Compiler errors in my code

Questions & Answers

I wrote a script for the player of this game I’m working on in class. It worked fine at first when I just implemented the horizontal movement, but when I added the coding for jumping, I got these error messages:

Assets/Scripts/BoyController.cs(22,22): error CS1502: The best overloaded method match for `UnityEngine.Animator.SetBool(string, bool)’ has some invalid arguments

Assets/Scripts/BoyController.cs(22,22): error CS1503: Argument #2' cannot convert float’ expression to type `bool’

Assets/Scripts/BoyController.cs(40,37): error CS0120: An object reference is required to access non-static member `UnityEngine.Rigidbody2D.AddForce(UnityEngine.Vector2, UnityEngine.ForceMode2D)’

I’m pretty new to scripting, so I’m not entirely sure what these messages are saying. Here’s the script:

using UnityEngine;
using System.Collections;

public class BoyController : MonoBehaviour {
	
	public float maxSpeed = 10f;
	bool facingRight = true;

	Animator anim;

	bool grounded = false;
	public Transform groundCheck;
	float groundRadius = 0.2f;
	public LayerMask whatIsGround;
	public float jumpforce = 700f;

	void Start ()
	{}

	void FixedUpdate ()
	{
		anim.SetBool ("vSpeed", GetComponent<Rigidbody2D>().velocity.y);

		float move = Input.GetAxis ("Horizontal");

		GetComponent<Rigidbody2D>().velocity = new Vector2(move * maxSpeed, GetComponent<Rigidbody2D>().velocity.y);

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


	void Update()
	{
		if(grounded && Input.GetKeyDown(KeyCode.UpArrow))
		{
			anim.SetBool("Ground", false);
			Rigidbody2D.AddForce(new Vector2(0, jumpforce));
		}
	}

	void Flip()
	{
		facingRight = !facingRight;
		Vector3 theScale = transform.localScale;
		theScale.x *= -1;
		transform.localScale = theScale;
	}
}

Does anyone know what I need to fix to get rid of those three error messages? Thanks for any help given.

Line 22, you’re trying to take a float type and shove it into an expected boolean type. Did you mean to use SetFloat and not SetBool?

 anim.SetBool ("vSpeed", GetComponent<Rigidbody2D>().velocity.y); // <-- expects the second paramter that you're getting a component and velocity.y variable to be a float... because you're using SetBool

did you mean:

 anim.SetFloat ("vSpeed", GetComponent<Rigidbody2D>().velocity.y);
