I need help working out a C# script with error CS0120
I have recently created the following script to make my character object move in either direction and also flip his sprite when moving left if facing right and visa versa
//variables are being set
public float maxspeed = 10f;
bool facingright = true;
// Use this for initialization
void Start () {
}
// Update is called once per frame
void FixedUpdate ()
{
float move = Input.GetAxis("horizantal");
UnityEngine.Rigidbody2D.velocity = new Vector2(move * maxspeed, UnityEngine.Rigidbody2D.velocity.y);
if (move > 0 && !facingright)
Flip();
else if (move < 0 && facingright)
Flip();
}
//flips the player when they're facing left
void Flip()
{
facingright = !facingright;
Vector3 theScale = transform.localScale;
theScale.x *= -1;
transform.localScale = theScale;
}
}
However i get error CS0120 and I can't figure out how to fix it.
@gooopil To clarify the error is on line 17 of the script, the one that starts with UnityEngine.Rigidbody2D.Velocity
You are trying to modify a property in the class, not on an instance of the class. You need a reference to the instance of Rigidbody you want to modify.
For instance if the script is attached to the same Gameobject you want to move:
Declare a field in your class:
private Rigidbody2D myRigidbody2D;
then in the Start, retrieve the reference:
myRigidbody2D = GetComponent<Rigidbody2D>();
You can then replace your line with
myRigidbody2D.velocity = new Vector2(move * maxspeed, myRigidbody2D.velocity.y);
I'm still getting the same error P.S. I did as you said and here is the new script
//variables are being set
public float maxspeed = 10f;
bool facingright = true;
private Rigidbody2D myRigidbody2D;
// Use this for initialization
void Start () {
myRigidbody2D = GetComponent<Rigidbody2D>();
}
// Update is called once per frame
void FixedUpdate ()
{
float move = Input.GetAxis("horizantal");
myRigidbody2D.velocity = new Vector2(move * maxspeed, UnityEngine.Rigidbody2D.velocity.y);
if (move > 0 && !facingright)
Flip();
else if (move < 0 && facingright)
Flip();
}
//flips the player when they're facing left
void Flip()
{
facingright = !facingright;
Vector3 theScale = transform.localScale;
theScale.x *= -1;
transform.localScale = theScale;
}
}
@gooopil please tell me what lines need to be edited and how.
myRigidbody2D.velocity = new Vector2(move * maxspeed, myRigidbody2D.velocity.y);
@gooopil Sorry about the last thing asking for what needed editing because I figured it out
Thank you for you help as I have now got the game to launch without an error message.
It would be better to ask the question pinpointing where the error is thrown, and indicating the complete error message.
At any rate, this is incorrect:
float move = Input.GetAxis("horizantal");
It should be
float move = Input.GetAxis("Horizontal");
