SMA 音效編寫<這次簡單點...不過還是不懂>

這是1個殺人吸血的插件呀~ 部份修改了~
SMA碼如下
------------------------------------------------------------------------------------------------

emit_sound 裡有一些設定碼 <能說明一下有什麼用途嗎??>

/* Constants for emit_sound() */
/* Channels */
#define CHAN_AUTO 0
#define CHAN_WEAPON 1
#define CHAN_VOICE 2
#define CHAN_ITEM 3
#define CHAN_BODY 4
#define CHAN_STREAM 5 /* allocate stream channel from the static or dynamic area */
#define CHAN_STATIC 6 /* allocate channel from the static area  */
#define CHAN_NETWORKVOICE_BASE 7 /* voice data coming across the network */
#define CHAN_NETWORKVOICE_END 500 /* network voice data reserves slots (CHAN_NETWORKVOICE_BASE through CHAN_NETWORKVOICE_END). */


/* Attenuation values */
#define ATTN_NONE 0.00
#define ATTN_NORM 0.80
#define ATTN_IDLE 2.00
#define ATTN_STATIC 1.25


/* Pitch values */
#define PITCH_NORM 100 /* non-pitch shifted */
#define PITCH_LOW 95 /* other values are possible - 0-255, where 255 is very high */
#define PITCH_HIGH 120

實質插件問題：
1.如何在這插件裡 設定爆頭擊殺時的音效

2.如何在這插件裡 設定普通擊殺時的音效


~ 以上設定TEST 之後都沒有效果的
