Lesson Three Walkthrough
In the previous lesson, you practised linking activatables up to public methods that you wrote in scripts. This is a common pattern in ViRSE (and Unity in general), and in this lesson you’ll do the same with adjustables!
When working with adjustables, you need to declare functions that take a float parameter to capture the value that the adjustable is currently set to.
Defining a function to be invoked by the adjustable, which takes a float as a parameter
As with activatables, drag and drop the gameobject containing your script into the appropriate event on the adjustable inspector. Then, select your function to tell the adjustable to invoke that function when the event occurs, passing the float value.
Our Adjustable, configured to invoke our public function
You will notice that there are two types of OnValueAdjusted events in the adjustable - one called OnValueAdjusted and another called OnValueAdjustedBasic. ****The first method takes both the adjustable value float and a string which contains the ID of the player interacting with the adjustable, which can be useful in some multiplayer contexts. The basic method uses only the adjustable value float parameter.
In this exercise you’ll link your methods to the adjustable’s OnValueAdjustedBasic event, rather than OnValueAdjusted, because the game you’re building won’t make use of the player ID string.

Similar to GrabActivatables, GrabAdjustables are components that can be attached to Gameobjects that already contain a FreeGrabbable to allow for hand-held adjustable functionality. In VR mode, adjusting is done with the thumbstick on the VR controller. In non-VR mode, the mouse’s scroll wheel is used instead.
