The sprite doesnt seems to be jumping

i am following a brackeys tutorial, the sprite is moving left right but not jumping. "Jump" is working fine but the results are not present in the gameview.it references a script provided by brackeys but i dont whether thats the problem.
Here is the code
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class player_movemnt : MonoBehaviour
{
public CharacterController2D controller;
float horizontal_movement =0f;
public float run_speed = 60f;
bool jump = false;
void Update()
{
horizontal_movement = Input.GetAxisRaw("Horizontal")*run_speed;
if(Input.GetButtonDown("Jump"))
{
jump = true;
Debug.Log("l");
}
}
void FixedUpdate()
{
//move character
controller.Move(horizontal_movement*Time.fixedDeltaTime,false, jump);
jump= false;
}
}
here is the CharacterControl2D scrip
using UnityEngine;
using UnityEngine.Events;
public class CharacterController2D : MonoBehaviour
{
[SerializeField] private float m_JumpForce = 400f; // Amount of force added when the player jumps.
[Range(0, 1)] [SerializeField] private float m_CrouchSpeed = .36f; // Amount of maxSpeed applied to crouching movement. 1 = 100%
[Range(0, .3f)] [SerializeField] private float m_MovementSmoothing = .05f; // How much to smooth out the movement
[SerializeField] private bool m_AirControl = false; // Whether or not a player can steer while jumping;
[SerializeField] private LayerMask m_WhatIsGround; // A mask determining what is ground to the character
[SerializeField] private Transform m_GroundCheck; // A position marking where to check if the player is grounded.
[SerializeField] private Transform m_CeilingCheck; // A position marking where to check for ceilings
[SerializeField] private Collider2D m_CrouchDisableCollider; // A collider that will be disabled when crouching
const float k_GroundedRadius = .2f; // Radius of the overlap circle to determine if grounded

{
bool wasGrounded = m_Grounded;
m_Grounded = false;
// The player is grounded if a circlecast to the groundcheck position hits anything designated as ground
// This can be done using layers instead but Sample Assets will not overwrite your project settings.
Collider2D[] colliders = Physics2D.OverlapCircleAll(m_GroundCheck.position, k_GroundedRadius, m_WhatIsGround);
for (int i = 0; i < colliders.Length; i++)
{
if (colliders[i].gameObject != gameObject)
{
m_Grounded = true;
if (!wasGrounded)
OnLandEvent.Invoke();
}
}
}
public void Move(float move, bool crouch, bool jump)
{
// If crouching, check to see if the character can stand up
if (!crouch)
{
// If the character has a ceiling preventing them from standing up, keep them crouching
if (Physics2D.OverlapCircle(m_CeilingCheck.position, k_CeilingRadius, m_WhatIsGround))
{
crouch = true;
}
}
//only control the player if grounded or airControl is turned on
if (m_Grounded || m_AirControl)
{
// If crouching
if (crouch)
{
if (!m_wasCrouching)
{
m_wasCrouching = true;
OnCrouchEvent.Invoke(true);
}
// Reduce the speed by the crouchSpeed multiplier
move *= m_CrouchSpeed;
// Disable one of the colliders when crouching
if (m_CrouchDisableCollider != null)
m_CrouchDisableCollider.enabled = false;
} else
{
// Enable the collider when not crouching
if (m_CrouchDisableCollider != null)
m_CrouchDisableCollider.enabled = true;
if (m_wasCrouching)
{
m_wasCrouching = false;
OnCrouchEvent.Invoke(false);
}
}
// Move the character by finding the target velocity
Vector3 targetVelocity = new Vector2(move * 10f, m_Rigidbody2D.velocity.y);
// And then smoothing it out and applying it to the character
m_Rigidbody2D.velocity = Vector3.SmoothDamp(m_Rigidbody2D.velocity, targetVelocity, ref m_Velocity, m_MovementSmoothing);
// If the input is moving the player right and the player is facing left...
if (move > 0 && !m_FacingRight)
{
// ... flip the player.
Flip();
}
// Otherwise if the input is moving the player left and the player is facing right...
else if (move < 0 && m_FacingRight)
{
// ... flip the player.
Flip();
}
}
// If the player should jump...
if (m_Grounded && jump)
{
// Add a vertical force to the player.
m_Grounded = false;
m_Rigidbody2D.AddForce(new Vector2(0f, m_JumpForce));
}
}
private void Flip()
{
// Switch the way the player is labelled as facing.
m_FacingRight = !m_FacingRight;
// Multiply the player's x local scale by -1.
Vector3 theScale = transform.localScale;
theScale.x *= -1;
transform.localScale = theScale;
}
}
i am completely dumbfounded with this problem.

