Hey!
If any of you guys have a problem with this lesson here is the code that worked for me.
I tried pasting the code in the git commit but it didn’t work.
In the video, we are asked to Get the SpringJoint component of the ball but there isn’t one. So I made a Serialized field where i put the Spring Joint. I tried a lot of solutions and checked again and again if the code of the course worked but it didn’t. Anyway here is my code.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.InputSystem;
public class BallHandler : MonoBehaviour
{
[SerializeField] private GameObject ballPrefab;
[SerializeField] private Rigidbody2D pivot;
[SerializeField] private SpringJoint2D spring_joint; //ADDED
[SerializeField] private float detachDelay;
[SerializeField] private float respawnDelay;
private Rigidbody2D currentBallRigidbody;
private SpringJoint2D currentBallSprintJoint;
private Camera mainCamera;
private bool isDragging;
// Start is called before the first frame update
void Start()
{
mainCamera = Camera.main;
SpawnNewBall();
}
// Update is called once per frame
void Update()
{
if (currentBallRigidbody == null) { return; }
if (!Touchscreen.current.primaryTouch.press.isPressed)
{
if (isDragging)
{
LaunchBall();
}
isDragging = false;
return;
}
isDragging = true;
currentBallRigidbody.isKinematic = true;
Vector2 touchPosition = Touchscreen.current.primaryTouch.position.ReadValue();
Vector3 worldPosition = mainCamera.ScreenToWorldPoint(touchPosition);
currentBallRigidbody.position = worldPosition;
}
private void SpawnNewBall()
{
GameObject ballInstance = Instantiate(ballPrefab, pivot.position, Quaternion.identity);
currentBallRigidbody = ballInstance.GetComponent<Rigidbody2D>();
currentBallSprintJoint = spring_joint; //CHANGED
currentBallSprintJoint.enabled = true; //ADDED
currentBallSprintJoint.connectedBody = currentBallRigidbody;
}
private void LaunchBall()
{
currentBallRigidbody.isKinematic = false;
currentBallRigidbody = null;
Invoke(nameof(DetachBall), detachDelay);
}
private void DetachBall()
{
currentBallSprintJoint.enabled = false;
currentBallSprintJoint = null;
Invoke(nameof(SpawnNewBall), respawnDelay);
}
}
