Top Down RPG sprite glitch

This is my first game so I am sorry for messy code and all of my noobishness. I learned Java and I am using this game to help me get used to C# so I know things about coding but I'm just a little lost here. If I press W&D to move my player diagonal, and then I release the last one that I pressed, then I go to that one's idle animation. Its a little complicated to explain, so I might link a video later if nobody knows what I mean. Anyway here is my animation window(It is super complicated and layed out terrible I am so sorry.) [Just Noticed left and right animations are backwards oops but I still need help here]

And then here is my code, which is super messy as I havent dont anything with animation before in my life. Just moving robots.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class move : MonoBehaviour {
6.     public float speed;
7.     Animator animator;
8.     private bool isMoving;
9.     // Use this for initialization
10.     void Start () {
11.         speed = 3;
12.         animator = GetComponent<Animator>();
13.     }
14.  
15.     // Update is called once per frame
16.     void Update () {
17.         float axisX = Input.GetAxis("Horizontal"); //horizontal movement float
18.         float axisY = Input.GetAxis("Vertical"); //vertical movement float
19.  
20.         animator.SetBool("isMoving", isMoving); // check if the player is moving
21.  
22.         isMoving = false; //set it to false by default so the ides will show
23.         if (Input.GetKeyDown(KeyCode.W)) //up animation
24.         {
25.             animator.SetInteger("walkingState", 1);
26.             isMoving = true;
27.         }
28.         else if (Input.GetKeyDown(KeyCode.D)) //left animation
29.         {
30.             animator.SetInteger("walkingState", 2);
31.             isMoving = true;
32.         }
33.         else if (Input.GetKeyDown(KeyCode.S)) //down animation
34.         {
35.             animator.SetInteger("walkingState", 0);
36.             isMoving = true;
37.         }
38.         else if (Input.GetKeyDown(KeyCode.A)) // right animation
39.         {
40.             animator.SetInteger("walkingState", 3);
41.             isMoving = true;
42.         }
43.         else if (Input.GetKeyUp(KeyCode.S) && isMoving == false) // bool test (unsucessful)
44.         {
45.             animator.SetInteger("walkingState", 4);
46.         }
47.         else if (Input.GetKeyUp(KeyCode.W) && (!Input.GetKey(KeyCode.D) || !Input.GetKey(KeyCode.A))) // and and or test (unsuccessful)
48.         {
49.             animator.SetInteger("walkingState", 5);
50.         }
51.  
52.         transform.Translate(new Vector3(axisX, axisY) * Time.deltaTime * speed); //player movement handeler
53.     }
54.  
55. }

 

I suggest looking at blend trees, as that will reduce this mess and most likely solve ur issue in the progress. Not to mention it's the "correct" way to handle this, and you should learn it the right way from the begining, makes things a lot easier

 

Ok, I haven't heard of Blend tree before. I'll look into it hopefully this fixes my mess. If you don't mind I'd like to ask where I shoudl go to learn. I know there is great documentation here, but I really like youtube tutorials. Do you know of any I could watch? I looked for a while and all I found what the setinteger thing that I am doing now. Thank you though I hope this works!

 

Sure, Here is one on blend tree anim:

His series is a good starting point. I do not agree with all his methods but thats nothing u need to worry about until way later.

 

Thank you, this will help alot.
