How To: Make a perfect NPC

From CHR Engine:

PHP Code:

stock entity_set_aim(ent,const Float:origin2[3],bone=0)
{
    if(!pev_valid(ent))
        return 0;

    static Float:origin[3]
    origin[0] = origin2[0]
    origin[1] = origin2[1]
    origin[2] = origin2[2]

    static Float:ent_origin[3], Float:angles[3]

    if(bone)
        engfunc(EngFunc_GetBonePosition,ent,bone,ent_origin,angles)
    else
        pev(ent,pev_origin,ent_origin)

    origin[0] -= ent_origin[0]
    origin[1] -= ent_origin[1]
    origin[2] -= ent_origin[2]

    static Float:v_length
    v_length = vector_length(origin)

    static Float:aim_vector[3]
    aim_vector[0] = origin[0] / v_length
    aim_vector[1] = origin[1] / v_length
    aim_vector[2] = origin[2] / v_length

    static Float:new_angles[3]
    vector_to_angle(aim_vector,new_angles)

    new_angles[0] *= -1

    if(new_angles[1]>180.0) new_angles[1] -= 360
    if(new_angles[1]<-180.0) new_angles[1] += 360
    if(new_angles[1]==180.0 || new_angles[1]==-180.0) new_angles[1]=-179.999999

    set_pev(ent,pev_angles,new_angles)
    set_pev(ent,pev_fixangle,1)

    return 1;
}

Thank GHW_Chronic, he made it. =)

And how do you do the same, just with speed, I mean that npc will turn little by little to the aim origin.
