I'm getting this error in Unity after pressing the relative "eastButton":
Error: MissingReferenceException while executing 'canceled' callbacks of 'Gameplay/Block[/DualShock4GamepadHID/buttonEast,/Mouse/rightButton]'
UnityEngine.InputSystem.InputActionAsset:OnDestroy () (at Library/PackageCache/com.unity.inputsystem#1.0.2/InputSystem/Actions/InputActionAsset.cs:794)
I'm attempting to set up 'block' functionality within my game which simply locks the player's movement then disables my "canBeHit" bool which will then put the player in a state where they cannot be hit, however upon interacting with the eastButton all player movement is completely locked preventing you from moving, however rotation is still possible. Another part I'd like to note is that I'm working with the Mirror package so I can network my game, unsure if this could also be causing problems. Would really appreciate if someone could point out where I've gone wrong, I'd be very grateful.

If any additional information is needed to solve my problem I'm more than happy to submit any necessary info.
I created a function in Unity that is supposed to allow the character to climb. It creates two problems, first of all it somehow interacts with the general movement function. When the character starts running their animation won't stop even when the player isn't moving them. Second of all the character can climb up and down the ladder but won't get off them, even though technically the logic is constructed in such a way that they should just go back to their normal state.
I have tried turning off the climb function in the Update() function so I know the running problem is caused by it, because it works fine without it.
private void Climb()
{
RaycastHit2D ladder = Physics2D.Raycast(transform.position, Vector2.up, 5, whatIsLadder);
float hDirection = Input.GetAxisRaw("Horizontal");
float vDirection = Input.GetAxisRaw("Vertical");
if (ladder.collider != null)
{
if (vDirection > 0.1f)
{
isClimbing = true;
}
}
else
{
if (hDirection > 0.1f)
{
isClimbing = false;
}
}
if (isClimbing == true && ladder.collider != null)
{
rb.gravityScale = 0;
rb.velocity = new Vector2(rb.velocity.x, climbSpeed * vDirection);
if (Mathf.Abs(vDirection) > 0.1f)
{
anim.speed = 1f;
}
else
{
anim.speed = 0f;
}
}
else
{
rb.gravityScale = naturalGravity;
}
}
I'll also give a link to the whole PlayerController script since that might help some people:
https://github.com/Pacal2/Platformer/blob/master/Assets/Scripts/PlayerController.cs
Try resetting the velocity on the rigidbody when he stops climbing, near the end of the function:
//....
{
rb.gravityScale = naturalGravity;
}
into:
{
rb.gravityScale = naturalGravity;
rb.velocity = new Vector2(0.0f, 0.0f);
}
this code also looks suspect
if (ladder.collider != null)
{
if (vDirection > 0.1f)
{
isClimbing = true;
}
}
else
{
if (hDirection > 0.1f)
{
isClimbing = false;
}
}
change to:
if (ladder.collider != null)
{
if (vDirection > 0.1f || vDirection < -0.1f) //if allowed to climb down
{
isClimbing = true;
}
if (hDirection > 0.1f || hDirection < -0.1f) //moving left
{
isClimbing = false;
}
}
for animation speed try:
anim.speed = rb.velocity.x;
I lost a lot of time trying to find what is the problem in code but I can not find the solution why my code is not triggered.
In my previous game when I implemented this code it worked perfectly, now when i implement into new game this same code for touch movement it doesn't work.
I tried to debug the code and put Debug.Log into Update method and when i swipe over screen it doesn't even get trigger.
This is the code:
int left = 0;
int right = 0;
int maxLeftCycles = 5;
int maxRightCycles = 5;
void Start()
{
//touch
left = maxLeftCycles;
right = maxRightCycles;
}
private void Update()
{
timer += Time.deltaTime;
if (Input.GetKeyUp(KeyCode.RightArrow) ||
Swipe.swipe == Swipe.SwipeDirection.right)
{
Swipe.ResetSwipe();
right = 0;
}
if (Input.GetKeyUp(KeyCode.LeftArrow) ||
Swipe.swipe == Swipe.SwipeDirection.left)
{
Swipe.ResetSwipe();
left = 0;
}
}
void FixedUpdate()
{
if (left < maxLeftCycles && !isMoving)
{
desiredPos = transform.position + Vector3.left * 1.52f;
isMoving = true;
left++;
}
if (right < maxRightCycles && !isMoving)
{
desiredPos = transform.position - Vector3.right * 1.52f;
isMoving = true;
right++;
}
if (isMoving)
{
transform.position = Vector3.MoveTowards(transform.position, desiredPos, moveSpeed * Time.deltaTime);
// this == is true if the difference between both
// vectors is smaller than 0.00001
if (transform.position == desiredPos)
{
isMoving = false;
transform.position = desiredPos;
}
}
}
I put Debug.Log in this code and in vector3.right and left but it never get triggered.
if (Input.GetKeyUp(KeyCode.RightArrow) ||
Swipe.swipe == Swipe.SwipeDirection.right)
{
Debug.Log("This is traacked");
Swipe.ResetSwipe();
right = 0;
}
if (Input.GetKeyUp(KeyCode.LeftArrow) ||
Swipe.swipe == Swipe.SwipeDirection.left)
{
Debug.Log("This is traacked");
Swipe.ResetSwipe();
left = 0;
}
This is the code for Swipe script
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Swipe : MonoBehaviour
{
private float fingerStartTime = 0.0f;
private Vector2 fingerStartPos = Vector2.zero;
private bool isSwipe = false;
private float minSwipeDist = 50.0f;
private float maxSwipeTime = 0.5f;

