Question Linear Drag

Hi all,
I am making the player to slow down the fall while in air if a button is pressed. My believe was that this is done by modifying the linear drag. I was able to write the code that every time the button is pressed while the player is in air the linear drag goes from 0 to a higher number, lets say 10, but the player still falls with the same speed. Any idea if there is a setting in the rigidbody2d that i need to set for the fall to be affected by the linear drag value? Thank you.

 

Unless you're applying gravity for each object manually, no. You're going to have to apply a constant force to your object upwards.

 

I think you have a bug. The above works just fine.

Code (csharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. // @kurtdekker - drop this on an empty GameObject, press PLAY, observe.
6.  
7. public class FallDrag : MonoBehaviour
8. {
9.     IEnumerator Start ()
10.     {
11.         while( true)
12.         {
13.             var position = new Vector2( Random.Range( -6.0f, 6.0f), 5.0f);
14.  
15.             var cube = GameObject.CreatePrimitive(PrimitiveType.Cube);
16.             cube.transform.position = position;
17.             DestroyImmediate( cube.GetComponent<Collider>());
18.  
19.             cube.AddComponent<BoxCollider2D>();
20.  
21.             var rb2d = cube.AddComponent<Rigidbody2D>();
22.  
23.             // get CallAfterDelay class from:
24.             // https://gist.github.com/kurtdekker/0da9a9721c15bd3af1d2ced0a367e24e
25.             CallAfterDelay.Create(
26.                 Random.Range( 0.5f, 1.0f),
27.                 () => {
28.                     rb2d.drag = 10;
29.                 }
30.             ).transform.SetParent( cube.transform);
31.  
32.             CallAfterDelay.Create(
33.                 10.0f,
34.                 () => {
35.                     Destroy( cube);
36.                 }
37.             ).transform.SetParent( cube.transform);
38.  
39.             yield return new WaitForSeconds( Random.Range( 0.5f, 1.0f));
40.         }
41.     }
42. }

 

I thought so. I can see the linear drag value increase when i push the button, but the fall is not affected at all. So weird.
