AudioMixer.FindMatchingGroups

반환

AudioMixerGroup[] Groups in the mixer whose paths match the specified search path.

설명

Connected groups in the mixer form a path from the mixer's master group to the leaves. This path has the format Master Group/Child of Master Group/Grandchild of Master Group, and so on. For example, in the hierarchy below, the group DROPS has the path Master/WATER/DROPS. To return only the group called DROPS, enter DROPS. The substring Master/AMBIENCE returns three groups, AMBIENCE/CROWD, AMBIENCE/ROAD, and AMBIENCE. The substring /R would return both ROAD and RIVER.

        // Will find all groups with a path containing the substring "Master/AMBIENCE"
        // In the below example, this matches three groups "Master/AMBIENCE/CROWD", "Master/AMBIENCE/ROAD", and "Master/AMBIENCE".
