Obstacles won't destroy on collision?

Questions & Answers

Hello again for the 100th time, I am trying to have my player be able to destroy/pass through obstacles in the game when he grabs a certain powerup. I have already made a script for it but it’s not working so something is wrong here. Been trying to figure out the problem all day. Can anyone please help me see what I’m missing in my script? Here’s my 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.coeffSpeedUp = 10.5f;
								StartCoroutine (playerScript.StopSpeedUp ());


						}
						Destroy (gameObject); //This is to destroy the powerup
				}
		}

			void OnCollisionEnter2D(Collision2D col)
			{
				if (col.gameObject.tag == "Dangerous") {
						Destroy (col.gameObject); // This is to destroy the obstacles
				}
		    }


		}

And my Collision script that’s attached to the player if you need it:

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;
			}
		}
	}
}

First, remove the OnCollisionEnter2D method from your PowerUp script. This has nothing to do with the player touching the Dangerous object, all it does is set the player to invincible. The power up doesn’t collide with the Dangerous object, the player collides with the Dangerous object.

Second, look at the OnCollisionEnter2D on the player. It checks if the player is NOT invincible, then disables the controller and turns the player collider to triggers (making the player fall to the death zone below).

So you already have a collision function that detects the Dangerous object on the player. Now it is just a continuation from where it checks if the player is invincible.

// check if player is NOT invincible
if ( !player.isInvincible ) 
{
	// death type stuff
}
// else the player IS invincible, destroy all obstacles in the way
else
{
	// invincible type stuff
}

So how does this look in your player collision script?

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
		}
	}
}
