I can't get my sprite using the rigidbody physics to move.

I have a rigidbody2d on but my still doesn't move or rotate.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public abstract class SpaceCharacter : MonoBehaviour
6. {
7.  
8.     [SerializeField]
9.     private float speed;
10.     [SerializeField]
11.     private float turnSpeed;
12.  
13.     protected Vector3 vertical;
14.     protected Vector3 horizontal;
15.  
16.     private Rigidbody2D myRigidbody;
17.  
18.     // Use this for initialization
19.     protected virtual void Start()
20.     {
21.         myRigidbody = GetComponent<Rigidbody2D>();
22.     }
23.  
24.     // Update is called once per frame
25.     protected virtual void Update()
26.     {
27.  
28.     }
29.  
30.     private void FixedUpdate()
31.     {
32.         Move();
33.     }
34.  
35.     public void Move()
36.     {
37.         myRigidbody.velocity = vertical.normalized * speed;
38.         myRigidbody.velocity = horizontal.normalized * turnSpeed;
39.     }
40. }

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class SpacePlayer : SpaceCharacter
6. {
7.     [SerializeField]
8.     private SpaceStat health;
9.  
10.     [SerializeField]
11.     private SpaceStat mana;
12.  
13.     private float initHealth = 100;
14.  
15.     private float initMana = 50;
16.  
17.     protected override void Start()
18.     {
19.  
20.         health.Initialize(initHealth, initHealth);
21.         mana.Initialize(initMana, initMana);
22.  
23.         base.Start();
24.     }
25.  
26.     // Update is called once per frame
27.     protected override void Update()
28.     {
29.         GetInput();
30.         base.Update();
31.     }
32.  
33.     private void GetInput()
34.     {
35.         vertical = Vector3.zero;
36.         horizontal = Vector3.zero;
37.  
38.         ///This Is Used For Debugging Only
39.         ///
40.         if (Input.GetKeyDown(KeyCode.I))
41.         {
42.             health.MyCurrentValue -= 10;
43.             mana.MyCurrentValue -= 10;
44.         }
45.         if (Input.GetKeyDown(KeyCode.O))
46.         {
47.             health.MyCurrentValue += 10;
48.             mana.MyCurrentValue += 10;
49.         }
50.  
51.  
52.         if (Input.GetKey(KeyCode.W))
53.         {
54.             vertical += Vector3.up;
55.         }
56.         if (Input.GetKey(KeyCode.A))
57.         {
58.             horizontal += Vector3.back;
59.         }
60.         if (Input.GetKey(KeyCode.S))
61.         {
62.             vertical += Vector3.down;
63.         }
64.         if (Input.GetKey(KeyCode.D))
65.         {
66.             horizontal += Vector3.forward;
67.         }
68.     }
69. }

 

The problem is I can't move or rotate my 2dplayer.

 

What happens if you make FixedUpdate() virtual in the base class and override it in the child class and call base.FixedUpdate()?

 

Like this?It doesn't work.

Code (CSharp):

1. private virtual void FixedUpdate()
2.     {
3.         Move();
4.     }

 

I don't know how to fix the problem.The game works I just can't move the player.

 

this was my original script.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public abstract class SpaceCharacter : MonoBehaviour
6. {
7.  
8.     [SerializeField]
9.     private float speed;
10.     [SerializeField]
11.     private float turnSpeed;
12.  
13.     protected Vector3 vertical;
14.     protected Vector3 horizontal;
15.  
16.     // Use this for initialization
17.     protected virtual void Start()
18.     {
19.  
20.     }
21.  
22.     // Update is called once per frame
23.     protected virtual void Update()
24.     {
25.         Move();
26.     }
27.     public void Move()
28.     {
29.         transform.Translate(vertical * Time.deltaTime * speed);
30.         transform.Rotate(horizontal * Time.deltaTime * turnSpeed);
31.     }
32. }
33.  

 

Well, this piece of code is setting the velocity twice (no rotation is included):
(the second one means the first is ignored, of course)

Code (csharp):

1.  
2. public void Move()
3.     {
4.         myRigidbody.velocity = vertical.normalized * speed;
5.         myRigidbody.velocity = horizontal.normalized * turnSpeed;
6.     }

Did you want angularVelocity for one? Note, you could also simply set the rotation, too, or use the transform.Rotate -- just depends what you want.

Okay, I just re-read the code. You're checking for Input in Update; now, for some of the 'KeyDown' checks, that's good, but for the 'GetKey' it's not good with your current code.

You are setting the vertical and horizontal to zero at the beginning of each update, so it will be unreliable to read in FixedUpdate. You can safely read 'GetKey' inside fixed update (just not KeyDown/Up, or any other '1 frame' event).
