TranslucentLine — sets the translucency level for one or more lines.
TranslucentLine (lineid, amount);
TranslucentLine ( lineid, // Line ID of lines to make translucent amount // How translucent the line should be );
When used in ACS, this special's behavior is slightly different than when you place it on a line. From a script, lineid does not change any line's ID. It is only used to specify which lines should have their translucency changed. Placed on a line, TranslucentLine will change its line's ID to lineid if lineid is non-zero.
TranslucentLine only applies to the midtexture of two-sided lines, because only the middle parts of two-sided lines have anything behind them to see.
Create a 50% translucent line:
TranslucentLine (0, 128);
Create a 66% opaque/33% transparent line:
TranslucentLine (0, 169);
Assign this line an ID of 3 and set every line with ID 3 (including this one) to be 75% opaque/25% transparent:
TranslucentLine (3, 191);
