Server

In a gamemode, we want a command to change the marker color in the configuration file and remove a deprecated attribute.

config.xml:

<config>
    <markers color="255,100,0" foo="deprecated" />
</config>

Lua code:


function changeConfigMarkerColor(thePlayer, command, r, g, b)
    local config = xmlLoadFile("config.xml")
    local markernode = xmlFindChild(config, "markers", 0)
    xmlNodeSetAttribute(markernode, "color", r .. "," .. g .. "," .. b)
    xmlNodeSetAttribute(markernode, "foo", nil) -- remove 'foo' attribute
    xmlSaveFile(config)
    xmlUnloadFile(config)
end
addCommandHandler("markercolor", changeConfigMarkerColor)
