Creating Camera Shake Effect in Unity

Camera shake is a powerful tool used in game development to add impact and excitement to various events such as explosions, collisions, or dramatic moments. In this tutorial, you'll learn how to create a simple yet effective camera shake script that you can easily integrate into your Unity projects. By following along, you'll be able to enhance the visual feedback in your games and create immersive experiences for your players.

Step 1: Set Up Your Unity Project

  • Open Unity and create a new 2D or 3D project. Ensure you have a main camera in your scene.

Step 2: Import Camera Shake Script

  • If you don't have a camera shake script, you can create one or find a free one online. For simplicity, let's assume you have a script named 'CameraShake.cs'.

Step 3: Attach Script to Camera

  • Drag and drop the 'CameraShake.cs' script onto your main camera game object in the Unity Editor.

Step 4: Trigger the Shake Effect

  • In your game code (e.g., when an explosion occurs), call a function to trigger the camera shake effect. For example:
// Example code to trigger camera shake
void OnTriggerEnter(Collider other)
    if (other.CompareTag("Explosion"))
        Camera.main.GetComponent<CameraShake>().ShakeCamera(0.5f, 0.1f); // Duration: 0.5 seconds, Intensity: 0.1

Step 5: Implement Camera Shake Function

  • In your 'CameraShake.cs' script, implement a function to shake the camera. Here's a basic example:


using UnityEngine;

public class CameraShake : MonoBehaviour
    private Vector3 originalPosition;

    // Shake the camera with given duration and intensity
    public void ShakeCamera(float duration, float intensity)
        originalPosition = transform.localPosition;
        InvokeRepeating("DoShake", 0, 0.01f);
        Invoke("StopShake", duration);

    // Perform the shake effect
    private void DoShake()
        float offsetX = Random.Range(-0.1f, 0.1f);
        float offsetY = Random.Range(-0.1f, 0.1f);
        transform.localPosition = originalPosition + new Vector3(offsetX, offsetY, 0);

    // Stop the shake effect and reset camera position
    private void StopShake()
        transform.localPosition = originalPosition;

Step 6: Test and Adjust

  • Play your game in the Unity Editor and test the camera shake effect. Adjust the duration and intensity parameters in the 'ShakeCamera' function to achieve the desired effect.

Step 7: Documentation

  • Document the usage of the camera shake script in your project for future reference and for other team members working on the project.


By following these steps, you can easily implement a camera shake effect in your Unity game using the provided code example. Experiment with different parameters to fine-tune the effect to fit your game's style.
