[Solved] [HELP] Detect or block player healing events after drowning in water?

felhasznalo · **Author**

When a player comes out of water after drowning (taking DMG_DROWN damage), his/her health will regenerate slowly over time.
Where could I find this healing event, and how could I block it?

No event needed.

PHP Code:


			
const m_idrowndmg       = 345
const m_idrownrestored  = 346

set_pdata_int(id, m_idrownrestored, get_pdata_int(id, m_idrowndmg))

m_idrowndmg is the drown damage that a player got.
m_idrownrestored is the ammount of hp that was restored after the drown occured. We trick the game and make it think that all the damage was restored. You may also reset m_rgbTimeBasedDamage[itbd_DrownRecover](if for amxx < 1.8.3 use set_pdata_char, else set_pdata_byte) but game will do this on next drown dmg automatically.

I believe you can just hook CBasePlayer::TakeHealth():

Code:

/**  
 * Description:     Usually called whenever an entity gets a form of a heal.  
 * Forward params:  function(this, Float:health, damagebits); 
 * Return type:     Integer. 
 * Execute params:  ExecuteHam(Ham_TakeHealth, this, Float:health, damagebits); 
 */ 
 Ham_TakeHealth

I don't know what else is it called for, but it is called to recover player from drowning. In that event you could play with member offsets HalmetEagle posted before me, to check if he is really recovering.

@HamletEagle: I know this goes without saying, but you need an event or some means of detecting when the player took this damage or heal. Also, it would be better to set m_idrownrestored one time to a value that will make the condition always false if (m_idrowndmg > m_idrownrestored), instead of incrementing it with each piece of damage.

This will set m_idrownrestored on the first heal (which is blocked) which will prevent any future heals from being called on that player for the rest of the round.

PHP Code:


			
#include <amxmodx>
#include <hamsandwich>
#include <fakemeta>

public plugin_init() 
{
    RegisterHam( Ham_TakeHealth , "player" , "TakeHealth" );
}
 
public TakeHealth( iPlayer , Float:fHealthHealed , DamageBits )
{
    const m_idrownrestored = 346;
    
    set_pdata_int( iPlayer , m_idrownrestored , 100 );
    
    return HAM_SUPERCEDE;
}

I meant no event need to be blocked. Of course he need an event to detect, but his question was how to block it, so I assumed that he already knows.
Anyway, setting to 100 doesn't seem to be best way, there are custom mods like furien/zm which set health to bigger values. Probably better to get his health at spawn and use that value.

I thought about setting it at spawn as well but thought it was more relevant to set it when a heal attempt is made instead of setting it on every player every round. I went with 100 assuming no other mods..set it to 5000 instead? I'm not sure what data type is used in the game to store that value.

In zm some players have like 60.000 hp. I think that we should not hardcode the value and do something like that(wrote the snippet from phone, but you get the point).

PHP Code:


			
new Float:PlayerHealth[33]

public CBasePlayer_Spawn(id)
{
    if(is_user_alive(id)
    {
         pev(id, pev_health, PlayerHealth[id])
    }
}

//later, in CBasePlayer::TakeHealth
set_pdata_int(id, m_idrownrestored , PlayerHealth[id])

**Bugsy**

I don't see the point in setting it to health or any other retrieved value, can you give a reason for this? Hard coded to a value that will always make the condition false to prevent TakeHealth from being called again seems best to me.

**HamletEagle**

Because we don't know what value to use, it really depends on the server and the mod that is running.

**Bugsy**

Suppose you used spawn health but there is a mod that gives additional health beyond spawn health? Simply setting the value to an unreachably high value is better and safer IMO.
