Useless stuff, but someone may be interested...

cstrike values (should be the sames for czero)

#define PLAYER_FATAL_FALL_SPEED 980.0
#define PLAYER_MAX_SAFE_FALL_SPEED 500.0
#define PLAYER_FALL_PUNCH_THRESHHOLD 250.0 // found by arkshine

player.h (those are half life default values)

#define PLAYER_FATAL_FALL_SPEED		1024// approx 60 feet
#define PLAYER_MAX_SAFE_FALL_SPEED	580// approx 20 feet
#define DAMAGE_FOR_FALL_SPEED		(float) 100 / ( PLAYER_FATAL_FALL_SPEED - PLAYER_MAX_SAFE_FALL_SPEED )// damage per unit per second.
#define PLAYER_MIN_BOUNCE_SPEED		200
#define PLAYER_FALL_PUNCH_THRESHHOLD (float)350 // won't punch player's screen/make scrape noise unless player falling at least this fast.

Would be better to have some kind of stock, those codes can't help some people

[ConnorMcLeod]

That is just to let you know cs values.
flDamage that is passed into TakeDamage is already the final damage taken, so make a stock would be even more useless than having created that thread.

It's not the fall that kills ya, it's the sudden stop at the end. People have been jumping out of planes for years, while so do die jumping out of a plane, such as the case of an elderly gentlemen who had a heart attack secondary to the adrenaline flow caused by that said individual jumping out of the plane, most of the times it does not happen. People do die from multi vehicle collisions, jumper downs, and gun shot wounds every day. They them selfs did not die because of the first act, they died because of the injury(s) they received because of that act. It's the blood loss, the cardiac arrest secondary to the blood loss (hypovolemia) giving you a pulse less rhythm on the EKG known as PEA (Pulse-less Electrical Activity).

I'm going through paramedic school right now, so I find this all very intresting, injury mechanics in general is quite an intresting field but not simulated within the game engine.

That said tho, I would of taken terminal velocity as the max speed of any falling object and then found the velocity that f = t / v gives you a point where f is so great that the human system instantly collapses, or causes fatal injury's.

I gave up there.
