What Type of Bug are you experiencing?

Devices

Summary

The volume_device does not trigger the AgentEntersEvent when the VolumeShape is set to Sphere.

Additionally, when the volume_device is set to a Box VolumeShape, altering VolumeHeight does not keep the volume centered on the device location. (I’m not sure if this is just a visual representation issue or not)

Steps to Reproduce

Sphere event issue:

  1. Set VolumeShape to Sphere
  2. In verse, subscribe to AgentEntersEvent
  3. Run into the volume with a character
  4. Notice the callback is never invoked
  5. Change VolumeShape to Box
  6. Notice the callback will be invoked as expected

Volume Sizing Issue

  1. Set the VolumeShape to Box
  2. Alter the VolumeHeight to 0.1 from 1.0
  3. Notice the rendering of the volume’s center is below the center
  4. Alter the VolumeHeight to 10
  5. Notice the rendering of the volume’s center is well above the center
  6. Reset the VolumeHeight to 1 and alter VolumeWidth and VolumeDepth, notice that the rendering of the volume center stays centered as expected

Expected Result

Sphere volume_devices should also signal the event when an agent enters the volume.

VolumeHeight modifications should not offset where the volume is.

Observed Result

Sphere volume_devices does not signal the event when an agent enters the volume.

VolumeHeight modifications offset where the volume is.

I may have ran into this using cylinder volumes, but only hearing it from mobile users.