}

{
swipe = SwipeDirection.none;
}
// Update is called once per frame
void Update()
{
if (Input.touchCount > 0)
{
foreach (Touch touch in Input.touches)
{
switch (touch.phase)
{
case TouchPhase.Began:
/* this is a new touch */
isSwipe = true;
fingerStartTime = Time.time;
fingerStartPos = touch.position;
break;
case TouchPhase.Canceled:
/* The touch is being canceled */
isSwipe = false;
break;
case TouchPhase.Ended:
float gestureTime = Time.time - fingerStartTime;
float gestureDist = (touch.position - fingerStartPos).magnitude;
if (isSwipe && gestureTime < maxSwipeTime && gestureDist > minSwipeDist)
{
Vector2 direction = touch.position - fingerStartPos;
Vector2 swipeType = Vector2.zero;
if (Mathf.Abs(direction.x) > Mathf.Abs(direction.y))
{
// the swipe is horizontal:
swipeType = Vector2.right * Mathf.Sign(direction.x);
}
else
{
// the swipe is vertical:
swipeType = Vector2.up * Mathf.Sign(direction.y);
}
if (swipeType.x != 0.0f)
{
if (swipeType.x > 0.0f)
{
// MOVE RIGHT
swipe = SwipeDirection.right;
}
else
{
// MOVE LEFT
swipe = SwipeDirection.left;
}
}
if (swipeType.y != 0.0f)
{
if (swipeType.y > 0.0f)
{
// MOVE UP
swipe = SwipeDirection.up;
}
else
{
// MOVE DOWN
swipe = SwipeDirection.down;
}
}
}
break;
}
}
}
}
}
The code in Update method for swipe input which I debug never get called or never work for me.I can not understand what i am doing wrong because the same code actually works in my previous game.
Thank you so much for reading my question I hope there will be some guy who can help me to solve this issue.
If it worked as is before hand in another project I would make sure that you are attaching the script to a game object. If it is attached to a game object make sure that it is not marked as inactive and that you aren't turning the object to inactive somewhere else in your scripts.
If neither of these are the case I would also try removing the script from the object and then reattaching it, and if that still doesn't work try deleting the object the script is attached to (if possible) and then recreate it and reattach the script.
I am beginner of C# unity. I was searching the solution to swap cube with add force in 8 direction, but I could not find anything. I am really confused that how can I do this. Someone please guide me in this regard. Any code example or tutorial for solving the problem will be appreciated.
Thanks in advance.
Here is my code:
using UnityEngine;
using System.Collections;
public class Swaping1 : MonoBehaviour {
int swipeIndex = -1; //index of first detected swipe to prevent multiple swipes
public Vector2 startPos; //starting position of touch
public float minSwipeDist;

