'''It is required that this message be sent on a regular basis for the simulator to keep the agent in position and in a state that it can be collided with by other agents and objects!''' If the agent is moving and this message is no longer sent, the agent continues its current path indefinitely and ignores physical barriers and gravity is no longer applied. This effect stops the moment an AgentUpdate packet is sent again, and the agent is snapped back to the location where the last AgentUpdate packet was sent. Collision events are triggered on objects the ghosted agent collides with, even though they pass through them. This is often seen when a client crashes during a motion.
'''It is required that this message be sent on a regular basis for the simulator to provide/see updated info about the agent's position and velocity!''' Between receiving agent updates, the sim will continue simulating the agent physically (given the provided control flags) but won't be able to provide the updated position and velocity outside of the physics simulation. This is often seen when a client crashes during a motion.


Far is the distance the viewer can see in meters, it is combined with the viewers FOV to create an interest list on the simulator. Objects outside this distance are not sent to the viewer.

Usage and Notes

Regularly sent to inform the simulator of the state of the viewer, such as where the camera is located, how far it can see, what controls are being pressed and the rotation of various parts of the body(torso and head.)

It is required that this message be sent on a regular basis for the simulator to provide/see updated info about the agent's position and velocity! Between receiving agent updates, the sim will continue simulating the agent physically (given the provided control flags) but won't be able to provide the updated position and velocity outside of the physics simulation. This is often seen when a client crashes during a motion.

Far is the distance the viewer can see in meters, it is combined with the viewers FOV to create an interest list on the simulator. Objects outside this distance are not sent to the viewer.

CameraCenter is the location of the camera in region local coordinates.

CameraAtAxis is the X rotational axis of the camera.(Forward)

CameraLeftAxis is the Y rotational axis of the camera.(Left)

CameraUpAxis is the Z rotational axis of the camera.(Up)
