Rigidbody2D.linearVelocityX

public float linearVelocityX;

Description

The X component of the linear velocity of the Rigidbody2D in world-units per second.

The linear velocity is specified as a Vector2 with components in the X and Y directions (there is no Z direction in 2D physics).

This property lets you read and write only the X component of the Rigidbody2D.linearVelocity without affecting the Y component of the Rigidbody2D.linearVelocity. This is convenient when dealing with X and Y directions in isolation.

using UnityEngine;

// Ensure that the maximum horizontal speed moving right isn't larger than the configurable value. public class Example : MonoBehaviour { public float MaximumSpeedRight = 2f;

private Rigidbody2D rb;

void Start() { rb = GetComponent<Rigidbody2D>(); }

void FixedUpdate() { // Clamp the horizontal speed. if (rb.linearVelocityX > MaximumSpeedRight) { rb.linearVelocityX = MaximumSpeedRight; } } }
