Unity - How to interrupt an ongoing animation by reversing it

Context
I got two transform states on a GameObject, A and B. I also have two animations that transition between the two states: A->B and B->A. The animations have different animation curves. The user can change the state of the GameObject at any moment.
What I want to achieve
If the state is changed while no animations are playing, the animations A->B and B->A are played normally. However, if the state is changed while an animation is playing, I want the current animation to reverse. For example, let's say that the user changes the state to B, and the animation A->B starts playing. Then the user suddenly changes back to state A before the animation A->B has finished. Here I want the A->B animation to start reversing to state A again, not playing the animation B->A.
What I currently have
I have tried to use Unity's Animator but have found no function to reverse an ongoing animation. I am open to using something else than the Animator but prefer not to use any external libraries.
Here is the current code I have with no reverse logic, only changing between state A and B
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class TestAnimation : MonoBehaviour
{
private Animator _animator;
private bool _isOpen = true;
void Awake()
{
this._animator = GetComponent<Animator>();
}
void Update()
{
if (Input.GetKeyDown(KeyCode.Space))
{
if (this._isOpen)
this._animator.SetTrigger("A");
else
this._animator.SetTrigger("B");
this._isOpen = !this._isOpen;
}
}
}

Found a solution now. Do not know if it is the most simple one but it works. What I did was to activate the animation by playing them via script, not using any triggers or floats in the animator as I tried first.
I also created two new animation states that are the reversed version of A->Band B->A. I looked at the normelizedTime variable in the animator to determine if any animation was currently playing. If so, I played the reversed animation at where it ended, see the code below.
Here is the animator with the different animation states:
And here is the code
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class TestAnimation : MonoBehaviour
{
private Animator _animator;
private bool _toggle = true;
private bool _isPlayingReverse = true;
void Awake()
{
this._animator = GetComponent<Animator>();
}
void Update()
{
if (Input.GetKeyDown(KeyCode.Space))
{
var animationTime = Mathf.Clamp(this._animator.GetCurrentAnimatorStateInfo(0).normalizedTime, 0.0f, 1.0f);
bool animationOngoing = animationTime < 1;
if (this._toggle)
{
if (animationOngoing && !this._isPlayingReverse)
{
this._animator.Play("A->B - Reversed", 0, 1 - animationTime);
this._isPlayingReverse = true;
}
else
{
this._animator.Play("B->A", 0, 1 - animationTime);
this._isPlayingReverse = false;
}
}
else
{
if (animationOngoing && !this._isPlayingReverse)
{
this._animator.Play("B->A - Reversed", 0, 1 - animationTime);
this._isPlayingReverse = true;
}
else
{
this._animator.Play("A->B", 0, 1 - animationTime);
this._isPlayingReverse = false;
}
}
this._toggle = !this._toggle;
}
}
}

Activating animation when within radius

I am trying to create a script for my enemy turret, but it is not going well. I have a couple animations of the turret being activated and deactivated. What I need is that based on the distance from the player, it plays either animation. So once it moves inside the detection radius it plays the activation animation and once it is outside it plays the deactivation animation. Most of the other ways I try require me to create an Animation Controller, which I have little experience in using. I want a simple way to play one animation once it is inside and play a different one when it is outside. I think there was a way to store the animation clip in the script, and then play it. I have attached my current script, so you know what I mean.
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class EnemyTurret : MonoBehaviour
{
public GameObject Player;
public float DistanceToPlayer;
public float DetectionRadius = 75;
// Start is called before the first frame update
void Start()
{
Player = GameObject.FindGameObjectWithTag("PlayerTank");
}
// Update is called once per frame
void Update()
{
DistanceToPlayer = Vector3.Distance(transform.position, Player.transform.position);
if (DistanceToPlayer<=DetectionRadius)
{
Debug.Log("Within Radius");
}
if (DistanceToPlayer >= DetectionRadius)
{
Debug.Log("Outside Radius");
}
}
}

