Question by IanMancuso · Jul 04, 2017 at 02:54 PM · 2dscripting problemphysics2d-physicsmotor

Cannot set motor speed in script

I cannot seem to set the motor speed of a motor with this script. I can set it manually from within unity, but it does not work from the script. Here is my code:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class Paddle : MonoBehaviour {
     private Rigidbody2D rb2d;
     private JointMotor2D motor;
     public float speed = 100;
     // Use this for initialization
     void Start () {
         rb2d = GetComponent<Rigidbody2D> ();
         motor = GetComponent<JointMotor2D> ();
     }
     
     // Update is called once per frame
     void Update () {
         if (Input.GetKeyDown ("left"))
             motor.motorSpeed = speed;
     }
 
     void FixedUpdate ()
     {
         
         
     }
 }

In this line :

 public float speed = 100;

change it to :

public float speed = 100f;

forget this.

the problem is: there is no key called "left" try this :

   using System.Collections;
   using System.Collections.Generic;
   using UnityEngine;
   
   public class Paddle : MonoBehaviour {
       private Rigidbody2D rb2d;
       private JointMotor2D motor;
       public float speed = 100f;
       // Use this for initialization
       void Start () {
           rb2d = GetComponent<Rigidbody2D> ();
           motor = GetComponent<JointMotor2D> ();
       }
       
       // Update is called once per frame
       void Update () {
           if (Input.GetKeyDown (KeyCode.Space))
               motor.motorSpeed = speed;
       }
       }

That, unfortunately, did not change anything.

I think I got the problem . the problem is there is no key called "left" try this

  using System.Collections;
  using System.Collections.Generic;
  using UnityEngine;
  
  public class Paddle : $$anonymous$$onoBehaviour {
      private Rigidbody2D rb2d;
      private Joint$$anonymous$$otor2D motor;
      public float speed = 100f;
      // Use this for initialization
      void Start () {
          rb2d = GetComponent<Rigidbody2D> ();
          motor = GetComponent<Joint$$anonymous$$otor2D> ();
      }
      
      // Update is called once per frame
      void Update () {
          if (Input.Get$$anonymous$$eyDown ($$anonymous$$eyCode.Space))
              motor.motorSpeed = speed;
      }
      }
