5.2.2 The Radar
The colour of the dots shows you what is close to you:
Red living mob
Blue dead mob
Light Blue Teleporter
Orange NPC (Non Player Character :Shopkeeper, Weapons trader, civilian …)
Green other player (alive)
White other player (dead)
Yellow team member, or tamed animal (pet)
Violet society member
Most mobs will attack you if you come too close. That radius differs, but for most you can say:
if they come into the grey area of your radar, they will attack you sooner or later.
Some tougher mobs have a higher aggression radius or higher aggression means they will attack you from higher distance or much earlier, or both.
