Set Screen Boundaries for 2D Player

Set Screen Boundaries for 2D Player

// This script ensures that the player will not be able to move outside the ranges set by the min and max floats on the x and y axis.
// If you need your screen boundaries to be symetrical, you could have less code below by replacing the four variables with
// only two instead (eg. boundaryX, boundaryY). Then in the Mathf.Clamp statements,
// you would simply use (transform.position.x, -boundaryX, boundaryX) and (transform.position.y, -boundaryY, boundaryY)

using UnityEngine;

public class ScreenBoundaries : MonoBehaviour
{
    float minX = -9f;
    float maxX = 9f;
    float minY = -5f;
    float maxY = 5f;

    void Update()
    {
        Vector2 playerPos = new Vector2(transform.position.x, transform.position.y);
        playerPos.x = Mathf.Clamp(transform.position.x, minX, maxX);
        playerPos.y = Mathf.Clamp(transform.position.y, minY, maxY);
        transform.position = playerPos;
