这种_Rank.gsc怎么添加装备

giveSMG()
{
self clearPerks();
self takeAllWeapons();
self giveWeapon("knife_mp");
self GiveMaxAmmo("knife_mp");
self giveWeapon("crossbow_explosive_mp");
self GiveMaxAmmo("crossbow_explosive_mp");
self giveWeapon("commando_elbit_dualclip_silencer_mp");
self GiveMaxAmmo("commando_elbit_dualclip_silencer_mp");
self giveWeapon("frag_grenade_mp");
self giveWeapon("nightingale_mp");
wait .1;
self switchToWeapon("commando_elbit_dualclip_silencer_mp");

self setPerk("specialty_unlimitedsprint");
self setPerk("specialty_quieter");
self setPerk("specialty_bulletdamage");
self setPerk("specialty_movefaster");

self.killstreak[0] = "killstreak_rcbomb";
self.killstreak[1] = "killstreak_auto_turret_drop";
self.killstreak[2] = "killstreak_dogs";
self freezeControls(false);



比如我想添加炸药包(satchel_charge_mp)
用 self giveWeapon("satchel_charge_mp");指令不能正确的添加.
谁知到该怎么改.谢谢了
