Fakemeta function:

PHP Code:

EngFunc_GetBonePosition 


Description:
The function allows to get the bone positions of an entity. This is best used on getting specific player origin points.

These are the bones that a player has.

Usage:

PHP Code:

// ENTITY is the player entity id
// BONE_NUMBER you have to choose from the list above
// bone_origin[3] is the vector where we save the bone origin
// bone_angles[3] the vector that holds the angles of the bone.
engfunc(EngFunc_GetBonePosition, ENTITY, BONE_NUMBER, Float:bone_origin[3], Float:bone_angles[3]) 


Useful Stocks:
These stocks are made for CS/CZ you need to port them to other mods.

This gets the hitgroup of the bone.

PHP Code:

#define BONE_HIT_HEAD              8
#define BONE_HIT_CHEST             6
#define BONE_HIT_STOMACH         4
#define BONE_HIT_LEFTARM        24
#define BONE_HIT_RIGHTARM        39
#define BONE_HIT_LEFTLEG        48
#define BONE_HIT_RIGHTLEG        54
#define HEAD_NECK                40
#define BONE_L_BUTT                41
#define BONE_R_BUTT                42

stock get_bone_hitgroup(number)
{
    switch (number)
    {
        case HEAD_NECK:
        {
            return HIT_HEAD
        }
        case BONE_L_BUTT:
        {
            return HIT_LEFTLEG
        }
        case BONE_R_BUTT:
        {
            return HIT_RIGHTLEG
        }
    }
    
    if (1 <= number <= BONE_HIT_STOMACH)
        return HIT_STOMACH
    
    if (BONE_HIT_STOMACH < number <= BONE_HIT_CHEST)
        return HIT_CHEST
    
    if (BONE_HIT_CHEST < number <= BONE_HIT_HEAD)
        return HIT_HEAD
    
    if (BONE_HIT_HEAD < number <= BONE_HIT_LEFTARM)
        return HIT_LEFTARM
    
    if (BONE_HIT_LEFTARM < number <= BONE_HIT_RIGHTARM)
        return HIT_RIGHTARM
    
    if (BONE_HIT_RIGHTARM < number <= BONE_HIT_LEFTLEG)
        return HIT_LEFTLEG
    
    if (BONE_HIT_LEFTLEG < number <= BONE_HIT_RIGHTLEG)
        return HIT_RIGHTLEG
    
    return HIT_GENERIC
} 


This gets the closest bone to the gunshot [Use this in FM_TraceLine and Ham_TraceAttack

PHP Code:

#define DISTANCE_CLEAR_HIT        2.0

stock find_closest_bone_to_gunshot(victim, Float:endtrace[3])
{
    new Float:angles[3], Float:origin[3], Float:dist = 9999999.99, Float:curorigin[3], bone_nr
    for (new i=1;i<=54;i++)
    {
        // Get the bone position
        engfunc(EngFunc_GetBonePosition, victim, i, curorigin, angles)
        // Calculate the distance vector
        xs_vec_sub(curorigin, endtrace, angles)
        
        // If this is smaller than the last small distance remember the value!
        if (xs_vec_len(angles) <= dist)
        {
            origin = curorigin
            dist = xs_vec_len(angles)
            bone_nr = i
        }
        
        // If distance is smaller than CLEARHIT! Break (We accept the last value!)
        if (dist <= DISTANCE_CLEAR_HIT)
        {
            break
        }
    }
    
    // Return the bone
    return bone_nr
}
