In an object’s property panel you will find a toggle for simulated. If set simulated is false, the object cannot be moved by physics or grabbed by a player. If a player is holding an object when set simulated is set to false, the object is released from the player’s hand.
Set an object’s simulation to the boolean true or false.
SET TRIGGER DETECTION precedes this tutorial
Example 1: Disable simulation with an event
The when trigger is exited by object we set simulated on the obj to disable its movement. You can imagine this event affecting a robot that mistakenly leaves its designated area.