public float LeftSwape;
public float RightSwape;
public GUIButtons GUIButtonsObj;
// Use this for initialization
void Start () {
GUIButtonsObj=GetComponent<GUIButtons>();
}
public void swipe()
{
for (int i = 0; i < Input.touchCount; i++) {
Touch touch = Input.touches [i];
switch (touch.phase) {
case TouchPhase.Began:
if (swipeIndex == -1) {
swipeIndex = i;
startPos = touch.position;
}
break;
case TouchPhase.Moved:
if (i != swipeIndex)
break;
Vector2 direction = touch.position - startPos;
//vertical swipe
if (Mathf.Abs (direction.x) < Mathf.Abs (direction.y)) {
//swipe up
if ((touch.position.y - startPos.y) > minSwipeDist) {
//GUIButtonsObj.UpButton();
//transform.Translate(0f, UpSwape, 0f);
swipeIndex = -1;
}
//swipe down
else if ((touch.position.y - startPos.y) < -minSwipeDist) {
//transform.Translate(0f, -DownSwape, 0f);
//GUIButtonsObj.DownButton();
swipeIndex = -1;
}
}
//horizontal swipe
else {
//swipe right
if ((touch.position.x - startPos.x) < -minSwipeDist) {
//transform.Translate(-RightSwape, 0f, 0f);
GUIButtonsObj.LeftButton();
swipeIndex = -1;
}
//swipe left
else if ((touch.position.x - startPos.x) > minSwipeDist) {
// transform.Translate(LeftSwape, 0f, 0f);
GUIButtonsObj.RightButton();
swipeIndex = -1;
}
}
break;
}
}
}
// Update is called once per frame

{
swipe ();
}
}

Making a state machine AI "game" I have 3 states Movement, Combat, and View. They all work very well, now I'm making a flee (by the way if anyone has any good links to tutorials or info that they have off hand I would love that) state so I want to make all three previous state in their Idle mode. Which works perfectly when I have 1 AI. As soon as I put the rest (there is 6 total now) it will still only affect 1, but then after some time it will "release" I guess it the best term the script and just goes back to the three states that are supposed to be idle. I think that in my Coin script I am saying find and I think it needs to be something else, I'm just not sure if that's even right but based off of my previous experiences that's usually the case with Unity. I'll post some code, but here's some info that may help your eyes by not having to read through everything:
-I have a bool set up in my AIClass that is false until one of my gameobjects collides with a 'coin', and coin is jsut a gameobject i put in my game to test out my AI behaviors. When that bool is true, in my update in my AIClass(sorry it's at the very bottom of the script you can scroll down, but I had to put other code just in case I was doing something in that to cause my problem.) It sets the state of MovementState to Idle, CombatState to Idle and ViewState to Idle.
-Also, when that bool is false is the only time that the call for the transition of states occur. For example, normally the AI will search around trying to find player, if they find him they go near him, and if they are in a certain distance they fire. Pretty simple. The movement between those states happens at the end of each IENumerator when the 'NextMovementState()' or 'NextCombatState()' or 'NextViewState()' are called. So when the bool is true those should never be called, halting the AI from moving to another state other than Idle (to what it's set at when the bool is true in the update).
And this works fine when I have only 1 AI in the game.

You can use GameObject.FindObjectsOfType() or GameObject.FindGameObjectsWithTag
you can do that with store all the AIClass into array and then loop it become specific, so every enemy can affected
AIClass[] AIObject = GameObject.Find("Enemy").GetComponents<AIClass>();
foreach(AIClass a in AIObject ){
//do something with a
}
it should work.
