Runs when the pred runs the command /voplay [NAME_OF_THIS_TRIGGER] and it affects all prey if used like this. However you can also target a single prey by running the command as /voplay [NAME_OF_THIS_TRIGGER] [USERNAME_OF_PREY] instead.
In order to run this trigger, using a trigger named "New Trigger" as an example, the pred must run the command /voplay New_Trigger in order to trigger it. When entering the /voplay command, you will be shown a list of all triggers you can run with it.

If you were to want to target a single prey with this Command Trigger, you would run the command as /voplay New_Trigger John_Doe to target the player John_Doe.
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.
