Body Groups

Body Groups

Body Groups are sub meshes of a model that can have changable states. Server code can change the state a model's body groups.

To define a body groups, you need to add a lines in the .qc file.

$bodygroup (name)
{
 studio (modelname)
 ["studio" modelname]
 [blank]
}

For example (a single .mdl could be used for characters with and without glasses):

$bodygroup studio
{
  studio "dude.smd"
}

$bodygroup eyewear
{
  studio "glasses.smd"
  blank
}

This example has two body groups numbered 0 and 1. Group 0 uses a single mesh and group 1 can be a visible glasses model (state 0) or invisible (state 1).

To change a body group's state simply call CBaseAnimating::SetBodygroup( int iGroup, int iValue ) in server code. For example, this would randomly give 1 out of 5 characters glasses:

if ( RandInt( 1, 5 ) == 1 )
  SetBodyGroup( 1, 1 );
else
  SetBodyGroup( 1, 0 );
