Munitions seulement pour le Marchand d'armes

Bonjour j'aimerai savoir comment faire en sorte que ce soit seulement le marchand d'armes qui ai accès aux munitions

Voici mon code :

DarkRP.createAmmoType("357", {
name = "M9K 357 ammo",
model = "models/Items/357ammobox.mdl",
price = 150,
amountGiven = 20
})
DarkRP.createAmmoType("ar2", {
name = "Munitions de fusil d'assaut",
model = "models/Items/BoxMRounds.mdl",
price = 200,
amountGiven = 30
})
DarkRP.createAmmoType("buckshot", {
name = "Munitions de fusil à pompe",
model = "models/Items/BoxBuckshot.mdl",
price = 200,
amountGiven = 16
})
DarkRP.createAmmoType("pistol", {
name = "Munitions de pistolet",
model = "models/Items/BoxSRounds.mdl",
price = 90,
amountGiven = 30
})
DarkRP.createAmmoType("smg1", {
name = "Munitions de pistolet mitrailleur",
model = "models/Items/BoxMRounds.mdl",
price = 220,
amountGiven = 60
})
DarkRP.createAmmoType("SniperPenetratedRound", {
name = "Munitions de sniper",
model = "models/Items/BoxMRounds.mdl",
price = 300,
amountGiven = 6
})

Que pourrai-je donc rajouter?

Merci d'avance
