As a Unity 3D developer, you know how important it is to move your characters and objects in your game or application. In this article, we will explore different methods of moving target in Unity 3D and how to optimize your code for better performance. We will also discuss the use of input devices such as joysticks and controllers to make the movement more intuitive and immersive.
Moving Target with Keyboard Input:
The most basic way to move a target in Unity 3D is by using keyboard input. You can use the arrow keys or WASD keys to move the target in different directions. For example, you can use the ‘W’ key to move forward, the ‘S’ key to move backward, the ‘A’ key to turn left and the ‘D’ key to turn right.

To implement this in your code, you can use the Input class in Unity. The Input class provides access to various input devices such as the keyboard, mouse, and touch screen. You can use the GetAxis() method of the Input class to get the horizontal and vertical axis values from the keyboard.
scss
<h2>float horizontal Input.GetAxis(“Horizontal”);</h2>
<h2>float vertical Input.GetAxis(“Vertical”);</h2>
You can then use these values to move the target in different directions. For example:
scss
transform.position + new Vector3(horizontal * Time.deltaTime * speed, 0, vertical * Time.deltaTime * speed);
Here, speed is a variable that controls how fast the target moves. You can adjust this value to make the movement faster or slower.
Moving Target with Joystick Input:
Joysticks are a popular input device used in gaming and simulation applications. In Unity 3D, you can use joysticks to move your characters and objects in different directions. To implement this, you need to set up the joystick input in your Unity project.
scss
You can do this by creating a new input axis for the joystick and mapping it to the joystick’s horizontal and vertical axes. For example:
css
public InputAxis joystickHorizontal InputAxis.Horizontal;
public InputAxis joystickVertical InputAxis.Vertical;
Once you have set up the input axis, you can use the GetAxis() method to get the horizontal and vertical axis values from the joystick. For example:
scss
float horizontal Input.GetAxisRaw(joystickHorizontal);
float vertical Input.GetAxisRaw(joystickVertical);
You can then use these values to move the target in different directions. For example:
scss
transform.position + new Vector3(horizontal * Time.deltaTime * speed, 0, vertical * Time.deltaTime * speed);
Here, speed is a variable that controls how fast the target moves. You can adjust this value to make the movement faster or slower.
Moving Target with Touch Input:
Touch input is another popular input device used in mobile and tablet applications. In Unity 3D, you can use touch input to move your characters and objects in different directions. To implement this, you need to set up the touch input in your Unity project.
scss
You can do this by creating a new input axis for the touch screen and mapping it to the touch screen’s horizontal and vertical axes. For example:
css
public InputAxis touchScreenHorizontal InputAxis.Horizontal;
public InputAxis touchScreenVertical InputAxis.Vertical;
Once you have set up the input axis, you can use the GetAxis() method to get the horizontal and vertical axis values from the touch screen. For example:
scss
float horizontal Input.GetAxisRaw(touchScreenHorizontal);
float vertical Input.GetAxisRaw(touchScreenVertical);
You can then use these values to move the target in different directions. For example:
scss
transform.position + new Vector3(horizontal * Time.deltaTime * speed, 0, vertical * Time.deltaTime * speed);
Here, speed is a variable that controls how fast the target moves. You can adjust this value to make the movement faster or slower.
Moving Target with Gesture Input:
Gesture input is a type of touch input that involves performing specific gestures on the touch screen. In Unity 3D, you can use gesture input to move your characters and objects in different directions. To implement this, you need to set up the gesture input in your Unity project.
scss
You can do this by creating new input axes for each gesture and mapping them to the corresponding gestures on the touch screen. For example:
css
public InputAxis pinchGesture InputAxis.Horizontal;
public InputAxis swipeGesture InputAxis.Vertical;
Once you have set up the input axes, you can use the GetAxis() method to get the horizontal and vertical axis values from the touch screen. For example:
scss
float pinchValue Input.GetAxisRaw(pinchGesture);
float swipeValue Input.GetAxisRaw(swipeGesture);
You can then use these values to move the target in different directions based on the gesture performed on the touch screen. For example:
scss
if (pinchValue > 0) // Pinch gesture performed, move target to right
{
<h3> transform.position + new Vector3(Time.deltaTime * speed, 0, 0);</h3>
}
<h3>else if (pinchValue < 0) // Pinch gesture performed, move target to left</h3>
{
<h3> transform.position – new Vector3(Time.deltaTime * speed, 0, 0);</h3>
}
Here, speed is a variable that controls how fast the target moves. You can adjust this value to make the movement faster or slower.
Comparing Different Methods of Moving Target in Unity 3D:
Now that we have discussed different methods of moving targets in Unity 3D, let’s compare them based on their performance and usability.
scss
<p>Keyboard input is the simplest and most widely used method of moving targets in Unity 3D. It is easy to implement and provides good control over the movement. However, it may not be as intuitive as other methods such as joystick or gesture input, especially for non-gamers.</p>
<p>Joystick input provides better control over the movement than keyboard input and is more immersive, especially in games that require precision movements. It is also more intuitive than keyboard input, especially for gamers who are used to playing games with joysticks. However, it may not be as widely available as keyboard input, especially on mobile devices.</p>
<p>Touch input is another popular input device used in mobile and tablet applications. In Unity 3D, you can use touch input to move your characters and objects in different directions. To implement this, you need to set up the touch input in your Unity project.</p>
<p>Gesture input is a type of touch input that involves performing specific gestures on the touch screen. In Unity 3D, you can use gesture input to move your characters and objects in different directions. To implement this, you need to set up the gesture input in your Unity project.</p>
