+Object 7/7/8 is a placeholder for force bridges that have not been activated yet. These objects are invisible and are made to force bridges with the use of trigger action 24.
+
+Force bridges of type 7/7/9 differ from the typical ones (7/7/7) in having a default height of zero and no animation when switched from type 8. They furthermore need a size explicitly set.
+
+The engine supports several different values for ```Colour```. Used values are ```0x00``` for red and ```0xFE``` for green.
+
+> Not all 256 colour possibilities have been tested, many resulted in dark red tones or solid colours. Usable variants were found from ```0xF7``` and above.
