Source code (XML)

<parameter items="red=-1,green,blue=5,yellow"/>

NoticeSpaces in the items attribute declaration are taken into account. Thus, items="red=-1, green" shall produce 2 items: "red" and " green"

After loading we'll have switch items with the following values: red = -1, green = 0, blue = 5, yellow = 6.

Source code (C#)

PropertyParameter.SetValue(5); // "blue" shall be selected in the corresponding combobox in the UnigineEditor
PropertyParameter.SetSwitchItem(3); // "yellow" shall be selected in the corresponding combobox in the UnigineEditor (as it is the 3-rd item, starting from 0).

// If "green" item is selected in the UnigineEditor:
PropertyParameter.GetValueInt(); // returns 0, as "green" corresponds to the value of 0.
PropertyParameter.GetSwitchItem() // returns 1, as "green" is the 1-st element in the combobox (starting from 0).