If you're using a separate class to handle your movement, it's always ideal to include it alongside your question. So others wont have to search for it.
Your code appears okay, at least based on the tutorial you've mentioned. Double-check that them_GroundCheck GameObject of CharacterController2D is on the ground rather than on the bottom of the player, as that's responsible for ensuring you can jump in the first place.
public CharacterController2D characterController;
public float runSpeed = 60f;
private float _horizontalMovement;
private bool _jump;
private void Update()
{
_horizontalMovement = Input.GetAxisRaw("Horizontal") * runSpeed;
if (Input.GetButtonDown("Jump"))
{
_jump = true;
}
}
private void FixedUpdate()
{
characterController.Move(_horizontalMovement * Time.fixedDeltaTime, false, _jump);
_jump = false;
}
I'd recommend working backwards and ensuring your CharacterController2D is set up correctly to support the jump, including any attributes you need to add in the inspector window. Such as a reference to GroundCheck and its LayerMask.

Why sometimes the player is making a circle movement around the target?

The main goal of the script in this case is when the player is getting too close to the fire to slowly stop walking automatic wait some seconds then automatic rotate and start walking again and then stop again slowly.
The script is working when the player is entering the collider area this is the target variable position so the player is rotating back to where he was entered from.
The idea is to make something nice to prevent from the player to get into the fire. but i'm facing two problems.
The first problem is that in the script i'm using a box collider as the area to prevent from the player to get closer to the fire and it's hard to dynamic change the collider area shape to cover all sides.
This is a screenshot of the collider area :
I marked to possible places if the player is coming from closer to the fire when he enter/exit the collider area he is already inside the fire and it's hard to change the collider size and scale to cover this places too.
I wonder if using distance check instead of the box collider will be easier ? and if it is how to change the script to use distance check instead the box collider trigger enter and exit events ?
The second problem is that sometimes when the player got close to the fire and then rotating back outside the collider area when he exit at that point(position) the player is making a walking circle around the target position and then continue outside. not sure why the player is making sometimes a moving around the target point ?
The script is attached to the player :
using System.Collections;
using System.Collections.Generic;
using TMPro;
using UnityEngine;
using UnityStandardAssets.Characters.ThirdPerson;
public class SpreadedFireDistanceCheck : MonoBehaviour
{
public Vector3 target;
public float rotationSpeed;
public GameObject descriptionTextImage;
public TextMeshProUGUI text;
public Transform player;
private Animator anim;
private ThirdPersonUserControl thirdPersonUserControl;
private bool startRotBack = false;
private bool rot = false;
private bool doOnce = true;
private bool getTargetPos = false;
float angle = 10;
// Start is called before the first frame update
void Start()
{
anim = player.GetComponent<Animator>();
thirdPersonUserControl = player.GetComponent<ThirdPersonUserControl>();
}
// Update is called once per frame
void Update()
{
if (startRotBack)
{
if (doOnce)
{
anim.SetTrigger("Idle Exit");
StartCoroutine(WaitTime());
doOnce = false;
}
if (rot)
{
anim.SetBool("Walk", true);
if (Vector3.Angle(player.transform.forward, target - player.transform.position) > angle)
{
Vector3 dir = target - player.transform.position;
Quaternion lookRotation = Quaternion.LookRotation(dir);
Vector3 rotation = Quaternion.Lerp(player.transform.rotation, lookRotation, Time.deltaTime * rotationSpeed).eulerAngles;
player.transform.rotation = Quaternion.Euler(0f, rotation.y, 0f);
}
}
}
}
private void OnTriggerExit(Collider other)
{
if (other.name == "kid_from_space")
{
if (rot)
{
rot = false;
anim.SetBool("Walk", false);
anim.SetTrigger("Idle Enter");
thirdPersonUserControl.enabled = true;
getTargetPos = false;
}
}
}
private void OnTriggerEnter(Collider other)
{
if (other.name == "kid_from_space")
{
if (getTargetPos == false)
{
target = player.transform.position;
getTargetPos = true;
}
descriptionTextImage.SetActive(true);
text.text = "This flames are so hot, i better stay away.";
thirdPersonUserControl.enabled = false;
doOnce = true;
startRotBack = true;
}
}
private IEnumerator WaitTime()
{
yield return new WaitForSeconds(5f);
text.text = "";
descriptionTextImage.SetActive(false);
rot = true;
}
}
In general the script is working but this two problem i mentioned above is hard to solve.
The player have this components :
Animator , Rigidbody , Capsule Collider , Third Person User Control (Script) , Third Person Character (Script)

