ClientThis example shows how to toggle a message on/off a screen with a command.
function drawText() -- A function to draw the text we want dxDrawText(text, 10,100) -- creates a dx text 10 pixels from left, 100 from top of the screen end function doText(command, ...) if command == "starttext" then -- if player wrote /starttext text = table.concat({...}," ") -- then we retrieve the text addEventHandler("onClientRender", getRootElement(), drawText) -- and since addEventHandler and removeEventHandler's syntax is the same, we just define the function we use later elseif command == "stoptext" then removeEventHandler("onClientRender", getRootElement(), drawText) -- this time we use removeEventHandler end end addCommandHandler("starttext", doText) -- add two command handlers to doText function addCommandHandler("stoptext", doText)
