¶ Pred Movement Trigger
Runs when the pred moves around and targets all prey.
How the trigger works is that it is on a 0.5 second (10 tick) timer. Each loop it compares the current location and the previous location of the pred. If the distance between these two locations is more than or equal to 1 block, then it will trigger the trigger and target all prey.
¶ Targeting Scope
By default, the radius is set to INFINITE and will affect all prey regardless of location. You can however set a 
Position and 
Radius and it will then only affect prey within that radius.
You can make the trigger only affect prey in specific situations using Conditions.
