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.

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 ru...

Graphic Raycaster in Unity

Ever wonder how one can click on GUI elements without using any event script on GUI components. On button click, On value change are some event driven functions of GUI components but what if I want to perform any action without using these event driven function.

Next is our global variables Graphical raycaster is used to call the raycaster attach to your canvas, Eventsystem is also used to call the event system of canvas. PointereventData is used to kno...

How to position images/sprites in 2D vs UI.

2D Sprites/Images When working or creating a game in 2d world we have to position are sprites according to camera. Which means if there is a Character and Background in your scene and you may notice that your character is not visible it may be due to wrong positioning. In 2d we set our images according to camera view. Step1. Create a 2d sprite, add image to it and give it a color red and name character. Step2. Duplicate the sprite you created and change its color to green and scale it a bit and name it background. In above scenario we have our camera on 0 in z axis, our character on .1 in z axis than our background is at .2 in z axis. UI sprites/Images Step1. Create a UI image, add image to it and give it a color red and name it character. Step2. Duplicate the Image you created and change its color to green and scale it a bit and name it background. When we are creating our 2d games in UI rather than in 2d we don’t need to position our images related...
