Unity Android Touch Slide

In this article, we will explore how to implement touch slide functionality in Unity for Android. The touch slide feature allows users to interact with the game or application by sliding their finger on the Android device's screen.

Prerequisites

Before diving into the implementation, make sure you have the following:

• Unity installed on your computer.
• Basic knowledge of Unity and C# programming language.
• Android device or emulator to test the application.

Implementation Steps

Step 1: Create a new Unity project

Create a new Unity project or open an existing one.

Step 2: Set up the Android platform

To build and run the project on an Android device, we need to set up the Android platform in Unity. Follow these steps:

1. Go to File -> Build Settings.
2. In the Platform section, select Android.
3. Click on the Switch Platform button to switch to the Android platform.

Step 3: Add touch slide functionality

In this step, we will add touch slide functionality to a game object in Unity.

1. Create a new game object or select an existing one.
2. Attach a script to the game object or open the existing script.
3. In the script, add the following code to handle touch slide:

void Update()
{
    if (Input.touchCount > 0)
    {
        Touch touch = Input.GetTouch(0);

        if (touch.phase == TouchPhase.Moved)
        {
            Vector3 deltaPosition = new Vector3(touch.deltaPosition.x, touch.deltaPosition.y, 0f);
            transform.position += deltaPosition;
        }
    }
}

The above code checks if there is at least one touch detected. If the touch phase is Moved, it retrieves the delta position of the touch and moves the game object accordingly.

Step 4: Build and run the application on Android

1. Connect your Android device to your computer or launch an Android emulator.
2. In Unity, go to File -> Build and Run.
3. Select your target platform as Android.
4. Choose a suitable location to save the APK file.
5. Click on the Build and Run button.

Once the build process is complete, Unity will automatically install the application on your Android device or emulator and run it.

Conclusion

In this tutorial, we have learned how to implement touch slide functionality in Unity for Android. This can be useful for creating interactive games or applications that require user input through touch gestures. You can further enhance the implementation by adding additional features like boundary checks or smooth movement transitions.

Remember to thoroughly test your application on different Android devices and screen sizes to ensure proper functionality.
