Struggling with movement for a 2D side scroller

Questions & Answers
1

Hello, I am making a 2D sidescrolling fighter game but I am having some problems with creating a C# script for moving the player character left and right using the arrow keys. I’ve tried looking at a lot of tutorials and help sites but most of what I find is outdated and so when I’ve tried following them, I’ve just hit dead ends. I came here because I really don’t know where else I can ask this - thanks in advance to anyone who can help me out here!

There are multiple ways in which you can move the player, This is how I do it in a lot of my 2D games:

if (Input.GetKey(KeyCode.A))
        {
            transform.position = transform.position += transform.right * -moveSpeed * Time.deltaTime;
        }

if (Input.GetKey(KeyCode.D))
        { 
            transform.position = transform.position += transform.right * moveSpeed * Time.deltaTime;
        }

That is just simply checking if the player is pressing either the A or D key and then it will move the player in the right direction times by it’s moveSpeed which I assign in the inspector. If you want to use the arrow keys to move the player instead then you just got to change KeyCode.A to KeyCode.LeftArrow and KeyCode.D to KeyCode.RightArrow.

Also make sure to run all this in the Update method so it’s checking for input every frame.

Hope this helps and good luck with your game

//movement variable

bool facingRight;

public float maxSpeed;

 float move = Input.GetAxis("Horizontal");//Edit>Project setting>Input check about Horizontal if you dont know about t//
 myAnim.SetFloat("speed", Mathf.Abs(move)); //playing the animation//

 myRB.velocity = new Vector2(move * maxSpeed, myRB.velocity.y);

 if (move > 0 && !facingRight)
 {
     flip();
 }
 else if (move < 0 && facingRight)
 {
     flip();
 }

}

void flip()

{

 facingRight = !facingRight;
 Vector2 theScale = transform.localScale;
 theScale.x *= -1;
 transform.localScale = theScale;

}