How to have a rigidbody object "ride" a falling platform, while still being able to move horizontally

I'm making a 2D game in Unity, which has falling platforms that the player can "ride" down. I want the player to still be able to move left or right (ie horizontally) while standing on a falling platform. Without additional code, just using the Rigidbody physics, the player does fall along with the platform, but the falling is choppy, and the game doesn't always see the player is standing on the platform (important because the player can only jump while standing on something).
I've tried setting the player object's transform.translate, which prevents the player from moving left or right as long as it is touching the platform. I've also tried setting the player object's transform.parent to the platform's transform, but that "glues" the player in place to the platform, preventing even jumping. I've also tried searching for a solution/example, and there are plenty of examples for riding a left-right moving platform, but I haven't been able to get those examples to work for a falling platform.
Here is the script controlling the players left-right movement and jumping. This is attached to the player object:
public class Player : MonoBehaviour
{
public float jumpForce = 5;
public float horizontalSpeed = 0.1F;
public LayerMask whatIsGround;
private Rigidbody2D rb2d;
private Collider2D myCollider;
private bool grounded;
private float lastHorizontalInput;
void Start()
{
rb2d = GetComponent<Rigidbody2D>();
myCollider = GetComponent<Collider2D>();
}
void Update()
{
// If the player is trying to jump, only do so if the player is on a platform
grounded = Physics2D.IsTouchingLayers(myCollider, whatIsGround);
if (Input.GetKeyDown(KeyCode.Space) && grounded)
{
rb2d.velocity = new Vector2(rb2d.velocity.x, jumpForce);
}
MoveHorizonltally();
}
private void MoveHorizonltally()
{
float horizontalVelocity;
float horizontalInput = Input.GetAxis("Horizontal");
horizontalVelocity = GetHorizontalVelocity(horizontalInput);
if (horizontalVelocity != 0)
{
rb2d.position = new Vector2(rb2d.position.x + horizontalVelocity, rb2d.position.y);
}
}
private float GetHorizontalVelocity(float horizontalInput)
{
// Default to no horizontal motion
float result = 0;
bool leftPressed = Input.GetKey(KeyCode.A) || Input.GetKey(KeyCode.LeftArrow);
bool rightPressed = Input.GetKey(KeyCode.D) || Input.GetKey(KeyCode.RightArrow);
// Only a left key is being pressed; the player is going left
if (leftPressed && !rightPressed)
{
result = -1 * horizontalSpeed;
}
// Only a right key is being pressed; the player is going right
else if (rightPressed && !leftPressed)
{
result = horizontalSpeed;
}
// Both keys are being pressed
else if (leftPressed && rightPressed)
{
// The most recent key press gets priority; ignore the oldest key press
if (lastHorizontalInput < 0)
{
// Oldest key pressed is a left direction, so go right
result = horizontalSpeed;
}
else
{
// Oldest key pressed is a right direction, so go left
result = -1 * horizontalSpeed;
}
}
lastHorizontalInput = horizontalInput;
return result;
}
}
Here is the script responsible for making the platform fall. This is attached to the platform object:
public class PlatformFalling : MonoBehaviour
{
public float fallSpeed;
private GameObject player;
public void Start()
{
player = GameObject.FindGameObjectWithTag("Player");
}
// Update is called once per frame
void Update()
{
bool playerIsOnPlatform = player.GetComponent<Collider2D>().IsTouching(GetComponent<Collider2D>()); ;
Vector2 fallDistance = Vector2.down * fallSpeed;
transform.Translate(fallDistance);
if (playerIsOnPlatform)
{
player.transform.Translate(fallDistance);
}
}
}

How do I change a GameObject's rotation equal to my player camera's rotation?

