There is a dynamic Rigidbody that can be launched with the mouse. But at some point, Rigidbody stops reacting to the mouse for some reason. Rigidbody's speed is 0.
To a rigidbody attached two Spring joints.
The only way to awaken the body is to disable and re-enable Spring Joints when debugging.

}
private bool clickedOn = false;

mouseWorldPoint.z = 0f;
if (Boundary.ballInBoundary)
{

float diffX = mouseWorldPoint.x - mouseWorldPointStart.x;
//TODO
for (int i = 0; i < springJoints.Length; i++)
{
springJoints[i].connectedAnchor = new Vector2(springJoints[i].connectedAnchor.x + diffX, springJoints[i].connectedAnchor.y);
}

What is the reason for this? How can this be corrected?
Replaced OnMouseDown() with Input.GetMouseButtonDown(0) and everything worked out.
void Update()
{
if (Input.GetMouseButtonDown(0))
{
SpringJointDeactivate();
clickedOn = true;
}
if (Input.GetMouseButtonUp(0))
{
SpringJointActivate();
clickedOn = false;
SetKinematicState(false);
Invoke("SpringJointDeactivate", 0.1f);

Here's my code for player movement. I have set up walking around and I am now Trying to change the sprite animation when walking in different directions. Everything was working fine but when I tried to change the sprite for walking up the sprite gets stuck in a loop and doesn't idle.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class PlayerMovement : MonoBehaviour
{
public Animator Animator;
[SerializeField] private float speed = 1f;
private Rigidbody2D body;
private Vector2 axisMovement;
// Start is called before the first frame update
void Start()
{
body = GetComponent<Rigidbody2D>();
}
// Update is called once per frame
void Update()
{
axisMovement.x = Input.GetAxisRaw("Horizontal");
axisMovement.y = Input.GetAxisRaw("Vertical");
Animator.SetFloat("Speed", Mathf.Abs(axisMovement.x));
if (Input.GetKey(KeyCode.W))
{
Animator.SetBool("isforward", true);
}
if (Input.GetKey(KeyCode.A))
{
Animator.SetBool("isforward", false);
}
if (Input.GetKey(KeyCode.S))
{
Animator.SetBool("isforward", false);
}
if (Input.GetKey(KeyCode.D))
{
Animator.SetBool("isforward", false);
}
}
private void FixedUpdate()
{
Move();
}
private void Move()
{
body.velocity = axisMovement.normalized * speed;
CheckForFlipping();
}
private void CheckForFlipping()
{
bool movingLeft = axisMovement.x < 0;
bool movingRight = axisMovement.x > 0;
if (movingLeft)
{
transform.localScale = new Vector3(-1f, transform.localScale.y);
}
if (movingRight)
{
transform.localScale = new Vector3(1f, transform.localScale.y);
}
}
}
I also tried doing Animator.SetFloat("Speed", Mathf.Abs(axisMovement.x)); but switch it with axisMovement.y but that stops all the animations moving left and right stop working. 😢
I've figured it out. here's the updated code
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class PlayerMovement : MonoBehaviour
{
public Animator Animator;
[SerializeField] private float speed = 1f;
private Rigidbody2D body;
private Vector2 axisMovement;
// Start is called before the first frame update
void Start()
{
body = GetComponent<Rigidbody2D>();
}
// Update is called once per frame
void Update()
{
axisMovement.x = Input.GetAxisRaw("Horizontal");
axisMovement.y = Input.GetAxisRaw("Vertical");
Animator.SetFloat("Speed", Mathf.Abs(axisMovement.x + axisMovement.y));
if (Input.GetKey(KeyCode.W))
{
Animator.SetBool("isforward", true);
} else {
Animator.SetBool("isforward", false);
}
// if (Input.GetKey(KeyCode.A))
// {
// Animator.SetBool("isforward", false);
// }
// if (Input.GetKey(KeyCode.S))
// {
// Animator.SetBool("isforward", false);
// }
// if (Input.GetKey(KeyCode.D))
// {
// Animator.SetBool("isforward", false);
// }
}
private void FixedUpdate()
{
Move();
}
private void Move()
{
body.velocity = axisMovement.normalized * speed;
CheckForFlipping();
}
private void CheckForFlipping()
{
bool movingLeft = axisMovement.x < 0;
bool movingRight = axisMovement.x > 0;
if (movingLeft)
{
transform.localScale = new Vector3(-1f, transform.localScale.y);
}
if (movingRight)
{
transform.localScale = new Vector3(1f, transform.localScale.y);
}
}
}
When creating the game, I came across the problem that after adding animation to the player's code in the play mode, he stopped moving.
I did everything as usual, went into the animator, made an animation, and then set up and added everything necessary to the code in the animator, but after that the player stopped moving although before that everything was fine.
Help me, I hope it's not difficult.
Here is the code
using System.Collections;

