How to use the new Dropdown Menu?

Questions & Answers
1

Im very familiar with the unity 5 UI, especially with buttons, the way buttons work are calling a method… But I don’t seem to find nor have any idea how to call a Method when clicking a certain option in the dropdown.

I have my own method called UseItem() and needs to be used when the first option in the dropdown is clicked. How can I achieve this?
An example code or a reference would be great!
Thanks, in advance :smiley:

Here’s a quick example in C#

using UnityEngine;
using UnityEngine.UI;

public Dropdown myDropdown;

void Start() {
    myDropdown.onValueChanged.AddListener(delegate {
        myDropdownValueChangedHandler(myDropdown);
    });
}

void Destroy() {
    myDropdown.onValueChanged.RemoveAllListeners();
}

private void myDropdownValueChangedHandler(Dropdown target) {
    Debug.Log("selected: "+target.value);
}

public void SetDropdownIndex(int index) {
    myDropdown.value = index;
}

You have to set a callback for the “OnValueChanged” event. That function will get an int as a parameter, which is the index of the selected item in the Dropdown.
