Call

This function is used to call a function from another resource.

The function which you wish to call must first be exported within the resource's meta. For example:

<meta>
	<info author="jbeta" type="script" description="Scoreboard resource" />
	<script src="scoreboard_client.lua" type="client"/>
	<script src="scoreboard_exports.lua" type="server"/>
	
	<script src="scoreboard_http.lua" type="server"/>
	
	<export function="getScoreboardColumns" http="true" />
	<export function="getScoreboardRows" http="true" />
	
	<export function="addScoreboardColumn" type="server"/>
	<export function="removeScoreboardColumn" type="server"/>
	
	<export function="setPlayerScoreboardForced" type="server"/>
	<export function="setScoreboardForced" type="client"/>
</meta>

This enables other resources to call a function from this resource.

Server

This extract shows adding of a "kills" column to the scoreboard resource. This then sets the gameShowKills variable to true, telling the rest of the script to start outputting kills.

function showKills ( option )
	if option == false then
		-- Remove the "kills" column
		gameShowKills = false
		call(getResourceFromName("scoreboard"), "removeScoreboardColumn", "kills")
	elseif option == true then
		-- Add the "kills" column
		gameShowKills = true
		call(getResourceFromName("scoreboard"), "addScoreboardColumn", "kills")
		outputDebugString ( "Showing kills now..." )
	end
end