I don't understand why this is happening
I want to play a video in WebGL but it keeps blocking my video due to one line of code and I don't know why or how to "repair" it. When clicking on play, only one frame is shown and then it stops. (Entire code below).
The issue is this particular line in my Update function:
if (video.isPlaying)
{
if (!video.isPrepared) return;
videoSlider.value = (float)NTime; //This line here!!!
}
If not commented out, the video wont play, for whatever reason.
NTime, which seems to cause the issue, is:
video.time/ ((ulong)(video.frameCount / video.frameRate)) //video is videoPlayer

i made 2d character and 3 ui buttons and they worked well
but the problem is when moving to the right or left by the ui buttons i can't jump however when jump from the ui button i can move to right and left
this is the script
public class PlayerWalk : MonoBehaviour {
private PlayerAnimation playerAnim;
private Rigidbody2D myBody;
private SpriteRenderer spriteRenderer;
public float speed = 7f;
public float jumpForce = 7f;
private bool moveLeft; // determine if we move left or right

}
} // class
the 2d character moves well and there is no bugs or problems with scripts
Any help??
I don't know where is the problem??
**Note ** i used unity5.6
I would say onTriggerEnter2D instead of using onCollisionEnter2D would be a better option in this scenario. You can read more about that here.
https://answers.unity.com/questions/875770/ontriggerenter-or-oncollisionenter-1.html#:~:text=OnCollisionEnter%20is%20called%20when%20two,with%20%22IsTrigger%22%20set).
Did you try to debug the value of canJump while you are trying to move left or right?
I am creating a top down zombie shooter and I have made the zombie do damage to the player when it is touching the player. However when the player backs away from the zombie after taking damage, the players health will continue to drop. Any ideas on how to fix this would be appreciated.
public float moveSpeed= 5f;
public Rigidbody2D rb;
public Camera cam;
public float playerHealth = 100;
public float enemyDamage = 25;
public GameObject gameOverScreen;
Vector2 movement;
Vector2 mousePos;
// Update is called once per frame
void Update()
{
movement.x = Input.GetAxisRaw("Horizontal");
movement.y = Input.GetAxisRaw("Vertical");
mousePos = cam.ScreenToWorldPoint(Input.mousePosition);
if(playerHealth == 0)
{
gameOverScreen.SetActive(true);
}
}
void FixedUpdate()
{
rb.MovePosition(rb.position + movement * moveSpeed * Time.fixedDeltaTime);
Vector2 lookDir = mousePos - rb.position;
float angle = Mathf.Atan2(lookDir.y, lookDir.x) * Mathf.Rad2Deg - 90f;
rb.rotation = angle;
}
void OnCollisionEnter2D(Collision2D collision)
{
if (collision.gameObject.CompareTag("Enemy"))
{
StartCoroutine(DamagePlayer());
}
else
{
StopCoroutine(DamagePlayer());
}
}
IEnumerator DamagePlayer()
{
while(true)
{
yield return new WaitForSeconds(1);
playerHealth -= enemyDamage;
}
}
First of all for doing something if it is not colliding anymore you should use OnCollisionExit2D
Then you can either use it the way you did using
StopCoroutine(DamagePlayer());
Or if want to be sure you could either store a reference to your routine
private Coroutine routine;
void OnCollisionEnter2D(Collision2D collision)
{
if (collision.gameObject.CompareTag("Enemy"))
{
if(routine == null)
{
routine = StartCoroutine(DamagePlayer());
}
}
else
{
if(routine != null) StopCoroutine(routine);
}
}
private void OnCollisionEnter2D(Collision2D collision)
{
if(routine != null) StopCoroutine (routine);
}
or use a bool flag in order to terminate it
private bool cancelRoutine = true;
void OnCollisionEnter2D(Collision2D collision)
{
if (collision.gameObject.CompareTag("Enemy"))
{
if(cancelRoutine) routine = StartCoroutine(DamagePlayer());
}
else
{
cancelRoutine = true;
}
}
private void OnCollisionEnter2D(Collision2D collision)
{
cancelRoutine = true;
}
IEnumerator DamagePlayer()
{
cancelRoutine = false;
while(! cancelRoutine)
{
yield return new WaitForSeconds(1);
playerHealth -= enemyDamage;
}
}
In general you could solve this without a routine by directly using OnCollisionStay2D like e.g.
void OnCollisionEnter2D(Collision2D collision)
{
if (collision.gameObject.CompareTag("Enemy"))
{
timer = 1;
}
}
void OnCollisionStay2D(Collision2D collision)
{
if (collision.gameObject.CompareTag("Enemy"))
{
timer -= Time.deltaTime;
if(timer <= 0)
{
timer = 1;
playerHealth -= enemyDamage;
}
}
}
