__NOTOC__
This function is useful for '''for''' loops. You don't have to type ''ipairs( getElementsByType( "player" ) )'' but simply ''iterElements( "player" )''. It's very useful if you have many for loops in your code. [[doForAllElements]] has to iterate through elements every time you call 1 function per call but this iterates and what you do to the elements is up to you.

==Syntax==
<syntaxhighlight lang="lua">iterator iterElements( string elementType )</syntaxhighlight>

===Required Arguments===
* '''elementType''': Type of the elements that you want to iterate through.

==Code==
<syntaxhighlight lang="lua">
function iterElements( elementType )
local i = 0;
local tab = getElementsByType( elementType );
return function( )
i = i + 1;
if tab[ i ] then
return i, tab[ i ];
end
end
end
</syntaxhighlight>

==Example==
This example will iterate through all players and vehicles. It will heal the players, give them $1000, send them a message informing them about the action and fix all vehicles when the resource starts.
<syntaxhighlight lang="lua">
addEventHandler( "onResourceStart", getResourceRootElement( ),
function( )
for _, plr in iterElements( "player" ) do
setElementHealth( plr, 100 );
givePlayerMoney( plr, 1000 );
outputChatBox( "You've just been healed and given $1000!", plr );
end

for _, veh in iterElements( "vehicle" ) do
fixVehicle( veh );
end
end
)
