Getting The Horizontal And Vertical Velocities As Separate Floats?

Hey,
Im trying to make a simple 2d sprite move and jump around. The jumping mechanics are working fine but I cannot implement the movement into the script without making the jumping affect the movement and the movement affect the jumping. Is there a way to get the velocity of the horizontal axis and input it into UNSURE1 and get the velocity of the vertical axis and input it into UNSURE2. I put them as UNSURE so it would be easy to see where i wasnt sure what to add.

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class PlayerJumper : MonoBehaviour {
5.  
6.     private Rigidbody2D rb;
7.  
8.     public float Speed;
9.  
10.     public float Jump_Power;
11.  
12.     // Use this for initialization
13.     void Start () {
14.    
15.         rb = GetComponent<Rigidbody2D> ();
16.  
17.     }
18.    
19.     // Update is called once per frame
20.     void Update () {
21.         print(Input.GetAxisRaw("Vertical"));
22.     //    rb.AddForce (new Vector2 (Input.GetAxis ("Horizontal")*Speed*Time.deltaTime,0));
23.  
24.         if (Input.GetKeyDown (KeyCode.UpArrow)) {
25.             rb.velocity = new Vector2 (UNSURE1, Jump_Power);
26.         } else {
27.             rb.velocity = new Vector2 (Input.GetAxisRaw ("Horizontal") * Speed * Time.deltaTime, UNSURE2);
28.         }
29.     }
30. }
31.  

 

1. Do you mean this?
2. 
   
3. Code (csharp):

   1.  
   2. if (Input.GetKeyDown (KeyCode.UpArrow)) {
   3.        rb.velocity = new Vector2 (rb.velocity.x, Jump_Power);
   4. } else {
   5.        rb.velocity = new Vector2 (Input.GetAxisRaw ("Horizontal") * Speed * Time.deltaTime, rb.velocity.y);
   6. }
   7.  

 

I don't quite know what you are trying to do with your code, but here's how to find the velocity of a rigidbody on a particular axis. You can do the rest

Code (CSharp):

1. float horizontalVelocity = Vector2.Dot(rigidbody.velocity, Vector2.right);
2.  
3. float verticalVelocity = Vector2.Dot(rigidbody.velocity, Vector2.up);

 

Excellent thankyou so much! I had no idea how to find the velocities so to think its as easy as that! xD

 

That's true, but this is mathematically equivalent and much simpler:

Code (CSharp):

1. float horizontalVelocity = rigidbody.velocity.x;
2. float verticalVelocity = rigidbody.velocity.y;

 

Yeah I know, I'm just used to working in 3D where a non world axis might be needed, so it's good to know!
