UNITY 3D MOVEMENT HOW TO

Basic knowledge of how to code (variables, if/else statements, loops, methods).PrerequisitesДЇirst of all, hereвЂ™s everything you need to know to go through this tutorial successfully: The decision is yours, and whether or not you decide to buy something is completely up to you. Keep in mind that I link these companies and their products because of their quality and not because of the commission I receive from your purchases. Although, I do expect you to have at least some basic knowledge of how the Unity works and basic understanding of programming.ДЄll scripts I made for this tutorial will be available in the Outro section.Дisclosure: Bear in mind that some of the links in this post are affiliate links and if you go through them to make a purchase I will earn a commission. This tutorial is beginner friendly and IвЂ™ll go over everything step-by-step. Every section of this tutorial will include all the code you need for each functionality to work properly. In the next lesson, we will learn about rigidbodies and collisions.In this tutorial IвЂ™ll show you how to make a simple FPS character movement with Unity 3D. You can even adjust the speed in real-time so you do not have to stop and start it all the time. To stop the game, simply press Play again. Try pressing the arrow keys and moving around. Now, click Play and see your first small game in action! This is important because a higher value will make the player move too fast. Now that you are done, change the value of the speed in the GameObjectвЂ™s properties to say 0.8.

Unity will automatically update all scripts once it compiles successfully, so you donвЂ™t have to reattach the script again and again. For the x value, we provide the sum of the objectвЂ™s current position and its speed, effectively adding some amount every frame the key is pressed to its position. The Vector2 takes 2 parameters, which are its x and y values respectively. Next, we are updating the position of our gameObject to a new position defined by creating a new Vector2. The GetAxisRaw method is slightly harder to understand, so weвЂ™ll get back to that later. The Input class is responsible for getting input from the user in the form of key presses, mouse input, controller input, and so on. This method returns -1, 0 or 1 depending on which key the player has pressed on the up/down/left/right arrows. = new Vector2 ( + (h * speed),ДЇirst of all, we make a floating point variable named h (for horizontal), and its value is given by the Input.GetAxisRaw method. To do so, we will add the following code в€’ДЇloat h = Input.GetAxisRaw(вЂњHorizontalвЂќ) If there is a user input, read the directions of input.Д¬hange the position values of the objectвЂ™s transform based on its speed and direction. Let us now consider the objectives for the Update method в€’ Since the speed value is adjustable and need not be changed in code all the time, we can use update() method instead of start(). If you do it correctly, this is what you should see in the GameObjectвЂ™s properties в€’ Next, drag and drop the script from the Assets onto the GameObject. (You can see when it is compiling by the icon in the bottom right corner.) If we save this script without touching the other methods, it should compile in Unity. The variable shows up as a modifiable field inside the editor, so you donвЂ™t have to manually adjust the values in code.

Making a variable public in Unity has a great advantage в€’ Let us create a public float variable named speed. Now, open the script and you should see the same stuff you saw in the last lesson. Create a new script, and name it вЂњMovementвЂќ. This is not restricted to the Transform either all components in Unity have properties, which are accessible through variables in scripting. What is special is that the Transform of a gameObject also shows up as variables in the scripting side of Unity so we can modify it via code. Remember that every GameObject has at least one component в€’ Transform.

This should help us understand the workflow of Unity scripting more easily. In this lesson, we will write code that makes a gameObject move up, down, left and right based on the userвЂ™s input.