Calculating and checking the distance of the player for every update() is not ideal. It will work, but it will do more work than it needs to when the player isn't even near it. Its not efficient.
What you may want to do if your player is a Rigidbody, is add a SphereCollider to the turret, set isTrigger=true, set the radius to be your detection radius, and handle the OnTriggerEnter() and OnTriggerExit() events to play or stop animations.
You can also add two public Animiation objects to the script, drag and drop your animations in the editor, then you can use animation.Play() and .Stop() etc. to control the animations.
Something similar to this. Not tested fully, but you can get the idea.
public float detectionRadius = 75;
public Animation activateAnimation;
public Animation deactivateAnimation;
void Start()
{
SphereCollider detectionSphere = gameObject.AddComponent<SphereCollider>();
detectionSphere.isTrigger = true;
detectionSphere.radius = detectionRadius;
detectionSphere.center = Vector3.zero;
}
private void OnTriggerEnter(Collider other)
{
if (other.gameObject.tag == "PlayerTank")
{
activateAnimation.Play();
}
}
private void OnTriggerExit(Collider other)
{
if (other.gameObject.tag == "PlayerTank")
{
deactivateAnimation.Play();
}
}
Your animations must not loop otherwise you will have to add more logic to check if animation.isPlaying and do your own animation.Stop() etc.

How to Move and Jump in Unity

I am making a First Person Shooter Game and am currently working on the jumping. I am using animation to jump as I have struggled with gravity before. However my problem is that my player cannot move if my jump script is attached to the player as well as the movement. However I know that it has nothing to do with the scripts as both scripts work but not simultaneously.
I believe it has something to do with the animation. There are 3 parts to the animation, Base, Running and Jump. If the player is moving the running animation is active, if the player has pressed the space bar then the jump animation is active. Jump animation is prioritised.
Is there any reason why the player cannot move and jump?
Here is the codes and animation controller:
Animation and Jump
public class Jump : MonoBehaviour
{
public bool run;
public float speed;
public GameObject player;
public Animator dgbanim;
public bool jump;
public float rejump;
public float rejumper;
// Start is called before the first frame update
void Start()
{
speed = 50;
run = false;
jump = false;
rejumper = 0;
rejump = 0;
}
// Update is called once per frame
void Update()
{
if (jump == false && Input.GetKey("space")) { dgbanim.SetBool("Jump", true); jump = true; rejump = 21; }
if (rejump > 0) { rejump = rejump - 1; }
if(rejump == 0) { jump = false; dgbanim.SetBool("Jump", false); }
if (Input.GetKey("w") || Input.GetKey("s") || Input.GetKey("a") || Input.GetKey("d") || Input.GetKey("up") || Input.GetKey("down") || Input.GetKey("left") || Input.GetKey("right")) { run = true; }
if (run == true) { dgbanim.SetBool("Running", true); run = false; }
else if (run == false) { dgbanim.SetBool("Running", false); }
}
private void OnCollisionEnter(Collision collision)
{
//if (collision.gameObject.tag != "EnemyBullets") { jump = true; rejump = 0; }
if (collision.gameObject.tag != "EnemyBullets") { jump = false; }
}
}
Movement
public class Movement : MonoBehaviour
{
public GameObject player;
public float speed;
// Start is called before the first frame update
void Start()
{
speed = 50;
}
// Update is called once per frame
void Update()
{
player.transform.Translate(Input.GetAxis("Horizontal") * speed * Time.deltaTime, 0, Input.GetAxis("Vertical") * speed * Time.deltaTime);
}
}

It seems like your animator have ‘apply root motion’ checked and its taking movement from animations rather than code, try unchecking it.

