I have first person shooter. It's work when I rotate the camera at first (right part of the screen) and then use joystick for movement (left part of the screen). But if I use joystick for movement and then rotate the camera - player move and camera rotate by joystick, not by camera rotation zone. How to fix it?

I am doing my Computer Science A-Level NEA and I want to program a teleport for my player character to use in these circumstances:
The direction of the teleport is controlled by the left mouse button
The player can only teleport once until they touch the ground again
If the player teleports through enemies then those enemies will be instantly killed.
The third one isn't too important at the moment as the 2nd condition isn't working properly.
using System.Collections; using System.Collections.Generic; using
UnityEngine;
public class Teleport : MonoBehaviour {
public Vector2 screenPosition;
public Vector2 worldPosition;
private CharacterController2D characterController2D;
public bool canTeleport = true;
void Awake()
{
characterController2D = GetComponent<CharacterController2D>();
}
public void t_PORT()
{
bool ground_check = characterController2D.m_Grounded;
if (canTeleport = true && Input.GetMouseButtonDown(0))
{
screenPosition = Input.mousePosition;
worldPosition = Camera.main.ScreenToWorldPoint(screenPosition);
transform.position = worldPosition;
while (ground_check = false)
{
if (ground_check = false)
{
canTeleport = false;
}
else
{
canTeleport = true;
}
}
}
} }
Here is the code for the teleport. It works by taking the on-screen position of the mouse when clicked, translating it into an in-game position and changing the player's position to that of the mouse's.
I took a boolean value from my Character Controller called m_grounded which checks to see if the player is currently touching the ground. I thought that if the player has already teleported I could use a while loop (it would loop on the condition that m_grounded is false and break when the player touches the ground allowing them to teleport again). The first time I tried this it didn't work as I had the code in an Update Class and when I would teleport the game would freeze. I then put it into it's own class called t_Port (which you can see above) but then the player wouldn't teleport at all. I decided to put it in a FixedUpdate class which allowed the player to teleport once more but the player could teleport an infinite amount of times (which I do not want).
The script for my character controller is here:

I would like for my player character to teleport once before having to touch the ground to be able to teleport again.
I appreciate the thouroughness of posting all relevant code, but the error is in the very first snippet:
while (ground_check = false)
{
if (ground_check = false)
{
...
One equals sign is an assignment, two is an equality check:
while (ground_check == false)
{
if (ground_check == false)
{
...

I am new to unity. Recently, I have started making a survival fps game, there, I have 1 enemy, when I kill him, it will spawn more enemies. However, the spawned only move, but not shoot. Although, I have attached a script to it. here are all my code.

// StartCoroutine(EnemySpawner());
Destroy(collision.gameObject);
}
}
Pls help me, I am stuck in this for almost 3 days..
You didn't call the function
In your first script (prefab_shooting-) You didn't call the Shoot() function.
So i'm making a Platformer game but my player can only jump and crouch. Everytime I want to walk, my player just stay here and don't move. Everything is okay in the input manager and i'm using a character controller 2D. For the movement, I have made a little script named PlayerMovement. I'm currently using Unity 2019.3.14f1.

Its quite easy. you need to add these two scripts to the gameobject (not the ball but the one which is used to shoot the ball something like a gun)

}
public void OnPointerUp(PointerEventData e) {
onUp.Invoke(e);
}
}
[System.Serializable]
public class TouchEvent : UnityEvent<PointerEventData> {}
Shooter.cs
public void TryBeginAim(PointerEventData e) {
if(canShoot) {
initialTouchPos = e.position;
}
}
public void TryAim(PointerEventData e) {
if(canShoot) {
direction = initialTouchPos - e.position;
float mag = (initialTouchPos - e.position).magnitude;
float scale = Mathf.Clamp(mag/maxMagnitude, scaleThreshold, 1f);
angle = Mathf.Atan2(direction.y,direction.x) * Mathf.Rad2Deg + 90f;
aim.transform.rotation = Quaternion.AngleAxis(angle, Vector3.forward);
aim.transform.localScale = Vector3.one * scale;
aim.SetActive(e.position.y < initialTouchPos.y);
}
}
public void TryShoot(PointerEventData e) {
if(canShoot && aim.activeInHierarchy) {
canShoot = false;
StartCoroutine(ShootRoutine(balls));
}
aim.SetActive(false);
}
private IEnumerator ShootRoutine(int b) {
// write code to start shooting balls.
}
Then connect the touch events with the methods like this:
1. OnPointerClick => TryBeginAim
2. OnPointerDown => TryAim
3. OnPointerUp => TryShoot
That's All !!
I hope this helps to solve this issue. Enjoy!
I have the following script
public class SpeedUp : MonoBehaviour {
public Rigidbody2D ball;
void OnTriggerEnter2D(Collider2D col)
{
if (col.tag == "Ball") {
ball.AddForce(Vector2.left * 1000f);
Debug.Log("ABC");
}
}
}
and every time I run my game, the Debug.Log("ABC") prints ABC in the console, but the Rigidbody doesn't move, it stays as it is. Can someone explain me why, because I don't understand why does the console print work and the Rigidbody doesn't move
This is the code for the Ball
public class Ball : MonoBehaviour {
public Rigidbody2D rb;
public Rigidbody2D hook;
public float releaseTime = 0.15f;
private bool isPressed = false;
void Update()
{
if (isPressed)
{
Vector2 mousePos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
if (Vector3.Distance(mousePos, hook.position) > 2.5f)
{
rb.position = hook.position + (mousePos - hook.position).normalized * 2.5f;
}
else
{
rb.position = mousePos;
}
}
}
void OnMouseDown()
{
isPressed = true;
rb.isKinematic = true;
}
void OnMouseUp()
{
isPressed = false;
rb.isKinematic = false;
StartCoroutine(Release());
}
IEnumerator Release()
{
yield return new WaitForSeconds(releaseTime);
GetComponent<SpringJoint2D>().enabled = false;
this.enabled = false;
}
}
The Rigidbody doesn't move may be it's need to getComponenrt()
So, add void Start() method in your the script
public class SpeedUp : MonoBehaviour {
public Rigidbody2D ball;
void Start()
{
ball = ball.GetComponent<Rigidbody2D>();
}
void OnTriggerEnter2D(Collider2D col)
{
if (col.tag == "Ball") {
ball.AddForce(Vector2.left * 1000f);
Debug.Log("ABC");
}
}
}
