My 2d objects won't collide with each other

Which objects are you talking about? What is happening? How did you want the objects to work? One screenshot is not enough to give any sort of advice.

 

um my columns and the round objects both have rigidbody2d,box collider and circle collider but they wont collide with each other they just pass through each other

 

what part of the program can i show you so you can help me

 

the ball and the colums wont collide

 

You still missed the main point, we would like to see the script where you handle the movement of the 2D objects.
My wild guess is that you are moving them with tranform.position, or tranform.translate and therefore you are placing them over eachother overriding physics.

 

public class CircleMovement : MonoBehaviour
{

Vector3 velocity = Vector3.zero;
float bouncespeed = 10f;
float forwardSpeed = 1f;

Animator animator;
public bool dead = false;
float deathCooldown;
public bool godMode = false;

bool didjump = false;







// Use this for initialization
void Start()
{

animator = transform.GetComponentInChildren<Animator>();

if (animator == null)
{
Debug.LogError("Didn't find animator!");
}
}

// Do Graphic & Input updates here
void Update() {


if (Input.GetKeyDown(KeyCode.Space) || Input.GetMouseButtonDown(0))
{
didjump = true;
}

}


void FixedUpdate()

{

if (dead)
return;


GetComponent<Rigidbody2D>().AddForce(Vector2.right * forwardSpeed);

if (didjump)
NewMethod();

if (GetComponent<Rigidbody2D>().velocity.y > 0)
{
transform.rotation = Quaternion.Euler(0, 0, 0);
}
else {
float angle = Mathf.Lerp(0, -90, (-GetComponent<Rigidbody2D>().velocity.y / 3f));
transform.rotation = Quaternion.Euler(0, 0, angle);
}
}

private void NewMethod()
{
GetComponent<Rigidbody2D>().AddForce(Vector2.right * forwardSpeed);
GetComponent<Rigidbody2D>().AddForce(Vector2.up * bouncespeed);
NewMethod1();

didjump = false;
}

private void NewMethod1()
{
animator.SetTrigger("dobounce");
}

OnCollisionEnter2D void (Collision2D collision)
{
if (godMode)
return;

animator.SetTrigger("Death");
dead = true;
deathCooldown = 0.5f;
}
}

 

public class Camerafollow : MonoBehaviour
{
Transform player;

float offsetX;

// Use this for initialization
void Start()
{
GameObject player_go = GameObject.FindGameObjectWithTag("Player");

if (player_go == null)
{
Debug.LogError("Couldn't find an object with tag 'Player'!");
return;

}

player = player_go.transform;

offsetX = transform.position.x - player.position.x;
}

// Update is called once per frame
void Update()
{
if (player != null)
{
Vector3 pos = transform.position;
pos.x = player.position.x + offsetX;
transform.position = pos;

}
}
}

 

public class column : MonoBehaviour {
public Vector2 obstacleVelocity = new Vector2 (-7,0);

// Use this for initialization
void Start () {
GetComponent<Rigidbody2D>().velocity = obstacleVelocity;
}

// Update is called once per frame
void Update () {

}
}

 

Well, you went from too little information to too much information lol. Thanks for posting more info, but try to be more concise. All we need to know is what you want to happen, what is currently happening, and how you're currently trying to do it. Next time please use Code Tags when posting snippets of code.

Do you fully understand what setting an object to Kinematic does?

https://docs.unity3d.com/ScriptReference/Rigidbody-isKinematic.html

"Forces, collisions or joints will not affect the rigidbody anymore."

I have a feeling that is your issue. Try making your character Non-Kinematic.

 

Thank you for the advice hahahaha im very new in coding i just started learning so HAHAHA im not good

 

the background is kinamatic if i un-kinematic it the background falls

 

Not a problem, you're in the right place. Please let me know if that fixes your issue, or if you're still having trouble with your collisions.

 

The background can be kinematic if it doesn't need to move using physics. The background likely doesn't need a rigidbody at all, just a collider. Only one of the objects colliding requires a Rigidbody component. In this case that would be your circle character.

Also, it falls because the rigidbody gravity is set to a value above 0.

 

even if i put the gravity to zero it still falls

 

OHHH THANKSS!

 

i changed the value to a negative value but it still becomes tilt

 

I think you can remove the rigidbody from your obstacles. They don't need to move with physics, right? They just need to stay still and block the character? If that sounds right, then all they need is a collider. Your circle guy needs a collider and a rigidbody to move using physics.

 

OK thanks i get my problem and i have a last question if i have a column i want to put upside down but it is not kinematic how can i do that?

 

how can i hang the column?

 

When you say "hang" do you mean simply be upside down and on the top of the screen? Or do you want it to use physics and move when the character hits it?

 

um i solved it already i have a new problem my object collides with the column but when it collides it should change scene this is my script for that
public Vector2 jumplength = new Vector2(0f, 300f);
// Use this for initialization
void Start()
{

}

// Update is called once per frame
void Update()
{

if (Input.GetKeyDown(KeyCode.Space) || Input.GetMouseButtonDown(0))
{
GetComponent<Rigidbody2D>().velocity = Vector2.zero;
GetComponent<Rigidbody2D>().AddForce(jumplength);
}

}
void Die()
{
SceneManager.LoadScene(2);
}

void OnCollisionEnter2D(Collider2D collision)
{
if (collision.gameObject.tag == "enemy")
{ Die(); }
}
}
but it won't change scene

 

Please use CODE TAGS: http://forum.unity3d.com/threads/using-code-tags-properly.143875/

First of all, you dont need to get the rigidbody2d component every frame, its enough to get it once

Code (CSharp):

1.  
2. public Vector2 jumplength = new Vector2(0f, 300f);
3. private Rigidbody2D theRigidbody;
4. // Use this for initialization
5. void Start()
6. {
7. theRigidbody =GetComponent<Rigidbody2D>(); //Get the Rigidbody2D component
8. }
9.  
10. // Update is called once per frame
11. void Update()
12. {
13.   if (Input.GetKeyDown(KeyCode.Space) || Input.GetMouseButtonDown(0))
14.   {
15.     theRigidbody.velocity = Vector2.zero; //Set the velocity of the rigibody2d to 0
16.      theRigidbody.AddForce(jumplength);//Add some force
17.   }
18. }
19. void Die(){
20.         SceneManager.LoadScene(2);
21. }
22.  
23. void OnCollisionEnter2D(Collider2D collision)
24. {
25.     if (collision.gameObject.tag == "enemy") {
26.           Die();
27.    }
28. }
29. }

Secondly, your mistake is that the columns do not have their tags set to enemy.
In order to do that you should:

Reference: https://docs.unity3d.com/Manual/Tags.html

 

i put the tag in enemy on the columns it still wont change scene

 

hey freinds how do i make the rigidbody dynamic and also the player doesn't fall

 

Only 4 years old thread...

And why not ask this in your own thread?

 

that's right
