hello, I started recently in the world of unity and they gave me this script, I’ve been 2 months trying to make the character jump more when I keep pressing the jump button, unfortunately I haven’t got any result, here is the code if someone can help me :C
using UnityEngine;
using System.Collections;
public class Controller : MonoBehaviour
{
public class GroundState
{
private GameObject player;
private float width;
private float height;
private float length;
//GroundState constructor. Sets offsets for raycasting.
public GroundState(GameObject playerRef)
{
player = playerRef;
width = player.GetComponent<Collider2D>().bounds.extents.x + 0.1f;
height = player.GetComponent<Collider2D>().bounds.extents.y + 0.2f;
length = 0.05f;
}
//Returns whether or not player is touching wall.
public bool isWall()
{
bool left = Physics2D.Raycast(new Vector2(player.transform.position.x - width, player.transform.position.y), -Vector2.right, length);
bool right = Physics2D.Raycast(new Vector2(player.transform.position.x + width, player.transform.position.y), Vector2.right, length);
if (left || right)
return true;
else
return false;
}
//Returns whether or not player is touching ground.
public bool isGround()
{
bool bottom1 = Physics2D.Raycast(new Vector2(player.transform.position.x, player.transform.position.y - height), -Vector2.up, length);
bool bottom2 = Physics2D.Raycast(new Vector2(player.transform.position.x + (width - 0.2f), player.transform.position.y - height), -Vector2.up, length);
bool bottom3 = Physics2D.Raycast(new Vector2(player.transform.position.x - (width - 0.2f), player.transform.position.y - height), -Vector2.up, length);
if (bottom1 || bottom2 || bottom3)
return true;
else
return false;
}
//Returns whether or not player is touching wall or ground.
public bool isTouching()
{
if (isGround() || isWall())
return true;
else
return false;
}
//Returns direction of wall.
public int wallDirection()
{
bool left = Physics2D.Raycast(new Vector2(player.transform.position.x - width, player.transform.position.y), -Vector2.right, length);
bool right = Physics2D.Raycast(new Vector2(player.transform.position.x + width, player.transform.position.y), Vector2.right, length);
if (left)
return -1;
else if (right)
return 1;
else
return 0;
}
}
//Feel free to tweak these values in the inspector to perfection. I prefer them private.
public float speed = 14f;
public float accel = 6f;
public float airAccel = 3f;
public float jump = 14f; //I could use the "speed" variable, but this is only coincidental in my case. Replace line 89 if you think otherwise.
private GroundState groundState;
void Start()
{
//Create an object to check if player is grounded or touching wall
groundState = new GroundState(transform.gameObject);
}
private Vector2 input;
void Update()
{
//Handle input
if (Input.GetKey(KeyCode.LeftArrow))
input.x = -1;
else if (Input.GetKey(KeyCode.RightArrow))
input.x = 1;
else
input.x = 0;
if (Input.GetKeyDown(KeyCode.UpArrow))
input.y = 1;
//Reverse player if going different direction
transform.localEulerAngles = new Vector3(transform.localEulerAngles.x, (input.x == 0) ? transform.localEulerAngles.y : (input.x + 1) * 90, transform.localEulerAngles.z);
}
void FixedUpdate()
{
GetComponent<Rigidbody2D>().AddForce(new Vector2(((input.x * speed) - GetComponent<Rigidbody2D>().velocity.x) * (groundState.isGround() ? accel : airAccel), 0)); //Move player.
GetComponent<Rigidbody2D>().velocity = new Vector2((input.x == 0 && groundState.isGround()) ? 0 : GetComponent<Rigidbody2D>().velocity.x, (input.y == 1 && groundState.isTouching()) ? jump : GetComponent<Rigidbody2D>().velocity.y); //Stop player if input.x is 0 (and grounded) and jump if input.y is 1
if (groundState.isWall() && !groundState.isGround() && input.y == 1)
GetComponent<Rigidbody2D>().velocity = new Vector2(-groundState.wallDirection() * speed * 0.75f, GetComponent<Rigidbody2D>().velocity.y); //Add force negative to wall direction (with speed reduction)
input.y = 0;
}
}
