Variables is a powerful feature for `GameItemObjects` to track values, and optionally update `ItemAttributes`.

Add a variable with the "Add" button.

By default, the value of this variable is a float between `0f` and `1f`.

Toggle on "Use Curve" to provide a curve with which to modify the `RangeValue`. Without a curve, the `RangeValue` will always be the same as the `Value`. In the example below, the `Value` is `0.5f`, but the `RangeValue` is `0.75f`.

You can customize the Min and Max values as well. Keep in mind that `RangeValue` will always be at `0f` when the `Value` is at `Min`, and `1f` when the Value is at `Max`.

You can also add one type of `ItemAttributes` as "Variable Attributes". The `ItemAttributes` of this `objectType` will be automatically added and removed based on the `RangeValue`. Based on the values set below, the "New" `ItemAttribute` would be added. The active one will be highlighted in green.
