Change parallax rate at runtime

Hi

Is there a way to change the parallax rate of a specific layer during runtime via an event?

I need my hud to be stationairy (which is no problem).

But, on mouseclick i need to zoom in on the hud, and be able to scroll the hud to mouse X and Y.

For this (in my current understanding) the parallax X&Y of the hud layer needs a setting above 0.

So i im searching for a way to change that parallax rate at runtime.

Like this:

A: On mouse button down set Layer "hud" parallax X rate to 20 & Set parallax Y rate to 20

B: On mouse released set Layer "hud" parallax X Rate to 0 & Set parallax Y Rate to 0

I have searched the forum but havent been succesfull.

The zooming part is allready done.

Thanx in advance for any effort trying to help.

Zooming is more about layer/layoutscale than parallax.

And layerscale/layoutscale can be changed at runtime in the system expressions/actions.

put all the hud object in a family

global number mXStart = 0
global number mYStart = 0
System: On start of layout
  -> hudFamily set xStart to self.X
  -> hudFamily set yStart to self.Y
Mouse: on Left Click
  -> System: set mXStart to mouse.X
  -> System: set mYStart to mouse.Y
Mouse: left button is down
  -> hudFamily set X to self.xStart+mouse.X-mXStart
  -> hudFamily set Y to self.yStart+mouse.Y-mYStart
