"There is a direct correlation between skill and the amount of time a player looks at the minimap."
-paraphrased from Day[9]
This is an open source training tool that will help the user develop a habit of looking at the mini map. This plugin will play an audio file reminding the user to check the minimap. It will play only during a game (or repeatedly if you want). You can have specify the delay or have a random (uniformlly or normally distributed) delay chosen from an interval you provide. You can modify settings on the fly so if you need to alt-tab out of game to adjust the volume, mute, change intervals, or change mode you can without needing to restart anything.
There are a few sample sounds in the plugin folder.
If anyone wants to modify this and redistribute it, go ahead, but credit would be nice.
Enjoy,
