How do I use damagetype to filter out damage ONLY done by bullets?

Like this?

 register_event("Damage", "takedamage","b", "2>1", "3 = (1<<1)");

?

From hlsdk_const I found that list if damage types and for bullets it states:

 #define DMG_BULLET 1<<1

How do I use bitwise values in this case?
Or alternatively how could I read value of the third parameter and filter the rest with a simple if statement?

i think this could be used in ham_takedamage

register_event("Damage", "takedamage","b", "2>1", "3=2");

I have tried that now and it doesn't work at all. The function just doesn't get called.
I even put client_print in it to check, but nothing happens.
Is there some other way I can hook a function to be called from only bullet damage?

Or possibly use ham_takedamage (which I don't know how to use) for the same purpose? (Would loading hamsandvich just for that one thing be worth it more than using register_event...)?

Well using ham is better and simple.


Hook

PHP Code:

RegisterHam(Ham_Takedamage, "player", "player_taking_damage") 


Function

PHP Code:

public player_taking_damage(victim, inflictor, attacker, Float:damage, Damagebitsum)
{
       if(Damagebitsum == 2)
       {
                 /// code here
       }
}

Welp I tried it again and it still doesn't work.

public plugin_init()
{
        RegisterHam(Ham_TakeDamage, "player", "takedamage");
}
public takedamage(Victim, Useless, Attacker, Float:damage, damagebits)
{
if(damagebits == 2)
{
	health = get_user_health(Attacker);
	if(health == 100)
	{
		return HAM_HANDLED
	}
	if((health + (damage*0.5)) >=100)
	{
		set_user_health(Attacker, 100);
		return HAM_HANDLED
	}
	set_user_health(Attacker, floatround(((damage*0.6)+health)));
	emit_sound(Attacker, CHAN_WEAPON, "misc/arrow_impact_crossbow_heal.wav", 0.7, ATTN_NORM, 0, PITCH_NORM);
}
}

Even without the damagebits == 2 check it still doesn't work :L
Thanks for trying atleast!
My version with Damage message worked sorta, but the user would get healed if he took fall damage. Should I post the entire plugin instead?

[Natsheh]

I suppose it should work fine

public plugin_init()
{
        RegisterHam(Ham_TakeDamage, "player", "takedamage");
}
public takedamage(Victim, Useless, Attacker, Float:damage, damagebits)
{
if(damagebits == 2)
{
	health = get_user_health(Attacker);
	
	if((health + (damage*0.5)) >=100)
	{
	        SetHamParamFloat(4, 0.0)
		return HAM_HANDLED
	}
	
        SetHamParamFloat(4, (damage*-0.5))
	emit_sound(Attacker, CHAN_WEAPON, "misc/arrow_impact_crossbow_heal.wav", 0.7, ATTN_NORM, 0, PITCH_NORM);
        return HAM_HANDLED;
}

rerurn HAM_IGNORED
}

Shouldn't it be (damagebits & DMG_BULLET) ?

not really, read more about bitsums....

(damagebits & DMG_BULLET) its if damagebits contain 2 >> lets imagine thats damagebits carry this bitsum value which is 1111 and DMG_BULLET value its 2 which in bitsum its 0010

so the & operator works like this (1111 & 0010) will return this bitsum value 0010 which its 2.

and (damagebits == DMG_BULLET) this condition will only works when its only a bullet damage.

I agree with kristi, you should use bit-wise operators when working with bitsums. Yes, a direct == will work, but it's more proper to check the specific bit(s) you're looking for. If you are checking for multiple bits then you need to use equals on the result of the operation, such as: if ( ( BitSum & ( FLAG_1 | FLAG_2 ) ) == ( FLAG_1 | FLAG_2 ) ). This will ensure the result includes both bits, not only one or the other.

Also, 0100 is 4, 0010 (1<<1) is 2.

So to check for only bullet damage, if ( damagebits & DMG_BULLET ) is good.