Animation can control some properties of a GameObject, such as the position. If you try to edit a GameObject's position in a script but an animation controls the position, the animation will override the script's changes to the position.
To see if this is the problem, you can open the animation window and select your player. If the player's position (in the inspector) is red, then the animation is controlling it.
I know of 2 ways to fix this:
Method 1 (not recommended): Edit the animation to move the root bone instead of the player
Most character models have a GameObject called "Armature" or "root" as a child. The position of your character should not be in the animation. If you need to move the character up in your animation, you can animate the "Armature" or "root" GameObject. In the screenshot below, note that in the animation window you don't see "PlayerPref: position" but instead see "Armature: position". This allows my movement script to move PlayerPref without the animation overriding the position.
Method 2 (recommended): Use the physics engine to jump
In your animation, don't make the player jump. Instead make the player "jump in place" i.e. maybe swing arms upward as if jumping but don't actually move upward. Just like Method 1, your animation should not set the player's position. The easiest way to do this is to click on "player: position" in the animation window and press delete.
Add a Rigidbody to your character. In your script:
private Rigidbody rig;
...
void Start(){
rig = GetComponent<Rigidbody>();
...
}
In your script when you trigger jumping, you can add rig.AddForce(jumpPower * transform.up);. This will make the physics system handle the jumping. If the player is jumping but there is something above, the physics engine will stop the player. With animation, the player will jump through any obstacles.

UNITY PREFABS DOESN'T SHOW UP IN GAME TAB

As you can see in the screenshoot I can't see prefabs in the game tab but only in the editor. I have made a simple function for shooting(not finished yet), it works fine, it spawns the prefabs but i can't see them in the game tab, I have already tried changing the Sorting Layer, move the camera, change Z position but nothing appen.
This is my code:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class PlayerAttack : MonoBehaviour
{
[SerializeField]
float delayBetweenShots = 0.4f;
float timePassedSinceLast = 0f;
// Start is called before the first frame update
void Start()
{
timePassedSinceLast = delayBetweenShots;
}
// Update is called once per frame
void Update()
{
Aiming();
Shooting();
}
void Aiming()
{
var objectPos = Camera.main.WorldToScreenPoint(transform.position);
var dir = Input.mousePosition - objectPos;
transform.rotation = Quaternion.Euler(new Vector3(0,0,Mathf.Atan2(-dir.x, dir.y) * Mathf.Rad2Deg));
}
void Shooting()
{
if(Input.GetMouseButton(0) && timePassedSinceLast >= delayBetweenShots)
{
GameObject bullet = (GameObject)Instantiate(Resources.Load("bullet"), transform.position, transform.rotation);
timePassedSinceLast = 0f;
}
else
{
timePassedSinceLast += Time.deltaTime;
}
}
}

The prefabs get instantiated correctly. As others suggested as well, the best way to find "lost" objects in your game is to shoot some stuff, pause the game, go into scene view, turn on 3D mode and double click one of the prefabs in the hierarchy. The camera will take you straight to your object.

How can I make a game object jump when I press a key (preferably space)?

I have this C# script attached to my main camera game object which also has a capsule collider attribute. However, it doesn't seem to do anything. How should I modify/add to this to make the camera "jump" and fall down to the ground again?
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Jump : MonoBehaviour {
[HideInInspector] public bool jump = false;
public float jumpForce = 1000f;
public Transform groundCheck;
private bool grounded = false;
private Rigidbody rb;
// Use this for initialization
void Awake ()
{
rb = GetComponent<Rigidbody>();
}
// Update is called once per frame
void Update ()
{
grounded = Physics2D.Linecast(transform.position, groundCheck.position, 1 << LayerMask.NameToLayer("Ground"));
if (Input.GetButtonDown("Jump") && grounded)
{
jump = true;
}
}
void FixedUpdate()
{
if (jump)
{
rb.AddForce(new Vector2(0f, jumpForce));
jump = false;
}
}
}
Also, I would like to have the key for this be the spacebar if possible, but whatever key works or is there already is fine. I am still learning C#, so please forgive me if the solution is obvious.

This line is most likely causing the problem:
grounded = Physics2D.Linecast(transform.position, groundCheck.position, 1 << LayerMask.NameToLayer("Ground"));`
There are 2 reason that it wont produce proper results:
You haven't setup your ground tiles or the place where you character moves to the "Ground" layer. You wont have this by default but you can add it from the Project Settings->Tags and Layers menu.
Your colliders are not close enough to the ground thus not causing collision.
Besides that it should work fine.
