Okay, time to explain a bit, so you can learn something :-)
At first we''ve defined 4 new variables:
int m_oncharge
float m_flChargeStart
float m_flReleaseCharge
float m_Damagefactor
m_oncharge is used to indicate if we''re charging the crowbar at the moment
m_flChargeStart is the time we started to charge
m_flReleaseCharge is the time we ended to charge
m_Damagefactor is the amount of dammage we''re adding to the standard damage (standard is 25 i think)
Now we look at SecondaryAttack.
There we initialise the Starttime, if it has''nt been done before.
Then we say that the WeaponIdle-function will be called after 0.5 sec
In WeaponIdle we set the ReleaseCharge time, than we calculate the amount of damage to add and call the Swing function to attack.
In the Swing function we go to the TraceAttack call and add our Damagefactor to the normal damage.
You''ll notice, that the crowbar will react a bit slow. That''s to make it harder to hit witch a charged crowbar. If you wanna reduce or increase this effect, reduce or increase the m_flTimeWeaponIdle variable in SecundaryAttack
