&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;54:503:&amp;#039;&amp;#039;&amp;#039;Sector_ChangeFlags&amp;#039;&amp;#039;&amp;#039;(&amp;#039;&amp;#039;tag&amp;#039;&amp;#039;, &amp;#039;&amp;#039;setflags&amp;#039;&amp;#039;, &amp;#039;&amp;#039;clearflags&amp;#039;&amp;#039;)&lt;br /&gt;

This is a linedef parameterized special. For all sectors with &amp;#039;&amp;#039;tag&amp;#039;&amp;#039;, it adds from &amp;#039;&amp;#039;setflags&amp;#039;&amp;#039; and clears from &amp;#039;&amp;#039;clearflags&amp;#039;&amp;#039; (if previously set).&lt;br /&gt;
&lt;br /&gt;
Each &amp;#039;&amp;#039;...flags&amp;#039;&amp;#039; parameter can be 0 or a sum of the following numbers:&lt;br /&gt;
&lt;br /&gt;
* 1: suppress all sounds coming from sector (including any things acting there)&lt;br /&gt;
* 16: enable Boom-style friction&lt;br /&gt;
* 32: enable Boom-style wind&lt;br /&gt;
* 64: suppress sector mechanical sounds (e.g. door or platform sounds), other things will continue making sounds&lt;br /&gt;
* 128: if sector has damaging floor, make the damage inflicted on players produce splashes&lt;br /&gt;
* 256: if sector has damaging floor, make it remove god mode&lt;br /&gt;
* 512: if sector has damaging floor, make it exit level when a player reaches less than 10 health&lt;br /&gt;
&lt;br /&gt;
Mind that this special exists in ZDoom as well, where it may have more flags. Currently Eternity only supports the flags from this list, and adding more will issue a warning.&lt;/div&gt;</summary>
