ipairs
Example
Demonstrates how this differs from pairs.
local tbl = { two = 2, one = 1, "alpha", "bravo", [3] = "charlie", [5] = "echo", [6] = "foxtrot" }
print( "pairs:" )
for k, v in pairs( tbl ) do
print( k, v )
end
print( "\nipairs:" )
for k, v in ipairs( tbl ) do
print( k, v )
end
Output:
pairs:
1 alpha
2 bravo
3 charlie
5 echo
6 foxtrot
one 1
two 2
ipairs:
1 alpha
2 bravo
3 charlie
Example
From UpdateUI in undo.lua, this adds the first 32 undo entries to the Undo panel in the spawnmenu.
local NUM = 32
local Count = 0
for k, v in ipairs( ClientUndos ) do
local Item = ComboBox:AddItem( tostring( v.Name ) )
Item.DoClick = function() RunConsoleCommand( "gmod_undonum", tostring( v.Key ) ) end
Count = Count + 1
if ( Count > NUM ) then break end
end
