Movement & idle script variables resetting

I'm currently using a PlayerController.cs script to control player movement. I am trying to have it so when they player stops moving the script saves a variable called lastMoveX and lastMoveY so the animator knows which way to keep the player model facing. When I play the game it seems that the lastMoveX and lastMoveY are resetting to 0,0 at the end of every frame, even if the player isn't moving.

Code (CSharp):

1.  
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5.  
6. public class PlayerController : MonoBehaviour
7. {
8.     public float moveSpeed;
9.     private Vector2 axisMovement;
10.     private bool playerMoving;
11.     private Vector2 lastMove;
12.     private Animator anim;
13.  
14.     void Start()
15.     {
16.         anim = GetComponent<Animator>();
17.     }
18.  
19.     void Update()
20.     {
21.         playerMoving = false;
22.  
23.         if (Input.GetAxisRaw("Horizontal") != 0){ //Horizontally
24.        
25.             transform.Translate(new Vector2(Input.GetAxisRaw("Horizontal") * moveSpeed * Time.deltaTime, 0f));
26.             playerMoving = true;
27.             lastMove = new Vector2(Input.GetAxisRaw("Horizontal"), 0f);
28.  
29.         }
30.  
31.  
32.         if (Input.GetAxisRaw("Vertical") != 0f) { //Move Vertically
33.        
34.             transform.Translate(new Vector2(0f, Input.GetAxisRaw("Vertical") * moveSpeed * Time.deltaTime));
35.             playerMoving = true;
36.             lastMove = new Vector2 (0f, Input.GetAxisRaw("Vertical"));
37.         }
38.  
39.         anim.SetFloat ("moveX", Input.GetAxisRaw("Horizontal"));
40.         anim.SetFloat ("moveY", Input.GetAxisRaw("Vertical"));
41.         anim.SetFloat ("lastMoveX", Input.GetAxisRaw("Horizontal"));
42.         anim.SetFloat ("lastMoveY", Input.GetAxisRaw("Vertical"));
43.         anim.SetBool ("playerMoving", playerMoving);
44.            
45.      
46.     }
47.  
48. }
49.  

 

Well, it looks like you're setting a "lastMove" variable onlyif there is motion, but then you're setting `anim.SetFloat` for lastMoveX and lastMoveY to the input, regardless of whether it's 0 or not. Should your SetFloats for lastMoveX/Y only be called if motion isn't 0?

 

You should cache your Input vertical and Input horizontal instead of rereading.
float vert = Input.GetAxisRaw("Vertical");
And you can get lastMoveX from lastMove.x

 

I answered a thread almost identical to this earlier. https://forum.unity.com/threads/cant-figure-out-how-to-fix-this-correctly.518676/#post-3399691
I think that link is correct and if you scroll down a bit there's an adjustment for the last moves.
