IterElements

From Multi Theft Auto: Wiki

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 through elements and what you do to/with the elements is up to you.

Syntax

iterator iterElements( string elementType )

Required Arguments

elementType: Type of the elements that you want to iterate through.

Code

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

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.

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
)
