How to create a drop down menu in editor inspector

Question

Hey everyone,

Now I know there have been quite a few questions like this, but just hear me out!!!!!

Want I want to do, is just have a drop down menu that the user can click on, and then select a value in the inspector where the rest of the variables are.... I don't want it in any extra GUI Window or anything, just next to the rest of the variables for a script in the editor!!!!!!! Here is a link to an image on my website that I snapshotted from unity that basically shows what I'm looking for!!!!!!!!!!!!!!!

Where you see "Dropdown" in my lovely computer hand writing, that is the variable name like the rest of them. When the user clicks on "Var value" I want it to show a dropdown box in which they can then pick from a list of values to assign to the variable. And the other little scribble next to that is where there would be a little arrow most likely to show that it's a drop down menu!!!!!!

It's sort of like a Editor GUI Popup, except I want it in the inspector window next to the rest of the variables!

Any suggestions are welcome!!!!!!!!!!!

Thanks!

-Grady

Hi Grady.

I think what you want is a custom enumeration and a public variable of the type of this enumeration. Unity should display it as a drop down menu, with the elements of the enum as list items. Try:

 enum myEnum // your custom enumeration
 {
    Item1, 
    Item2, 
    Item3
 };

 var dropDown = myEnum.Item1;  // this public var should appear as a drop down

cheers, Vivien

OK, thanks, but how would i use an if() statement to check what the value would be?

Would I go if(dropDown == Item1){ //do stuff here }

it's ok, i just figured it out, i have to use myEnum.Item1 in the if() statement instead of just Item1, but how would i make it so that it has a little downward arrow? I didn't realise that i forgot the link in the post above, so i added it and you might be able to see what i mean!!!!!

EDIT [I realised that the arrow is there, it's just that my screen resolution just cuts off that bit of the screen!!!!!!!]

I also had to go: var dropDown : myEnum; to allow the variable to be set as whatever the value of the enum is!!!!!!!!!!!!!!!!

Thanks for your help!!!!!!!!!!!!!!!!

I read your questions just yet. I've only tried this with C# yet ;) Sry, if the syntax didn't work out completely!

HELP, I did exactly as shown but it says that var can not be used in that context. When I replace it with any datatype, It says it cannot be converted. So what datatype IS myEnum.Item1 ?

This would be the c# version of the code

public enum Orientation{ Left, Right, Top, Bottom }

public Orientation orientation;
