Point of an intersecting line and plane

Hello,

I am trying to work with moving objects using the mouse.
for doing this I want to calculate the position of the mouse on XY plane.
When the XY coordinates are known i want to move the ball to those XY coordinates.
I have a ball in my world which will be the object of moving.

here is the code so far:
plane = vizshape.addPlane()
plane.setPosition(0,0,ball.getPosition[2])
mouseposition = Camera.main.ScreenPointToRay(Input.mousePosition);

I tried to use viz.intersect but got a lot of errors.
do you guys have any advice.

With kind regards.

You could use the viz.pick command to get the point of intersection between the mouse and the object it is pointing at. Here's an example:

Code:
import viz
import vizact
import vizshape

viz.go()

dojo = viz.add('dojo.osgb')
sphere = vizshape.addSphere(radius=0.1,color=viz.GREEN)
sphere.disable(viz.PICKING)

def moveSphere():
	info = viz.pick(info=True)
	point = info.point
	sphere.setPosition(point)
	
vizact.onupdate(0,moveSphere)
