Hello all,
New to C# here, any programming language on that note. I am teaching myself C# by making a little game and found myself running into an issue. I have created an array of enemies at the beginning of my code, when a play collides with an enemy, the play is knocked back a short distance (Currently using around 8 force). This is working great when there is only a single enemy, however if add more the one enemy, it will base the collision script on what ever the highest enemy is within the array.
I am using loop that will looking for enemies in the array but can’t seem to get this fixed. Any help would be most appreciated. Here is my script below;
using UnityEngine;
using System.Collections;
public class Movement : MonoBehaviour
{
public float maxSpeed = 10f; // Character movement speed.
public bool grounded = false; //is the Character grounded?
public Transform groundCheck; // Used for creating grounded
float groundRadius = 0.2f; //
public LayerMask whatIsGround; // Marker to show where the ground is
float jumpForce = 15f; // Force for vertical velocity (jumping)
float knockForce = 8f; // Force which the character will be knocked on both axis
float travelTime = 0.1f; // Timer to set how often the timer will check for grounded to reset velocity
public float doubleJump = 1; // Double jump limit
bool movement = true; // Disables movement during knockbacks
public int enemyIndex = 0; // Used to check array each from in a enemyIndex++
Vector3 enemy_pos;
private GameObject[] Enemy;
void Start(){
Enemy = GameObject.FindGameObjectsWithTag ("Enemy"); // Define what is Enemy using tag Enemy
enemy_pos = Enemy[enemyIndex].transform.position; // Define the position of the Enemy array
}
void Update(){
enemyPosition ();
grounded = Physics2D.OverlapCircle (groundCheck.position, groundRadius, whatIsGround); // Checks for grounded
if (movement) {
// Character Movement
if (Input.GetKey (KeyCode.A)) {
transform.position += Vector3.left * maxSpeed * Time.deltaTime;
}
if (Input.GetKey (KeyCode.D)) {
transform.position += Vector3.right * maxSpeed * Time.deltaTime;
}
if (Input.GetKey (KeyCode.W)) {
transform.position += Vector3.up * maxSpeed * Time.deltaTime;
}
if (Input.GetKey (KeyCode.S)) {
transform.position += Vector3.down * maxSpeed * Time.deltaTime;
}
}
// Jumping
if (grounded && Input.GetButtonDown ("Jump")) {
rigidbody2D.velocity = new Vector2 (0, jumpForce);
}
// Double jump
if (!grounded && Input.GetButtonDown ("Jump") && doubleJump > 0) {
rigidbody2D.velocity = Vector2.zero;
rigidbody2D.velocity = new Vector2 (0, jumpForce);
doubleJump = 0;
} else if (grounded == true) {
doubleJump = 1;
}
}
void OnCollisionStay2D(Collision2D coll) {
if (coll.gameObject.tag == "Enemy") {
// rigidbody2D.velocity = new Vector2 (-8, 8); -- Old Code
rigidbody2D.velocity = (knockForce * (transform.position - enemy_pos));
Debug.Log (knockForce * (transform.position - enemy_pos));
StartCoroutine (knockBack (travelTime));
movement = false;
}
}
IEnumerator knockBack(float travelTime) {
yield return new WaitForSeconds (travelTime);
movement = true;
if (!grounded) {
StartCoroutine (knockBack (travelTime));
movement = false;
}
if (grounded){
rigidbody2D.velocity = Vector3.zero;
}
}
void enemyPosition(){
enemyIndex++;
if (enemyIndex >= Enemy.Length);
Debug.Log (Enemy.Length);
enemyIndex = 0;
}
}
Please don’t mind the pretty messy code. Will clean that up as I near the end of this particular script!
