Stop my character from walking through walls. I know whats wrong but i cant figure out how to fix it.
Hey unity community!
Im making a 2D platformer ( I know, very original) and my character moves and jumps around perfectly. My problem is that it keeps moving through walls.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Playermove : MonoBehaviour
{
Animator playeranimator;
Rigidbody2D playerRb;
public float speed = 4f;
bool facingRight;
private bool isGrounded;
public Transform feetpos;
public float checkradius;
public LayerMask whatisground;
public float jumpforce;
private float jumptimecounter;
public float jumptime;
private bool isJumping;
// Start is called before the first frame update
void Start()
{
playeranimator = GetComponent<Animator>();
playerRb = GetComponent<Rigidbody2D>();
}
// Update is called once per frame
void Update()
{
//get ground
isGrounded = Physics2D.OverlapCircle(feetpos.position, checkradius, whatisground);
//Get input
float movement = Input.GetAxis("Horizontal");
//Move along the x axis
Vector3 playerPosition = transform.position;
playerPosition.x = playerPosition.x + movement*speed *Time.deltaTime;
transform.position = playerPosition;
//Jump
if(isGrounded == true && Input.GetKeyDown(KeyCode.Space)){
isJumping = true;
jumptimecounter = jumptime;
playerRb.velocity = Vector2.up * jumpforce;
}
if(Input.GetKey(KeyCode.Space) && isJumping){
if(jumptimecounter > 0){
playerRb.velocity = Vector2.up * jumpforce;
jumptimecounter -= Time.deltaTime;
}
else{
isJumping = false;
}
}
if(Input.GetKeyUp(KeyCode.Space)){
isJumping = false;
}
/*
if(Input.GetKey(KeyCode.Space) )
{
playerRb.AddForce(Vector2.up*1f, ForceMode2D.Impulse);
}
*/
//prevent sliding down slopes
if(Input.GetKey(KeyCode.Space) == false || Input.GetAxis("Horizontal") == 0){
playerRb.constraints = RigidbodyConstraints2D.FreezePositionX | RigidbodyConstraints2D.FreezeRotation;
}
else{
playerRb.constraints = RigidbodyConstraints2D.FreezeRotation;
}
Flip(movement);
//Change Animation
playeranimator.SetFloat("Speed", speed*0.75f);
playeranimator.SetFloat("Move", Mathf.Abs(movement));
playeranimator.SetBool("Jump", isJumping);
}
void Flip(float m)
{
//Get current direction and compare it to movement direction
if(facingRight && m < 0 || !facingRight && m > 0)
{
//if they are not the same, then flip and change facingdirection
transform.Rotate(new Vector3(0,180,0));
facingRight = !facingRight;
}
}
}
Thats my movement script in its entirety. I wasnt sure how much of it was needed.
I think that this part is whats causing the problem.
Vector3 playerPosition = transform.position;
playerPosition.x = playerPosition.x + movement*speed *Time.deltaTime;
transform.position = playerPosition;
I have tried various other scripts using rigibodies but that just causes my character to slowly move downwards and not be able to move side to side.
Please help. Thank you.
