The character can hang on flat walls (it should not)

We have a problem : when the character in running in front of a wall, it is as if there is no gravity. In addition, the character is a cube with legs, so he can hang on with his chin. I desesparetly search a way to solve both these problems. I tried to make a weird collider to avoid these errors, but it didn't wokt out.

I am asking for your help. Thanks in advance.






(second pic) : it should fall, but when running, the force counter the gravity.

 

I affirm I don't want the character to hang on walls like that, it should fall. Here is the method for the movements (it is a bit messy, I came up with it myself so it is probably the source of the problem)

Code (CSharp):

1.     void Update () {
2.         if(Input.GetKeyDown("space") && isGrounded == true && isAllowedToMove ==true){
3.             Jump();
4.         }
5. // right Movement
6.     if(Input.GetKey("right") && isAlive == true && isAllowedToMove ==true){
7.             vitesse = 7;      
8.             SetVelocity(vitesse, 0);
9.             animator.SetBool("isMoving", true);
10.             animator.SetBool("isMovingBack", false);
11.     }
12.     if(Input.GetKeyUp("right")  && isAlive == true && isAllowedToMove ==true && isGrounded==true){
13.             vitesse = 0;      
14.             SetVelocity(vitesse, 0);
15.             animator.SetBool("isMoving", false);
16.             animator.SetBool("isMovingBack", false);
17.     }
18. //Sert à arrêter l'animation de course en vol
19.     if(Input.GetKeyUp("right")  && isAlive == true && isAllowedToMove ==true && isGrounded==false){
20.             animator.SetBool("isMoving", false);
21.             animator.SetBool("isMovingBack", false);
22.     }
23.  
24. // left Movement
25.     if(Input.GetKey("left")  && isAlive == true && isAllowedToMove ==true){
26.             vitesse = -7;      
27.             SetVelocity(vitesse, 0);
28.             animator.SetBool("isMovingBack", true);
29.             animator.SetBool("isMoving", false);
30.     }
31.     if(Input.GetKeyUp("left")  && isAlive == true && isAllowedToMove ==true && isGrounded==true){
32.             vitesse = 0;      
33.             SetVelocity(vitesse, 0);
34.             animator.SetBool("isMovingBack", false);
35.             animator.SetBool("isMoving", false);
36.         }
37. //Sert à arrêter l'animation de course en vol
38.     if(Input.GetKeyUp("left")  && isAlive == true && isAllowedToMove ==true && isGrounded==false){
39.         animator.SetBool("isMovingBack", false);
40.         animator.SetBool("isMoving", false);
41.         }
42.  
43. }
44.  
45. //jump Movement
46. void Jump(){
47.         rb.velocity += new Vector2(0, maxJump);
48.     }
49.  
50. void SetVelocity(float xVelocity, float yVelocity){
51.     rb.velocity = new Vector2(0, rb.velocity.y);
52.     rb.velocity += new Vector2(xVelocity, yVelocity);
53. }

 

Thank you very much for the example, but do you think the IsGrounded method is the only problem or should I change the whole movement method ?

I also forgot to show the way I changed the IsGrounded state :

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5.  
6. public class FeetDetector : MonoBehaviour
7. {
8.     private CharacBehavior cB;
9.     // Start is called before the first frame update
10.     void Start()
11.     {
12.           cB = GameObject.Find("Personnage").GetComponent<CharacBehavior>();
13.     }
14.  
15.     // Update is called once per frame
16.     void Update()
17.     {
18.         Debug.DrawRay(gameObject.transform.position, transform.TransformDirection(Vector3.down) *0.2f, Color.red);
19.         RaycastHit2D hit = Physics2D.Raycast(gameObject.transform.position, transform.TransformDirection(Vector3.down), 0.2f);
20.         if(hit.collider !=null && hit.collider.gameObject.CompareTag("Ground")){
21.             cB.isGrounded = true;
22.         }
23.         else{
24.             cB.isGrounded = false;
25.         }
26.     }
27. }
28.  

 

Thanks a lot I will try all of this. You are awesome.

 

There is still an isue, the character should be able to change direction, even if he is not grounded (like adjusting position while in air ). So desactivate the velocity or equivalent is not possible...
Maybe have I misunderstood your proposition ?

 

I also figured out that the fiction of the material is one of the causes, but I can't delete it, otherwise my character is going to slide around.

 

After a few tests with your script Ii can confirm that the issue is the friction of the floor. I used it to stop my character right after a jump (beacause he kept the x velocity to jump). Unfortunately I still need the friction to stop the infinite slide my character is doing after a jump. I can't figure out a way to do that without the friction (this is my firts game so I lack of ways to fig bugs hahaha).

 

Maybe I did it wrong, but even with your scene I get the same issue... The character still can't fall while running in walls...

 

Okay my bad I dit it wrong hahaha. It work in your scene, but (sorry I am new) I don't really understand what makes the character not pushing ( I mean what line of the code, so I can try to reproduce it).

 

I tried to remove all the stuff from a clone of my game, leaving only the character movements. It would be amazing if you could take a look.

No, unfortunately all I tried to change failed. Do you think I need to change it fundamentally ?

 

I gave you the access. Thank you so much for your help, we need more people like you hahaha.

 

Sorry to bother you again, but I find strange the use of the contact filter. This method gives some errors. The strangest thing is if I try to debug log the state of the IsGroundedBelow, it switches every frame from true to false (even if I just don't moove). I now have problems with some moving platforms, because the state IsGroundedBelow seems not ot work perfectly. Do you have any idea about what is going on ?
