error CS0029: Cannot implicitly convert type `float' to `bool'

Hi guys, I am pretty new to unity, so any help would be great. This is my player controller script, and I want my character to jump by using the movement.y

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class PlayerController : MonoBehaviour {
5.  
6.     public float speed = 8;
7.     public float cameraSpeed = 3.5f;
8.     public float jumpHeight = 2;
9.    
10.  
11.     // Use this for initialization
12.     void Start () {
13.        
14.     }
15.    
16.     // Update is called once per frame
17.     void Update () {
18.  
19.         //Roatation
20.         float rotLeftRight = Input.GetAxis ("Mouse X") * cameraSpeed;
21.         transform.Rotate (0, rotLeftRight, 0);
22.  
23.         float rotUpDown = Input.GetAxis ("Mouse Y") * cameraSpeed * -1;
24.         Camera.main.transform.Rotate (rotUpDown, 0, 0);
25.  
26.  
27.         //Movement
28.         float verticalSpeed = Input.GetAxis ("Vertical") * speed;
29.         float horizontalSpeed = Input.GetAxis ("Horizontal") * speed;
30.  
31.         Vector3 movement = new Vector3 (horizontalSpeed, 0f, verticalSpeed);
32.  
33.         movement = transform.rotation * movement;
34.  
35.         CharacterController cc = GetComponent<CharacterController> ();
36.         cc.SimpleMove (movement);
37.  
38.  
39.         //Jumping
40.         if (cc.isGrounded)
41.         {
42.             if (Input.GetAxis ("Jump"))
43.                 movement.y = jumpHeight;
44.         }
45.         cc.Move (movement * Time.deltaTime);
46.     }
47. }
48.  

I keep getting the error:
error CS0029: Cannot implicitly convert type `float' to `bool'

Thanks in advance

 

I assume the error is on line 42 of your posting ?

Code (CSharp):

1.  if(GetAxis("Jump"))

this method returns a float, not a bool.
Do a search for
Input.GetAxis ("Jump")
for some options

 

Ok, thanks.
