I am making a 2D game in Unity. So I used trasform.position += movePos type code to move my player when specific key pressed. I also made some animations. Player is not moving still animation is performing. Everything was working fine before I made the jump animation. But now it isn't working. Can someone suggest me what to do. I hadn't made a repository of code in github so I can't share it.
Here you can watch video what is happening:- https://1drv.ms/v/s!AnUoIDNJEoVSmQylzexBqmA1i8Ur?e=4FhJ5h
and here is my player controls code which is responsible for controls:-
using System.Collections;
using UnityEngine;
public class PlayerControls : MonoBehaviour
{
#region variables
// Private variables
private float speed = 15f;
[SerializeField]
private bool isOnGround;
private Quaternion leftMoveRotate = new Quaternion(0f, 180f, 0f, 1f);
private Quaternion rightMoveRotate = new Quaternion(0f, 0f, 0f, 1f);
// Public Variables
public Animator playerAnimator;
#endregion
private void OnTriggerEnter2D(Collider2D other)
{
if (other.CompareTag("ground"))
{
isOnGround = true;
}
}
private void Update()
{
float horizontalInput = Input.GetAxis("Horizontal");
if (horizontalInput > 0)
{
DInput();
}
if (horizontalInput < 0)
{
AInput();
}
playerAnimator.SetFloat("isRunning", Mathf.Abs(horizontalInput));
if (Input.GetKeyDown(KeyCode.Space) || Input.GetKeyDown(KeyCode.LeftShift))
{
Jump();
}
}
private void Jump()
{
if (isOnGround)
{
transform.position += new Vector3(0f, 4f, 0f); // Jump code
isOnGround = false;
}
}
private void DInput()
{
transform.rotation = rightMoveRotate;
transform.position += new Vector3(0.5f, 0f, 0f) * speed * Time.fixedDeltaTime;
}
private void AInput()
{
transform.rotation = leftMoveRotate;
transform.position -= new Vector3(0.5f, 0f, 0f) * speed * Time.fixedDeltaTime;
}
}
I also have a code of camera following the player and here is that:-
using UnityEngine;
public class CameraFollow : MonoBehaviour
{
public Transform player;
public float offSetX = 5f;
public float offSetY = 2.5f;
private void FixedUpdate() {
Vector3 tempPos = transform.position;
tempPos.x = player.position.x;
tempPos.x += offSetX;
tempPos.y = player.position.y;
tempPos.y += offSetY;
transform.position = tempPos;
}
}
and if I remove jump animation from Animator all control works fine. Here is video you can check:-
https://1drv.ms/v/s!AnUoIDNJEoVSmQ2k_o7Fbs0J5_8d?e=tJlayZ
One thing you might have messed up and is not showing in script, is you recorded transform position change in your animation and animation is messing with position.

I have two players in the script above because I tried to move it in two ways but nothing worked
So I tried to set the object to vector3 and try to move the player to the object, so nothing comes out
I need teleport player when he triger the collider. Debug.Log work but transform.position dont work.
Its dosent work from this script -> fpscontroller

no matter what I do with my code, the Player doesn't seem to want to jump. Everything is referenced correctly in Unity and the code is hopefully error free. I've also checked to see if the Input System is corresponding to what I've got pressed. The only thing I can think of is the force isn't strong enough for the player to lift off of the ground, due to the high gravity (7f). But I lowered the gravity and nothing changed. Thanks for the help in advance.

The code works fine and the player jumps and moves without problems
Make sure to perform these steps inside Unity Engine
Inside the player you must add
Rigidbody2D
Box Collider2D
the code
Inside the code you must specify
Ground Layer : "Ignore Raycast"
Ground Check : "The ground the player is walking on"
And inside the ground must be added
Layer : "Ignore Raycast"
Component: "Box Collider2D"
As in these pictures
Player
enter image description here
Ground
enter image description here
The code worked. The ground check had a collider on it, when it wasn't necessary. The ground check in reality was inside the player.
I am learning Unity, 3d free look camera and no errors, the only problem is the face and hands of the character doesn't rotate, only the armor of the character is rotating when I go to a different direction. I am using a free viking prefab from unity asset store as game character, the prefab has two child the face&hands and the armor. On the line "child = transform.GetChild(0).transform;" when I replace the 0 with 1 only the face and hands rotate. How can I make the whole prefab rotate when moving around?

I'm making a 2D platformer with Unity. I used this tutorial to write this code but changed it a little bit. I want to support both keyboard and gamepad, so I use the new Input System. I've defined three variables called GroundedRememeber, JumpPressedRemember and JumpPressedRememberTime and basically they work like timers and check if the player leaves the ground and then the player can jump when he is near the ground without need to touch it and I want to use it instead of famous "groundCheck". But the problem is that these timers are not working and the player can jump forever even in the air when I press jump button rapidly. Also, as you can see, I added a LayerMask named "groundLayers" for the player to jump only on this type of objects but when I choose "Ground" in the "groundLayers" slot in the Inspector, the player can't jump anymore.

If you know how much the player jumps for, then try maybe adding a delay to the next jump
Maybe using the Invoke() function ur just using Coroutines if you know how to use them.
But i would still recommend using a Ground Check since it's practical and just easier and i don't see a reason why you wouldn't use it.
So i'm having issues with a script I have, what it does is basically rotate the player graphics depending on where the mouse is aiming at. This works fine and as intended but my issue is that when I want to shoot on the opposite direction, that being the Left direction, it shoots the player instead of where it's aiming at.
I've decided to record a small video to show the problem.
https://streamable.com/02zqz
Here's the code to both the rotation and weapon script.
Rotating
public class Rotating : MonoBehaviour
{
public PlayerController player;
public float x;
public Vector3 flipArm;
void Start()
{
x = transform.localScale.x;
flipArm = transform.localScale;
player = GetComponentInParent<PlayerController>();
}
void Update()
{
Vector3 difference = Camera.main.ScreenToWorldPoint(Input.mousePosition ) - transform.position;
difference.Normalize();
float rotZ = Mathf.Atan2(difference.y, difference.x) * Mathf.Rad2Deg;
transform.rotation = Quaternion.Euler(0f, 0f, rotZ + 0);
if(difference.x >= 0)
{
transform.rotation = Quaternion.Euler(0f, 0f, rotZ);
player.armRight = true;
}
else
{
transform.rotation = Quaternion.Euler(0f, 0f, rotZ+180);
player.armRight = false;
}
}
}
Weapon
public class Weapon : MonoBehaviour
{
public float shootDelay = 0;
public float damage = 1;
public LayerMask whatToHit;
public Transform firePoint;
public GameObject bullet;
// Start is called before the first frame update
void Start()
{
firePoint = transform.Find("FirePoint");
}
// Update is called once per frame
void Update()
{
shootDelay += Time.deltaTime;
if(shootDelay >= 0.1f)
{
if(Input.GetMouseButton(0))
{
shootDelay = 0;
Shot();
}
}
}
public void Shot()
{
Vector2 mousepos = new Vector2(Camera.main.ScreenToWorldPoint(Input.mousePosition).x, Camera.main.ScreenToWorldPoint(Input.mousePosition).y);
Vector2 firepointpos = new Vector2(firePoint.position.x, firePoint.position.y);
Instantiate(bullet, firepointpos, transform.rotation);
Debug.DrawLine(firepointpos, (mousepos - firepointpos) * 100, Color.cyan);
}
}
Try this:
transform.rotation = Quaternion.LookRotation ( end - start );
Also don't forget to check where the player is facing because you don't want to shoot from back. Using the above euler angles, one side is 90 and another 270 degrees in y component.
