old origin (fall damage)

CrazY. · **Author**

Hello, I'm trying to save player's origin before of he fell and "teleport" him to this origin if he receive fall damage. Since is there no specific way to do this, what I did then was loop through players each 0.1 seconds, save their origin and teleport they when receive fall damage.

It's working but sometimes the saved origin is the same point from where they fall, so when I teleport them, they stay falling infinitly. Also, I tried to save origin while they climb ladder, but if I teleport them to this origin, same problem happen.

Save only the last position when the player is on the ground.

That's what I did.

Code:

if (!(pev(pPlayer, pev_flags) & FL_ONGROUND))
        continue;

It's the exact same way as I did.

You mean that the origin is in the air or it's on the ground but he's falling because he has some velocity?
If it's velocity, just reset it.

Also, there's something similar on this plugin, you might want to take a look:

Do a check with traceline if the position is "safe" before saving it.

O_o

Are you sure you read the code that I provided? Because all these suggestions are there...

I actually didn't, sorry.

I really cant think about anything else than using player prethink forward in this.

PHP Code:


			
#define PLAYER_FATAL_FALL_SPEED 980.0
#define PLAYER_MAX_SAFE_FALL_SPEED 500.0 // ithink this should be 350.0 not sure
#define PLAYER_FALL_PUNCH_THRESHHOLD 250.0

static Float:fSafeOrigin[33][3];

public client_prethink(id)
{
       if(!is_user_alive(id)) return;

       if((pev(id, pev_flags) & FL_ONGROUND))
       {
            pev(id, pev_origin, fSafeOrigin[id]);
       }
       else {
            static Float:fVelocity[3]
            pev(id, pev_velocity, fVelocity)

            if( fVelocity[2] <  -PLAYER_MAX_SAFE_FALL_SPEED  ) {
                  set_pev(id, pev_origin, fSafeOrigin[id])
                  set_pev(id, pev_velocity, Float:{0.0,0.0,0.0});
            }
        }
}