Im working on a first person shooter. I have an aim function, which puts the pistol right in front of the camera, to make it look like your holding it in front of you. Im trying to make it so the pistol will also rotate with the camera on the Z axis, so that way the pistol wont stay still, because that looks odd and gets in the way. To do this, I tried this:
GPR.gun.transform.rotation = Quaternion.Euler(0, 0, plrCam.transform.rotation.z);, however this ends up rotating the gun very slightly around the z axis, and mainly rotating it around the y axis whenever I move my camera. I am a beginner programmer in Unity so please try to make answers more digestible to beginners so I can understand it. Here is my full script:
using System.Collections.Generic;
using UnityEngine;
public class PistolFire : MonoBehaviour
{
//Gun Properties
public float range = 50f;
public float damage = 10f;
//Sensitivity decrease for looking down the sights
public float downSights = 5f;
//Other vars
private playerGunControls playerGun;
private GameObject plrCam;
private Camera fpsCam;
private ParticleSystem muzzleFlash;
private GameObject impactEffect;
private bool aimed = false;
private GameObject aimPos;
private GunPickupRaycast GPR;
private GameObject handPos;
private GameObject Player;
// Start is called before the first frame update
void Start()
{
//Getting objects because gun is instantiated, so this is necessary
plrCam = GameObject.Find("Player Camera");
playerGun = plrCam.GetComponent<playerGunControls>();
fpsCam = plrCam.GetComponent<Camera>();
muzzleFlash = GetComponentInChildren<ParticleSystem>();
impactEffect = GameObject.Find("Impact Effect");
aimPos = GameObject.Find("aimPos");
GPR = plrCam.GetComponent<GunPickupRaycast>();
handPos = GameObject.Find("Hand Pos");
Player = GameObject.Find("Player");
}
// Update is called once per frame
void Update()
{
//Check for shoot button down
if (Input.GetButtonDown("Fire1"))
{
if (playerGun.holding == "Pistol")
{
Shoot();
}
}
//Check if aim button down
if (Input.GetButton("Fire2"))
{
if (playerGun.holding == "Pistol")
{
Aim();
}
}
//Check if no longer aiming to reset to normal
if (aimed == true && !(Input.GetButton("Fire2")))
{
Unaim();
}
}
void Shoot()
{
muzzleFlash.Play();
RaycastHit hit;
if(Physics.Raycast(plrCam.transform.position, plrCam.transform.forward, out hit, range))
{
Debug.Log(hit.transform.name);
Health health = hit.transform.GetComponent<Health>();
if (health != null)
{
health.TakeDamage(damage);
}
//Instantiate the Impact Effect
GameObject IE = Instantiate(impactEffect, hit.point, Quaternion.identity);
Destroy(IE, 1.5f);
}
}
void Aim()
{
aimed = true;
Debug.Log("Aiming");
GPR.gun.transform.position = aimPos.transform.position;
GPR.gun.transform.rotation = Quaternion.Euler(0, 0, plrCam.transform.rotation.z);
}
void Unaim()
{
GPR.gun.transform.position = handPos.transform.position;
Debug.Log("No longer aiming");
aimed = false;
}
}

I fixed my problem by making the gun a child of my camera instead of a child of my player.

This is first time that I have used cross platform input
so I don't even know why this error is showing

Sorry to Bother you guys.
I think i found my error in this code
actually i mistakenly write
using UnityStandardAssets.CrossCrossPlatformInput;
instead of
using UnityStandardAssets.CrossPlatformInput;
that's why it's showing error Unknown Namespace Under Standard Unity Assests
Actually I am new to Unity and also new to game development
i think that's why this problem happen

also, you need to use a compiler definition as shown, i was stuck on it for a long time, but found it written in the guidelines that come along with standard asset package..
