76<hr><a name="_details"></a><h2>Detailed Description</h2>
77Every body can be enabled or disabled. Enabled bodies participate in the simulation, while disabled bodies are turned off and do not get updated during a simulation step. New bodies are always created in the enabled state.<p>
78A disabled body that is connected through a joint to an enabled body will be automatically re-enabled at the next simulation step.<p>
79Disabled bodies do not consume CPU time, therefore to speed up the simulation bodies should be disabled when they come to rest. This can be done automatically with the auto-disable feature.<p>
80If a body has its auto-disable flag turned on, it will automatically disable itself when <ul>
81<li>It has been idle for a given number of simulation steps. </li>
82<li>It has also been idle for a given amount of simulation time.</li>
83</ul>
84A body is considered to be idle when the magnitudes of both its linear average velocity and angular average velocity are below given thresholds. The sample size for the average defaults to one and can be disabled by setting to zero with<p>
85Thus, every body has six auto-disable parameters: an enabled flag, a idle step count, an idle time, linear/angular average velocity thresholds, and the average samples count.<p>
86Newly created bodies get these parameters from world. <hr><h2>Function Documentation</h2>
