Environment Variables #

This is a guide on how to reference environment variables in MMDAgent-EX files, as well as the environment variables that affect the operation of MMDAgent-EX.

Referencing Environment Variables in .mdf Files #

Environment variables can be referenced with %ENV{name}. If the specified name of the environment variable is not defined, it will be blank.

Playback Command play for AUDIO_START #

In Ubuntu and macOS, the “play” command from sox is used for sound file playback with the AUDIO_START message. Playback is initiated from within MMDAgent-EX using the -q option as follows:

play -q file.mp3

First, the play command is searched for in the PATH. If there is an error because play is not found in the path, it searches in the order of /opt/homebrew/bin/play, /usr/local/bin/play, /usr/bin/play, and the first one found is used.

If you want to specify a different sound playback command, specify it with the MMDAGENT_AUDIO_PLAY_COMMAND environment variable.

Content Folder #

The content folder is a workspace that stores downloaded content and history information. By default, it is “MMDAgent-Contents” directly under the desktop. However, you can specify a different location using the MMDAgentContentDir environment variable.
