Patch 175.0 added a new menu for Dino-Whistle-Commands. You can access it by keeping the “T”-key pressed (or the “Whistle Follow Me”-key, should you have reassigned it).
The menu provides access to a diverse set of whistling options for your dinosaurs. Obiously they only work for tamed dinos (if you haven’t tamed one yet, here‘s a tutorial).
|Whistle Follow All||All Dinosaurs in a certain radius will follow you.|
|Whistle Follow One||The Dinosaur you’re looking at will follow you.|
|Whistle Stop All||All Dinosaurs in a certain radius will stop.|
|Whistle Stop One||The Dinosaur you’re looking at will stop.|
|Whistle Aggressive||All Dinosaurs in a certain radius will get aggressive. That means, they’re going to attack all people and animals that aren’t a member of your tribe.|
|Whistle Neutral||All Dinosaurs in a certain radius will get neutral. That means, they’re going to abort their current attacks, but will still defend themselves should they be under attack.|
Keep in mind that the radius of the whistles is limited.
