Hello anons,
Over the last 2 days i tried to program my first Unity Game in C#.
I got one major problem.
If I jump on enemies it happens that either

• only I die.
  
• me and the enemy dies.
  

Also the "You Won!"-Canvas i created doesnt appear if I hit the Exit.

Besides that i want to create a GUI and Multiplayer for the game so i can play with friends. If someone has a little knowledge of Unity and c# please leave a comment.  🙂
The Files can be found at: google.com/open?id=1bOR4Q63zP6NMgy6LNx4qm6z1S8VPVqrY]https://drive[WARNING POSSIBLY INFECTED]google.com/open?id=1bOR4Q63zP6NMgy6LNx4qm6z1S8VPVqrY

Thank you in advance!

I suppose on the OnTouch event or whatever it is, you could have some code like (pseudocode)

if (player.Y =< monster.Height * 0.9) { // if players vertical position is higher than 0.9 of the monsters height, you've successfully killed it
monster.Die();
} else {
player.Die();
}

Thank you for your answer i'll try to fix it.
But maybe you could look at the Source Code so you can see how i did it

Here are the two scripts in the game (c#):

PlayerController.cs

Code

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;


public class PlayerController : MonoBehaviour {

  public SpriteRenderer sprite;
  public LayerMask groundLayer;
  public Transform groundCheck;
  public float groundCheckRadius;
  private bool groundCollision;
  private bool doubleJumped;
  public CanvasGroup canvasYouWin;
  private int lives = 3;


  void Start () {

  }

  void FixedUpdate () {
    groundCollision = Physics2D.OverlapCircle (groundCheck.position, groundCheckRadius, groundLayer);
  }

  void Update ()
  {
    var rigidBody = GetComponent<Rigidbody2D> ();
    var transform = GetComponent<Transform> ();
    if (Input.GetKey ("right")) {
      sprite.flipX = false;
      if (Input.GetKey ("left shift"))
        rigidBody.velocity = new Vector2 (10, rigidBody.velocity.y);
      else
        rigidBody.velocity = new Vector2 (5, rigidBody.velocity.y);
    }

    if (Input.GetKey ("left")) {
      sprite.flipX = true;
      if (Input.GetKey ("left shift"))
        rigidBody.velocity = new Vector2 (-10, rigidBody.velocity.y);
      else
        rigidBody.velocity = new Vector2 (-5, rigidBody.velocity.y);
    }

    if (groundCollision)
      doubleJumped = false;
    if (Input.GetKeyDown ("space") && groundCollision)
      rigidBody.velocity = new Vector2 (rigidBody.velocity.x, 10);
    if (Input.GetKeyDown ("space") && !groundCollision && !doubleJumped) {
      rigidBody.velocity = new Vector2 (rigidBody.velocity.x, 10);
      doubleJumped = true;
    }
    if (transform.position.y < -6) {
      lives -= 1;
      if (transform.position.x < 2)
        transform.position = new Vector2 (-5, 2);
      else
        transform.position = new Vector2 (2, 2);
    }
  
    if (lives == 0)
      SceneManager.LoadScene(SceneManager.GetActiveScene().name);
  }

  public void OnTriggerEnter2D (Collider2D other) {
    if (other.name == "EnemyDamage") {
      lives -= 1;
      transform.position = new Vector2 (2, 1);
    } else if (other.name == "exit") {
      canvasYouWin.alpha = 1;
    }
  }
}

EnemyController.cs

Code

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class EnemyController : MonoBehaviour {

  public bool moveLeft;
  public LayerMask groundLayer;
  public Transform wallCheck;
  public float wallCheckRadius;
  private bool wallCollision;
  private bool notAtEdge;
  public Transform edgeCheck;
  
  void Start () {
    moveLeft = true;
  }

  void FixedUpdate () {
    wallCollision = Physics2D.OverlapCircle (wallCheck.position, wallCheckRadius, groundLayer);
    notAtEdge = Physics2D.OverlapCircle (edgeCheck.position, wallCheckRadius, groundLayer);
  }
  
  void Update ()
  {
    var rigidBody = GetComponent<Rigidbody2D> ();

    if (wallCollision || !notAtEdge) {
      moveLeft = !moveLeft;
    }

    if (moveLeft) {
      transform.localScale = new Vector2 (1, 1);
      rigidBody.velocity = new Vector2 (-5, rigidBody.velocity.y);
    } else {
      transform.localScale = new Vector2 (-1, 1);
      rigidBody.velocity = new Vector2 (5, rigidBody.velocity.y);
    }
  }

  void OnTriggerEnter2D (Collider2D other) {
    if (other.name == "HeadStomper") {
      Destroy (gameObject);
    }
  }
}

I suppose on the OnTouch event or whatever it is, you could have some code like (pseudocode)

}

That is very bad .. @op look up raycast in unity to detect where the objects intersect and apply your logic here.
