Need help with a jumping script

Right now I'm just playing around in Unity, and trying out different things. I'm not very good with scripting (yet), so i need help to make my character jump.

The idea is, that the longer you press space (or hold down on a touch screen) the higher the character should jump (with no limits). Holding down longer should make the jump higher.

If anyone could help me making a such script it would be highly appriciated!

 

Here's something to get you started:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class Jump : MonoBehaviour
5. {
6.     private bool jumping;
7.     void FixedUpdate()
8.     {
9.         // Are we standing on something, so we can begin jumping?
10.         bool grounded = Physics2D.Raycast(
11.             (Vector2)transform.position - Vector2.up * .25f, // .25f is the distance from the pivot point, where we should start looking for the floor
12.             -Vector2.up,
13.             0.1f // How far should we look
14.             );
15.  
16.         // Are we standing on something or are we already jumping
17.         if ((grounded || jumping) && Input.GetKey(KeyCode.Space))
18.         {
19.             jumping = true;
20.             rigidbody2D.AddForce(Vector2.up * 25);
21.  
22.             if (rigidbody2D.velocity.y > 200)
23.             {
24.                 Vector2 v = rigidbody2D.velocity;
25.                 v.y = 200;
26.                 rigidbody2D.velocity = v;
27.             }
28.         }
29.         else
30.         {
31.             // If we let go of the jumpbutton, we're not jumping anymore
32.             jumping = false;
33.         }
34.     }
35. }
36.  

 

Thank you very much!
This helped me a lot. Would you mind if I PM you with some questions?

 

Sure, go ahead.
