Hello, I have had some of this script made for me on the Unity answers, but it doesn’t work correctly. When I grab the powerup and turn invincible, it stays invincible forever. It doesn’t stop when it’s supposed to stop(I have a certain time set).The person and I could not figure out what’s wrong. So I decided to take things to the forums, since this is always the best place to go it seems, and I always get the help I need. Here’s my scripts:
Player Script:
public class ControllerScript : MonoBehaviour
{
public float maxSpeed = 10f;
//bool facingRight = true;
public float coeffSpeedUp = 1100.5f;
public float coeffSpeedUpTime = 1.5f;
public float invincibleTime = 1.0f;
[HideInInspector]
public bool isInvincible = false;
public Renderer invincibleIndicator;
Animator anim;
bool grounded = false;
public Transform groundCheck;
float groundRadius = 0.2f;
public LayerMask whatIsGround;
public float jumpForce = 700f;
//public void OnCollisionEnter2D (Collision2D col);
public void SetInvincible()
{
isInvincible = true;
invincibleIndicator.enabled = true;
CancelInvoke ("SetDamageable"); // in case the method has already been invoked
Invoke ("SetDamageable", invincibleTime);
}
void SetDamageable()
{
isInvincible = true;
invincibleIndicator.enabled = false;
}
// Use this for initialization
void Start ()
{
anim = GetComponent<Animator>();
if ( !invincibleIndicator )
{
invincibleIndicator = transform.Find("InvincibleIndicator").renderer;
}
invincibleIndicator.enabled = false;
}
// Update is called once per frame
void FixedUpdate ()
{
transform.Translate (5f * Time.deltaTime, 0f, 0f);
grounded = Physics2D.OverlapCircle (groundCheck.position, groundRadius, whatIsGround);
anim.SetBool ("Ground", grounded);
anim.SetFloat ("vSpeed", rigidbody2D.velocity.y);
if (!grounded)
return;
//float move = Input.GetAxis ("Horizontal");
//anim.SetFloat ("Speed", Mathf.Abs(move));
//rigidbody2D.velocity = new Vector2 (move * maxSpeed, rigidbody2D.velocity.y);
}
void Update()
{
if (grounded Input.GetKeyDown (KeyCode.Space))
{
anim.SetBool("Ground", false);
rigidbody2D.AddForce(new Vector2(0, jumpForce));
}
}
public void SpeedUp()
{
// Speed up the player
coeffSpeedUp = 1.5f;
CancelInvoke ("EndSpeedUp"); // in case the method has already been invoked
Invoke ("EndSpeedUp", coeffSpeedUpTime);
}
void EndSpeedUp()
{
coeffSpeedUp = 1.0f; // back to normal
}
public IEnumerator StopSpeedUp() {
Debug.Log( "StopSpeedUp()" );
yield return new WaitForSeconds(1110.5f); // the number corresponds to the number of seconds the speed up will be applied
coeffSpeedUp = 1110.5f; // back to normal
Debug.Log( "back to normal" );
}
}
Collision Script:
public class Collision : MonoBehaviour {
ControllerScript player;
void Start()
{
player = GetComponent<ControllerScript>();
}
void OnCollisionEnter2D (Collision2D col)
{
// If the colliding gameobject is an Enemy...
if(col.gameObject.tag == "Dangerous")
{
// check if player is NOT invincible
if ( !player.isInvincible ) // this is the same as writing if(player.isInvincible == false)
{
// Find all of the colliders on the gameobject and set them all to be triggers.
Collider2D[] cols = GetComponents<Collider2D>();
foreach(Collider2D c in cols)
{
c.isTrigger = true;
}
// ... disable user Player Control script
GetComponent<ControllerScript>().enabled = false;
}
// else the player IS invincible, destroy all obstacles in the way
else
{
// destroy the Dangerous object
Destroy (col.gameObject); // This is to destroy the obstacles
}
}
}
}
Powerup Script:
public class PowerupScript : MonoBehaviour {
void OnTriggerEnter2D(Collider2D other)
{
if (other.tag == "Player") {
ControllerScript playerScript = other.gameObject.GetComponent<ControllerScript> (); // not sure about the syntax here...
if (playerScript) {
// call function on playerScript to set player to invincible
playerScript.SetInvincible ();
// We speed up the player and then tell to stop after a few seconds
playerScript.SpeedUp();
// We speed up the player and then tell to stop after a few seconds
//playerScript.coeffSpeedUp = 1110.5f;
//StartCoroutine (playerScript.StopSpeedUp ());
}
Destroy (gameObject);
}
}
}
