Synopsis

getNextFreeMultiIndexForSource

This returns the next multi index that's available for the given source plug. This is the same as getNextFreeMultiIndex, but we assume the attr is a source plug, not destination. This command is useful when connecting nodes where one wishes to connect to the first available multi on a node, i.e. the first element that is not already connected.

Return value

None

Arguments

Variable Name Variable Type Description
$attr string the name of the multi attribute to get the free index for
$start int the first index to check from ( use zero if last index is not known )

MEL examples

  createNode nucleus;
  int $index = getNextFreeMultiIndexForSource( "nucleus1.outputObjects", 0 );
