To start open your game solution - find and open the player.cpp file and find the
# Open your game solution and navigate to {{path|player|cpp}}, then find {{code|preset=1|highlight=cpp|CBasePlayer::OnTakeDamage_Alive}} function (line 1708)
'''CBasePlayer::OnTakeDamage_Alive''' function around line 1708
# In the middle of this function around line 1736 lies this block of code:
<source lang=cpp>
if ( info.GetInflictor() && (GetMoveType() == MOVETYPE_WALK) &&
( !attacker->IsSolidFlagSet(FSOLID_TRIGGER)) )
{
Vector force = vecDir * -DamageForce( WorldAlignSize(), info.GetBaseDamage() );
if ( force.z > 250.0f )
{
force.z = 250.0f;
}
//ApplyAbsVelocityImpulse( force ); //drn0 disabled to remove pushback on hit
}
</source>


in the middle of the function youll find this block of code below
3. Remove the call to {{code|preset=1|highlight=cpp|ApplyAbsVelocityImpulse( force );}} from the end of the calculation. This will remove the velocity resolution from CBasePlayer::OnTakeDamage_Alive function leaving it to calculate and process still but not apply the pushback.

like so remove the call ApplyAbsVelocityImpulse( force ); from the end of the calculation


this removes the velocities resolution from the OnTakeDamage - but still Alive fuction
4. Then scroll down to line 5670 to find {{code|preset=1|highlight=cpp|void CBasePlayer::VelocityPunch( const Vector &vecForce )}}. In this function is this block of code :
<source lang=cpp>
void CBasePlayer::VelocityPunch( const Vector &vecForce )
{
// Clear onground and add velocity.
SetGroundEntity( NULL );
//ApplyAbsVelocityImpulse( vecForce ); //drn0 removing pushback on hit
}
</source>


Then proceed towards line 5670 to find the void '''CBasePlayer::VelocityPunch( const Vector &vecForce )''' function
This is the initial velocity function to set the force applied at the time, remove this as well ({{code|preset=1|highlight=cpp|ApplyAbsVelocityImpulse( vecForce );}}). Without this removed, the maximum power of an hit causes the knockback to still occur{{confirm}}, so the removal of this function  removes the knockback indefinitely as well.
within this youll find the code

|}


this is the initial velocity function to set the force applied at the time i believe so we remove that tihs too.
5. Compile the solutions - (there shouldn't be any errors but if you get any let [[User:DrN0|me]] know.)
 
Now when the player gets hit, he won't slide backwards 2 arm lengths away, he'll just stand there and eat it.
go ahead and compile the solution - there shouldnt be any errors but if you get any let me know.

This tutorial demonstrates how to remove the "push back" velocity applied to players when they get hit.

This tutorial was made using Source 2013 Multiplayer Source 2013 Multiplayer (NOT the Team Fortress 2 branch Team Fortress 2 branch)

  1. Open your game solution and navigate to 🖿player.cpp, then find CBasePlayer::OnTakeDamage_Alive function (line 1708)
  2. In the middle of this function around line 1736 lies this block of code:
if ( info.GetInflictor() && (GetMoveType() == MOVETYPE_WALK) && 
		( !attacker->IsSolidFlagSet(FSOLID_TRIGGER)) )
	{
		Vector force = vecDir * -DamageForce( WorldAlignSize(), info.GetBaseDamage() );
		if ( force.z > 250.0f )
		{
			force.z = 250.0f;
		}
		//ApplyAbsVelocityImpulse( force ); //drn0 disabled to remove pushback on hit
	}

3. Remove the call to ApplyAbsVelocityImpulse( force ); from the end of the calculation. This will remove the velocity resolution from CBasePlayer::OnTakeDamage_Alive function leaving it to calculate and process still but not apply the pushback.

4. Then scroll down to line 5670 to find void CBasePlayer::VelocityPunch( const Vector &vecForce ). In this function is this block of code : 

void CBasePlayer::VelocityPunch( const Vector &vecForce )
{
	// Clear onground and add velocity.
	SetGroundEntity( NULL );
	//ApplyAbsVelocityImpulse( vecForce ); //drn0 removing pushback on hit
}

This is the initial velocity function to set the force applied at the time, remove this as well (ApplyAbsVelocityImpulse( vecForce );). Without this removed, the maximum power of an hit causes the knockback to still occur[confirm], so the removal of this function removes the knockback indefinitely as well.

5. Compile the solutions - (there shouldn't be any errors but if you get any let me know.) Now when the player gets hit, he won't slide backwards 2 arm lengths away, he'll just stand there and eat it. This was implemented in A Nights Haunting: Source
