HamSandWich function:
Description:
This function gives us info about the moment a player takes damage, when we use it as a forward. The return of the forward is a boolean, if it is set to 1 then the damage will be done if set to 0 then it will not be done!
It also can be used to give damage.
Here I will present how to correctly use this function!
You should use this function when you want to simulate an attack by a entity!
Usage:
PHP Code:
#define OFFSET_LAST_HIT_GROUP 75
#define EXTRAOFFSET_PL_LINUX 5
// plugin_init()
RegisterHam(Ham_TakeDamage, "player", "fw_takedamage")
public fw_takedamage(victim, inflictor, attacker, Float:damage, bits)
{
// Victim is the entity that has been taken damage
// Inflictor is the entity that directly gived damage
// Attacker is the owner of the inflictor
// If Attacker == Inflictor that means that the damage was inflicted by a player (such as gun shot/knife stab)
// Damage the damage
// Bits the type of damage represented in Bitsums
// For grenade damage (In CS) the bits is equal to (1<<24)
// Basically for hooking the he grenade damage is to put this condition
// if (bits & (1<<24))
// For bullet/knife damage (In CS) the bits are equal to (DMG_BULLET | DMG_NEVERGIB)
// Basically for hooking the shot damage is to put this condition
// if (bits & (DMG_BULLET | DMG_NEVERGIB))
// Now the most subtile element is that we can get the last hitgroup where the damage was dealt
new hitgroup = get_pdata_int(victim, OFFSET_LAST_HIT_GROUP, EXTRAOFFSET_PL_LINUX)
}
How to properly execute damage? This is the way to do it!
PHP Code:
#define OFFSET_LAST_HIT_GROUP 75
#define EXTRAOFFSET_PL_LINUX 5
new const Float:hitgroup_multi[] =
{
1.0, // HIT_GENERIC
4.0, // HIT_HEAD
1.0, // HIT_CHEST
1.25, // HIT_STOMACH
1.0, // HIT_LEFTARM
1.0, // HIT_RIGHTARM
0.75, // HIT_LEFTLEG
0.75 // HIT_RIGHTLEG
0.0 // HIT_SHIELD
}
stock Ham_ExecDamage(victim, inflictor, attacker, damage, hitgroup, bits)
{
set_pdata_int(victim, OFFSET_LAST_HIT_GROUP, hitgroup, EXTRAOFFSET_PL_LINUX)
ExecuteHam(Ham_TakeDamage, victim, inflictor, attacker, damage*hitgroup_multi[hitgroup], bits)
}
stock Ham_ExecDamageB(victim, inflictor, attacker, damage, hitgroup, bits)
{
set_pdata_int(victim, OFFSET_LAST_HIT_GROUP, hitgroup, EXTRAOFFSET_PL_LINUX)
ExecuteHamB(Ham_TakeDamage, victim, inflictor, attacker, damage*hitgroup_multi[hitgroup], bits)
}
stock HamRadiusDamage(ent, Float:radius, Float:damage, bits)
{
new target = -1, Float:origin[3]
pev(ent, pev_origin, origin)
while(( target = find_ent_in_sphere(target, origin, radius) ))
{
static Float:o[3]
pev(target, pev_origin, o)
xs_vec_sub(origin, o, o)
// Recheck if the entity is in radius
if (xs_vec_len(o) > radius)
continue
Ham_ExecDamageB(target, ent, pev(ent, pev_owner), damage * (xs_vec_len(o) / radius), HIT_GENERIC, bits)
}
}
