Using a table with stats to modify shootbullet stats

[GbrosMC]

So I'm making a weapon base that is super simple, and I want to make bullet stat presets depending on the ammotype.

	local AmmoStatMod = {
		[".22"] = {Recoil = 0.5, Num = 1, Force = 2, Damage = 10},
		["9mm"] = {Recoil = 1, Num = 1, Force = 2, Damage = 15},
		[".357"] = {Recoil = 3, Num = 1, Force = 4, Damage = 30},
		[".45"] = {Recoil = 1.5, Num = 1, Force = 3, Damage = 35},
		["50_BMG"] = {Recoil = 5, Num = 1, Force = 6, Damage = 85},
		["7.62mm"] = {Recoil = 1.5, Num = 1, Force = 4, Damage = 25},
		["5.56mm"] = {Recoil = 1.5, Num = 1, Force = 3, Damage = 20},
		[".30-06"] = {Recoil = 1.5, Num = 1, Force = 3, Damage = 25},
		["12_Gauge"] = {Recoil = 2, Num = 9, Force = 2, Damage = 6},
		[".410_Bore"] = {Recoil = 2, Num = 5, Force = 2, Damage = 6}
	}
	for k,v in pairs(AmmoStatMod) do -- k will return something like ".357" instead of a number (On purpose of course), and v returns the table of statistics.
		self.Owner:ViewPunch(Angle(self.Primary.Recoil,math.Rand(-self.Primary.Recoil/5,self.Primary.Recoil/5),0))
		bullet.Num = self.Primary.Num
		bullet.Force = self.Primary.Force
		bullet.Damage = self.Primary.Damage
	end

What I need help with is literally just getting the bullet data to change depending on self.Primary.Ammo, and I don't even know where to start

local tAmmoInfo = AmmoStatMod[self.Primary.Ammo] or {Recoil = 0, Num = 1, Force = 1, Damage = 1}
bullets.Num = tAmmoInfo.Num
-- etc

Had to modify the table values because of the self.Primary.Ammo thing, but everything else is what you said:

	local AmmoStatMod = {
		["simbase_.22"] = {Recoil = 0.5, Num = 1, Force = 2, Damage = 10},
		["simbase_9mm"] = {Recoil = 1, Num = 1, Force = 2, Damage = 15},
		["simbase_.357"] = {Recoil = 3, Num = 1, Force = 4, Damage = 30},
		["simbase_.45"] = {Recoil = 1.5, Num = 1, Force = 3, Damage = 35},
		["simbase_50_BMG"] = {Recoil = 5, Num = 1, Force = 6, Damage = 85},
		["simbase_7.62mm"] = {Recoil = 1.5, Num = 1, Force = 4, Damage = 25},
		["simbase_5.56mm"] = {Recoil = 1.5, Num = 1, Force = 3, Damage = 20},
		["simbase_.30-06"] = {Recoil = 1.5, Num = 1, Force = 3, Damage = 25},
		["simbase_12_Gauge"] = {Recoil = 2, Num = 9, Force = 2, Damage = 6},
		["simbase_.410_Bore"] = {Recoil = 2, Num = 5, Force = 2, Damage = 6}
	}
	for k,v in pairs(AmmoStatMod) do
		local AmmoInfo = AmmoStatMod[self.Primary.Ammo]
		self.Owner:ViewPunch(Angle(-AmmoInfo.Recoil,math.Rand(-AmmoInfo.Recoil/3,AmmoInfo.Recoil/3),0))
		bullet.Num = AmmoInfo.Num
		bullet.Force = AmmoInfo.Force
		bullet.Damage = AmmoInfo.Damage
	end

and then I get:

[ERROR] lua/weapons/simbase_base.lua:73: attempt to index local 'AmmoInfo' (a nil value)

Line 73 is the viewpunch, which is the first function to call AmmoInfo

EDIT:

I'm an idiot, the weapon I was using had the ammo set to simbase_12_gauge instead of simbase_12_Gauge. It works.

You should make it all lower-case, run string.lower on the SWEP.Primary.Ammo key, and add the variable default like I did in the last post.
