Hi, so I don’t know coding, and I just started using Unity. I’m making a platformer with the Platformer Microgame. So far I have changed textures, audio, controls and other things. Now I want to add some physics to the character. How can I make him wall jump? I guess I would have to edit the script, but I don’t know C# and tutorials on YouTube don’t really use the same jump script, so I’m assuming the wall jump would be for their jump. Any help appreciated. Here’s the Player Controller script (didn’t change anything except for Player speed and jump take off speed:

using System.Collections.Generic;
using UnityEngine;
using Platformer.Gameplay;
using static Platformer.Core.Simulation;
using Platformer.Model;
using Platformer.Core;

/// It is a superset of the AnimationController class, but is inlined to allow for any kind of customisation.
/// </summary>
public class PlayerController : KinematicObject
{
public AudioClip jumpAudio;
public AudioClip respawnAudio;
public AudioClip ouchAudio;
/// <summary>
/// Max horizontal speed of the player.
/// </summary>
public float maxSpeed = 7;
/// <summary>
