<desc>Changes the graphics of the object. This affects the display of the given object everywhere in the game: in the landscape, in menus, or on control buttons.</desc>
|
|
<remark>With overlay=0 only the base graphics of an object are changed. The effect corresponds to replacing Graphics.png/Overlay.png in the object <emlink href="definition/index.html">definition</emlink>. Source information from <emlink href="definition/actmap.html">the ActMap</emlink> or <emlink href="definition/defcore.html">DefCore.txt</emlink> will not be modified by this command. So the given coordinates should always point to sensible areas in the bitmap (including SolidMask areas).</remark>
