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 texture...

Different ways to move object and finding distance between two objects.

In unity one can move a gameobject with few different ways some of them are:

1st way transform.Translate(0, 0, 2);
By writing this piece of line your object will start moving forward in z Direction.

2nd way is using vector 3
transform.position += new Vector3(0, 0, 2);     
By writing this piece of line the gameobject moves same as in above, this line adds 2 on z in every frame of transform.postion.

Note (Transform with capital ‘T’ is used for type declaration like: Transform Player-this will make a player variable of type transform, whereas transform starting with small ‘t’ is used to call the gameobject on which the script is attached or to use the transform property of any gameobject.)
For e.g.
Gameobject Player;
Player.transform.position;

3rd way transform.Translate(Vector3.forward);
By writing this line gameobject on whom script is attach to will start moving forward.

To move a gameobject backward simply write- transform.translate(-Vector3.forward) or transform.translate(Vector3.back);

Same applies for left, right, up and down. Just replace forward from the direction you want to move.This are known as shorthand.

Finding Distance

Now finding distance between two gameobject can come handy in many scenarios.
Suppose we have to create an AI for enemy and want a good AI behavior related to distance between player and enemy say run when distance is more and walk when distance is less hide when in range, etc.

Example- In this example I have created few boxes and a sphere. The yellow line is drawn from sphere to all boxes if and only if they are within the specific distance.

Step1: Scene setup create few cubes and add a tag to all of them with “Objects”.


Create a sphere and add a script to it.

Step2: Write the following code. Attach the script to sphere.

Run the scene.


Try moving any cube back and forth. Tadaaa!! We are done It’s as simple as that.

Open Unity >>Create new project>>create new scene. 1.Creating Gameobject using script Step1.In your scene hierarchy add empty gameobject and name it ScriptManager. Step2. Create a script name it as per your wants, and attach the script to ScriptManager gameobject. Step3. 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...
