If part of a table exists?

[Sethxi]

I need to have an if statement for if part of a table exists

For example, I have:

local allowedToPickup = {
weapon_mad_deagle = "Deagle"
}

How would I check to see if 'weapon_mad_deagle' exists?

You could change the weapon_mad_deagle to a boolean, then check if it is true or false

You don't need a boolean, if it isn't nil then it should work.

Anyways:
[lua]
if (allowedToPickup.weapon_mad_deagle) then
-- exists
end
[/lua]

[samm5506]

[lua]if allowedToPickup["weapon_mad_deagle"] then
-- do something
end[/lua]

In this example, you're accessing 'weapon_mad_deagle' by its key index in the table. If it didn't exist, the statement would return nil and the condition would be false.

[lua]
local allowedToPickup = { Deagle = "weapon_mad_deagle" }

if table.HasValue( allowedToPickup, "weapon_mad_deagle" ) then
--suck a lolipop
end[/lua]

He's trying to check if the key existed, not the value.
