Unity Editor Window (Part 3)

Unity Editor

Hello, Unity Dev’s I am back again with Part 3 of Creating custom editor window in unity.

In today’s blog we will look around: “How to load Textures files from resource folder and create our buttons.”

Step1. Gather some images related to the headers of our sub-toolbars or if you are good at photoshop create some, btw I have zero skills when it comes to photoshop so I am goanna gather images from internet.

Once we have are images ready drag them into respected folder under root folder Resources.

It will look something like this:

Step2. Scripting

 Now we need to create a function which will be called once whenever we will switch from sub-tabs.

Hmmmm, so how to do that!!!

First create a function and name it as per your want’s I have named mine as: “MakeWindow”

Then write down these lines:

Create two variables a list: to store our loaded textures and second an array to load textures files from resource folder.

Line number 110 Loads all the files of Typeof Textured from the respected folder, which is TextureFolder in our code and stores them in _mytextures array.

(Note: _mytextures is of object type which is used whenever we store instances of any files.)

Line No. 112 to 115:

Now we have to convert all our object into Texture2D type and store them into a List.

Line No. 117 to 119:

Next, we need to create buttons as much as we have Texture files in our list.

So, we traverse our list and within our foreach body add an if statement creating button with a parameter of our texture file.

Line No. 107 and 108

OnGUI functions runs at every frame whenever any change happens in unity engine which can cause unnecessary code running so, to avoid that I have added an if statement which checks if list is empty only than create buttons, and once the buttons are created it want run again until we switch between sub-tabs.

Now how to call and from where to call our function with correct parameter.

In our ONGUI() whem we switch between our sub-toolbar which is Line No. 85

We will call our function with parameter.

Out toolbar name / our sub toolbar name

For e.g., Animals/Animal

ToolbarStrings[selection]+ “/” + Sub_folder_toolbar[selection]

ToolbarStrings[selection] if selection is 0 return Animals

ToolbarStrings[selection] if selection is 1 return Buildings

ToolbarStrings[selection] if selection is 0 return Items

ToolbarStrings[selection] if selection is 0 return Staff

Same

Sub_folder_toolbar[selection] if selection is 0 return 1^st folder name respected to Tollbar selected.

Sub_folder_toolbar[selection] if selection is 1 return 2^nd folder name respected to Tollbar selected, and so on..

One last thing add a else statement if our Sub_folders_toolbar.Length > 0

Which means no sub-tabs will be created and it loads our Staff textures.

Step3. Run the Script and we have our Custom editor ready, in which we can select tabs, switch between sub-tabs and have our custom buttons with Textures.

 That’s all for today until next time…..

Happy Coding!!!
