Global.Either#518371

<function name="Either" parent="Global" type="libraryfunc"> <description>An 'if then else'. This is `almost` equivalent to (`condition` and `truevar` or `falsevar`) in Lua. The difference is that if `truevar` evaluates to false, the plain Lua method stated would return `falsevar` regardless of `condition` whilst this function would take `condition` into account.</description> <realm>Shared and Menu</realm> <file line="359-L362">lua/includes/util.lua</file> <args> <arg name="condition" type="any">The condition to check if true or false.</arg> <arg name="truevar" type="any">If the condition isn&#x27;t nil/false, returns this value.</arg> <arg name="truevar" type="any">If the condition isn't nil/false, returns this value.</arg> <arg name="falsevar" type="any">If the condition is nil/false, returns this value.</arg> </args> <rets> <ret name="" type="any">The result.</ret> </rets> </function> <example> <description>The following two `print` statements have identical results.</description> <code> local ply = Entity( 1 ) print( "Player " ..
