRecoilProportion;
m_flRecoilTimeRemaining -= gpGlobals->frametime;
}
Code:
void C_DODPlayer::ClientThink()
{
BaseClass::ClientThink();
if ( gpGlobals->curtime >= m_fNextThinkPushAway )
{
PerformObstaclePushaway( this );
m_fNextThinkPushAway = gpGlobals->curtime + PUSHAWAY_THINK_INTERVAL;

if ( IsLocalPlayer() )

UpdateIDTarget();
StaminaSoundThink();
// Recoil

engine->GetViewAngles( viewangles );
float flYawRecoil;
float flPitchRecoil;
GetRecoilToAddThisFrame( flPitchRecoil, flYawRecoil );
// Recoil
if( flPitchRecoil > 0 )
{
//add the recoil pitch
viewangles[PITCH] -= flPitchRecoil;
viewangles[YAW] += flYawRecoil;
}
// Sniper sway
if( m_Shared.IsSniperZoomed() && GetFOV() <= 20 )
{
//multiply by frametime to balance for framerate changes
float x = gpGlobals->frametime * cos( gpGlobals->curtime );
