Hi Hetal,
Here is the documentation on using a mouse click as a callback:
https://docs.worldviz.com/vizard/lat...ighlight=mouse
Then you could use avatar.getPosition() to query the avatar's position from that mouse click callback
https://docs.worldviz.com/vizard/lat...ht=getposition
You can also try turning on collision with the environment for the avatar to move over the terrain correctly?

Best,
