Problem Changing Sprites with an Array of Sprites
I am trying to change the sprite of a dog in my game when it moves left/right. The move method works (I followed a tutorial on that), and I wanted to temporarily change the sprite of the dog to it facing left/right, depending on what direction it is walking. I created an array of Sprite objects and have inserted the corresponding sprites I want to use via the inspector. However, the sprites are not changing. I know the syntax to change a sprite is at least correct because if I paste, for example, "this.gameObject.GetComponent().sprite = dogSprites[2];" in the Update() function, it will change it. But it will not change it from within the if/else if statements I have. And yes, I have checked that the code does go into the if/else if when the dog moves by printing to the console to make sure. Any and all help would be appreciated! Here is my code:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class DogController : MonoBehaviour{
private Vector3 destination;
public float speed;
public Transform[] waypoints; // points on in the screen the dog can move to
public Sprite[] dogSprites; // different sprites the dog can change to
public void Start()
{
this.gameObject.GetComponent<SpriteRenderer>().sprite = dogSprites[2];
}
public void Update()
{
if (Vector3.Distance(transform.position,destination) > 0.5f)
{
transform.position = Vector3.MoveTowards(transform.position, destination, speed * Time.deltaTime);
}
}
public void Move(Vector3 dest)
{
Sprite temp = this.gameObject.GetComponent<SpriteRenderer>().sprite;
if (transform.position.x <= 0 && dest.x > 0) // If the next waypoint is to the right
{
this.gameObject.GetComponent<SpriteRenderer>().sprite = dogSprites[0]; // change to move-right sprite
}
else if (transform.position.x >= 0 && dest.x < 0) // If the next waypoint is to the left
{
this.gameObject.GetComponent<SpriteRenderer>().sprite = dogSprites[1]; // change to move-left sprite
}
this.destination = dest;
this.gameObject.GetComponent<SpriteRenderer>().sprite = temp;
}
}
Move method is never called, are you calling it somewhere else?
The
Sprite tempvariable stores the actual sprite of the SpriteRenderer, and you change the sprite in the if/else but in line 34 you assign the sprite to temp. You should delete that line and 24, because you are overwritting the if/else changes.
Yes, $$anonymous$$ove() is being called in a different script (sorry, I should have mentioned that). And the reason I stored a the current sprite of the dog in temp is so that the sprite can change to the one of the dog facing left/right, and then change back to the original sprite once it is done moving. Is my logic in wanting to do that flawed? Here is the code that calls the $$anonymous$$ove() method:
private void $$anonymous$$oveDogToRandomWaypoint()
{
int randomWaypoint = Random.Range(0, waypoints.Length);
dogController.$$anonymous$$ove(waypoints[randomWaypoint].position);
}
And the $$anonymous$$oveDogToRandomWaypoint() method is called in the update method of that script. (There is no problem with the movement, it works just fine!)
