how to add a jump/double jump to a free form directional mecanim controller with scripting

Please help just stuck on this part on my script for my mecanim controller I need to add a jump / double jump to this

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class Movement : MonoBehaviour {
5.  
6.     Animator anim;
7.  
8.     bool grounded = false;
9.     public Transform groundCheck;
10.     float groundRadius = 0.2f;
11.     public LayerMask whatIsGround;
12.  
13.  
14.     // Use this for initialization
15.     void Start () {
16.      
17.         anim = GetComponent<Animator> ();
18.     }
19.  
20.     void FixedUpdate (){
21.  
22.         grounded = Physics2D.OverlapCircle (groundCheck.position, groundRadius, whatIsGround);
23.         anim.SetBool ("Ground", grounded);
24.  
25.     }
26.  
27.     // Update is called once per frame
28.     void Update () {
29.  
30.         float input_x = Input.GetAxisRaw ("Horizontal");
31.         float input_z = Input.GetAxisRaw ("Vertical");
32.  
33.         bool IsWalking = (Mathf.Abs (input_x) + Mathf.Abs (input_z)) >0;
34.         anim.SetBool ("IsWalking", IsWalking);
35.         if (IsWalking)
36.         {
37.             anim.SetFloat ("x", input_x);
38.             anim.SetFloat ("z", input_z);
39.  
40.             transform.position += new Vector3(input_x, 0f, input_z).normalized * Time.deltaTime;
41.             if (grounded && Input.GetKeyDown (KeyCode.Space))
42.             {
43.                 anim.SetBool ("Ground",false);
44.             }
45.         }
46.     }
47. }

Any suggestions?

 

try this, it works perfectly for 2D games, but it should work for 3D as well.

You'll need to create a float called "jumpHeight" to control... well I think it's pretty obvious xD.

Code (CSharp):

1. if (grounded && Input.GetKeyDown(Keycode.Space))
2. {
3.      anim.SetBool("Ground", false);
4.      GetComponent<Rigidbody>().AddForce(Vector3.up * jumpHeight, ForceMode.Impulse);
5. }

 

OK ill give t a shot

 

Let me know if it works!

 

Also by the way It's for my 3d game so I'm trying to figure this out if you have another method I'm all ears

 

Did that method not work?

 

nah it gave me some errors
here:
error CS1503: Argument `#1' cannot convert `object' expression to type `UnityEngine.Vector3'
The best overloaded method match for `UnityEngine.Rigidbody.AddForce(UnityEngine.Vector3, UnityEngine.ForceMode)' has some invalid arguments
