How do I refer to value retrieved from a dropdown menu?

Unity Engine
1

Thanks in advance, mates.
I know I can use GameObject.Find()getcomponent<>(). = refer to a value in a gameobject…
But it seems that didn’t work with dropdown??

I can see value changed from 0 to 1 to 2 when option1,2,3 is selected respectively, but I don’t know how to refer to this value…

Can anyone please help? I am using C#.

http://docs.unity3d.com/ScriptReference/UI.Dropdown-value.html
that will give you the current selected value

if you need to know what the option is you can use the index value from the above to pull out the appropriate value from the list returned by

Yes…I have read these from script doc …But I still don’t know how can I retrieve that option value (an integer) , and refer to it in other script as an event trigger to trigger some function.

I have browse through the web, and I am testing with addlistener/ sendmessage/ delegate

But If someone can give be some direction will offer me so much help…

Here you add this to your code

public TMP_Dropdown GameType_DropDown;
public string GameType_DropDown_Txt;
public int GameType_DropDown_Int;

string[ ] genres = {“RPG”, “Adventure”, “Simulation”, “Puzzel”, “Quest”, “FPS Shooter”, “3rd Person Shooter”, “Other”, “Turn Based Combat”, “Melee Combat”, “Fantasy”};

GameType_DropDown_Int = GameType_DropDown.value;
for (int i = 0; GameType_DropDown_Int >= i; i++)
{
GameType_DropDown_Txt = genres*;*
