PlayerTrails This plugin adds an interesting and appealing game mechanic to your server. All of the players, while walking or running will leave a trace of particles behind them. These particles will automatically vanish after a given amount of minutes (config.yml). The purpose of this plugin is to make it so trails may be followed and players will need to be more cautious of their position and static bases. The colour of the particle will depend on the player coordinates height (red to bright yellow).
I will add new ways for players to avoid traces being left behind, for now the only way is sneaking.
