How to Smooth Follow Camera 2D in Unity Without Using Smooth Damp
In the world of game development, a smooth camera follow is crucial for creating an immersive experience. In Unity, the default method for achieving this is by using the Smooth Damp function. However, there may be situations where you want to implement a camera follow without relying on Smooth Damp. This article will guide you through the process of creating a smooth 2D camera follow in Unity without using Smooth Damp.
Firstly, let’s understand the basics of camera following in Unity. A camera follow script is responsible for tracking a specific object (usually the player) and adjusting the camera’s position to keep the object centered or follow it closely. To achieve this, we need to calculate the desired camera position and then interpolate between the current and desired positions.
Here’s a step-by-step guide to creating a smooth 2D camera follow in Unity without using Smooth Damp:
1. Create a new C script and name it “SmoothFollowCamera2D.”
2. Open the script and add the following code:
“`csharp
using UnityEngine;
public class SmoothFollowCamera2D : MonoBehaviour
{
public Transform target;
public float smoothSpeed = 0.125f;
public Vector2 offset;
private Vector2 velocity;
void LateUpdate()
{
Vector2 desiredPosition = (Vector2)target.position + offset;
Vector2 smoothedPosition = Vector2.SmoothDamp(transform.position, desiredPosition, ref velocity, smoothSpeed);
transform.position = smoothedPosition;
}
}
“`
3. Save the script and attach it to your camera GameObject.
4. In the Unity Editor, set the “Target” field of the script to the GameObject you want the camera to follow (usually the player).
5. Adjust the “Smooth Speed” parameter to control the smoothness of the camera follow. A higher value will result in a smoother transition, while a lower value will make the camera more responsive.
6. Set the “Offset” parameter to adjust the distance between the camera and the target. You can use this to create a parallax effect or to keep the camera slightly above or below the target.
7. Run the game and observe the camera following the target smoothly without using Smooth Damp.
By following these steps, you can create a smooth 2D camera follow in Unity without relying on the Smooth Damp function. This approach provides more control over the camera’s behavior and can be useful in certain scenarios where you want to fine-tune the camera movement.
