Player.GetAmmoCount() returns 0 for some weapons, but works for others?

[bl00db4th7]

Hi. I'm working on a HUD and I've run into a small issue I can't seem to find a solution to.

On some weapons, GetAmmoCount returns the number of bullets remaining total. It does it's job. On other weapons (even some weapons that use the [i]same ammo type as a weapon that works[/i]) it refuses to return anything other than 0. My current workaround is to just display the weapon:Clip1() and simply say "fuck off" to the glitchy ammo count, but I would much prefer to display that.

Here's my current code:
[lua] local AmmoText = "Unlimited"
local ActiveWep = LocalPlayer():GetActiveWeapon()
if ValidEntity( ActiveWep ) then
local AmmoMax = LocalPlayer():GetAmmoCount( tostring( ActiveWep:GetPrimaryAmmoType() ) )
local AmmoCurrent = ActiveWep:Clip1()
AmmoText = tostring( AmmoCurrent ) .. " / " .. tostring( AmmoMax )
if AmmoMax == -1 then
AmmoText = "Unlimited"
elseif AmmoCurrent == -1 then
AmmoText = "Unlimited"
end
else
AmmoText = "Unlimited"
end
if tostring( AmmoText ) != "Unlimited" then
draw.WordBox( 12, 15, ScrH() - 195, AmmoText, "HUDNumber3", Color( 20, 20, 20, 180 ), Color( 20, 180, 20, 255 ) )
end[/lua]

Any suggestions would be appreciated.
