what about the onClick?

yeah, you can do that too using SET()
in this case, i just added an onClick behavior to the parent then entered Set("door_vis",0,1)

(and if you prefer, you can use TRUE or FALSE instead of 0 and 1)

so now, in this example, the door can be hidden via the Component Options window's dropdown list OR with the onClick
