Changing sprite through script?

Unity Engine
1

Hey, how do I change the GameObject’s sprite which the following script which is not working, is attached to?

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Check : MonoBehaviour
{
    //Reference
    private Scoreboard scoreboard;

    Sprite player;
    public Sprite char1;

    void Start ()
    {
        player = this.GetComponent<Sprite> ();
        // Reference
        GameObject GM = GameObject.Find("GM");
        scoreboard = GM.GetComponent<Scoreboard>();


    }

    void Update ()
    {
        if (scoreboard.Character1 == true)
        {
            player = char1;
        }
    }
}

Nothing happens when score.Character1 = true?

What are you expecting to happen? As far as I can tell all you are doing in update is assigning char1 to the player variable everyframe after scoreboard.Character1 becomes true.

If you want to see a visual representation of this, you should probably be assigning char1 to the sprite property of a UI Image. (But even then you probably only want to do this once, rather than in update).

Try changing “player” to the type SpriteRender (and the get component call, too)
Then, set player.sprite = char1;

Agreed that it would be much better to simply switch it when you change the character (or choose the character – whatever that situation is), as opposed to inside Update()

So I guess it should look something like this?

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Check : MonoBehaviour
{
    //Reference
    private Scoreboard scoreboard;

    Sprite player;
    public Sprite char1;

    void Start ()
    {
        player = this.GetComponent<SpriteRenderer> ();
        // Reference
        GameObject GM = GameObject.Find("GM");
        scoreboard = GM.GetComponent<Scoreboard>();

        if (scoreboard.Character1 == true)
        {
            set player.sprite = char1;
        }

    }
}

But I get the error: “Assets/Check.cs(22,13): error CS1525: Unexpected symbol .', expecting ,‘, ;', or =’”

No, no…See at the top you still called player (type) “Sprite”.
and you don’t want “set player.sprite = char1”
you want:

player.sprite = char1;
