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 an

Variable scope in Unity



In today’s blog we are going to learn about the scope of variables, and the different ways a function can be created.
So let’s get started.

Scope of Variables

A variable as we all know is a container which can hold a value or multiple values related to its type. Means a Gameobject type variable can hold any gameobject, a Transform  type variable can hold a transform component of any gameobject, etc.
But some time a variable declared is inaccessible, that’s due to its "scope of life".
A variable declared in a class is said to be a global variable to the function and local to the class where as a variable declared in a function is said to be a local variable of that function.
To understand it more clearly any variable defined within “{}” has its scope of life after the “{” starting curly braches till the “}” ending curly braces.
Let try to understand with a small example.

Step1. Write the following script attach it to any gameobject and hit run.
In this script there is two things to notice one the variable Name which is defined globally and second is the 2 local variables named Myname in each function respectively.


Let’s try something else try to remove the Myname variable declaration, see what happens an error pops up saying:


This is because Myname scope of life starts in function friend1 “{” and ends in function Friend1 “}”.
Whereas Name variable is accessible.
One more tip a local variable when declaired as same name of a global variable in a function will always access the local variable.
To understand more clearly write the following code and run it you will understand what I meant.

Till than Happy Coding!

Write the following code:- This will create a gameobject in the hierarchy with the name specified In ” ”. In our case it’s a cube. As you can see the above script creates a gameobject and add transform component when the object is created as all gameobject have transform component attached to it from the start (e.g. Empty gameobject). In next few lines we added a box collider to our object cube, a mesh renderer and a mesh filter. Save the script and run the project. You will see a gameobject is cr
