This example creates a label when an element is clicked, the label displays in the position of the element telling you what kind of element you have clicked. It hides after 5 seconds.
local myLabel = guiCreateLabel ( 0, 0, 1, 1, "", true ) function addLabelOnClick ( button, state, absoluteX, absoluteY, worldX, worldY, worldZ, clickedElement ) --if an element was clicked on screen if ( clickedElement ) then --retreive the element type local elementType = getElementType ( clickedElement ) --change the label text to that element type guiSetText ( myLabel, elementType ) --and place it in the position of where the element is guiSetPosition ( myLabel, absoluteX, absoluteY, false ) --hide the text by passing an empty string 5 seconds later setTimer ( guiSetText, 5000, 1, myLabel, "" ) end end addEventHandler ( "onClientClick", getRootElement(), addLabelOnClick )
